Novel converter covering and uncovering device

Abstract

The invention discloses a novel converter covering and uncovering device. The novel converter covering and uncovering device comprises a converter body, bottom plates and a supporting frame, wherein one side, close to the bottom, of each of the two bottom plates is fixedly connected with the supporting frame; the upper surface of the supporting frame is fixedly connected with the bottom of the converter body; a heat preservation cavity is formed in the inner side of the converter body; a converter groove is formed in the inner wall, close to the bottom, of the heat preservation cavity; a cavity is formed in the inner wall, close to the top, of the heat preservation cavity; two opposite racks are fixed on the inner wall of the cavity; two opposite limiting grooves are formed in each of thefront side and the rear side of the converter body; the lower end of one side of each bottom plate is fixedly connected with a mounting plate; and a driving mechanism for enabling a second rotary shaft to rotate is fixed at the top of each mounting plate. According to the novel converter covering and uncovering device, the structure is ingeniously designed; on one hand, the effect of rapidly covering and uncovering is realized and molten iron is prevented from being in direct contact with air; and on the other hand, the heat storage capability of a cambered surface cover is strong, so that theheat exchange is further reduced and the energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of removing and covering a converter, in particular to a novel device for removing and covering 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. Its main features are: relying on the physical heat of the liquid pig iron in the converter and the heat generated by the chemical reaction of various components in the pig iron (such as carbon, manganese, silicon, phosphorus, etc.) Ingredients and temperature required. Furnace materials are mainly molten iron and slagging mater...

Problems solved by technology

[0003] Therefore, people have proposed a converter cover removal device, such as a converter cover removal device and method provided by Chinese patent CN201910168574.2. Through the design and use of a series of structures, the cover plate and the converter body can be fastened. or separation, thereby achieving the effect of removing the cover, avoiding the direct contact of the molten iron with the air, thereby reducing the heat exchange, but in actual use, the work efficiency is low due to the fastening or separation of the cover plate and the converter body.
