The further technical proposal is that a switch of the blower is connected with a handle on a furnace cover of the normalizing furnace through a tight connecting rope. After the steel member is heated to a temperature of 30-50 ℃ above Ac3, the furnace cover is opened after the steel member is kept warm for a period of time, and meanwhile, a switch of the air blower is turned on, so that cooling and heat dissipation are realized, the cooling speed is higher during normalizing, and the operation is simplified. The positions of the bottom wall of the furnace body except the air port communicated with the air pipe are not provided with refractory bricks, and the other positions of the bottom wall of the furnace body are paved with refractory bricks.

The further technical proposal is that the bottom wall in the furnace body is provided with refractory bricks, and the bracket is arranged above the refractory bricks; the support is triangular, the support is formed by fixedly connecting three square tubes, and three corners of the support are fixedly connected with tubular heightening blocks. Thus, after the product to be normalized is placed on the support, the product (namely, the transmission device of the generator set) is cushioned, and the heat dissipation effect is achieved (because the air pipe of the air blower is arranged below the bottom wall of the furnace body).

The further technical proposal is that the cross section of the square tube is in the shape of a square with the side length of 60mm, and the wall thickness of the square tube is 5 mm.

A further technical scheme is that the inner side wall of the furnace body is provided with a circle of heat preservation cotton, the inner side wall of the furnace body is fixedly provided with a plurality of fixing pins for winding electric heating wires, and the length of each fixing pin is larger than the thickness of the heat preservation cotton. Set up the cotton effect that has played the maximize and reduced the heat and outwards conduct heat through the furnace body lateral wall of back like this to the fixed pin surpasss the cotton setting of heat preservation and makes the electric heating wire of coiling be located and keep away from the heat preservation cotton and be closer to the furnace body inner chamber, and the heating is more pointed.

The further technical scheme is that the fixing pins are provided with a plurality of circles and the fixing pins of the upper and lower adjacent circles are arranged in a staggered mode. Adjacent circle dislocation set makes the cotton installation of heat preservation back closely laminating mutually not hard up about the fixed pin, guarantees the cotton heat preservation effect of heat preservation.

The further technical scheme is that the fixing pin is arranged at the middle lower part of the inner side wall of the furnace body, and a circle of heat preservation cotton installation guide pin is fixedly arranged at the middle upper part of the inner side wall of the furnace body. Considering that heat transfer only sets up in furnace body inside wall lower part, upper portion still sets up the cotton installation uide pin that keeps warm in the furnace body inside wall, and the cotton installation uide pin that keeps warm is from top to bottom or by the furnace body middle part to the installation of furnace body side wall along adjacent the cotton installation of keeping warm when being convenient for make the cotton closely support of keeping warm to guarantee to keep warm and almost seamless after cotton installation, increase the heat preservation effect.

The utility model has the advantages and the beneficial effects that: after the steel member is heated to a temperature of 30-50 ℃ above Ac3, the furnace cover is opened after the steel member is kept warm for a period of time, and meanwhile, a switch of the air blower is turned on, so that cooling and heat dissipation are realized, the cooling speed is higher during normalizing, and the operation is simplified. After the product to be normalized is placed on the support, the product (namely, the transmission device of the generator set) is cushioned, and the heat dissipation effect is achieved (because the air pipe of the air blower is arranged below the bottom wall of the furnace body). The heat preservation cotton plays the maximize and has reduced the outside effect of conducting heat of heat through the furnace body lateral wall to the fixed pin surpasss the cotton setting of heat preservation and makes the electric heating wire of coiling be located and keep away from the heat preservation cotton and be closer to the furnace body inner chamber, and the heating is more pointed. Adjacent circle dislocation set makes the cotton installation of heat preservation back closely laminating mutually not hard up about the fixed pin, guarantees the cotton heat preservation effect of heat preservation. Considering that heat transfer only sets up in furnace body inside wall lower part, upper portion still sets up the cotton installation uide pin that keeps warm in the furnace body inside wall, and the cotton installation uide pin that keeps warm is from top to bottom or by the furnace body middle part to the installation of furnace body side wall along adjacent the cotton installation of keeping warm when being convenient for make the cotton closely support of keeping warm to guarantee to keep warm and almost seamless after cotton installation, increase the heat preservation effect. The normalizing heat treatment of the transmission device of the wind generating set is changed from the prior door-opening type box-type furnace to the prior well-type furnace, so that the space of a workshop can be saved, the prior natural gas or fuel oil burning heating mode is changed into the heating wire electric heating mode, the energy can be saved, the temperature is well controlled, and the product quality can be better ensured.
