Description

Technical Field

[0001] This utility model belongs to the technical field of resistance heating furnaces, specifically, it relates to a resistance heating furnace with energy-saving function. Background Technology

[0002] An electric resistance furnace is an industrial furnace that uses electric current to heat heating elements or a heating medium inside the furnace, thereby heating workpieces or materials. It utilizes the heat generated by the passage of electric current through a resistive material. Based on the heat transfer method, electric resistance furnaces are divided into radiant electric resistance furnaces and convection electric resistance furnaces. Radiant electric resistance furnaces primarily use radiant heat transfer, with less convective heat transfer; convection electric resistance furnaces primarily use convective heat transfer, often referred to as air-circulating electric resistance furnaces, relying on hot air for heating, and their furnace temperature is mostly below 650℃. Existing box-type electric resistance furnaces require the use of tongs to remove the heating elements from the furnace body. This puts the operator's arms close to the inside of the furnace, posing a safety hazard due to the risk of burns. Furthermore, the heating elements must be removed and placed individually, a time-consuming process. Since the furnace door remains open during this process, heat dissipates, resulting in energy waste.

[0003] In view of this, this utility model is proposed. Utility Model Content
