Silicon Carbide Ramming Mass Supplier

Silicon carbide ramming mass is a bulk material made of silicon carbide, graphite, and electrically calcined anthracite as raw materials, mixed with a variety of ultrafine powder additives, and fused cement or composite resin as a binder. It is used to fill the gap between the furnace cooling equipment and the masonry or as a filler for the masonry leveling layer.

Sic ramming mass production ratio

1. Silicon carbide powder is the main component that provides hardness and durability to the ramming material.
2. Binder: Commonly used binders include resins, ceramic binders, ва ғайра., which are used to bond silicon carbide powder together and keep it in a certain solid form.
3. Lubricant: Lubricants such as polyvinyl alcohol and beeswax are usually used to reduce the friction between silicon carbide powders and improve the fluidity of the ramming material.
4. Mold release agent: used to apply to the ramming material mold to facilitate the smooth removal of the ramming material from the mold.
5. Other additives: According to needs, some other additives, such as pigments, fillers, ва ғайра., can be added to improve the performance of the ramming material or meet specific needs
