Precise pouring device for mold slag in front of alloy electroslag smelting furnace

Abstract

The invention belongs to the field of steelmaking, and particularly relates to a precise casting powder pouring device arranged in front of an alloy electroslag smelting furnace. The precise casting powder pouring device comprises a steel frame, an arc-shaped bracket of which the two sides of the front portion are hinged to the steel frame, a hoisting and lifting device connected to the back end of the bracket and at least one group of fixing and locking devices arranged on the bracket; the hoisting and lifting device comprises a jacking oil cylinder, an adjusting frame beam and a chain, wherein the adjusting frame beam is fixedly connected to the top of a piston rod of the jacking oil cylinder, the two ends of the adjusting frame beam are provided with chain wheels, the chain is wound on the chain wheels, the two ends of the chain are fixedly connected to the steel frame and the back end of the bracket respectively, and the distance that the front end of the bracket stretches out of the steel frame is smaller than 1 / 6 of the length of the bracket. According to the precise casting powder pouring device, the steel frame made of steel is adopted as a base to bear the semi-arc-shaped bracket, and a material bucket is fixed through cooperation of the bracket and the fixing and locking devices after being placed on the bracket. The device is simple and compact in structure, convenient to use, safe, stable, high in bearing force and low in cost.

Description

technical field [0001] The invention belongs to the field of steelmaking, and in particular relates to a device for accurately dumping mold slag in front of an alloy electroslag smelting furnace. Background technique [0002] In the special alloy smelting steel plant, many alloys, mold slag and other materials are filled in 210L large-opening iron drums, and the material loading capacity is about 500-1000 kg. It is extremely inconvenient to accurately take materials during the production process, which is neither safe nor efficient. . In the production of special alloy smelting steel plants, when taking alloy materials filled in 210L large-opening iron drums, oil drum trucks are generally used instead for the convenience and accuracy of material picking, but the load of oil drum trucks sold in the market is only 200kg , The structure is light and thin. When dumping, it only depends on the upper and lower two buckles to dump it in a back-lifting manner. Due to the heavy mate...

[0002] In the special alloy smelting steel plant, many alloys, mold slag and other materials are filled in 210L large-opening iron drums, and the material loading capacity is about 500-1000 kg. It is extremely inconvenient to accurately take materials during the production process, which is neither safe nor efficient.

In the production of special alloy smelting steel plants, when taking alloy materials filled in 210L large-opening iron drums, oil drum trucks are generally used instead for the convenience and accuracy of material picking, but the load of oil drum trucks sold in the market is only 200kg , The structure is light and thin. When dumping, it only depends on the upper and lower two buckles to dump it in a back-lifting manner. Due to the heavy material, this method can easily cause the barrel mouth to deform and fall, which poses a great safety hazard; The unilateral turbine transmission drives the rotating shaft to realize tilting, which is not conducive to control due to the large load torque requirement and large operation labor intensity
