Description

Technical Field

[0001] The utility model relates to the technical field of resistance furnaces, in particular to a discharge device for a graphitized carburizer resistance furnace. Background Art

[0002] During the smelting process of steel products, the smelting loss of carbon in the molten iron often increases due to factors such as long smelting time, holding time, and overheating time, resulting in a decrease in the carbon content in the molten iron, which causes the carbon content in the molten iron to fail to reach the theoretical value expected for refining. In order to make up for the carbon content burned during the steel smelting process, the carbon-containing substance added is called a recarburizer. During the heating process of the recarburizer, a resistance furnace is required to heat it.

[0003] Most of the existing resistance furnaces are of sliding door design. The sliding door needs to be opened to put the material in for heating. After heating, the sliding door needs to be opened again to take out the material. This is not only cumbersome to operate, but also easy to cause a large amount of material to be exposed during the material removal process, resulting in material waste. At the same time, it increases the difficulty of unloading the recarburizer after heating. Therefore, there is an urgent need for a discharge device for a graphitized recarburizer resistance furnace to solve this problem. Utility Model Content

A collecting box is provided under the discharging shell, and a material guide bag is installed at the bottom of the discharging shell. The prismatic guide block will first divert the material to prevent blockage, and then the feeding column will rotate to discharge the material in sequence.
