Rail bracket type steel ladle adding cover device

Abstract

The invention provides a track bracket type steel ladle cover adding and removing device. The track bracket type cover adding and removing device is arranged and used for covering a steel ladle, provided with hinge bases, with a special steel ladle cover, a steel ladle car stops in front of a bracket device after conveying the steel ladle to a finery inlet, the bracket device advances along tracks till making contact with three hanging rings on the ladle cover, and at the moment, the bracket device drives the ladle cover to rise together when pushed by rising power, steel ladle cover hinges are disengaged from the steel ladle hinge bases and the steel ladle cover is left on the bracket device. Molten steel runs in the reverse direction and stops below the bracket device after refining is completed, the bracket device drives the steel ladle cover to begin to fall together, and after the steel ladle cover hinges touch the steel ladle hinge bases, the bracket device stops falling and starts to retreat along the tracks to the waiting position. By means of the track bracket type steel ladle cover adding and removing device, the cover pick-up and adding actions are achieved through the free movement of the special steel ladle cover and the bracket device along the tracks, and the structure is simple and reliable.

Description

technical field [0001] The invention relates to a track bracket type steel ladle capping device, which is applied to the automatic capping of steel ladles. Background technique [0002] At present, in the domestic metallurgical industry, in the steelmaking process, the ladles are operated online and open. The heat dissipation area of ​​the ladle is large, the heat loss is serious, the temperature drop is large, and the temperature difference between the surface temperature and the internal temperature of the molten steel in the ladle is large, which seriously affects steel products. Quality, when the online ladle is empty, the heat loss in the empty ladle is serious, and the lining of the ladle turns black. When the molten steel is received again, the lining absorbs part of the heat, which reduces the temperature of the molten steel. To maintain the temperature of the molten steel, the only way to increase the tapping temperature of the converter is to greatly increase To re...

Problems solved by technology

[0002] At present, in the domestic metallurgical industry, in the steelmaking process, the ladles are operated online and open. The heat dissipation area of ​​the ladle is large, the heat loss is serious, the temperature drop is large, and the temperature difference between the surface temperature and the internal temperature of the molten steel in the ladle is large, which seriously affects steel products. Quality, when the online ladle is empty, the heat loss in the empty ladle is serious, and the lining of the ladle turns black. When the molten steel is received again, the lining absorbs part of the heat, which reduces the temperature of the molten steel. To maintain the temperature of the molten steel, the only way to increase the tapping temperature of the converter is to greatly increase To reduce the cost of steelmaking, most steel mills set up online ladle baking devices in the steelmaking workshop to increase the temperature of the empty ladle, which increases the number of online ladles, reduces the turnover rate, and increases additional ladle operating costs and maintenance costs.

, in the cold season, the temperature drop of the ladle is obvious, and the ladle is open to run, and the dust generated, in the hot season, the heat dissipation of the ladle increases the ambient temperature of the workshop, which makes the working environment of the workers worse

The heat loss of the open ladle is serious, which increases the cost of steelmaking, affects the quality of steel products, and causes pollution to the working environment and high temperature.
