Abstract
The utility model relates to a steel ladle drying device used for steel production. The steel ladle drying device comprises a ladle cover, an electric winch, a pulley block and a support. The ladle cover is arranged on the support and comprises an air pipeline, a gas control pipeline and an air connecting pipe. The ladle cover is of a double-layer structure. The outer layer of the ladle cover is a refractory layer. The inner layer of the ladle cover is of an air preheating bin. The ladle cover is provided with a burner which is connected with two big rotary arms on the ladle cover. The burner comprises a nozzle and a preheater. The air pipeline is connected to the air preheating bin through one big rotary arm and is connected to the nozzle through the air connecting piece. The gas control pipeline is connected to the preheater through the other big rotary arm. The electric winch and the pulley block control rollover drive of the ladle cover, so that the steel ladle is lifted in or out. Air and gas are preheated through waste heat generated when the steel ladle is dried firstly, mixed burning is conducted secondly, in this way, low-heating-value gas is fully burned, and the utilization rate of gas is increased.
Description
Technical field
The utility model relates to a kind of metallurgical equipment, relates in particular to the ladle baking facilities in a kind of iron and steel production.
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 wherein ladle accumulation of heat loss accounts for half left and right of molten steel heat-energy losses, and the baking temperature that therefore improves ladle is particularly important.Simultaneously in steel-making, ironmaking production usually with byproducts such as blast furnace gas, coal gas of converter.Therefore at present in order to solve the problem of production cost and environmental pollution, the combustion medium using this type of coal gas as ladle baking facilities usually, but the calorific value of this kind of coal gas is lower, insufficient during burning, caused very large waste, efficiency of combustion is low, and because the time of baking combustion medium is longer, also increased production cost, so this just need to first carry out sufficient preheating to air, coal gas, thereby improve the utilization rate of coal gas.
Utility model content
The utility model provides a kind of ladle baking facilities in order to overcome the above problems, and the waste heat while utilizing ladle baking first carries out preheating to air and coal gas, then carries out mixed combustion, and low-heat value gas is fully burnt, and has improved the utilization rate of coal gas.
The technical solution of the utility model is: include clad, electrical hoist, assembly pulley, support, described clad is arranged on support, includes wind pipeline, coal gas control pipeline and air tube connector; Described clad is double-decker, outer is that flame retardant coating, internal layer are air preheat storehouse, on described clad, be provided with burner and be connected with two large arms of rotation on clad, described burner includes burner and preheater, wind pipeline is connected to air preheat storehouse by rotating large arm, by air tube connector, is connected to burner; Coal gas control pipeline rotates large arm by another root and is connected to preheater; The driving of tumbling that described electrical hoist and assembly pulley are controlled clad, realizes hanging in, hanging out of ladle.
The utility model has the advantages that: air enters from wind pipeline, preheating is carried out in the air preheat storehouse that is connected to clad by rotating large arm, through air tube connector, is connected to burner; Low-heat value gas is controlled pipeline from coal gas and is entered, and by another root, rotates the pre-heating cabin that large arm is connected to burner, first by air and gas preheating to more than 300 degree, then make both fully mixed combustion in burner, improved the utilization rate of low-heat value gas.

Fig. 1 is structural representation of the present utility model.
In figure, 1 is clad, the 2nd, rotate large arm, and the 3rd, burner, the 4th, wind pipeline, the 5th, electrical hoist, the 6th, coal gas is controlled pipeline, the 7th, support, the 8th, assembly pulley, the 9th, air tube connector, the 10th, smoke evacuation chimney, the 11st, air preheater, the 12nd, mixed combustion chamber.
Fig. 2 is 3 front view in Fig. 1.
The specific embodiment
A kind of ladle baking facilities, include clad 1, electrical hoist 5, support 7, described clad 1 is arranged on support 7, also include wind pipeline 4, coal gas is controlled pipeline 6 and air tube connector 9, described clad 1 is double-decker, skin is flame retardant coating, internal layer is air preheat storehouse, on described clad 1, be provided with burner 3 and be connected with two large arms 2 of rotation on clad 1, described burner 3 includes mixed combustion chamber 12 and air preheater 11 and smoke evacuation chimney 10, wind pipeline 4 is connected to clad by rotating large arm 2, by hot blast tube connector 8, be connected to burner, coal gas control pipeline 6 rotates large arm 2 by another root and is connected to air preheater 11.Cold air enters and rotates after large arm 2 through wind pipeline 4, and preheating is carried out in the air preheat storehouse being connected on clad 1, then enters in mixed combustion chamber 12 by air tube connector 9; Coal gas is controlled pipeline 6 by coal gas and is transported to another root and rotates the air preheater 11 that large arm 2 enters burner 3 and carry out preheating, then enter in mixed combustion chamber 12 and hot-air mixed combustion, the utility model integral hoisting, on support 7, is controlled the distance of clad 1 and ladle by the power adjustment of electrical hoist 5 and assembly pulley 8.
