Abstract：There are two important technical measures for producing high-quality medium plates and heavy plates,which are improving the quality of continuous casting slab core and eliminating the central segregation and central porosity.This paper proposed a liquid-core heavy reduction rolling process,it makes factitious crystallization nuclei to be formed at the final solidifying end of continuous casting slab,and central segregation and central porosity effectively are eliminated.
