Abstract: Aiming at the problems of low lubrication points , high lubrication pressure , poor lubrication reliabili- ty ,and poor quality in the traditional two-line dry oil lubrication system of the stepping cooling bed in steel production enterprises, the new carrier type intelligent dry oil lubrication system and method were put forward to meet the requirements of the stepping cooling bed. Firstly , the composition and control principle of the carrier-type intelligent dry oil lubrication system were analyzed,and the hardware control system of the carrier-type intelligent dry oil lubrication system was developed. Then , the traditional two-line dry oil lubrication system was reformed and upgraded , the industrial control software management system of lubrication system was constructed, and the monitoring mode of point-by-point oil supply and point-by-point detection was adopted to ensure that each lubrication point had sufficient oil supply pressure. Finally,by testing and optimizing the parameters of the stepping cooling bed lubrication system of the 1. 1 million tons cooling bed rolling process ,the pressure of the lubrication system was reduced from 25 MPa before the improvement to 15 MPa, and the lubrication quality was still guaranteed. The results showed that:(1)The dedicated communication line of the control cabinet to the field was simplified by the use of carrier communication technology; (2) By increasing the closed-loop lubrication monitoring system and the number of lubrication points ,based on the point-by-point oil monitoring control and other measures to reduce the lubrication pressure on 10 MPa, the lubrication system energy consumption was effectively reduced; (3)Better economic and social benefits had been achieved by system testing and production inspection on the stepping cooling bed production line.
