钢水连续浇铸是世界上近二十年发展起来的先进技术,它的应用在我国还处于起步阶段。液压在连铸设备控制中起着主导作用,它控制了连铸主体设备的近百台油缸的操作,起着引锭,拉、压坯,停电事故处理等作用。就液压系统本身来看,它采用了集成、叠加,插装技术相融合而构成的换向、差动、同步、压力变换等回路,并采用了压力比例控制技术,油温、液位自动控制及远距离压力检测技术。下面,就液压如何控制主体设备进行工作以及该系统中部分有特色的控制回路做粗略的介绍和分析。连铸主体设备的液压控制
Continuous casting of molten steel is an advanced technology developed in the past 20 years in the world and its application is still in its infancy in our country. Hydraulic pressure plays a leading role in the control of continuous casting equipment. It controls the operation of nearly one cylinder of continuous casting main equipment, plays the role of lead ingot, pulling, compaction, power failure handling and so on. The hydraulic system itself, it uses a combination of integration, stacking, insertion technology consisting of commutation, differential, synchronization, pressure conversion circuit, and the use of pressure proportional control technology, automatic control of oil temperature, liquid level And long-distance pressure detection technology. Here, on how to control the main hydraulic equipment and the work of the system part of the characteristics of the control loop to do a rough introduction and analysis. Hydraulic control of continuous casting main equipment
