钢材的冷加工就是钢材在室温下、不加热而进行轧制的一种加工方法。这是一种新式的、先进的钢材加工方法。这种方法同钢材的热加工——将钢材加热后进行辗制的加工方法——比较起来,有一系列的优点:(1)成品的尺寸准确一致;(2)成品的表面光滑优良;(3)成品的机械性能(强度、硬度、韧性等)提高;(4)操作过程简化又安全;(5)机器设备缩减。在成品质量方面,如果采用热加工,甚至在热加工以后再加以平整也不能达到采用冷加工所达到的质量标准。钢材的冷加工是在冷辗机上进行的,按照辗辊
Cold working steel is a method of rolling steel at room temperature without heating. This is a new, advanced steel processing method. This method is the same as the hot working of steel - the processing method of steel after heating and rolling - in comparison, there are a series of advantages: (1) the size of the finished product is exactly the same; (2) the surface of the finished product is smooth and excellent; (3) ) The mechanical properties (strength, hardness, toughness, etc.) of the finished product increase; (4) the operation is simplified and safe; and (5) the equipment is reduced. In the finished product quality, if the use of thermal processing, even after the thermal processing and then to be flat can not meet the quality standards achieved by the cold. Cold-rolled steel is carried out in the cold-rolled machine, according to roller
