Abstract

This invention is related to metallurgy field and in particular manufacturing method for complex deoxidizer that may be used for deoxidization and alloy steel to be employed in alloy steel. Improving known production method of aluminum forms the basis of this invention. Filling combination of furnace contains both additive materials mixed to other deoxidization process and temperature variations in melting along with technological arrangements. Initially the materials with high melting temperatures are filled into the furnace. In the method cited, residue products and silica or manganese or titanium or vanadium or rare earth metals and ferro (iron) alloys containing combinations of these are used as the materials with high melting temperatures. Mixing of salty additive is done during careful stirring of bath before pouring of liquid material into the furnace. However, they must be melted and heated at temperatures which is 100 to 1500C above liquid temperature in case addition of aluminum is involved. The materials with high melting temperatures are added to liquid bath together with the materials crushed down to size not higher than 20 mm under these crushing conditions. The liquid bath is heated to temperature not lower than 1000C with careful stirring of bath and then addition of salty additives. Additionally, the materials melted in melting furnaces at high melting temperatures are poured into pouring ladle filled with liquid aluminum, Afterward, they are melted by means of newly formed atmosphere or neutral gas burners.
