rimmed steel(【技】未经脱氧或未经充分脱氧的钢。钢在冶炼后期不加脱氧剂,钢水中氧含量较高,浇人钢锭模后,发生强烈的碳、氧反应,产生大量一氧化碳气泡,使钢水沸腾,故称沸腾钢。: In contrast to killed steels, the manufacture of rimmed steels take advantage of the chemical reactions which take place when a non-deoxidized steel is allowed to solidify. 与镇静钢相反,生产沸腾钢是利用了非脱氧钢凝固时产生的化学反应。)
rimmed steel ingot(【技】未完全脱氧的钢水注人钢锭模凝固形成的钢锭。因在凝固过程中逸出气体引起"沸腾"现象而得名。: Sheet steel products requiring good surface quality are made from rimmed steel ingots, like, for example, car bodies and 'tin, cans. 要求有良好表面质量的薄钢板产品,例如汽车车体和镀锡铁罐头盒等,都是用沸腾钢钢锭生产的。)
