Problems solved by technology

[0003] Most domestic iron and steel enterprises generally use open converter steelmaking. The converter is open, and the molten iron is in direct contact with the air. The temperature difference between the molten iron and the converter and the air is large, and heat exchange occurs continuously. A large amount of heat is emitted, which increases energy consumption and affects iron ladle. The life of the lining increases the production cost, so it is necessary to develop a converter and cover device to solve the above problems

Abstract

The invention relates to the technical field of converter covering and uncovering, in particular to a converter covering and uncovering device and method. The device comprises a bottom plate, side plates and a top plate, the left side and the right side of the top of the bottom plate are symmetrically provided with the side plates, the upper ends of the side plates are provided with the top plate,the upper part of the right side plate is provided with a first driving motor, the output end of the first driving motor is provided with a lead screw, and the left end of the lead screw penetrates through the right side plate and is connected with the left side plate through a first bearing pedestal. By means of the design and use of a series of structures, the purpose of buckling or separatinga cover plate and a converter body can be achieved, the effects of covering and uncovering are achieved, molten iron is prevented from making direct contact with air, heat exchange is reduced, energyconsumption is reduced, the service life of an iron ladle lining is prolonged, and the production cost is reduced. The converter covering and uncovering device is novel in structure, reasonable in design, convenient to use and high in popularization value.

Description

technical field [0001] The invention relates to the technical field of uncovering a converter, in particular to a device and method for uncovering a converter. Background technique [0002] Converter (converter), the furnace body can be rotated, and is used for metallurgical furnaces for blowing steel or blowing matte. The furnace body of the converter is made of steel plate, which is cylindrical and lined with refractory materials. It is heated by chemical reaction heat during blowing and does not require an external heating source. It is the most important steelmaking equipment and can also be used for copper and nickel smelting. According to the refractory properties of the lining, the converter is divided into alkaline (with magnesia or dolomite as the lining) and acidic (with silicon material as the lining) converter; according to the part where the gas is blown into the furnace, it is divided into bottom blowing and top blowing. And side blowing converter; according t...
