Abstract
PURPOSE: To mass-produce titled sheet steels excellent in preventing the occurrence of bubbling defect by forming an Al hot dipped sheet steel to an open coil, then subjecting the same to two stage of heat treatment.
CONSTITUTION: After an Al hot dipped steel strip is formed into an open coil, it is subjected to the 1st stage heat treatment for heating the same for a required time at temperature ≤500°C, whereby the growth of an intermetallic compound of Al- Fe-Si is suppressed. In succession to this heat treatment, it is subjected to the 2nd stage heat treatment of heating the same for a required time at temperature ≥510°C. After the execution of the 1st stage heat treatment, no intermetallic compounds grow despite the execution of the 2nd stage heat treatment, and the excess hydrogen gas in the sheet steel and plating layer is removed. By the above-mentioned two stage heat treatments, the Al hot dipped sheet steels excellent in preventing the occurrence of bubbling defects and in adhesion strength of enamel coating are massproduced.
