A balanced heating type resistance furnace

Abstract

The invention discloses a balanced heating type resistance furnace, which belongs to the field of electric furnaces. A balanced heating type resistance furnace includes a resistance furnace body. There are multiple uniform temperature adjustment holes in the temperature plate, and multiple air uniformity holes connected to the uniform temperature adjustment holes are opened in the partition uniform temperature plate. Air drum type support cells are arranged in the uniform temperature adjustment holes, which can pass through the air. The role of the drum-type support bag and the heat radiation plate is to conduct contact heat conduction and partition heat radiation to the heat generated by the electric heating element to improve the heat transfer efficiency of the electric heating element, and then conduct auxiliary heat conduction to the area where the material is shielded in the furnace, effectively improving The temperature balance in the furnace improves the heating efficiency of the resistance furnace body to the material, effectively improves the heating uniformity of the material and improves the smelting quality of the material, and at the same time reduces the energy loss of the resistance furnace body and improves the environmental protection of the resistance furnace body.

Description

technical field [0001] The invention relates to the field of electric furnaces, and more specifically, relates to a balanced heating resistance furnace. Background technique [0002] Resistance furnace is an electric furnace with Joule heat generated by current passing through a conductor as the heat source. With the invention of nickel-chromium alloy, resistance furnaces have been widely used in industry by the 1920s. Industrial resistance furnaces are generally made of electric heating It is composed of components, masonry, metal shell, furnace door, furnace machinery and electrical control system, etc., and the heating power ranges from less than one kilowatt to several thousand watts. [0003] Resistance furnace is divided into direct heating and indirect heating according to the way of electric heat generation. At present, most resistance furnaces are indirect heating resistance furnaces, which are equipped with a resistance body specially used to realize electric-ther...

AI Technical Summary

Problems solved by technology

[0004] When the resistance furnace smelts metals with low melting points such as aluminum and magnesium, in order to improve the uniformity of the temperature in the furnace, fans are mostly used to enhance the heat transfer in the furnace by convection, but sufficient flow is required due to gas convection. Space to complete the conduction of heat energy. When there are materials stored in the furnace, the materials will block the air flow, reducing the fluidity of the gas in the furnace, affecting the temperature balance in the resistance furnace, and reducing the working efficiency of the resistance furnace. , thus increasing the energy loss of the resistance furnace
