Description

Anti-dropping device for feeding wire rope on vacuum induction furnace

technical field

The invention relates to the technical field of steel-making production equipment, in particular to an anti-dropping device for feeding steel wire ropes on a vacuum induction furnace.

Background technique

The vacuum induction furnace in the metallurgical industry is smelted and produced in a vacuum state. At present, the domestic vacuum induction furnace has a charging chamber, and its temperature measurement, feeding and sampling are all completed in a vacuum state by means of a wire winch lifting system. Its structure is that the hoisting end is coiled with a large wheel wire rope, and the small wheel end is positioned by a fixed pulley. The lifting length of the wire rope is controlled by the number of turns of the servo motor encoder. During the feeding process, the barrel connected by the heavy hammer touches the bottom. Or when the crucible sticks to the scrap steel, the lifting and hoisting wire rope is easy to change jobs. Since the value of the lift and drop position encoder remains unchanged by default, the number of turns of the hoisting and lifting rotation is also the same. When the steel wire rope is recycled due to the wire rope skipping, the actual wire rope will have some rope hanging on the upper feeding isolation due to the smaller diameter of the recycling coil. At the bottom of the valve, the steel wire rope cannot be completely recovered, and the isolation valve cannot be completely sealed when the isolation valve is closed. The oxygen, nitrogen and other gases in the atmosphere entering the melting chamber will cause a sudden increase in the oxygen and nitrogen content in the molten steel, which affects the quality of important products such as high-temperature alloy steel and gas steel. cause major quality accidents.
