Capping device and method for iron mixing vehicle

Abstract

The invention discloses a capping device and method for an iron mixing vehicle. The capping device comprises a steel structure welded and fixed to a driven end rack. A hydraulic station and an electrical device are installed on the steel structure. A rotating vehicle frame device is installed on the steel structure through a rotating shaft so that the rotating vehicle frame device can rotate relative to the steel structure with the rotating shaft as the center after being stressed. A walking beam device is installed at the upper portion of the rotating vehicle frame device. By means of the capping device and method for the iron mixing vehicle, heat losses of molten iron in the transporting and waiting processes can be obviously reduced, pollutants such as smoke discharged into the atmosphere can also be effectively reduced, the environment-friendliness index of the iron mixing vehicle is increased, the purposes of energy saving and environment friendliness are achieved, the capping device is low in price, convenient to install and maintain, easy to operate and suitable for application and popularization.

Description

technical field [0001] The invention relates to the technical field of metallurgical equipment, and relates to a capping device and a capping method for a mixed iron car applied to a mixed iron car. Background technique [0002] Molten iron is the main raw material for steelmaking, generally accounting for 70% to 100% of the charge. The temperature of molten iron has a great influence on steelmaking. The temperature of molten iron is a sign of how much physical heat is brought into the converter. According to the converter steelmaking process, the heat of converter smelting basically comes from the physical heat and chemical heat of molten iron. The physical heat of molten iron accounts for about 50% of furnace heat income. Under the condition of constant chemical heat, the physical heat of molten iron is the key factor to determine whether the smelting can proceed smoothly. The low temperature of molten iron causes large blowing loss, high consumption of steel material, u...

Problems solved by technology

[0009] According to the above-mentioned technical problems, a capping device and a capping method for a mixed iron car are provided, which are used to solve the problem that the existing mixed iron car has no cover, causing a large amount of dust and smoke generated in the tank to be directly discharged into the air. The surrounding environment causes pollution, and the opening of the tank body also reduces the temperature of molten iron quickly, causing a large amount of energy loss and increasing the cost of steelmaking.
