Its diameter, specifications, and weight often exceed the transportation conditions, and it is necessary to carry out overall production, installation, and heat treatment on site. In order to ensure uniform heating of the overall heat treatment, large-scale container equipment generally adopts electric heating, so it is necessary to produce a large electric heating furnace on site, and the furnace wall of the electric heating furnace is usually built with modules. The existing electric heating furnace wall module structure is relatively simple, which is installed on the load-bearing columns of the electric heating furnace wall. After the furnace wall module is installed, the insulation cotton and heating device are uniformly installed on the inner side of the furnace wall. However, there are the following technical problems: First, the furnace wall module of the electric heating furnace cannot bear a large load and must be installed on the load-bearing columns of the furnace wall, which increases the complexity and workload of the electric heating furnace production; second, the insulation cotton and heating device of the electric heating furnace can only be installed uniformly after the furnace wall module is installed, which increases the installation workload and installation difficulty; third, when the furnace wall of the electric heating furnace is dismantled, part of the insulation cotton and heating device will be destroyed, which increases the difficulty of reusing and changing the capacity of the electric heating furnace.

The size of the thin steel plate is consistent with the outer contour size of the external frame and is welded to the inner side of the rectangular tube and the short square tube of the external frame. A full circle of fixed rods are welded on the inner side of the thin steel plate. The fixed rods are arranged close to the outer contour of the thin steel plate. Long screws and short screws are evenly welded in the longitudinal and transverse directions in the area surrounded by the fixed rods on the inner side of the thin steel plate.
