Description

Technical Field

[0001] The utility model relates to the technical field of metal chromium smelting, in particular to a metal chromium smelting furnace. Background Art

[0002] Metal smelting is the process of changing metal from a combined state to a free state. Reducing agents such as carbon, carbon monoxide, and hydrogen react with metal oxides at high temperatures to obtain metal elements. The metal smelting furnace uses the induction heating effect to heat and melt the materials.

[0003] Although the hydraulic CNC bending machines currently used can meet the use requirements, they still have defects in the actual application process. For example, an environmentally friendly metal smelting furnace for ferrous metal smelting provided by the authorization number CN213778619U includes a bottom plate, a plurality of supporting legs are arranged under the bottom plate, a plurality of supporting columns are vertically arranged at the edges around the upper surface of the bottom plate, a top plate is horizontally arranged on the upper surface of the supporting columns, a smelting furnace body is arranged in the middle of the upper surface of the bottom plate, a first sealing cover is arranged on the top of the smelting furnace body, and the inner wall of the smelting furnace body and the first sealing cover are both provided with an insulation layer. A heating plate is horizontally arranged at the inner bottom of the insulation layer, a groove is arranged on the top side wall of the smelting furnace body, a protrusion is arranged at the bottom of the first sealing cover, and the groove matches the protrusion, a discharge port is arranged at the bottom of the smelting furnace body, and a handle is arranged at the top of the discharge port; a cylinder is vertically arranged downward in the middle of the upper surface of the top plate, and by arranging the smelting furnace body and the first sealing cover, raw materials can be added through the opening at the top of the smelting furnace body, and slag can also be cleaned through the opening.

[0004] Although the above-mentioned device can process and purify the flue gas generated by smelting in the smelting furnace, the existing metal smelting furnace generally uses an induction heating layer in the furnace body to heat the material in the furnace body. The material close to the inner wall of the furnace body is heated faster, while the material located in the center of the furnace body is heated slower, resulting in uneven heating of the material, thereby affecting the smelting efficiency.
