Problems solved by technology

However, as the age of the steelmaking converter grows, the lining refractory material is seriously eroded and gradually enters the repairing period, especially after the 1000th furnace, in order to prevent leakage, the frequency of repairing will increase accordingly
However, the repair material is a bulk refractory material. Once the sintering is not good, it is easy to collapse and cause a large spray accident during the process of tapping the furnace due to poor sintering. Therefore, the method of manually throwing slag balls has seriously endangered the life of the throwing personnel. Casualties like this abound in the metallurgical industry

Abstract

An intelligent launching device with essential safety for converter slag ball, including: control system and main equipment, control system: PLC and system start, system stop, motor start, temperature collection, manual launch, lock start, toggle start switch ,, two toggle solenoid valves, trigger solenoid valves, motor relay coils, intermediate relay coils. The main equipment includes: shell, which is equipped with launch tube, launch rod, straight teeth, ejection spring, lock start switch, lock block, trigger cylinder, toggle frame, toggle cylinder, toggle switch, gear, transmission shaft , positioning keys, bearings. A reducer, a receiver, a motor, and a motor start switch are arranged outside the housing. A delivery pipe and a slag ball are installed outside the launch tube. The main points are simple structure, small size, automatic energy storage, reloading, and intelligent launch, which can realize long-range repeated launches, completely eliminate the danger of manual throwing of slag balls, reduce physical labor intensity, and achieve essential safety.

Description

technical field [0001] The invention relates to the field of intrinsic safety of converter smelting process in metallurgical enterprises. Background technique [0002] When steelmaking converters are tapped, in order to reduce the impact of steel slag entering molten steel and affecting the quality of molten steel, slag blocking balls (or slag blocking plugs) must be inserted into the converter in the later stage to prevent the entry of steel slag. The currently known way of inserting slag-stopping balls into the converter is mostly to take the mode of manually throwing slag-stopping balls into the furnace from the furnace mouth. However, as the age of the steelmaking converter grows, the lining refractory material is seriously eroded and gradually enters the repairing period, especially after the thousand furnaces, in order to prevent leakage, the frequency of repairing increases accordingly. However, the repair material is a bulk refractory material. Once the sintering is...
