Casting electric furnace good in stirring effect

Abstract

The invention discloses a casting electric furnace good in stirring effect. An electric furnace body, an electric heating wire, a stirring shaft and fan blades are included; a heat insulating plate isplaced at the bottom of the electric furnace body, and is placed at the groove bottom position of a rotating table; the rotating table wraps the electric furnace body; a tooth ring is welded and fixed to the bottom of the rotating table; a gear is engaged to the tooth ring; and a gear shaft is installed at the axis position of the gear through a key. The casting electric furnace good in stirringeffect is simple in structure, low in production cost and suitable for transformation on an existing electric furnace, the electric furnace body is made to rotate eccentrically, further sufficient blending of molten metal in the electric furnace body is effectively promoted in the rotating process, and the blending effect is greatly improved; the heat insulating plate avoids damaging and deformingof the tooth ring, the gear and other parts caused by high temperature; a spring A and a spring B have a good buffering shock absorbing effect, splashing leakage of the molten metal is avoided, the potential safety hazards are greatly lowered, and the casting electric furnace good in stirring effect is worthy of using and popularizing.

Description

technical field [0001] The invention relates to the technical field of casting equipment, in particular to an electric casting furnace with good stirring effect. Background technique [0002] Crucible furnace is the simplest melting equipment, mainly used for melting non-ferrous metals with low melting point, such as copper, aluminum and their alloys. In this kind of melting furnace, the alloy is melted in the crucible, and the heat is transferred to the charge through the crucible. The combustion products of the charge are not in direct contact, so the chemical composition of the alloy is hardly affected by the furnace gas, and the temperature of the alloy liquid is relatively uniform. Advantages: There are many models and specifications of the crucible furnace, and the application is not limited by the production scale, batch size and variety of smelting substances. It can be selected arbitrarily, has strong applicability, and can guarantee the purity of the smelted substa...

AI Technical Summary

Problems solved by technology

[0003] The crucible furnace is usually heated by electric heating. In the actual production process, the homogeneity of the alloy after melting is poor, and it needs to be stirred to obtain a good quality alloy metal liquid. However, in the prior art, the metal liquid is usually directly used by a stirring device Stir in the electric furnace, the molten metal is fully mixed at the position of the stirring fan blade, and the mixing effect of the molten metal at other positions is not good
