Description
Technical Field
The invention relates to the technical field of ferrous metallurgy processes, in particular to an ash discharging device for steelmaking and a using method thereof.
Technical Field
Steel, which is a general name for iron-carbon alloy with carbon content between 0.02% and 2.11% by mass, has a long history of application and research on steel by human beings, but until the invention of the 19 th century bailey steel-making method, the preparation of steel is a high-cost and low-efficiency work, and nowadays, steel becomes one of the most used materials in the world with low price and reliable performance, and is an indispensable component in the building industry, the manufacturing industry and the daily life of people.
Steelmaking refers to controlling the carbon content (generally less than 2%), eliminating P, S, O, N and other harmful elements, retaining or increasing Si, Mn, Ni, Cr and other beneficial elements and adjusting the proportion among the elements to obtain the best performance. China is one of the earliest countries in the world that produce steel. Archaeologists have developed a copper grid "iron sword" in graves in spring and autumn late stage of Changsha populus family in Hunan, and the result proves that the steel is made through metallographic examination. This is the earliest steel entity in china we have seen to date. It shows that steel-making production is performed in China from late spring and late autumn, and the steel-making production has more than 2500 years of history in China. The main raw materials for steel making are molten iron or pig iron with high carbon content and waste steel. In order to remove impurities in molten iron, it is necessary to add an oxidizing agent, a deoxidizer, a slag-forming material, and a material such as an iron alloy to the molten iron to adjust the composition of steel. After molten iron or pig iron with high carbon content is added into a steel-making furnace, the impurities in the molten iron are oxidized and removed through the procedures of oxygen supply blowing, ore addition, decarburization and the like, and finally alloy is added for alloying, so that molten steel is obtained. The steel-making furnace includes 3 kinds of open-hearth furnace, converter and electric furnace, and the open-hearth furnace steel-making method is gradually eliminated due to high energy consumption and poor operation environment. The converter and open hearth steelmaking is carried out by charging molten iron into a mixer for preheating, charging scrap steel into the converter or open hearth, charging high-temperature molten iron in the mixer into the converter or open hearth by a mixer car for melting and raising temperature, and entering into oxidation period when the temperature is proper. In the electric furnace steelmaking, cold scrap is completely added into electric furnace steel, and the electric furnace steel is melted and heated for a long time and then enters an oxidation period. (1) And (5) a melting process. Molten iron and scrap steelAnd in the low-temperature melting process, the C, Si, P and S are oxidized, even if the simple substance state impurities are changed into compound state impurities, the impurities can be further removed in the later period. The oxygen is derived from rust (component Fe) in the charge2O3·2H2O), iron scale, added iron ore, and oxygen in the air and oxygen blowing. The oxidation of various impurities is carried out between the interface of the slag and the molten steel. (2) And (4) an oxidation process. The oxidation process is a decarburizing, dephosphorizing, degassing and impurity-removing reaction carried out at high temperature. (3) Deoxidizing, desulfurizing and tapping. In the final stage of oxidation, steel contains a large amount of excess oxygen, the excess oxygen in the molten steel is removed by adding massive or powdery ferroalloy or multi-element alloy into the molten steel, the generated harmful gas CO is discharged along with furnace gas, the generated slag can be further desulfurized, namely, in the final tapping process, the slag and the steel are intensively mixed and washed, and the desulfurization reaction is increased. (4) And (5) refining outside the furnace. Molten steel smelted from a steelmaking furnace contains a small amount of gas and impurities, and the molten steel is generally injected into a refining ladle and subjected to procedures of argon blowing, degassing, ladle refining and the like to obtain relatively pure steel. (5) And (5) casting. The pure molten steel from the steel furnace or the refining furnace can be tapped after the temperature is proper and the chemical components are properly adjusted. And (3) the molten steel is taken out of the ladle and is put into an ingot mould or a continuous casting machine, and a steel ingot or a continuous casting billet is obtained.
The belt feeding in the steel smelting process is that materials are conveyed to a storage bin through a belt material roller, fall into a turning plate through a material guide plate, are guided to a discharging hopper and finally enter the storage bin. A gap is reserved between the belt and the guide plate on the belt roller, materials are conveyed to the guide plate, the whole process is parabolic, part of ash powder falls into the gap between the belt and the guide plate, the ash discharging hopper is provided with a single opening and two openings below the guide plate, and the main function is to discharge the ash powder. The prior art is that the material loading process powder gets into the ash discharge hopper and gets into two different feed bins simultaneously, causes the string ash phenomenon, influences molten steel quality, and smelting 1215 steel has appeared 3 stove steel composition problems (oxygen is low), surveys afterwards: the 1215 steel of smelting needs to add the pyrite, and the pyrite storehouse is corresponding is high aluminium slag storehouse (No. one storehouse), and the powder falls into the quality accident that the pyrite storehouse (No. two storehouses) caused from the ash hopper trompil during high aluminium slag is gone up, and current production needs can not be satisfied to current device, and the material cleanliness factor reduces, can not provide high-quality material and supply production to influence product quality.
