Smelting furnace used for steel material

Abstract

The invention discloses a smelting furnace used for a steel material. The smelting furnace comprises a furnace body. The furnace body is composed of a breaking chamber and a smelting chamber. The breaking chamber is connected with the smelting chamber through a discharging hopper and communicates with the smelting chamber. Supporting frames are arranged at the bottom of the furnace body, and a first discharging opening and a second discharging opening are formed in the two ends of the bottom of the furnace body correspondingly. A feeding hopper is arranged at the top end of the furnace body. Extruding blocks are arranged on the two sides of the inner wall of the feeding hopper, and the extrusion blocks are connected with the inner wall of the feeding hopper through compression springs. Theother end of each compression spring is provided with an extrusion motor, and the extrusion motors are arranged on the outer wall of the feeding hopper. A dust suction pipe is arranged on one side ofthe top end of the breaking chamber, one end of the dust suction pipe penetrates in the breaking chamber, the other end of the dust suction pipe is connected with a gas suction pump, and the other end of the gas suction pump is connected with a dust collection box. By means of the smelting furnace used for the steel material, the steel material needing to be smelted can be extruded and smashed, smoke generated in the smelting process can be effectively collected and filtered, and cleanliness of the working environment is ensured.

Description

technical field [0001] The invention relates to the technical field of smelting, in particular to a smelting furnace for steel. Background technique [0002] Smelting is a refining technology, which is used to extract metals from ores by roasting, smelting, electrolysis and using chemical agents to reduce impurities contained in metals or increase certain components in metals, and smelt into required metals. Steelmaking mainly uses pig iron smelted in blast furnaces, sponge iron smelted by direct reduction ironmaking, and scrap steel as raw materials. Steel is smelted in different ways, and the existing smelting furnaces are designed for solid-state dissolution of metals of different sizes. The effect and efficiency are different, and it is easy to produce unbalanced dissolution, and many gases that pollute the atmosphere will be produced during the smelting process, and some gases may be poisonous, which needs further improvement.
