Title:
PROCESS OF MANUFACTURE OF MOLTEN METAL
Document Type and Number:
Japanese Patent JP2016090139
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a process of manufacture of molten metal capable of controlling a turning of an electric furnace of which furnace body can be turned in respect to electrodes in view of a spatial non-uniformity of molten state of metallic material in the furnace body.SOLUTION: This invention controls a turning of furnace body by a furnace body turning part 30 on the basis of control parameters including at least one of a temperature of refrigerant measured by a temperature measuring part 51 and a position of an electrode 25 measured by an electrode position measuring part 43b under an arrangement of an electric furnace: comprising an electrode 25 for melting metallic material by an arc discharge while keeping a distance between it and the metallic material in a furnace body constant; a furnace turning part 30 capable of turning the furnace body and changing a relative position of the furnace body in respect to the electrode; a cooling part 50 arranged at a wall surface of the furnace body, supplying refrigerant to cool the furnace body; a temperature measuring part 51 for measuring temperature of the refrigerant at a plurality of positions at the wall surface of the furnace body; and an electrode position measuring part 43b for measuring position of the electrode 25 along an inserting direction into the furnace body.SELECTED DRAWING: Figure 2
