Fire clay bricks manufacturing process

Generality High Alumina Brick &Clay Brick

The fire clay bricks manufacturing process includes seven steps.

1)Obtain raw materials. tundish well block The clay for manufacturing bricks is obtained from the ancient soil deep under the earth’s surface. The soil in this layer is slightly deeper in color

than the topsoil and was formed about 80,000 to 120,000 years ago. At that time, the climate is warm and humid and plants are diverse and lush , which mades the soil in this

period soft and sticky and a Clay, High Alumina insulating bricks good raw material for fireclay bricks.

2)The clay is stacked in the open air for up to six months to make its inner structure loose. Then it is zirconium sizing nozzle crushed and screened to get the pure fine clay.

3)Add water to the clay and then repeat kneading to make it into thick mud. This step is very important for the finished products.

4)Puur the mud into the mold. tundish coating Compact it and then remove the remaining mud with a wire bow.

5)Release the green body from the mold and dry it in the shadow to avoid cracks and deformation caused by exposure to the sun.

6)After drying, fire bricks in the kiln. This process is the most important part of the brick-manufacturing process.

7)After ten days of firing, the green body is basically sintered. if stopping heating at this time, the outside air may come into the kiln and make the bricks oxidized into red

bricks. in order to prevent oxidazing, seal the kiln roof with clay.

Do you know how the slay ball content influences quality of ceramic fiber paper

The slay ball density is 10 times more than ceramic fiber paper, if the content is too high, it will change the original arrangement structure of the fiber.Ceramic fiber paper’s refractory fiber board density range is 200±20kg/m3. Slay ball’s density range is 2800-3200kg/m3, is 10 times more than ceramic fiber paper. So the content of slay ball directly influences the quality of ceramic fiber paper.The high insulating castable content means lots of crystal grain in ceramic fiber paper, making the flatness and evenness worse. From the surface, some small raised can be seen. The internal fiber bulk’s structure of ceramic fiber paper with good evenness is tight and closed, so the thermal insulation is better. refractory material The internal fiber bulk’s structure of ceramic fiber paper with high slay content becomes worse , holes becomes larger, so making the alumina brick closure property worse, convection heat transfer increases, total heat transfer coefficient increases. All of the above lead to the worse of thermal insulation.The slay ball change the change the original arrangement structure of the fiber, widen the space of fibers, heavily lowering the strength of ceramic fiber paper, once the strength becomes lower, it will leading to the abradability and electrical insulation of ceramic fiber paper worse,refractories reducing the heat insulating ability and utilization rate of ceramic fiber paper.So, we can see it that the amount of slay-removal steps directly influences the slay ball content, then influences the quality of ceramic fiber paper.Changxing ceramic fiber paper is produced by 9 slay-removal steps, the slay ball content is lower than similar products, so the abradability and electrical insulation of ceramic fiber paper is better.

ceramic fiber module has more technology advantages

(1) low density. Ceramic fiber fold module furnace lining is lighter as 70% than light-weight insulation brick lining, high insulating brick as 75_80% than mortar lining, so that it will reduce the stress on the steel structure of furnace, extend furnace’s operated time.

     (2) low heat capacity .castable refractory material  The heat capacity of furnace lining material is direct proportion to the weight of furnace lining, low heat capacity means that furnace absorb less heat during operated, and temperature rise fast. Heat capacity of ceramic fiber is just as 1/7 as light weight clay ceramic brick, it reduces energy consumed heavily, especially it makes a great effect for heating clay insulating bricks furnace’s energy saving.

     (3)Low thermal conductivity. When Ceramic fiber module is in 400C temperature, thermal refractory fiber board conductivity is less than 0.11, in 600, is 0.22, in 1000, is less than 0.28. Is about 1/8 as light clay brick,

     Great thermal shock resistance and mechanical shock resistance. Ceramic fiber module is pliable, it has a great resistance to heavy mechanical shock and thermal shock.

     (5)Simple construction. insulating castable Its special anchor type solves the problem that constructed slowly by traditional module, folded module will be inflated and extrude each other after untied. Furnace lining can be used at first time after construction without drying and protect.

     Till now, energy-saving, environmental protection and voiding glob warming has became the focal refractory material point in the whole world, material costs will become a bottleneck in the development of the steel industry. So that people care the heat loss in industry furnace more and more.According to the statistics, continuous system furnaces with Changxing ceramic fiber module, saving rate is 3% to 10%;batch furnaces and thermal equipment energy-saving rate is 10% to 30%, or even higher.

     Modular ceramic fiber alumina brick can extend the use of the kiln lining life and reduce the furnace heat loss, a new generation of applications crystalline ceramic fiber composite module can not only improve the cleanliness of the furnace, to improve product quality, but also can play a good energy saving effect. Therefore, industrial furnaces, especially in the steel industry furnace should be designed to maximize the use Changxing ceramic fiber modules as furnace linings, should make full use of the old furnace repair time, will lay bricks or layers to the ceramic fiber blanket lining modular structure, which is also an important measure to iron and steel industry to achieve sustainable development.

Ceramic fiber module application（2）

Changxing ceramic fiber folded covering agent blanket module adopts Changxing ceramic fiber blanket, folded into accordion-like according to certain width, then embed the anchoring into module and folded and compressed. Changxing modular fiber do not contain any binder. Folded blanket will jam each other in different directions without gaps after the lifting of the strapping. Figure 2 schematic for folding compression module.

