In the production of steel, the electroslag melting process is used. The surface of the electroslag bath interacts with oxygen, which affects the quality of the resulting steel.
Therefore, in order to prevent this, carbon materials — carbon black, coke, etc. — are supplied to the surface of the bath. But at the same time, excess carburization of the metal occurs. But if you use our expanded graphite as protection, this will reliably protect the steel from contact with oxygen and at the same time it will not cause additional steel curing. Moreover, due to the heat-insulating properties of expanded graphite, much less (25-35%) of electricity is required for remelting. Which will significantly reduce costs. Graphite consumption is 0.7-1.5 kg per ton of steel.
