Abstract
PURPOSE: To economize electric power consumption by charging the compds. prepd. by compounding required side materials, auxiliary raw materials and a slag forming agent to a main raw material, which consists of chromite ore, ferrochromium silicide and ferronickel silicide, continuously into a high frequency induction electric furnace and producing a titled steel ingot.
CONSTITUTION: A main raw material 1 consisting of chromite ore, and ferrochromium silicide and ferronickel silicide as reducing agents, a secondary raw material 2, an auxiliary raw material 3 such as nickel oxide, a slag forming agent 4 such as an alumina base raw material and titanium-contg. iron sand are charged in a conical ball mill 5. Here, these are ground and mixed, and the mixture is charged continuously into a high frequency induction electric furnace 9 lined with magnesia through an elevator 6, a conveyor 7 and a chute 8, whereby the mixture is melted. During melting, the molten metal is controlled by discharging slag, and this is made into an ingot, whereby a nickel chromium stainless steel ingot is obtained.
