Tamping material refers to the use of tamping (artificial or mechanical) construction, dry materials and hardened under the heating effect of higher than normal temperature unshaped refractories. It is made by mixing refractory aggregate, powder, binder, additive with water or other liquid with a certain gradation. There are high alumina, clay, magnesium, dolomite, zirconia and silicon carbide - carbon refractory ramming materials according to material classification.

Raw materials of ramming material are silicon carbide, graphite and electric calcined anthracite, which are mixed with many kinds of superfine powder additives and bonded by electric melting cement or composite resin. It is used to fill the filling material between furnace cooling equipment and masonry gap or masonry leveling layer. The ramming material has good chemical stability, erosion resistance, wear resistance, peeling resistance, heat shock resistance, and is widely used in metallurgy, building materials, non-ferrous metal smelting, chemical, machinery and other manufacturing industries!

Acidic, neutral and alkaline ramming materials are widely used in Coreless medium frequency furnace and cored induction furnace as medium frequency ramming materials for melting gray cast iron, nodular cast iron, calcinable cast iron, vermicular cast iron and cast iron alloys, molten carbon steel, alloy steel, high manganese steel, tool steel, heat resistant steel, stainless steel, molten aluminum and its alloys. Melting copper, brass, cupric and bronze alloys, etc.

A brief introduction to a kind of ramming material, carbon ramming material.
