Description

一种钢丝热镀锌后的抹拭方法
技术领域
本发明属于热镀锌领域,具体涉及一种抹拭掉钢丝热镀锌后钢丝表面粘附的锌液的方法。
背景技术
在钢丝表面镀上锌层是目前最有效和最常用的防止钢丝腐蚀的方法之一,常用的镀锌工艺包括热镀锌,钢丝经热镀锌从锌液出来后,一般要通过抹拭将钢丝表面粘附的锌液抹掉,以抹平镀层。传统的方法是将钢丝经过混有油的木炭层,抹拭掉锌液,但这种方法会产生大量的油烟,影响车间环境,且容易产油垢。为解决上述问题,专利201010503074.9公开了一种钢丝镀锌后的抹拭方法,它采用混有水的木炭层抹拭钢丝上锌液的方法,但该方法存在的问题是,高温下的锌与水容易反应生成氧化锌和氢气,反而增加了钢丝表面锌层的消耗,使镀层的厚度变薄。
发明内容
本发明的目的解决现有钢丝热镀锌后抹拭锌液时存在污染大、锌镀层消耗大的问题,提供一种无污染、减轻消耗的抹拭方法。
本发明实现上述目的所采用的技术方案如下:
一种钢丝热镀锌后的抹拭方法,包括在出锌锅的钢丝周围的锌液上铺设有抹拭层,所述抹拭层由上、中、下三层组成,其中,抹拭层的上层和下层均为3~5厘米厚的木炭层,中层为7~9厘米厚的石英砂层。
进一步,所述石英砂层由颗粒大小为0.1~0.5mm的石英砂组成。
进一步,钢丝以20~30m/min的速度通过抹拭层。
有益效果:本发明采用复合夹心层替代传统的油木炭或水木炭层,无需对原生产线进行改装,无油雾产生,对车间环境无污染,钢丝表面镀层厚度均匀、光泽度高,镀层表面不沾有黑渣或炭末。
具体实施方式
以下结合实施例对本发明做进一步详细说明。
实施例1
在锌锅的钢丝周围的锌液上铺设有20cm×30cm的抹拭层,抹拭层由上至下分别为3厘米厚的木炭层、7厘米厚的石英砂层(0.1~0.5mm的石英砂)和5厘米厚的木炭层组成。钢丝以25m/min的速度通过抹拭层。
实施例2
在锌锅的钢丝周围的锌液上铺设有15cm×30cm的抹拭层,抹拭层由上至下分别为5厘米厚的木炭层、9厘米厚的石英砂层(0.1~0.5mm的石英砂)和3厘米厚的木炭层组成。钢丝以30m/min的速度通过抹拭层。
实施例3
在锌锅的钢丝周围的锌液上铺设有20cm×30cm的抹拭层,抹拭层由上至下分别为3厘米厚的木炭层、8厘米厚的石英砂层(0.1~0.5mm的石英砂)和4厘米厚的木炭层组成。钢丝以20m/min的速度通过抹拭层。
