A converter movable smoke hood positioning and fall prevention device

Abstract

The invention discloses a locating and falling preventing device for a moving smoke cover of a rotary furnace. The locating and falling preventing device is composed of multiple connecting units for connecting the moving smoke cover of the rotary furnace with a smoke cover fixing beam. Each connecting unit comprises a fixed part and a moving part. The tops of the fixed parts are installed on the smoke cover fixing beam through a girder fixing base. The bottoms of the moving parts are installed around the moving smoke cover through a smoke cover fixing base. The fixed parts and the moving partsare installed in a guiding manner through sliding pairs. The smoke cover fixing base is provided with chains for hoisting. The chains for hoisting are connected with a hoisting device arranged on thesmoke cover fixing beam. The device further has double falling preventing functions on the basis of guiding, the function of a set square and a guide groove is utilized, guiding is more stable, the falling preventing function can also be achieved, and the chains in a moving casing pipe and a fixed casing pipe can have a secondary falling preventing function. After the device is installed on the moving smoke cover, the fault rate is reduced obviously, and meanwhile the service life of the moving smoke cover is prolonged.

Description

technical field [0001] The invention belongs to the field of steelmaking production equipment, and relates to an auxiliary facility of a converter movable fume hood, in particular to a converter movable fume hood positioning and anti-falling device. Background technique [0002] Converter movable hoods are widely used in the steelmaking plants of every iron and steel enterprise. This equipment plays a pivotal role in the steelmaking plants of iron and steel enterprises. It plays a role in recycling the smoke and dust produced by the converter, avoiding pollution to the environment and protecting the environment. role. During the production process, the movable fume hood needs to move up and down. During converter smelting, the movable fume hood should fall to the furnace mouth of the converter. When the converter pours molten steel, the movable fume hood must be lifted up, and the movable fume hood is suspended in the air during the smelting process, which will cause Vibrat...

AI Technical Summary

Problems solved by technology

During the production process, the movable fume hood needs to move up and down. During converter smelting, the movable fume hood should fall to the furnace mouth of the converter. When the converter pours molten steel, the movable fume hood must be lifted up, and the movable fume hood is suspended in the air during the smelting process, which will cause Vibration and displacement, these situations will cause faults such as breakage of the movable hood wire rope, movable hood stuck at the water sealing knife, etc. These faults take a long time to deal with, seriously affecting the production of the steel mill, and at the same time leading to an increase in cost. Moreover, maintenance personnel deal with faults on the fume hood, which has a high risk factor and is prone to personal injury accidents
