为满足用于冷锻的无表面缺陷线材需要量的增加，神户钢铁公司开发了表面缺陷深度＞０．０３ｍｍ的线材自动检测和清除新技术。采用该技术后线材在冷成形中不会因表面缺陷而产生裂纹。新开发的线材表面缺陷自动检测和清除装置的系统构成如下：在拉丝矫直机和拉模箱之间设有普通?
To meet the demand for non-surface-defect wires for cold forging, Kobe Steel has developed a new automatic wire rod inspection and removal technology with a surface defect depth of> 0.03mm. After adopting this technology, the wire will not crack due to surface defects during cold forming. The newly developed system for the automatic detection and removal of wire surface defects consists of the following: Between the drawing straightener and the die box there is an ordinary?
