引言武钢矿源含铜,目前钢中含铜0.2％左右。多年以来,大量试验研究表明:铜能显著提高钢材的耐腐蚀性能,特别是耐大气腐蚀,同时,对钢材的强度和硬度也略有增加。目前,武钢含铜低合金钢已广泛地应用在桥墚、铁路,船舶、车辆、锅炉、化工容器以及国防建设等方面,有力地支援了社会主义革命和建设。但是,由于武钢一米七轧机的兴建,人们越来越关心:铜对硅钢片的电磁性能有什么影响?含铜钢能不能制成高牌号
Introduction Wuhan Iron and steel source copper, the current copper content of about 0.2% copper. Over the years, a large number of experimental studies have shown that: copper can significantly improve the corrosion resistance of steel, especially atmospheric corrosion resistance, while the strength and hardness of steel also increased slightly. At present, Wuhan Iron and Steel Co., Ltd. low-alloy steel containing copper has been widely used in the bridge, railways, ships, vehicles, boilers, chemical containers and national defense construction, etc., effectively supporting the socialist revolution and construction. However, due to the construction of Wuhan No.17 Mill, people are more and more concerned about the influence of copper on the electromagnetic properties of silicon steel sheet. Can the high grade of copper-containing steel be made?
