Abstract
The utility model relates to a ladle roasting device in steel manufacture, which comprises a cover, an electric hoist and a bracket, wherein the cover is arranged on the bracket, and the ladle roasting device further comprises an air pipeline, a gas control pipeline and an air connecting pipe, the cover is in a double-layer structure, the outer layer of the cover is a fire layer, and the inner layer thereof is an air preheating bin, the cover is provided with a burner to connect with two large rotary arms on the cover, the burner consists of a nozzle and a preheater, the air pipeline is connected on the air preheating bin through the large rotary arm, and is connected to the nozzle through the air connecting pipe, and the gas control pipeline is connected to the preheater through the other large rotary arm. The ladle roasting device utilizes the preheating during roasting ladles to preheat air and gas over 300 DEG C, then fully mixes and combusts the air and gas in the burner, and improves the availability ratio of low-calorific value gas.
Description
Technical field
The utility model relates to the ladle baking facilities in a kind of iron and steel production.
Background technology
In the steel-making of iron and steel processing factory, ironmaking are produced usually with byproducts such as blast furnace gas, coal gas of converter.Therefore at present in order to solve production cost and environmental pollution problems, usually with the combustion medium of this type of coal gas as ladle baking facilities, but the calorific value of this kind coal gas is lower, insufficient during burning, caused very big waste, efficiency of combustion is low, and owing to the time of baking combustion medium is longer, also increased production cost, so this just need carry out sufficient preheating earlier to air, coal gas, thereby improve the utilization rate of coal gas.
The utility model content
The utility model provides a kind of ladle baking facilities in order to overcome the above problems, and the preheating when utilizing ladle baking is carried out preheating to air and coal gas earlier, carries out mixed combustion again, 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, support, described clad is arranged on the support, also include air duct, coal gas control pipeline and air tube connector, described clad is a double-decker, outer is that flame retardant coating, internal layer are the air preheat storehouse, be provided with on the described clad burner and with clad on two rotate big arms and be connected, described burner includes burner and preheater, air duct is connected to the air preheat storehouse by rotating big arm, is connected to burner by the air tube connector; Coal gas control pipeline rotates big arm by another root and is connected to preheater.
The utility model has the advantages that: air enters from air duct, carries out preheating by rotating the air preheat storehouse that big arm is connected to clad, is connected to burner through the air tube connector; Low-heat value gas enters from coal gas control pipeline, rotates the preheating storehouse that big arm is connected to burner by another root, earlier with air with more than gas preheating to 300 degree, makes both fully mixed combustion in burner then, has improved the utilization rate of low-heat value gas.
