冶炼过程中各种工艺参数的稳定,对于生产的正常进行和维持良好的技术经济指标具有十分重要的意义。有色冶炼过程中要求控制的主要工艺参数有:温度、压力、流量、料位、气体与液体的成分和性质(酸度、浓度、密度等)以及物料重量等。为了叙述方便,按被控参数分类选择一些比较典型的自动调节系统进行介绍。 Smelting process in a variety of process parameters of stability, for the normal production and maintenance of good technical and economic indicators of great significance. Non-ferrous smelting process requires control of the main process parameters are: temperature, pressure, flow, level, gas and liquid composition and nature (acidity, concentration, density, etc.) and the weight of the material. In order to describe the convenience, according to the controlled parameters to select some of the more typical automatic adjustment system introduced.
