REALIGNMENT METHOD FOR SPRAY NOZZLES OF COOLING WATER ON CONTINUOUS CASTING PROCESS

摘要

The present invention is in the cast surface water to cool while playing the slab continuous casting relates to the cooling water spray nozzle disposed in continuous casting method for arranging the nozzle for spraying, the cast playing the transverse direction at a flow rate of the first injection nozzle and the second injection nozzles are adjacent to each other in one column of the plurality of heat injection nozzle installed and measuring a first jetting nozzle and the second jetting nozzle and the first area of overlap portion where the non-aqueous coolant is injected in the overlap each other by a second spray nozzle of a spray nozzle flow rate ratio as a variable measured by the (L2), and calculating a constant distance (D) that indicates, the method comprising: calculating a position (L2) overlapping the non-aqueous portion to a constant distance (D) as calculated by the parameter, the non-aqueous portion was determined in the overlap to the position (L2) as a variable, the decision leading position movement value (R) indicating the non-aqueous portion overlapping position (L2) generated by the first row and second column of the jetting nozzles are adjacent to each other and a plurality of heat injection nozzle, wherein In the continuous casting provides a coolant injection nozzle disposed method including the step of relocating the first row and second column injection nozzle according to the leading position movement value (R) was determined. ;
