A SLAG COMPOSITION FOR DEOXIDATION OF MOLTEN STEEL

摘要

The present invention relates to a composition used for the deoxidation treatment of molten steel in order to improve the cleanliness of molten steel, in the preparation of slag used for the deoxidation of molten steel in the manufacture of clean steel, aluminum or a strong oxidizing reducing agent By adding carbon to the mixture of magnesium and limestone in a weight ratio of 20% or less to form a slag preparation agent, it contributes to the direct deoxidation by utilizing the deoxidation capacity of carbon itself, and after deoxidation, the gas is agitated so that the gas is stirred. By allowing uniform deoxidation of molten steel by slag, it is possible not only to manufacture high clean steel but also to improve the quality of molten steel.
