Q:The stove which made of refractory bricks and fireclays will produce cracks after being used. How to solve this problem?
The use of low expansion materials will be better. But as for the stove, the appearance of crack is attributed to the selected materials or the environment. And when the temperature is not high, there still seems to be crack, so through expansion joint reservation, not allowing itself to crack
Q:What is the relationship between the firing process and the manufacturing technique of fireclay bricks?
Q:can diatomite brick be used as thermal insulation refractory brick?
yes, it has good thermal insulation the raw material is cheap, diatomite brick is a kind of thermal insulation refractory brick with good performance.
Q:What kind of material is good to be laid on the kiln car, refractory brick?
Use blankets to suspend ceiling, and modules for wall
Q:Is the thickness of the kiln lining and the refractory brick the same concept?
This is certainly not the same. The thickness of the refractory brick can be arbitrary, the thickness of the kiln lining is generally designed according to requirement
Q:What are the differences between fireclay brick and high alumina refractory brick?
One is the high alumina, solid and hollow respectively, fused mullite as main raw material made of high-grade refractory materials, strong corrosion resistance, has the advantages of through mud treatment, good thermal shock stability. Good resistance to slag, used to build steel making furnace and glass furnace. High alumina brick is a kind of refractory material. Clay brick is also known as sintered brick, electric smelting corundum and low creep high alumina brick [1] with high grade bauxite, this kind of refractory brick's main component is AL2O3, which is suitable for large and small buildings with artificial bulk. High thermal stability. A neutral refractory material with more than 48% of alumina oxide content, clay brick has clay (including shale, molding, coal gangue and other powder) as the main raw materials, cement rotary furnace lining. The product has a small high-temperature creep, one is clay. From bauxite or other high content of aluminium oxide raw materials' forming and firing, refractoriness is above 1770 deg. High R.U.L and medium-sized hot-blast furnace is different firstly in the material, forming from drying and roasting
Q:Can someone tell me the refractory brick in the boiler mixed with what material to build the wall, and what proportion?
Go to the refractory factory to buy some refractory clay that has the same texture of refractory bricks, the general boiler use clay refractory mortar.
Q:What is the difference between a clay brick and a red brick?
Clay bricks burn red and red brick. Burnt blue. Green brick.Clay bricks are called sintered clay bricks.The construction methods are the same as those of the two. No difference.
Q:What are the main constituents in non clay brick sintering?
Sintered clay brick, it is through the mining soil, brick making, modulation, drying, roasting and cooling produced, roasting coal amount is solid sintered clay brick coal blending amount of 20-60%, the amount of coal to ensure product's surface.
Q:What is the specific heat of a refractory bricks (clay)?
Approximately it's about 2000; M3 specific heat is wrong with this argument, two degree clay is 1730 degrees, three degree clay is 1690 degrees, clay bricks are mixture, bulk density, 1900KG/, only elementary substance has specific heat refractoriness.
