摘要：
In view of the characteristics of drastic changes in shell thickness and temperature field of continuous casting billets in each sector, the variation law of limit reduction of billets in different reduction intervals was studied systematically. Taking A36 steel continuous casting billets as the research object, a three-dimensional thermodynamic coupling model including billet, casting roller and the multi-body contact between them was established. Under the premise of ensuring the processing quality, the limit reduction, reduction zones and reduction distributions of the casting billets were studied systematically. The results show that the limit reduction of A36 steel billets from the first section of bending section to the tenth section of horizontal section is as 3.87~6.96 mm. The suitable reduction sections at the end of solidification are the 8th～10th sections, and it is suitable to distribute the reduction evenly in these reduction sections. © 2022 China Mechanical Engineering Magazine Office.
