Magnesium alloy chip vacuum frit system

Abstract

The invention discloses a magnesium alloy chip vacuum frit system. The magnesium alloy chip vacuum frit system comprises a vacuum furnace, a material pushing mechanism, a protective gas set, a vacuumunit, a condensing mechanism and a control cabinet. The material pushing mechanism is arranged above the vacuum furnace and comprises a driving unit and a material pushing rod, and the driving unit drives the material pushing rod to move up and down, so that the material pushing rod penetrates through an upper cover of the vacuum furnace and enters the vacuum furnace; the condensing mechanism is arranged between the vacuum furnace and the vacuum unit and is correspondingly connected with the vacuum unit and the vacuum furnace through pipelines; the protective gas set is connected with the vacuum furnace through a pipeline; and the control cabinet is electrically connected with the vacuum furnace, the material pushing mechanism, the vacuum unit and the condensing mechanism. According to thesystem, by applying the technical scheme, the magnesium chips can be recovered online, the risk caused by accumulation of the magnesium chips is reduced, and the recovery rate of the magnesium chipsis increased.

Description

technical field [0001] The present application relates to the technical field of metal melting and casting, and more specifically, relates to a vacuum frit system of magnesium alloy chips. Background technique [0002] As the lightest metal structural material, magnesium alloy has been widely used in transportation, household electronics, power tools, aerospace and military supporting fields in the past decade. As a new material industry, the primary requirement for the industrialization of magnesium alloys is the continuous R&D and manufacturing capabilities of manufacturing equipment. From 2000 to 2015, China's magnesium alloy die-casting enterprises have gradually developed from zero to nearly 300. Die-casting equipment has also experienced a process from relying entirely on imports to localization and then to customized research and development for industry needs. With the lightweight of automobiles, With the advancement of electric vehicles and rail transit, it is expe...

Problems solved by technology

Since most of the magnesium chips produced during the cutting process of magnesium alloys are unoxidized magnesium and magnesium alloys, the nature of metal magnesium is lively, and it is a first-class flammable product when it is wet. The ignition point and minimum ignition energy are low, and the chips are thin and small. , the specific surface area is large, so it is easy to burn in the air under high temperature environment, and the storage risk is high

However, the magnesium scrap recovery systems provided by existing equipment manufacturers are all large-scale equipment, which are only suitable for specific recycling foundries, and cannot recycle magnesium scraps generated by daily magnesium alloy machining on-line, resulting in a large safety risk caused by the accumulation of magnesium scraps. At the same time, due to the large specific surface area of ​​magnesium chips, it will be in contact with air for a long time, so that the degree of oxidation will be high and the recovery rate will be reduced.
