A steel pusher control system for steel rolling heating furnace

Abstract

The invention discloses a steel pusher control system for a steel rolling heating furnace, comprising: two displacement detection units for real-time measurement of the displacement values ​​of the first steel pusher and the second steel pusher during the steel pushing process; the starting position The proximity switch is used to calibrate the initial position of the first steel pusher and the second steel pusher; the middle position proximity switch is used to calibrate the middle position of the first steel pusher and the second steel pusher; the end position proximity switch is used to It is used to calibrate the end positions of the first steel pusher and the second steel pusher; the main control unit calculates the deviation compensation correction amount by calling the internal clock interrupt processing program and the deviation compensation algorithm, and controls the cylinder drive unit to dynamically correct the deviation to achieve synchronization . The steel pusher control system for the steel rolling heating furnace of the present invention can realize the synchronous operation of two sets of independent steel pushers, which can greatly improve the automation degree and work efficiency of the equipment operation, ensure that the system meets the company's requirements for improving the heat delivery rate, and realize the reduction of heat transfer rate. The goal of this efficiency increase.

Description

technical field [0001] The invention relates to the technical field of iron and steel production, in particular to a pusher control system for a steel rolling heating furnace. Background technique [0002] The company's rolling heating furnace hot-feeding traverse pusher is an important production equipment in the hot-feeding and hot-charging process of continuous casting billets. Since the start of production, the failure rate has remained high, which seriously affects the hot delivery rate of the continuous casting slab. After the equipment personnel and technicians checked the online equipment maintenance and process execution, they found that the main reason was that the two traverse pushers were completely independent equipment. The influence of factors such as pressure difference and different friction coefficient of the moving mechanism leads to a relatively large deviation of the two steel pushers during the movement process, resulting in the inclination of the bill...

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