     Installation method firebrick refractory sale of Changxing ceramic fiber module in furnace wall, as shown in figure 3. Before module installation, it is need to welding short anchors (head with thread) on furnace wall. And then covered with a layer ladle slide gate of normal Changxing insulation rock wool, thickness 15~20 mm. The module back bead at the center of the hole and short anchor pin alignment, make anchor nail head into the module on the hollow tube, will cooperate with anchor nail head screw nut in a socket wrench head sleeve, insert the socket module of hollow casing, rotate the wrench, tighten nut to anchor nail head. Nut, ceramic fiber felt screw anchor nail and back bead connected in this way, thus the module fixed on the furnace shell.

      Reinforcement ladle castable plate on the back layering is very important, playing the role of reinforcement of bolted joints. Figure 4 shows the shape of after module installation. When the module is installed, folding directions must stagger, Horizontal and vertical module must be installed interval. The aim is to: when all installed, removed the bundle after, let module can free expansion, will fill the gap.

     Changxing refractories ceramic fiber module installation process is simple and convenient, But in strict accordance with the requirements of each step,  Suppose if welding short anchor nail is not secure, will cause the module overall fall off wall collapse and other major accidents, if the direction of module folding did not stagger when installation can lead to a module cannot be subject to uniform pressure and mobility.

Refractory Material-Silica Brick

Silica brick belongs to refractory material, with acid erosion ability, its thermal conductivity, high refractoriness under load, generally less than 1620 DEG C, only the ratio of its low refractoriness 70~80 C. The thermal conductivity of silicon increases with the increase of the working temperature, no residual shrinkage, in the baking process, the silica volume increases with temperature. So, brick is the ideal of Clay, High Alumina insulating bricks the coke oven refractory products, an important part of the large and medium (such as coke oven combustion chamber, ramps and regenerator) with brick masonry.

High strength, abrasion resistance, low resistance to carbon deposition of iron oxide, strong ability.

In the drying process, magnesia carbon brick brick maximum expansion occurs in 100~300 DEG C, 300 expansion before the total amount of expansion is about 70%~75%. The reason is that SiO2 appears in the baking process in 117 C, 163 C and 180~270 degrees and 573 degrees four points between the crystal transformation, 180~270 C, caused by the volume expansion of the largest square quartz.

Key to determine the thermal stability of ladle gunning mix silica brick quality is true density, true density size is one of the important signs of the transformation of quartz. The true density of silicon is smaller, the lime into more completely and the residual in the oven in the process of expansion is small.

In the brick, the scales of quartz crystal true density, linear expansion rate, thermal stability such as quartz and quartz, slag resistance, good thermal conductivity, high refractoriness under load, the volume is the most stable in the form of quartz. Good brick firing, tridymite content is the highest, accounting for 50%~80% times; cristobalite, accounted for only 10%~30%; and quartz and glass phase content in the range of 5%~15%.

What is the organizational structure of the high alumina brick

High alumina brick have very good ability of anti-acidity, anti-metal fluid corrode and anti-oxidation.

Generally speaking, the structure of high alumina brick is composed of solid material and gaseous hole. Porosity is an important factor to affect the properties of high alumina brick at room temperature and high temperature, especially at high temperature, the resistance to corrosion of the refractory brick is greatly reduced. The original is trapped:

pore forming high alumina brick molding Clay, High Alumina insulating bricks material in the air is not completely excluded; material removal of water left after space; calcining is not sufficient, some decomposition salts were not decomposed completely, should not completely burning burning ingredients; material composition is not uniform, high temperature sintering shrinkage uneven.

But in some light magnesia carbon brick high alumina refractory brick and fire brick production, it also introduced some specific holes evenly distributed. The existence of the air hole ladle gunning mix has a direct influence on the porosity, water absorption, bulk density and air permeability of high alumina brick.

The difference between ceramic fiber paper and ceramic fiber cloth

Ceramic fiber paper and ceramic fiber cloth are refractory insulation materials, can be used to heat insulation, how to better distinguish between ceramic fiber paper and

1.Building material industry,kiln,heating equipment and the inwall of high-temperature pipe line2.Chemical industrial high temperature of reaction equipment inwall3.Power plant ,gas turbine engine and heat insulation of unclear power4.The fire proof of high-rise building5.Used to make gasket6.High-temperature filter material

ceramic fiber cloth, according to the accumulation and experience, can be in several aspects to distinguish:

1 appearance. ceramic fiber felt cloth has a clear grid like, ceramic fiber paper is very little, and even no grid.
2 density. Ceramic fiber paper is greater than the density of ceramic fiber cloth.
3 thickness. Ceramic fiber paper high insulating brick is the most thin can be done 0.5mm, ceramic fiber paper can not do so thin, generally the most thin also has 2mm.
4 stand. Ceramic fiber paper can be like in our life that can be placed on the A4 paper, mold, stand up. refractory company Ceramic fiber cloth is like our life with cloth, very soft, does not

have to stand.
5 tear resistance. The toughness of ceramic fiber paper is not good with ceramic fiber cloth.

Whycic fiber module is widely applied in furnace

Ceramic fiber module is lighter than light weight insulation brick and can reduce the load of the furnace. It has lower heat capacity which means less heat absorbed by the

The construction is convenient, high strength, low thermal conductivity, good thermal insulation effect.

furnace in the reciprocal Clay, High Alumina insulating bricks operation and faster heating. It has white color and regular size and can be fixed directly to the industrial furnace.

Ceramic fiber magnesia carbon brick module has excellent chemical stability, thermal stability and flexibility. It is in pre-compressed state. After masonry is completed and the banding is lifted,

the expansion of ladle gunning mix ceramic fiber module can make the lining seamless and compensate the shrinkage of the lining, which can improve the thermal insulation and the integrity of the

furnace. The lining requires no drying and maintenance and can be used directly.
