Deoxy: bath or molten steel were to adding deoxidizer deoxygenation Hebei Deoxidants, deoxygenated product into the slag or into a gas discharge operation. Deoxidation: precipitation deoxidation, deoxidation diffusion, vacuum deoxidizing compound deoxidizer, precipitation deoxidation: the block deoxidizer directly into molten steel, a deoxidizing element in molten steel inside the steel reacts with oxygen to produce a deoxygenated product into the slag floating deoxy method. Advantages: deoxy more efficient, simple Deoxidants Shandong, Wuhan Deoxidants consuming short, alloy consume less, lower costs; Disadvantages: easy to remain in the steel deoxidation product will cause endogenous inclusions. [N], [O], [S] and other elements will increase the viscosity of the molten steel, [P], [Mn], [C], [Si] and other elements will reduce the viscosity of the molten steel; high temperature molten steel flow is good; Rather, overheating and high flow of molten steel is good; low inclusion content of the molten steel, the molten steel flow is good;
