在锻压加工中,润滑剂的重要作用已被越来越多的锻造工作者所认识。在使用润滑剂时,由于锻造工艺不同,锻造温度差异,加热时间长短等因素,对润滑剂的要求也有所不同,所以选用一种合适的润滑剂是锻造工艺和生产的一个较为重要的问题。现在一般根据锻造时的温度将锻造工艺分成冷锻(室温～200℃),温锻(200～800℃)及热锻(800～1200℃)三大类。通常润滑剂也可按这样的温度范围及工艺特点加以划分和选用。这是一个简便而有效的方法。
In the forging process, the important role of lubricant has been recognized by more and more forging workers. In the use of lubricants, due to different forging process, forging temperature difference, the length of heating time and other factors, the requirements of lubricants are also different, so the choice of a suitable lubricant forging process and production of a more important issue. Now generally according to the forging temperature will be divided into forging cold forging (room temperature ~ 200 ℃), warm forging (200 ~ 800 ℃) and hot forging (800 ~ 1200 ℃) three categories. Lubricants can also be divided by the temperature range and process characteristics and selection. This is a simple and effective method.
