Description

Technical Field

[0001] This utility model relates to the field of casting processing technology, and in particular to a smelting device for metal casting production. Background Technology

[0002] Metal castings are metal products produced through a casting process. This involves pouring molten metal into a mold or model, allowing it to cool and solidify to form the desired shape. Metal casting production requires melting the metal blocks, which necessitates the use of a melting device. While current casting melting devices meet basic usage requirements, they still have shortcomings in practical application. For example, current devices are inconvenient for treating fumes during the melting process, leading to air pollution. Furthermore, the high temperature of the fumes, if directly emitted, can raise the temperature in the production workshop, making long-term operation unsuitable for workers. Therefore, improvements are needed. This paper proposes a melting device for metal casting production. Utility Model Content
