辊道窑磁砖生产线PLC控制

辊道窑磁转生产线对控制设备的可靠性要求极高，但传统继电器控制系统的故障率高，寿命短，无法满足现代生产的需求，因此，用可邓控制器设计控制器，是近年来发展的趋势，根据生产线的动作机理和逻辑关系，利用真表及逻辑分析方法，分别设计生产线上的翻坯、窑前和窑后的ＰＬＣ控制器，经现场运行，证明性能稳定可靠，它对新型窑炉设计和旧窑炉改造都具有应用价值。

Control of Programmable Controller (PLC) on the Tile Production Line of Roll Way Kiln

High reliable control equipment is required by a tile production line of roll way kiln. However, the conventional relay control system failed to meet the demand of modern production due to its high error rate and short life. To control by programmable controller is the trend. In the light of action mechanism and logic relation of production line, programmable controllers (PLC) are designed respectively for turning frame, kiln front and kiln latter on the production line by using true value chart and logical analysis. They are proved by on spot operation to be stable and reliable. This kind of controllers are of practical value for designing new kiln and modifying old one. The charts of control principle and control ladder are given finally.
