轧制能耗是标志轧钢生产状况的一个重要技术指标。它是制订轧制规程,确定轧机负荷的实际有用的数据。轧制能耗曲线是直接由生产过程中实际计算而绘制出来的,所得结果切合实际,比理论计算较为精确。同时,确定轧制能耗较实测轧制压力的方法简单,现场也易于实现。尤其轧制非简单断面轧材时,常常遇到一个复杂的问题:轧件与轧辊的接触面积和轧制压力计算十分复杂,现无可靠的理论计算公式,只好采用近似的或经验公式来进行计 Rolling energy consumption is an important technical indicator of the status of rolled steel production. It is actually useful data for setting the rolling schedule and determining the mill load. The rolling energy consumption curve is directly drawn from the actual calculation in the production process. The results obtained are more realistic and more precise than the theoretical calculation. At the same time, the method of determining the rolling energy consumption compared with the measured rolling pressure is simple and the scene is easy to realize. In particular, rolling non-simple cross-section rolling often encountered a complex problem: rolling contact with the roll and the contact area and rolling pressure calculation is very complicated, there is no reliable theoretical formula, had to use approximate or empirical formula to meter
