LF Series Ladle Refining Furnace

ADD INQUIRY

· Application

The furnace can be used in refining molten steel for electric arc furnace and convertor with the functions of arc heating, argon churning, temperature measurement and sampling and alloy melting. It is an ideal system for producing special steel such as high-quality carbon steel, alloys structural steel, bearing steel, tool steel and stainless steel and meets the need for continuous cast and continuous rolling.

· Structure Features

Customers can specify furnace model or the combined model based on the type of steel or smelting processes.
