Problems solved by technology

When using the furnace mouth 1 of the electric furnace to pour molten iron, since the shape of the iron nozzle is linear, when the electric furnace starts to tip over, the range of the molten metal drop point is relatively too large. If the molten metal is poured all at once, it will cause serious splashing; Multiple overturning at a slow speed is adopted, because the demand for molten metal is small, resulting in a severe drop in temperature, which in turn affects the pouring quality

Embodiment Construction

[0010] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0011] Such as figure 2 As shown, the present invention includes an electric furnace body 2 and an electric furnace nozzle 3 connected to the electric furnace body 2. The electric furnace nozzle 3 adopts an arc-shaped structure, and it is composed of a furnace nozzle connection end 4 and an outlet integrally formed with the furnace nozzle connection end 4. Liquid port 5 constitutes. The connecting end 4 of the furnace nozzle and the electric furnace body 2 are connected in an inclined manner, so that the area of ​​the connecting end 4 of the furnace nozzle is increased, and the molten metal in the electric furnace body 2 can be poured out in a larger amount.

[0012] In the above-mentioned embodiment, the liquid outlet 5 of the circuit furnace nozzle 3 adopts a circular arc surface, so that when the electric furnace body 2 dumps the molten metal, th...

Abstract

The invention relates to a medium frequency electric furnace mouth and is characterized by comprising an electric furnace main body and an electric furnace mouth connected with the electric furnace main body, wherein the electric furnace mouth adopts an arc structure and consists of a furnace mouth connecting end and an liquid outlet; and the liquid outlet is formed with the furnace mouth connecting end integrally. In the medium frequency electric furnace mouth, the arc structured electric furnace mouth is adopted, so that the operation of an electric furnace operator is more convenient; and in real fixed-point casting, the medium frequency electric furnace mouth accelerates the casting speed, reduces the temperature reduction of liquid iron so as to improve the pipe casting efficiency, save electric power cost and simultaneously avoid safety incident caused by metal liquid splashing. The medium frequency electric furnace mouth can be widely applied in production equipment in foundry industry.

Description

technical field [0001] The invention relates to an electric furnace component in casting production equipment, in particular to an intermediate frequency electric furnace nozzle used for melting and heat preservation molten metal in an intermediate frequency electric furnace during pouring. Background technique [0002] In the foundry industry, when the intermediate frequency electric furnace is used as the heat preservation bag, the molten metal is poured into the quantitative pouring bag, and the product molding process is carried out, the furnace mouth is required to pour the molten metal. At present, the nozzle of the intermediate frequency electric furnace used is the nozzle with the structure of the manufacturer's equipment, such as figure 1 As shown, the electric furnace nozzle 1 adopts a linear structure. At the connection with the electric furnace body 2, one end of the electric furnace nozzle 1 is connected to the circuit body 2 in a vertical direction, and the oth...
