热镀锌线锌锅沉没辊刮刀装置的开发与应用

Development and application of the sink roll scraper device for hot dip galvanizing line

沉没辊刮刀装置是连续热镀锌生产线中最重要的辅助设备之一,它的作用是将沉没辊上附着物清除干净使其表面在作业周期内保持一定的光洁度,不结渣结瘤影响带钢表面质量。针对沉没辊刮刀装置工况条件恶劣,导致机械磨损加剧、腐蚀严重且寿命短的问题,酒钢集团镀锌线技术人员经过两年的技术革新,开发出来一种安全可靠、使用寿命长的可在线有效刮除锌锅沉没辊黏渣的刮刀装置,解决了丝杠卡阻变形、螺母磨损严重、润滑不良以及与沉没辊辊面压靠力不稳定的技术问题。应用效果良好,降低了生产机组的综合成本,镀锌板的表面质量得到了提高。

Sink roll scraper device is one of the most important auxiliary equipment of continuous hot galvanizing production line, it is used to clean up the attachment on the roll and make the roll ‘s surface certain smoothness in operation period, because nodulation without slag could effects the quality of steel＇s surface. Sink roll scraper device is always in poor working conditions, which made the device wear more, corrode more and have a shorter life. The people of Jiuquan Steel Group galvanizing line technical personnel developed a safe and reliable scraper device after two years of long service technological innovation which have a longer life and could effectively get rid of slag that comes from zinc pot sinking.Meanwhile, The device settle down a series of problems such as the deformation of screw clamping, nut wearing, poor lubrication and a problem that sink roll surface pressure moved by force is not stable. The application of the device is prefect, and the comprehensive cost of the production unit is reduced. The surface quality of galvanized sheet is well improved.
