针对镀锌板边部镀层缺陷,提出改进措施:1对唇刃进行分体拆卸、打磨以及除锈清理、上下唇刃处的气流交汇位置调整、气刀刀唇开口度优化调整。2边部挡板机械传动装置改进调整。3边部挡板本体的重新设计。4唇刃气流交汇位置和刀唇开口度定期检查及唇刃定期拆卸清理形成制度化。这些措施实施后,厚镀层产品的边部增厚和边部结渣现象大幅度减少,改善后相关质量缺陷降低了95%。
Aiming at the flaw of coating on the edge of galvanized sheet, the improvement measures are put forward: 1, the split and grinding of the lip edge and the cleaning of rust removal are carried out; the airflow convergence position at upper and lower lip edge is adjusted; 2 edge baffle mechanical transmission to improve the adjustment. 3 edge baffle body redesign. 4 lip airflow intersection location and the lip of the lip regularly check and regular removal of the lip to clean up the formation of institutionalized. After the implementation of these measures, the thickness of the edge of thick-plated products and slagging significantly reduced, the quality-related defects improved by 95%.
