Metallurgy ladle refining's introduction

Refining outside the furnace divides the traditional steelmaking into two steps. The first step is called primary refining, which is the melting, dephosphorization, decarburization and main alloying of the furnace charge in an oxidizing atmosphere; The second step is called refining. Deoxidation, desulfurization, inclusion removal, inclusion denaturation, fine adjustment of composition, control of molten steel temperature, etc. are carried out in vacuum, inert atmosphere or controllable atmosphere.
