Causes and Preventive Measures of Surface Pitting for High Surface Quality Steel Plate
Pages: 14-17
Year: Issue:  5
Journal: Wide and Heavy Plate

Keyword:  高表面质量钢板表面麻点预防措施;
Abstract: 针对某钢厂生产高表面质量中厚钢板表面麻点缺陷的特点,从板坯缺陷、加热制度、除鳞控制、轧辊维保、轧钢工艺等方面对其产生原因进行了分析和研究.认为钢板表面麻点是在多种因素的交互作用下产生的,与氧化铁皮的控制有直接关系,除鳞和轧制是关键工序.提出了降低钢板表面麻点产生几率的4项主要预防措施,通过现场实施,表面麻点缺陷数量得到大幅度减少.
