General Information of Fireclay brick
Our corporation producesa comprehensive range of Fireclay bricks, with 30% to 55% alumina content, allof these bricks exhibit excellent performance.
Our Fireclaybricks are the final result of blending excellent fused alumina and silicon asthe main raw materials with cutting-edge technology, adding superfine powder,after mixing, drying, forming, in the high temperature shuttle kiln. We ensureyou that the Fireclay Bricks made by us possess high quality standard and havegone through all the complicated quality control parameters. Their durabilityand strength adds life to the structure and they have the capacity of bearinghigh temperature.
Feature of Fireclay Brick
Resistant tothermal shock, abrasion, chemical attack
High ability foranti-abrasion during work
Low shrinkagedegree under high temperature so as to maintaining integrity of the furnacelining
Low apparentporosity, and low Fe2O3 content to reduce the carbondeposit in the blowhole and avoid the bricks broken in case of expansion
Applications of Fireclay Brick
Fireclay brick is mainlyused in the part of throat, stack, hearth, bottom for blast furnace and thestack for a big blast furnace.

- Q:How good is the hardness of corundum refractory brick?
- The basic materials of corundum refractories are fused corundum or sintered corundum. the refractory brick containing more than 90% of Al2O3 is called corundum refractory brick. so, corundum refractory brick. Corundum has a high hardness (9 level of Mohs hardness) such as zirconium corundum refractory brick. Corundum refractory brick is resistant to acid well and melting point is also high, also known as pure alumina refractory brick products, , it has a good effect. These are closely related with the structure of the Al - 0 key, titanium corundum refractory brick, and other basic slag. It is used in high temperature oxidizing atmosphere or in reducing atmosphere. the metal and glass solution have good stability. a-Al2O3 is the main material of high temperature refractory brick and high temperature electrical insulating material .
- Q:Can lime rotary kiln refractory brick kiln be hung with klin coating?
- Should prevent the rotary kiln from being damaged; why hang kiln coating on the rotary kiln; try to avoid the big knot; 5; maintain the integrity of flame shape; burn top fire; should be hung; to prolong the service life of the refractory brick; steel plate is unable to withstand the high temperature, strengthen calcination control; adjust the high temperature region; let the big block out in time; avoid burning the fire. . Preparation equipment manufacturers 4, find the correct operating parameters of rotary kiln according to the experience; often keep the temperature above 1450 DEG C in the container; what is the reason for the rotary kiln coating; and add a layer of strong protective layer on the surface; the cylinder of the rotary kiln cylinder is made of steel plate; this is only the first step to determine the safe operation of the rotary kiln; avoid damage or smash the rotary kiln coating. 2; measures should be taken to prevent the kiln coating fall off because of the stop of the kiln and the changing of sudden hotness and sudden cold; burn the top fire; raw materials of appropriate preparation ingredients . We need to know the the rotary kiln, make up in time. The fire resistance and thickness of refractory bricks are limited. 6; in the inside of the building with a layer of refractory brick. 8. Observe and adjust frequently; and can reduce the heat loss outward; control the fire; we take 8 steps to perfectly protect the rotary kiln: how to protect the kiln skin that is hung well; improve coal mouth structure; important operation method of long-term effective rate of safety energy-saving ball mill the work will be interrupted; deterioration, strengthen equipment maintenance of retary kiln, after hanging the rotary kiln skin; ensure clinker grain is fine and uniform; improve the thermal efficiency for the benefit of kiln skin sticking, must treat in time ;
- Q:Which is best of refractory brick press machine?
- Rub press machine have been forced out. Without permanent magnet. The electric screw press machine is suitable for the forming of refractory bricks. Use Kehui switch reluctance to servo motor to drive electric screw press machine, have the ability of high quality electric screw press machine, no water cooling, high efficiency and energy saving, green and environmental protection.
- Q:how much is the content of the high alumina of refractory brick?
- linear?change?on?reheating is small and Slag resistance is good, matte smelting, good thermal shock resistance used refractory materials should be resistant to high temperature: In front of the furnace, the temperature can reach 1800, copper blowing. The maximum temperature in the smelting furnace area is on the top, pyro-refining and electrorefining, magnesia chrome brick, magnesia chrome castable, magnesia alumina brick. The commonly used refractory materials is direct-bonded?magnesia-chrome?bricks, which has large volume density. manufacturing technique of copper smelting consists of five parts, Clay brick
- Q:MU10 what are the non clay solid bricks?
- Clay solid brick with clay and is needed by adding admixture as raw materials, solid bricks by water mixing, molding, high temperature calcination made, mainly used for masonry bearing and non bearing wall, wall materials is a kind of widely used.
- Q:What are required for high temperature refractory bricks?
- Volume density, aluminum content, soft bearing, thermal shock
- Q:What is the problem about splintering when the refractory brick is fired?
- There are many bubbles inside the refractory brick, it is also possible that the brick itself is not up to the standard about volume density, then refractory brick fragmentates. There are many reasons, may be in the process of repression
- Q:What are 85 bricks, 95 bricks and standard bricks? What are the specifications?
- Clay to clay (including shale, coal gangue powder) as the main raw material, through mud processing, molding, drying and roasting and.
- Q:What matters should be noticed when using clay refractory bricks in a glass kiln?
- There are a variety of products for the production of shaped and unshaped refractory clay, such as blast furnace insulation and high alumina bricks. Brick products include refractory clay bricks, plastic materials for overload, refractory clay and high alumina casting materials, etc.. In the amorphous part, if to support the horizontal induction furnace and the straight induction furnace lining, such as refractory clay and high alumina plastic
