钢包精炼锭锻制冷辊坯的研究

Research for Cold Roll Blank Forged by Ladle Refining Ingot

采用钢包精炼炉冶炼、宽平砧大压下量锻造、“正火 +球化 +扩氢”的热处理工艺 ,成功制造了冷辊坯 ,合格率达 90 .5 %。

Based on ladle refining, wide flat anvil forge with great forging ratio, heat treatment process of 'normalizing+spheroidizing+diffusion hydrogen',the cold roll blank has been forged succesfully,and the percent of pass is up to 90.5%.
