DEOXIDIZER AND DESULFURIZER FOR REFINING MOLTEN STEEL, WITH IMPROVED EFFICIENCY OF DEOXIDATION AND DESULFURIZATION

摘要

The present invention is covered with a steel pipe is made by putting the pipes inside a predetermined width that is Tube Mill fine particles of aluminum, magnesium, calcium, calcium and silicon, iron consisting of a certain component in the foil iron deoxidation and desulfurization efficiency is improved steelmaking and Note STEEL deoxygenation relates to the desulfurizing agent.; To this end, the present invention is a weight%, aluminum (Al) 30 ~ 50%, a magnesium (Mg) 5 ~ 20%, calcium (Ca) 1 ~ 3%, calcium carbonate _{(CaCO 3) 5 ~ 20%} , silicon ( Si) 2 ~ 6%, and the balance of iron (the deoxidizing prepared in powder or particulate form as composed of Fe) - preparing a desulfurizing agent and; Deoxidation of the powder or particulate form the ready-box In the desulfurizing agent continuously on the pipe jogwangi and at the same time, deoxidation and desulfurization efficiency is improved steelmaking and state STEEL, characterized in that consisting of the steps of Tube Mill a steel pipe of a predetermined diameter in the jogwangi It provides a desulfurizing agent and a method-deoxidation.; Thus, the present invention maximizes the deoxidation efficiency can prevent the deoxidizer is in the coil state, or a pipe covered with a foil state iron reacts with the oxygen in the atmosphere is a deoxidizer because it can be introduced into the molten steel.
