Q:What refractory materials are used in industrial furnaces?
The working conditions of industrial furnaces should first be investigated thoroughly, and the primary and non essential factors affecting the construction of furnace materials shall be analyzed. Focus on thinking, the temperature change condition, temperature bump slag properties, furnace atmosphere, heat insulation, impact wear and other special requirements, to ensure the quality of the life and product.
Q:What problems should we pay attention to in the use of fused zirconia corundum brick (fused zirconia corundum brick) in glass furnace?
Cast brick and clay brick masonry contact, eutectic phenomenon will occur at 1300 degrees Celsius, the selection of refractory materials, should avoid eutectic phenomenon serious two kinds of refractory materials such as brick masonry contact, in the following cast brick, the most vulnerable to erosion fused zirconium corundum brick.
Q:What are the main constituents of refractory bricks
Corundum refractory brick and corundum brick is a kind of refractory brick with AL2O3 content not less than 90% and corundum as its main phase. It can be divided into sintered corundum bricks and fused corundum bricks.
Q:What kind of refractory material will be used in the glass kiln
High temperature & glass corrosion performance of the brick is slightly lower than that of chromium oxide, also by isostatic pressing forming method, its technical indicators ZrO2>65%, <2.0% porosity, volume density of about 4.25g/cm3, the temperature in E glass is higher than 1370 DEG C have erosion. Used in the E glass melting pool unit kiln glass temperature slightly lower at the end of the transition path, forming the bottom of the pool and forming path path flow tank and bushing support brick etc.. In addition, the dense zirconia brick is used as the backing brick of the dense chrome brick.
Q:What refractory materials are adopted in each part of the blast furnace
The furnace throat is a part of the direct impact and friction when the burden drops, and the high density and high alumina brick is usually adopted. The upper and middle shaft temperature is only 400~800 degrees, the parts with high alumina brick and sillimanite brick.
Q:Is liquid phosphoric acid two aluminum hydrogen flammable?
Two aluminum liquid hydrogen phosphate using spray paint, cement, refractory castable and binder for foundry industry, mainly used in refractory industry corundum, chromium corundum nozzle coal water slurry gasifier with chromium aluminum zirconium corundum brick production.
Q:How do corundum bricks bind?
High temperature bonding clay can be used for bonding masonry
Q:How to improve the induction furnace campaign, from the promotion of refractory life start
According to the use of atmosphere, choose the appropriate spraying materials, such as infrared radiation paint
Q:What is the main component of corundum?
Corundum is the main component of Al2O3, often containing trace impurities such as Cr, Ti, Fe, V and so on.
Q:What are the refractory materials?
Not a good answer. You can sort out, such as: neutral, alkaline, acid refractory. Different kinds, of course, raw materials are different.For example: MgO-C brick basic refractories: magnesia (fused, high purity graphite) + + + phenolic resin additives (silica fume or aluminum or silicon carbide or high temperature asphalt) etc..
