Silicon carbide refractory brick is the first material we check when the kiln wear zone gets too hot and harsh.
1.Core silicon carbide refractory properties
The main thing about the properties of silicon carbide bricks is how they survive the worst heat and abuse. The silicon carbide brick working temperature is very high, normally running stable at 1500°C to 1650°C.
For silicon carbide brick temperature resistance, it handles sudden hot and cold changes easily without peeling. We test the silicon carbide brick thermal shock resistance in our workshop by water quenching, and the structure stays solid.
Also, the silicon carbide brick high temperature strength means the brick won’t crush even when you load heavy tons of material on top of it inside the furnace.
2.Why pick our SiC bricks?
Heat transfer is another big reason.
The silicon carbide brick thermal conductivity is very fast, way faster than a standard high alumina refractory brick for furnace roof. This high silicon carbide refractory brick thermal conductivity helps cooling walls work better and saves fuel.
In the heavy friction areas, the silicon carbide brick wear resistance is incredible. Scraping metal or sliding solid fuels will not rub it away.
You also get great silicon carbide brick corrosion resistance against acid slag and gas. Plus, the low silicon carbide brick thermal expansion means your furnace wall stays tight and won’t bulge out after firing.
If your kiln section is less harsh, you might just use a high alumina brick for cement kiln transition zone, but for the worst spots, SiC is a must-have.
3.Main uses in the factory
So, where exactly do you use them?
Because of all these hard silicon carbide fire brick properties, we ship a lot to zinc smelting plants, aluminum melting furnaces, and for building ceramic kiln furniture.
The strong SiC brick properties stop chemical attacks, so they are the best choice for blast furnace bellies and municipal garbage incinerators. Many of our clients buy them together with chrome corundum castables to line different parts of the same project.
Knowing the exact silicon carbide refractory properties saves your maintenance budget. At Ruitai Lianxin, we control the raw grains and pressing tons ourselves. If you need a direct factory price for your project, send us the sizes you need. We will give you the right refractory materials solution.
