Anhydrous ramming mass for submerged arc furnaces

The Submerged Arc Furnace (SAF) uses arc and resistance heating to convert electrical energy into thermal energy, reducing metal oxides in ores within a closed or semi-closed environment. It is a core piece of equipment in the metallurgical industry, essential for high-temperature reduction smelting processes, and is primarily used to produce ferroalloys (such as ferrosilicon, ferromanganese, and ferrochrome), calcium carbide (CaC₂), yellow phosphorus, and other key products.

Refractory castables for submerged arc furnaces

Refractory castables for submerged arc furnaces are unshaped refractory materials used as linings inside these furnaces—primarily designed for smelting ferroalloys, calcium carbide, and other similar materials. After being mixed with water or a binding agent, they are poured and shaped to form a durable protective layer. These materials must withstand severe erosion from high-temperature molten metals, mechanical abrasion, and thermal shock, while also exhibiting excellent resistance to corrosion, superior thermal stability, and robust high-temperature strength. As a result, they are ideal for safeguarding various sections of the furnace lining. Proper selection of furnace castables combined with standardized construction practices can significantly reduce the rate of lining damage, minimize the frequency of furnace shutdowns for maintenance, and ensure the efficient and safe operation of the submerged arc furnace.
