Cut-To-Length Steel Coil Processing Line With Slurry Blasting Descaling Unit

摘要

A cut-to-length line for processing coiled sheet metal having a thickness of greater than 0.200 inches has an uncoiler, a descaler, and flattening machinery which may be a stretcher leveler or a temper mill. The line is operated in an advancement mode by (i) the advancing the sheet metal through the line; and (ii) descaling the sheet metal in the descaler. In one aspect, when a length of sheet metal to be stretch leveled is positioned in the stretcher leveler, the line may be operated in an idle mode by: (i) stopping the advancement of the sheet metal from the uncoiler through the descaler; (ii) stopping descaling of the sheet metal in the descaler; and (iii) stretch leveling the length of the sheet metal. When stretch leveling is complete, the line may be operated in the advancement mode.
