研究了低碳钢钢锭红送裂纹的形成机理－ 分析并计算了钢锭红送及装炉再加热全过程的温度场和应力场的变化规律，测定钢锭的组织结构和高温强度、塑性，与内应力的变化相比较，分析其开裂的可能性和开裂的时机，得出了低碳钢钢锭红送裂纹的形成机理－ 为生产中防止红送裂纹提供了理论依据－
The formation mechanism of red crack in low carbon steel ingot was studied. The change rule of temperature field and stress field in the whole process of red ingot feeding and reheating of ingot were analyzed and calculated. The microstructure and high temperature strength, ductility, Compared with the change of stress, the possibility of cracking and the timing of cracking were analyzed. The formation mechanism of red crack in low carbon steel ingot was obtained - providing a theoretical basis for preventing red crack in production -
