Scientific transformation method of induction melting furnace
The furnace body of the induction melting furnace includes a furnace shell. The bottom of the furnace shell is provided with a furnace bottom plate and furnace bottom refractory bricks. The upper part of the furnace shell has a furnace mouth, a furnace mouth refractory brick, and a furnace panel fixedly connected with the furnace shell. The furnace shell is made of aluminum alloy, and the furnace floor and furnace mouth are made of cement asbestos board. The aluminum alloy has poor mechanical properties and poor high temperature resistance (melting point 700°C) and poor impact resistance, which makes the induction melting furnace body high in cost and short in service life. Cement asbestos boards are not resistant to impact, have very poor seismic performance, are easy to crack, fragile, and have a short service life. Generally, they must be replaced in about 2 months. In addition, furnace bottom refractory bricks and furnace mouth refractory bricks also have the disadvantage of high cost.
The purpose of the transformation is to overcome the above shortcomings and provide an improved induction melting furnace body.
The transformation provides a furnace body of an induction melting furnace, which includes a furnace nozzle and a furnace shell. The bottom of the furnace shell is provided with a furnace bottom plate and a furnace bottom refractory layer. The upper part of the furnace shell is provided with a furnace mouth plate, a furnace mouth refractory layer, and the furnace shell. The integrated furnace panel and the short and long screws and nuts connecting the furnace shell and the furnace body are characterized in that the furnace panel and the furnace mouth plate are made of alloy steel. Due to alloy steel
It has excellent mechanical properties, high temperature resistance, and a melting point of 1400°C. Therefore, the service life of the furnace panel of the induction melting furnace body is prolonged and the cost is reduced. It can be used for 3 to 5 years. The impact resistance and earthquake resistance of the furnace mouth plate are improved, not easy to be broken, not easy to crack, the service life is greatly extended, and the cost is greatly reduced.
The furnace shell and the furnace bottom plate are made of alloy steel, and the furnace mouth refractory layer and the furnace bottom refractory layer are prefabricated drawings of reinforced cement. The furnace shell and the furnace bottom plate are made of alloy steel, so that the service life of the furnace shell of the induction melting furnace body is prolonged, the cost is reduced, and it can be used for 3 to 5 years. Improve the impact resistance and earthquake resistance of the furnace floor, not easy to break, not easy to crack, and greatly extend the service life.
The cost is greatly reduced. The cost of the reinforced cement precast ring is lower, so use it to replace the furnace mouth refractory brick
Refractory bricks and furnace bottom can reduce the cost of induction melting furnace body.
The aforementioned alloy steel is an alloy steel with a manganese content greater than 8% and a chromium content less than 12%. The short and long screws and nuts connecting the furnace shell and the furnace body are made of stainless steel. The original short and long screws and nuts connecting the furnace shell and the furnace body are made of brass, and the cost of brass is higher than that of stainless steel.
The above-mentioned burner nozzle is formed by stainless steel welding and then built with furnace sand.
The transformation has the following characteristics:
The furnace panel and the furnace shell have a long service life and low cost. The furnace bottom plate and the furnace mouth plate have good impact resistance and seismic performance, not fragile, not easy to crack, long service life, low cost, reinforced cement prefabricated drawings and short and long stainless steel Both the screw and the nut have the characteristics of low cost. Therefore, the manufacturing cost of this transformation is greatly reduced.
The following describes the implementation side of the transformation in conjunction with the drawings:
Figure 1 is a schematic diagram of the top view structure of the transformation
Figure 2 is a cross-sectional view of Figure 1 along the A-A section
Refer to Figure 1 to Figure 2: The transformation includes the furnace nozzle 9 and the furnace shell 4. After the furnace nozzle 9 is formed by stainless steel welding, it is made of furnace building sand. The furnace shell 4 is made of alloy steel. The furnace shell 4 has a furnace bottom plate 6 and a furnace bottom refractory layer. The furnace bottom plate 6 is made of alloy steel. The furnace bottom refractory layer is a reinforced cement prefabricated ring. The furnace mouth plate 3, the furnace mouth refractory layer and the furnace panel welded and connected with the furnace shell are integrated, the furnace mouth plate 3 and the furnace panel 1 are made of alloy steel, and the furnace mouth refractory layer is a reinforced cement precast ring 20 Alloy steel has a manganese content greater than 8%. Alloy steel with a chromium content of less than 12%. The above-mentioned components in the furnace shell 4 are fixedly connected in the furnace shell 4 by a long screw 8 and a nut, and the furnace shell 4 is fixedly connected as a whole by a short screw 7 and the nut. The long and short screws 8, 7 and nuts are made of stainless steel.http://www.songdaokeji.com/plus/list.php?tid=49
