Abstract
Abstract This invention relates to an improved mold for continuous casting process, wherein a metallic material having cooling capacity of 0.1 to 0.7 [cal/(cm2 . DEG C . 2ROOT sec)] and thermal conductivity ( lambda ) of 0.3 to 0.7 [cal/(cm.sec. DEG C)] is used as a mold whereby surface checkings such as tortoise shell patterns or cracks are prevented from occuring.
