METHOD FOR CENTERNING TOP ZONE IN CONTINUOUS CASTING INSTALLATION

摘要

PURPOSE:To execute easily and exactly centering by providing a tentative mold having the same reference planes as the reference planes of an actual mold body of a continuous casting installation onto a centering check stand and centering the single body of the top zone in conformity therewith. CONSTITUTION:The top zone 2 is supported to a trunnion receiving part 3 of the centering check stand 1 for the mold top zone. The tentative mold 5 having the same reference planes (a)-(c) as the reference planes of the mold body is then installed on the stand 1. Said mold is positioned perpendicularly to the discharge direction by a guide pin 7 in the same manner as for the mold body and is pressed to the plane (a) by an attracting metal 8. A stationary guide plate 9 of the mold 5 and a roll 10 thereof contact with each other and the zone 2 inclines at exactly the same degree as the inclination on the actual machine. The mold 5 has reference rolls 6, 17 in the positions corresponding respectively to the inside surface of the mold copper plate and the roll adjacent to the lowermost roll 19' of the zone 2. An R gage 12 is fixed to the surfaces of the rolls 6, 17 by an R gage holder 18 and a roll 19, a cooling grid 20, etc. are adjusted to comply with the gage plane in the stage of centering the roll, the cooling grid, etc.
