Combustion-heated heating ball

Abstract

The invention relates to a combustion-heated heating ball, which is a hollow ball body compounded by a fireproof material layer and a combustible material layer, and a centripetal through hole is manufactured on the ball body. By adding the heating ball to the melt liquid metal surface of the high-temperature conveying equipment during the metallurgical production, the combustible material of the ball body is contacted with the oxygen above the melt liquid metal surface to carry out combustion reaction to emit heat under the radiation and heating action of the high-temperature liquid metal, so as to heat the liquid metal and the equipment; at the same time, the fireproof ball housing not only can serve as the carrier of solid fuel, but also can be used for thermal insulation, so as to reflect and block the combusting heat and the heat emitted by the liquid metal, as a result, the heating effect of the heating ball is improved, the thermal insulation function is achieved, the temperature drop speed of the liquid metal is reduced, and the purpose of energy saving is achieved. Due to the heat emitted by the heating ball, the temperature surrounding the openings of the liquid iron ladle and the steel ladle for containing the melt liquid metal in the steel industry is kept very high, as a result, the slag bonding problem on the brims of the liquid iron ladle and the steel ladle is greatly reduced.

Description

technical field [0001] The invention belongs to the field of high-temperature heating technology, and relates to a heating process for specific material surfaces or equipment, especially heating and heat preservation in the process of production, transportation and storage of molten liquid metal in the metallurgical industry. A heating bulb that burns and generates heat. Background technique [0002] my country's high-temperature industry is a large energy consumer. For example, in the production process of non-ferrous metallurgy and ferrous iron and steel metallurgy, it needs to consume a lot of heat energy to heat up and keep the molten metal warm. For example, in the converter steelmaking process in the iron and steel industry, a large amount of energy needs to be consumed to raise the temperature of high-temperature molten iron (1400°C) and molten steel (1650°C), while in the storage, transportation, refining and continuous casting of molten iron and steel In the proces...

AI Technical Summary

Problems solved by technology

For example, in the converter steelmaking process in the iron and steel industry, a large amount of energy needs to be consumed to raise the temperature of high-temperature molten iron (1400°C) and molten steel (1650°C), while in the storage, transportation, refining and continuous casting of molten iron and steel During the process, the heat dissipation of molten iron and molten steel causes a lot of energy to be wasted in vain

In order to reduce heat dissipation, the existing technology is to add a covering agent on the surface of molten iron and molten steel to enhance heat preservation, but the heat insulation effect of this passive heat insulation is relatively poor, and the problem of sticky slag at the mouth of the ladle and ladle is more serious

[0003] Through the search, the heating bulb material is a new type of mobile heating method and heating carrier, and no published patent documents related to this patent application have been found.
