Q:What are the application of used refractory brick pieces?
auxiliary material made of refractory bricks or refractory is not as good as that of bauxite.
Q:How many bricks, mortar and how much wear and tear does one side of the clay brick masonry need?
In the standard brick wall of 1M3, the standard brick occupies 516.53 pieces of *0.24M*0.12M*.053M=0.788M3
Q:Classification of refractory bricks
Q:does furnace use refractory cement to make refractory bricks?
You can use fireclay, refractory cement is commonly used to arch. fireclay has good viscidity, it is handy to use.
Q:What are the main raw materials of refractory brick and runner brick?
Types of refractory bricks are divided into low-grade and high-grade. generally, siliceous, semi siliceous and high aluminous runner brick brick have higher requirements. If it needs to contact melting in high temperature molten steel directly, then it is high alumina(the main raw material is clinker of bauxite with high alumina, corundum( brown corundum and white corundum), the refractoriness is high, lower than 1580 DEG C temperature, but the actual using temperature reaches 1630 DEG C
Q:What should be paid attention when the refractory brick kiln furnace reaches a certain service life and will be removed?
Q:What is the difference between the refractory bricks, hand-made bricks and the machine pressure bricks?
The density of hand-made is not enough, it's light, while the density of machine pressure is high, it's heavy, each has their own benefits
Q:What are required for high temperature refractory bricks?
good thermal shock resistance:
Q:What types of building blocks do you have?
Ordinary housing: building brick (clay brick), and non sintered brick (sand lime brick, fly ash brick, cement brick, etc.)
Q:can the red brick be used as refractory brick?
Can not replace! The high temperature will make it burst. Coefficient of thermal expansion is not enough
