The invention relates to a tank body structure of a module combined type waste steel preheating device, and belongs to the field of electric furnace steelmaking. A bottom tank is of a U-shaped structure, and material supporting tanks are of L-shaped structures with material supporting bodies; the two material supporting tanks are arranged at the tops of the two sides of the bottom tank correspondingly and are detachably connected with the bottom tank, and the material supporting bodies in the two material supporting tanks are oppositely arranged so that the two material supporting bodies can be positioned on the two sides of an inner cavity of the tank body structure defined by the material supporting tanks and the bottom tank; and the two material supporting bodies are spaced to form a material stacking channel for materials to fall into the bottom tank from the material supporting tanks. According to the tank body structure, a module combined type split structure is adopted, machining and manufacturing are facilitated, and block maintenance and replacement are facilitated; and the stacking type of waste steel in a tank body is reconstructed, a cavity formed by the material supporting bodies and a tank bottom can serve as a smoke dispersion cavity, the smoke dispersion cavity can disperse high-temperature smoke into gaps of the waste steel, the side face of a waste steel material pile can be preheated, and penetrating type preheating can also be achieved.
Description
technical field [0001] The invention belongs to the field of electric furnace steelmaking, and in particular relates to a tank body structure of a modular combined type scrap steel preheating device. Background technique [0002] CONSTEEL horizontal continuous feeding electric arc furnace uses flue gas to preheat scrap steel, which has a certain energy-saving effect in actual production. However, because the flue gas can only preheat the surface or near the surface of the scrap steel during the horizontal continuous feeding process, the average preheating temperature is not high, and the energy saving effect is limited. However, the flue gas in the shaft furnace can penetrate the scrap steel layer, so the effect of preheating the scrap steel is better, and the electric energy consumed for smelting is also lower. If the penetrating preheating can be realized in the horizontal continuous feeding, and the primary energy can be selected to assist the preheating of scrap steel, ...
