Abstract
PURPOSE: To obtain steel plate of excellent processability by the procedure in which hot rolled steel plate coil wound up at high temperature is covered with a heat insulating cover and then the outside circumference of the coil is cooled at a definite cooling rate unitl a definite temperature is reached.
CONSTITUTION: The hot rolled steel plate coil wound up at a temperature above 600°C is covered with a heat insulating cover quickly in a temperature range of more than 600°C. The heat insulating cover consists of the ceiling 1, the outer plate 2, and insulating material 3, and hook 4, and the supporting bar 5 for example. The temperature of the outside circumference of the steel plate coil covered with the heat insulating cover is cooled at an average cooling rate of less than 5°C/min unitl the temperature (ambient temperature-250°C) is reached. This method enables one to obtain hot rolled steel plate of an uniform mechanical strength and cxcellent processability and also to obtain cold rolled steel plate of excellent processability by subjecting it to cold rolling and then annealing.
