An automatic control system for a slag ball truck

Abstract

The invention discloses an automatic control system for a slag blocking ball car, which relates to the technical field of metallurgical equipment, comprising a PLC control system, an ultrasonic detection system, a rear position limit system, and a flower-shaped contact sensor fixedly connected to the body of the slag blocking ball car; The ultrasonic detection system includes an ultrasonic limit device; the rear limit system includes a rear limit rod that is fixedly installed on the body of the slag blocking vehicle and a rear limit that is arranged on the travel route of the slag blocking vehicle. A striker rod; the flower-shaped contact sensor includes a connecting rod that is fixedly connected with the body of the slag blocking ball and extends to the rear of the slag blocking ball car, a turntable hinged on the connecting rod, and a circumference along the turntable that is fixedly connected to the side wall of the turntable. Multiple contact bars evenly distributed. The invention adopts multiple positioning or detection systems to ensure positioning and measurement accuracy, can effectively prevent the slag blocking truck from colliding with the ground staff, realize automatic movement to a designated location, improve the degree of automation, and improve labor productivity.

Description

technical field [0001] The invention relates to the technical field of metallurgical equipment, in particular to an automatic control system for a slag-blocking ball car. Background technique [0002] In the late stage of converter steelmaking and tapping, in order to prevent the converter slag from flowing into the molten steel tank, resulting in a quality accident caused by excessive phosphorus reversion in the molten steel, a slag blocking ball is usually thrown into the converter to block the converter slag. The slag blocking ball is generally delivered by the slag blocking ball cart. The specific operation steps are: first move the slag blocking ball cart to the vicinity of the converter, and then clamp the steel bar on the slag blocking ball with the slag blocking rod in front of the slag blocking ball cart. , and finally control the slag blocking rod to put the slag blocking ball into the designated position in the converter. In the current slag-blocking carts, the o...
