摘要
分析ML08AL冷镦钢钢丝半成品及1/3冷镦试样形貌,指出冷镦开裂是由连铸坯角部裂纹和轧制过程中轧件划伤造成的,通过优化浇铸工艺,加强轧辊和导卫的检查,在集卷、打包、吊装、运输、倒运过程中采取保护措施,可有效提高冷镦合格率。
To analyze the appearance of ML08AL semi - finished cold heading wire and cold heading piece with 1/3, it is pointed out that cold heading crazing is due to comer crackle of continuous cast billet and rolling piece scratching during rolling. The cold heading pass rate can be raised by optimizing casting process, strengthening inspection of roller and guider, taking protection measure in the course of coil collecting, packing, hoisting, transporting and back carrying.
