Abstract
The invention relates to a steel ladle baking device in steel production. The device comprises a ladle cover, an electric winder, a pulley block and a support. The ladle cover is arranged on the support and comprises an air pipeline, a coal gas control pipeline and an air connecting pipe. The ladle cover is of a two-layer structure, wherein the outer layer is a flame retardant layer, and the inner layer is an air preheating bin. The ladle cover is provided with a combustor connected with two large rotating arms on the ladle cover. The combustor comprises a nozzle and a preheater. The air pipeline is connected to the air preheating bin through one large rotating arm and connected to the nozzle through the air connecting pipe. The coal gas control pipeline is connected to the preheater through the other large rotating arm. The electric winder and the pulley block control tipping driving of the ladle cover, and a steel ladle is lifted in and out. Air and coal gas are preheated through waste heat produced during steel ladle baking at first, and then mixed combustion is carried out, so that low-heating-value coal gas is sufficiently combusted, and the coal gas utilization rate is improved.
Description
technical field
The present invention relates to a kind of metallurgical equipment, particularly relate to the ladle baking facilities in the production of a kind of iron and steel.
Background technology
In molten steel running from steel making working procedure to continuous casting working procedure, the heat-energy losses of molten steel is very large, and about wherein ladle accumulation of heat loss accounts for the half of molten steel heat-energy losses, the baking temperature therefore improving ladle is particularly important.Simultaneously in steel-making, ironmaking production usually with the byproduct such as blast furnace gas, coal gas of converter.Therefore the current problem in order to solve production cost and environmental pollution, usually using the combustion medium of this type of coal gas as ladle baking facilities, but the calorific value of this kind of coal gas is lower, insufficient during burning, cause very large waste, efficiency of combustion is low, and it is longer owing to toasting time of combustion medium, too increase production cost, therefore this just needs first to carry out sufficient preheating to air, coal gas, thus improves the utilization rate of coal gas.
Summary of the invention
The present invention provides a kind of ladle baking facilities to overcome the above problems, and utilizes waste heat during ladle baking first to carry out preheating to air and coal gas, then carries out mixed combustion, make low-heat value gas Thorough combustion, improve the utilization rate of coal gas.
Technical scheme of the present invention is: include clad, electrical hoist, assembly pulley, support, and described clad is arranged on support, includes wind pipeline, coal gas controls pipeline and air tube connector; Described clad is double-decker, skin is flame retardant coating, internal layer is air preheat storehouse, described clad is provided with burner and rotates large arm with two on clad piece and be connected, described burner includes burner and preheater, wind pipeline is connected to air preheat storehouse by rotating large arm, is connected to burner by air tube connector; Coal gas controls pipeline and is connected to preheater by another root rotation large arm; Described electrical hoist and assembly pulley control the driving of tumbling of clad, realize the hanging in of ladle, hang out.
Advantage of the present invention is: air enters from wind pipeline, and preheating is carried out in the air preheat storehouse being connected to clad by rotating large arm, is connected to burner through air tube connector; Low-heat value gas controls pipeline from coal gas and enters, and rotates large arm be connected to the pre-heating cabin of burner by another root, first by air and gas preheating to more than 300 degree, abundant mixed combustion in burner both then making, improves the utilization rate of low-heat value gas.
