Q:How to judge the quality of brick, clay brick, high alumina brick furnace from the appearance?
Mainly depends on the color and density of brick. Another black clay brick and brick with iron oxide formation and how much the size of bricks
Q:Which material is good for furnace refractory?
Acid refractory with silicon oxide as the main component, are commonly used in brick and clay brick. Silica is silica containing more than 94% silica products, raw materials used in silica, silica and other waste, the acid resistance of slag erosion ability, high load softening temperature, volume shrinkage after repeated burning, or even a slight expansion; but it is vulnerable to the erosion of basic slag, thermal shock resistance is poor. The brick is mainly used for thermal equipment of glass furnace, coke oven, acid furnace etc.. Clay brick with refractory clay as the main raw material, containing 30% to 46% of alumina, weak acid refractory material, heat shock resistance, resistance to acid slag, widely used.
Q:What are the materials for refractory materials? What are their names?
Acidic materialMainly siliceous materials, such as quartz, tridymite and cristobalite, chalcedony, flint, opal, white quartzite, silica sand, diatomaceous earth, silicon oxide contained in these siliceous materials (SiO2) at least 90%, pure raw materials are silicon oxide as high as 99% or more. Siliceous materials at high temperature is the acidic nature of chemical dynamics, when the presence of metal oxide, or when in contact with the chemical reaction, and combined with a fusible silicate. Therefore, if there is a small amount of metal oxide in siliceous material, it will seriously affect its thermal resistance.
Q:The formula in the refractory brick, and firing curve, who knows?
By silica powder, 81-85%, perlite 15-19%, plus the total weight of the main raw materials of the following accessories
Q:The specific content is what gb/t2608-2012 brick
The provisions of the brick classification, technical requirements, test methods,
Q:Why will expand when heated brick
In the process of SiO2 drying, the four crystalline transformation points of 117, 163, 180~270 and 573 DEG C are found, among which the volume expansion caused by the 180~270 is the largest.
Q:What is the effect of the content of silicon nitride in silicon nitride bonded silicon carbide brick on the use of electrobath? Thank you
Small fluctuations in the chemical composition do not have a significant effect on use. The key is the operation of the electrolyzer in production to determine whether the side wall will be damaged.
Q:What is the main material of silica brick
An acid refractory consisting mainly of quartz and square quartz and a small amount of residual quartz and glass.
Q:Semisilica brick, clay brick, high alumina brick and what is the difference?
This is a kind of refractory material is divided into three types: semisilica brick (A12O315 ~ 30%), clay brick (A12O330 ~ 48%), high aluminum brick (A12O3>48%).
Q:How to improve the thermal conductivity of the coke silicabrick rate?
To improve the thermal conductivity of silica brick for coke oven rate method:Manufacture of high density and high thermal conductivity of silica brick, adding additives such as CuO, Cu2O, TiO2, Fe2O3, (FeO), can improve the thermal conductivity of silica brick.
