Furthermore, the sillimanite hooks are of an I-shaped structure, two adjacent sillimanite hooks form a bearing groove, and the sillimanite cover plate is arranged in the bearing groove.
Further, the height of the light heat-insulating cotton is lower than that of the sillimanite hook.
Further, the light heat-insulating cotton is aluminum silicate light heat-insulating cotton.
Further, the steel member comprises I-steel and square steel fixedly connected to the bottom end of the I-steel, the I-steel and the square steel are arranged in a grid shape, L-shaped angle steel is fixedly connected to two sides of the square steel, clamping grooves are formed in the opposite arrangement of the L-shaped angle steel on two sides of the square steel, and the sillimanite hooks are hung in the clamping grooves.
Further, the height of the sillimanite cover plate is 1.5cm-2.5cm, and the height of the light heat-insulating cotton is 37.5cm-38.5cm.
In summary, the utility model has the following advantages: the existing high-alumina brick is replaced by the sillimanite hook, the sillimanite cover plate with the height of 1.5cm-2.5cm and the light heat-insulating cotton with the height of 37.5cm-38.5cm, so that the original weight is greatly reduced, the heat insulation of the interior of the electric melting furnace is ensured during normal electric melting of the electric melting furnace, and the ineffective energy consumption is reduced.
