摘要
分析了含镍钢氧化铁皮难去除的原因,从减少含镍钢氧化铁皮咬合层生成入手,采取"在钢坯表面喷涂高温防护涂层"技术,改善含镍钢氧化铁皮的除鳞效果。解决了轧钢工序含镍钢除鳞不净问题造成的钢材表面麻坑、夹杂等明显缺陷。节省了修磨费用,缩短了交货周期,提高了金属收得率,降低了含镍钢的生产成本。
The reason for scale on nickel - bearing steel being difficult to remove is analyzed. To weaken the formation of scaie occlusal layer on nickel - bearing steel, the technique of " spraying high - temperature pro-tection coating on steel billet" is adopted and then the scale removal effect improved. The obvious defects on steel surface such as pockmark and inclusion are eliminated, the fixing and grinding cost decreased, the deliv-ery cycle shortened, the metal yield increased, the production cost of nickel - bearing steel decreased.
