取鍋予熱装置および取鍋予熱方法
Document Type and Number:
Japanese Patent JP6733887
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a pan preheater capable of further reducing an energy loss by eliminating a variation in heating of a pan inner wall.SOLUTION: A pan preheater having a pan 1 having an opening part of becoming a pouring port of molten metal in an upper part and a sealing cover 2 for sealing the pan 1 by blocking up the opening part, comprises a central electrode 5 inserted into the center of the pan 1 by penetrating through the sealed cover 2, a plate electrode 6 provided in parallel to a pan-1 bottom surface on the tip of the central electrode 5 and extending in at least two directions toward a pan-1 inner wall, at least two electrode 3 and electrode 4 inserted into a position corresponding to the plate electrode 6 of the pan 1 by penetrating through the sealed cover 2, and heats the pan-1 inside by using radiation heat of a generated arc by generating the arc between the electrode 3, the electrode 4 and the plate electrode 6.SELECTED DRAWING: Figure 1
