In order to improve the anti-corrosion iron slag in the iron trough castable refractory, silicon carbide powder and anti-oxidants are usually added in it.
With the increase of the amount of silicon carbide, castable gravity values decrease, after 1450 ℃ burning, the flexural strength is increasing, as well as the porosity. 
When the working silicon carbide amount is less than 15%, castable apparent porosity is small, it can flow freely.
At the same time, users should choose a high content of silicon carbide with fewer impurities, formulated refractory castable gravity.
With the increase of the amount of silicon carbide, castable gravity values decrease, after 1450 ℃ burning, the flexural strength is increasing, as well as the porosity.
Is well known, the shape of silicon carbide is flakes which is difficult to fill the voides between the particles in the matrix, resulting poor fluidity.
Above 1300 degrees, the surface of the silicon carbide particles is oxidized to form a protective film of silicon dioxide,
Meanwhile, the silica reactes with the matrix aluminum oxide, produces mullite accompanied by volume expansion,
and therefore gravity refractory castable strength continues to increase. Although the reaction product can fill part of the porosity castable,
However, the oxidation of silicon carbide and its own high-density ratio are small compared with corundum and aluminum material,
thus resulting in the increase of castable porosity, which is not conducive to slag resistance.
