Design And Implementation Of Lubrication Control System In Hot Rolling Production Line

At present, metallurgical equipment for grease lubrication system has two technology dual-line concentrative lubricate system and single-line concentrative lubricate system, and manual lubrication is still used widely. These lubrication technology can not adapt to the upgrading of equipment, and often caused by lubricating the deficiency and excess. The new automatic-lubrication system developed in china, mostly are equipped an electric system on the traditional lubrication system, but the mechanical structure has not redesign too big change. Therefore, many defects of the traditional lubrication system are inevitable. In a hot rolling plant, the lubrication system of hydraulic device use the single-line or dual-line traditional lubricate system, some lubricate dot are lubricated excessly or absently because of the inconsequence of the structure. The system and technique of lubrication are quite behind the times; and some lubricate dot are at the covert position bring out check fault so difficult and waste the lubricating grease so seriously. To solve the above-mentioned problems, we must reconstruct the existing lubricate pipelines and achive lubrication automatic control in hot rolling production line.The primary content contains the design and reconstruct on the architecture of the hardware, the network communication of the lubrication control system about the mutual supervisor and operation. The central design are the hardware of control system, the HMI system, the communication system. According to the characteristic of the device lubricate system, we are deeply analysis and research the architecture and means of the system, such as gathering the signals, analysising the signals, controlling the outputs, safety protector etc, which are the links of the whole lubricate control system circuit, and are designed by separately. The system can carry out the automatic function of the whole process, which can transfer the oil from the pump to every lubrication dot, realize intelligent supervisory control, manage dynamically, save energy, and so on.Base on the prophasely research work, the new lubricate control system has installed and runs on the hot rolling production line, and the performance of the new system is very stable and excellent.
