周期式轧管机是轧钢车间的主要生产工具之一,轧管机轧辊的表面质量直接影响无缝钢管产品的产量和质量。近年来为适应我国船舶工业和石油工业的发展需要,我厂部分产品要按照国际通用标准进行验收,钢管表面质量要求有所提高。前几年按照新标准验收钢管时,产品报废率上升,年停机修磨轧辊时间明显增加,车间生产工时利用降低,而且精整工段为修磨钢管表面缺陷经常投入劳动力进行突击,对某些批量产品,还需采用逐根挑选的方法来完成,这就延长产品生产周期,增加工人劳动强度,增加车间资金积压,为此迫使我们对钢管成品表面造成结疤的主要原因之一:轧辊表面粘钢的问题进行充分的研究。现将我们
The periodic mill is one of the main production tools in the rolling mill. The surface quality of the mill rolls directly affects the output and quality of seamless steel pipe products. In recent years to meet China’s shipbuilding industry and the needs of the development of the oil industry, some of our plant products in accordance with international standards for acceptance, the surface quality requirements of steel increased. A few years ago in accordance with the new standard acceptance of steel pipe, the product rejection rate increased, the annual downtime grind roll significantly increased, reduced production time workshop, and the finishing section to repair the surface defects of steel pipe often put labor assault on some batches Products, but also by the method of selection by the root to complete, which will extend the product cycle, increase labor intensity and increase the backlog of funds in the workshop, forcing us to cause scarring on the surface of the pipe products, one of the main reasons: roll surface sticky The steel problem is well studied. Now we
