Steel pusher control system for steel rolling heating furnace

Abstract

The invention discloses a steel pusher control system for a steel rolling heating furnace. The steel pusher control system comprises two displacement detection units used for measuring the displacement values of a first steel pusher and a second steel pusher in the steel pushing process in real time, an initial position proximity switch, a middle position proximity switch, a termination position proximity switch and a main control unit. The initial position proximity switch is used for calibrating the initial positions of the first steel pusher and the second steel pusher. The middle position proximity switch is used for calibrating the middle position of the first steel pusher and the second steel pusher. The termination position proximity switch is used for calibrating the termination positions of the first steel pusher and the second steel pusher. The main control unit is used for calling an internal clock interrupt processing program and a deviation compensation algorithm to obtain a deviation compensation correction amount through calculation and controlling an oil cylinder driving unit to dynamically correct the deviation so as to realize synchronization. According to the steel pusher control system for the steel rolling heating furnace, synchronous operation of the two independent steel pushers can be achieved, the automation degree and the working efficiency of equipment operation can be greatly improved, it is guaranteed that the system meets the requirement of a company for improving the heat transfer rate, and the purposes of reducing cost and improving efficiency are achieved.

Description

technical field [0001] The invention relates to the technical field of iron and steel production, in particular to a steel pusher control system for a steel rolling heating furnace. Background technique [0002] The company's steel rolling heating furnace is hot-feeding and horizontally moving pusher is an important production equipment in the continuous casting slab hot-feeding and hot-charging process. Since it was put into production, the failure rate has remained high, seriously affecting the hot delivery rate of continuous casting slabs. After the equipment personnel and technicians inspected the online equipment maintenance and process execution, they found that the main reason was that the two horizontal steel pushing machines were completely independent equipment. Due to the influence of factors such as pressure difference and different friction coefficients of the moving mechanism, the two pushers are prone to relatively large deviations during the movement process...

Since it was put into production, the failure rate has remained high, seriously affecting the hot delivery rate of continuous casting slabs

After the equipment personnel and technicians inspected the online equipment maintenance and process execution, they found that the main reason was that the two horizontal steel pushing machines were completely independent equipment. Due to the influence of factors such as pressure difference and different friction coefficients of the moving mechanism, the two pushers are prone to relatively large deviations during the movement process, resulting in the inclination of the steel billet
