Description

Technical Field

[0001] The utility model relates to the technical field of magnesium alloy melting furnaces, in particular to a magnesium alloy melting furnace with a cleaning function. Background Art

[0002] A magnesium alloy melting furnace is a device used to melt and process magnesium alloys, which is widely used in the process of magnesium alloy casting and production. Due to its light weight, high strength and good mechanical properties, magnesium alloys are widely used in the fields of aerospace, automotive and electronic products, etc. The main characteristics of magnesium alloy melting furnaces include: high temperature tolerance, fire and explosion prevention design, atmosphere control, temperature control, automation and monitoring, etc. Magnesium alloy melting furnaces include arc melting furnaces, induction melting furnaces and resistance melting furnaces. Magnesium alloy melting furnaces play an important role in modern manufacturing. Through effective smelting and processing, the quality and performance of magnesium alloy products can be ensured to meet the needs of various industrial applications.

[0003] However, during the actual use of magnesium alloy melting furnaces, a certain amount of slag will be generated. Some of these slags will precipitate at the bottom of the furnace body, and some will float on the surface of the solution in the furnace body. In order to clean these slags, a cleaning device is generally set on the furnace body, and the slags are cleaned by using a filter screen to fish them. However, this cleaning method not only has a relatively slow cleaning speed, resulting in a long cleaning time, but also cannot effectively clean the slags precipitated at the bottom of the furnace body.
