由上钢二厂负责试制的新产品刀口钢丝,在上海市经委主持下,于1987年12月18日在苏州市通过了技术鉴定。刀口钢丝是医疗器械行业架盘药物天平关键材料之一,其断面是由半圆形和等腰三角形组合而成。过去医疗器械行业采用人工切削而成,现在上钢二厂采用冷加工直接成型工艺制造。此产品具有简化加工工序、节约钢材、提高加工表面质量等特点。已在国内医疗器械行业得到了推广应用。刀口钢丝试制成功,为我国冶金工业又填补了一项品种空白。
The new product knife wire produced by Shanghai No. 2 Steel Works was under the auspices of the Shanghai Municipal Economic Commission and passed a technical appraisal in Suzhou on December 18, 1987. Knife wire is one of the key materials for medical scales in the medical device industry. Its cross section is composed of semicircular and isosceles triangles. In the past, the medical device industry used artificial cutting, and now Shanghai Steel No. 2 Plant uses a cold forming direct molding process. This product has the characteristics of simplifying the processing procedure, saving steel materials, and improving the quality of the processing surface. Has been promoted in the domestic medical device industry. Successful trial production of knife-edge steel has filled China’s metallurgical industry with a variety of blanks.
