摘要
中厚板轧机支承辊是轧辊产品中尺寸大、重量大、制造难度大的品种,技术含量很高。现代支承辊制造技术中,锭型设计运用了计算机数值模拟辅助设计,冶炼技术采用双真空,锻造工序普遍运用KD法(上下宽V型砧大压下量锻造法),在热处理工艺方面也有许多独特技术。
The medium and heavy mill backup roll is a roll product with large size, heavy weight, difficult to manufacture and high technical content. In modem manufacturing technology of the backup roll, com- puter numerical simulation aided design is applied to ingot shape design. Smelting technique of double vacuum is adopted. Forging process is utilized generally the method of KD （under the wide type V anvil large forging ratio method）. There are many unique technologies in the heat treatment process.
