Abstract

PURPOSE: To provide quenched steel plate with flatness and to eliminate reheating process thereof, levelers are incorporated just upstream and down stream of cooling device.
CONSTITUTION: A steel plate advances from the rolling machine 1 at a temperature higher than A3 modification point and is adjusted in its flatness to a some degree by the hot leveler 3. The plate is admitted into the cooling device 3 to be cooled by sprayed water or other usual means. The cooler needs no such high pressure device as roller pintch or pressure pintch. The quenching by the cooler 3 is controlled so that the temperature will not decrease too low below the modification complete temperature, and the plate is sent to the leveler 4 to be corrected in its flatness. Next, the plate advances to be reheated again for tempering process.
