Description

Technical Field

[0001] The utility model relates to the technical field of steelmaking processing, in particular to a rapid cooling device for ash. Background Art

[0002] The main raw materials for steelmaking are molten iron or pig iron with a high carbon content and scrap iron and steel. In order to remove impurities in the molten iron, it is also necessary to add oxidants, deoxidizers, slag-making materials, and ferroalloys to the molten iron to adjust the composition of the steel. After the molten iron or pig iron with a high carbon content is added to the steelmaking furnace, it undergoes processes such as oxygen blowing, adding ore, and decarbonization to oxidize and remove impurities in the molten iron. Finally, alloys are added for alloying to obtain molten steel. There are three types of steelmaking furnaces: open-hearth furnaces, converters, and electric furnaces. The open-hearth steelmaking method has been gradually eliminated due to high energy consumption and poor working environment. Converter and open-hearth steelmaking is to first load the molten iron into the mixing furnace for preheating, add scrap steel into the converter or open-hearth furnace, and then use a mixing car to add the high-temperature molten iron in the mixing furnace into the converter or open-hearth furnace for melting and heating. When the temperature is appropriate, it enters the oxidation period. Electric furnace steelmaking is to add all the cold scrap steel into the electric furnace steel, and then enter the oxidation period after a long period of melting and heating.

[0003] At present, when steelmaking is carried out on the market, it is necessary to carry out the steps of mining → ore dressing → sintering → ironmaking → steelmaking → hot rolling → cold rolling → silicon steel. In actual use, when steelmaking is carried out in the sintering process, it is necessary to mix and granulate the powdered iron ore, various fluxes and fine coke, and then add them to the sintering machine through the distribution system. The fine coke is ignited by the ignition furnace, and the sintering reaction is completed by exhaust windmill. The high-temperature sintered ore is crushed, cooled and screened, and then sent to the blast furnace as the main raw material for smelting molten iron. At this time, part of the ash produced by steelmaking will enter the subsequent filtration equipment with the gas for filtration. Because the temperature of the gas and the ash in the gas is too high, the internal part of the subsequent filtration equipment will be damaged. Utility Model Content
