成材率是模具钢用轧制锭生产中需要考虑的重要因素。对钢厂原有3.0 t模具钢用轧制锭进行重新设计与优化,并使用Procast模拟软件对其凝固过程的温度场、全凝时间和内部缺陷进行了模拟计算,旨在保证质量的前提下提高成材率。研究结果表明,新设计3.1 t钢锭的全凝时间为1.78 h,原有3.0 t锭型全凝时间为2.03 h,全凝时间缩短了12.32%,钢锭内部质量良好。在涵盖现有轧制规格和不增加轧制道次的前提下,锭型数量由5个减少到4个。采用40 t EAF-LF-VD模铸工艺路线对新设计的3.1 t钢锭进行小批量生产,初轧后满足GB/T4162-2008 B级探伤规格。锭型优化后的的平均成材率为83.76%,原锭型的平均成材率为78.71%,平均成材率比原来提高5.05%。
Yield rate is an important factor to be considered in the production of rolled ingot for die steel. The redesigns and optimizes of the original 3.0 t die steel ingot used in a steel plant are carried out by using Procast simulation software to simulate the temperature field, total setting time and internal defects during the solidification process, aiming to improve the yield rate under the premise of ensuring quality. The results showed that the total solidification time of new designed 3.1 t ingot is 1.78 h, and that of original 3.0 t ingot is 2.03 h, the total solidification time is reduced by 12.32%, and the ingot internal quality is good. On the premise of covering the existing rolling specifications and without increasing the rolling passes, the number of ingots is reduced from 5 to 4. The newly designed 3.1 t steel ingot is produced in small batch by using 40 t EAF-LF-VD die casting process. After initial rolling, it qualified the GB /T4162-2008 grade B flaw detection specification. The average yield rate of the optimized ingot is 83.76%, the average yield rate of the original ingot is 78.71%, and the average yield rate is 5.05% higher than the original.
