General Information of Fireclay brick
Our corporation produces a comprehensive range of Fireclay bricks, with 30% to 55% alumina content, all of these bricks exhibit excellent performance.
Our Fireclay bricks are the final result of blending excellent fused alumina and silicon as the main raw materials with cutting-edge technology, adding superfine powder, after mixing, drying, forming, in the high temperature shuttle kiln. We ensure you that the Fireclay Bricks made by us possess high quality standard and have gone through all the complicated quality control parameters. Their durability and strength adds life to the structure and they have the capacity of bearing high temperature.
Feature of Fireclay Brick
Resistant to thermal shock, abrasion, chemical attack
High ability for anti-abrasion during work
Low shrinkage degree under high temperature so as to maintaining integrity of the furnace lining
Low apparent porosity, and low Fe2O3 content to reduce the carbon deposit in the blowhole and avoid the bricks broken in case of expansion
Applications of Fireclay Brick
Fireclay brick is mainly used in the part of throat, stack, hearth, bottom for blast furnace and the stack for a big blast furnace.

- Q: Is there a big difference between two high alumina brick and one high alumina brick?
- The difference between the two kinds of high alumina bricks is great. I perennial in Zhengzhou was responsible for the production and sale of colt refractories
- Q: What is the heat preservation material used in a laboratory furnace?
- Thermal insulation cotton is a high-purity clay clinker, alumina powder, silica powder, chromium sand and other raw materials in the industrial furnace melting at high temperature, forming fluid. Then, compressed air is used to blow or use the wire throwing machine to turn the yarn into a fiber shape. After the cotton collector is collected, the cotton is formed into a heat preservation cotton.The high alumina brick is usually made of high alumina clinker with small amount of clay. After grinding, the high alumina brick is poured and shaped in the form of slurry by the way of gas generation or foam, and it is burnt at 1300~1500 DEG C. Sometimes industrial alumina can be used instead of some bauxite clinker. Used for lining and insulation of masonry kilns, as well as for areas where there is no strong, high temperature molten material erosion and erosion. When contacting the flame directly, the surface contact temperature shall not be higher than 1350 degrees centigrade.
- Q: What refractory material does cupola lining use?
- Materials defined as physical and chemical properties that allow them to be used in a high temperature environment are called refractory materials. Refractory materials are widely used in metallurgy, chemical, petroleum, machinery manufacturing, silicate, power and other industrial fields, the largest amount of metallurgical industry, accounting for 50% ~ 60% of the total output.
- Q: Application characteristics of high alumina brick
- Reheating line change. If the firing temperature of high alumina brick products is enough and the firing time is enough, the volume is stable, the change of the reheating line is small; on the contrary, the residual shrinkage of clay brick products is caused by recrystallization.
- Q: What is the standard size of high alumina brick?
- Standard brick: 230 x 115 x 65; four points: 230 x 115 x 40; three points: 230 x 115 x 30; 150 x 120: Brick gable. Light weight brick 1 to 1.7 kilograms; heavy clay superscript brick weighs 3.75 kilograms; light 30 plates 0.79 kilograms; light 40 plates, 1.05 kilograms.
- Q: What is the difference between high alumina brick and clay brick?
- Lightweight high alumina bricks are usually made of high alumina bauxite clinker with a small amount of clay. After grinding, the bricks are poured and shaped in the form of slurry by gas or foam method. They are fired at 1300~1500 DEG C. Sometimes industrial alumina can be used instead of some bauxite clinker. Used for lining and insulation of masonry kilns, as well as for areas where there is no strong, high temperature molten material erosion and erosion. When contacting the flame directly, the surface contact temperature shall not be higher than 1350 degrees centigrade.
- Q: What is the apparent porosity of high alumina brick?
- Total porosity is porosity refers to the total volume of sample porosity in the percentage of total volume of samples. Apparent porosity refers to the percentage of the total volume of openings, pores, and total specimens in the sample.
- Q: How to reduce the harm caused by two times mullite in high alumina refractory material
- Prolong the sintering time and adjust the aluminum content of the high alumina brick.
- Q: How does the physicochemical index change when the high alumina brick is used at high temperature?
- When the high alumina brick is used at high temperature, the physical and chemical indexes and other constants will not change if the temperature is in the physical and chemical indexes and the softening temperature of the load.
- Q: How can the refractory brick blast furnace be pulverized and pulverized enough not to be taken away by the wind?
- The gas will directly lead the dome combustion, in order to ensure good mixing, complete combustion of gas and air in a short time, the combustion capacity of short flame or flameless combustion burner, commonly used for semi jet short flame burner.
