METHOD FOR ADJUSTING DEGREE OF TAPER OF FACE PLATE MATERIAL WITH NARROW WIDTH BEING ADJUSTABLE BETWEEN FACE PLATE MATERIAL WITH WIDE WIDTH OF LIQUID COOLING TYPE CASTING MOLD OF PLATE MATERIAL FORM FOR MANUFAC- TURING CONTINUOUS CAST MATERIAL WITH STEEL PIECE SHAPE FROM MOLTEN STEEL

摘要

PURPOSE: To prevent the occurrence of hindrance in a solidified shell by determining the specific temperatures of respective narrow-face and broad-face plate materials from the temperatures in the coolant outlets of the respective plate materials, comparing these temperatures and regulating the degrees of the tapers of narrow-face plate materials when there is a difference. CONSTITUTION: The temperatures of the coolant in the coolant outlet of the liquid-cooled narrow-face and broad-face plate materials 1 to 4 are measured. The specific temperatures of the respective plate materials 1 to 4 are then determined from the measured temperatures and the specific temperatures of the opposing plate materials 1 to 4 are compared. Further, the specific temperatures are compared with the specific temperatures of the adjacent plate materials and if there is the difference in the specific temperature values, the regulation values corresponding to a magnitude of the difference are supplied to drive assembles 15 and 16 of the narrow-face plate materials having the lower specific temperatures, by which the degrees of the tapers are regulated.
