melting furnace

Abstract

The invention discloses a melting furnace. The melting furnace comprises a furnace body, wherein a pouring port is formed in a top of the furnace body and a furnace cover used for covering the pouring port is arranged at the top of the furnace body, a heater is arranged in the furnace body, a liquid outlet pipe is arranged at the bottom of the furnace body, and a drain valve is arranged on the liquid outlet pipe. The melting furnace further comprises two motors and two stirring paddles, wherein one end of each stirring paddle is driven to rotate by the corresponding motor, and the other end of the stirring paddle stretches in the furnace body; and the liquid outlet pipe is a double-layer spiral pipe, and comprises a slag storage pipe and a fluid pipe sleeving the outer side of the slag storage pipe, one end of the slag storage pipe communicates with the furnace body, meshes used for guiding molten metal in the slag storage pipe into the fluid pipe are formed in the other end of the slag storage pipe and the pipe wall of the slag storage pipe, a screen plate is further arranged on the inner wall of the slag storage pipe, and a plurality of screen holes used for sieving metal slag are formed in the screen plate. With the adoption of the melting furnace, the effective utilization rate of metal can be increased, and the metal slag is prevented from being mixed in the molten metal and cast.

Description

technical field [0001] The invention relates to the technical field of smelting, in particular to a melting furnace. Background technique [0002] The wheel hub is one of the most important safety parts on the car. It bears the pressure of the car, is affected by the dynamic torque of the car when starting and braking, and also bears the impact of the car turning, bumpy road, and road obstacles during driving. Irregular alternating stresses produced by dynamic loads in different directions. The production process of the wheel includes melting, casting, heat treatment, machining and other processes. The melting furnace is a kind of equipment used to melt metal in the melting process and plays an important role in actual production. After the metal is melted into a melt in the melting furnace, it needs to be taken out of the melting furnace before subsequent casting and other processes; the traditional method of taking out the molten metal is for workers to scoop it out with ...

AI Technical Summary

Problems solved by technology

[0004] However, the above-mentioned technical solution still has certain defects: in the process of melting the metal into a liquid state, due to the limited burning time, it is easy to cause some smaller particles of metal slag generated in the melting process to not be completely melted, so that the final molten metal still remains Some metal slag; this not only causes metal waste and reduces the effective utilization rate of metal, but also these granular metal slags follow the molten metal for casting and molding, which will reduce the strength and other properties of the formed casting
