Compared with other amorphous materials, refractory ramming materials are dry semi-dry loose. Most of them have no cohesiveness before forming. Therefore, only strong ramming can obtain a dense structure. Compared with castables plastics, magnesium-calcium synthetic sand ramming materials have higher stability corrosion resistance at high temperatures. But it also depends on the choice of high-quality materials, the reasonable ratio of pellets powders also has a lot to do with. Ramming material castable are both refractory materials, but there are also differences between the two: 1. The difference in raw material composition: the ramming material is mainly made of aggregates powders with a certain particle size, plus binders additives. Unshaped refractories mainly constructed by manual mechanical ramming. Ramming materials include corundum ramming materials, high-aluminum ramming materials, silicon carbide ramming materials, carbon ramming materials, silicon ramming materials, magnesium ramming materials, etc. Like the electric furnace bottom ramming material, silicon carbide, graphite, electric calcined anthracite as raw materials, mixed with a variety of ultra-fine powder additives, fused cement composite resin as a binder made of bulk materials. It is used to fill the gap between the furnace cooling equipment the masonry the filler for the masonry leveling layer. Castable is a kind of granular powdery material made by adding a certain amount of binder to refractory materials. With high fluidity, it is suitable for unshaped refractory materials formed by casting
.
The three major components of the castable are the main component, the external component the impurities, which are divided into: aggregate, powder binder. The raw materials of aggregate include silica, diabase, andesite waxstone. Compared with other amorphous materials, refractory ramming materials are dry semi-dry loose.
