Melting device for metal casting based on liquid level equal altitude

Abstract

The invention provides a melting device for metal casting based on liquid level equal altitude, and relates to the technical field of metal castings. The melting device for metal casting based on theliquid level equal altitude comprises a furnace body, and a crucible is fixedly installed in the furnace body; a feeding port is formed between the furnace body and the right end of the crucible; a coil is wound in the furnace body; a first lifting rod is connected in the crucible in a sliding manner; a pipeline is formed on the left side of the crucible; and a second lifting rod is connected in the pipeline in a sliding manner. Due to the melting device for metal casting based on liquid level equal altitude, the degree of melting can be known about in real time, metal liquid is discharged intime after complete melting, and therefore energy waste caused by overtime smelting is avoided, and the phenomenon that the heat loss is caused due to the fact that a furnace cover needs to be openedis avoided; and energy saving is better and efficiency is higher, it is not needed to take the crucible when the metal liquid is collected, the smelting process can be continuously performed easily, and more time and labor are saved.

Description

technical field [0001] The invention relates to the technical field of metal castings, in particular to a melting device for metal casting based on liquid level contours. Background technique [0002] Metal casting is the process of smelting metal into a liquid that meets certain requirements and pouring it into a mold. After cooling, solidification, and cleaning, a casting with a predetermined shape, size and performance is obtained. The casting blank is almost formed. The purpose of free machining or a small amount of machining, reducing costs and reducing time to a certain extent, is one of the basic processes of the modern machinery manufacturing industry. [0003] The first step in casting is to melt the metal into a liquid. The crucible furnace is a kind of melting equipment. The alloy is melted in the crucible and will not come into contact with the burning material, so the chemical composition of the alloy is hardly affected by the furnace gas. , the temperature of ...

Problems solved by technology

[0003] The first step in casting is to melt the metal into a liquid. The crucible furnace is a kind of melting equipment. The alloy is melted in the crucible and will not come into contact with the burning material, so the chemical composition of the alloy is hardly affected by the furnace gas. , the temperature of the alloy liquid is also relatively uniform, but during the melting process, the crucible furnace is in a closed state, and it is impossible to know the degree of metal melting in time. If the melting time is too long, it will easily cause waste of energy. When the furnace cover is opened for observation, It will also cause heat loss, which reduces the efficiency of smelting, and the traditional crucible furnace needs to take out the crucible after the smelting is completed, and continuous smelting cannot be carried out, and the operation is complicated and laborious
