fine drawing

Surface bright band of drawn steel wire appears during drawing.

拉拔钢丝表层出现白亮带 ,通过对拉拔钢丝的能谱成分、高低倍组织及热处理试验试样的组织分析 ,结果表明拉拔钢丝表层白亮带组织是马氏体 ,该马氏体的形成与拉丝模孔型超差、润滑条件不良等引起的瞬间高温有关 ,不属于盘条质量问

It is pointed out that the fine stainless steel wire produced by melting drawing can only be used to some realms having not high requirements because of its section being shaped;the fine stainless steel wires produced by clustered drawing method have not uniform shape,uniformity and precision are worse,and the length of the fine wire is limited;the single wire drawing is.

介绍不锈钢极细丝的生产方法、热处理工艺及生产中存在的问题,指出采用熔抽法制成的不锈极细丝,横截面多为异形,只能用于一些要求不高的领域;集束拉拔法生产的不锈极细丝形状不一致,均匀性和精度较差,并对极细丝长度也有一定限制;单丝拉拔法是高档次、高精度不锈极细丝的主要生产方法,国内企业应加紧0。
