轧钢是冶金企业的一个重要环节。热轧成型之前,坯料一般都要加热,这一工艺环节往往要花费很大的能量,因而节约能耗有相当大的潜力。目前中厚板材的生产越来越广泛地采用控制轧制新技术,使普通钢和低合金钢的板材获得很高的机械性能、低温冲击韧性和良好的焊接性能。这样生产出来的板材不需要进行常化热处理,这不仅节省了能量,而且可以使板材性能超过常化后的板材性能。但是控制轧制这一技术总有一
Rolling is an important part of metallurgical enterprises. Prior to hot forming, the billets are generally heated, which often consume a great deal of energy and thus have considerable potential for energy savings. At present, the production of medium and thick sheet metal is more and more widely used new technology of controlled rolling, so that the ordinary and low alloy steel sheet to obtain high mechanical properties, low temperature impact toughness and good welding performance. The panels thus produced do not require a heat treatment of normalization, which not only saves energy but also allows the performance of the panel to exceed the normalized panel properties. But there is always one technique for controlling rolling
