VACCUM MELTING APPARATUS FOR LIGHT METAL AND VACUUM MELTING METHOD USING THE SAME

摘要

The present invention relates to a light metal vacuum melting apparatus and a vacuum melting method, and more particularly, by melting light metal raw materials very effectively in a high vacuum state, high melting efficiency, gas (bubble) removing efficiency, etc., as well as generating high quality molten metal. It relates to a light metal vacuum melting apparatus and a vacuum melting method using the same.;Vacuum melting apparatus of the present invention, the vacuum melting chamber is provided with an air discharge pipe on the upper side; Melting furnace formed in a pipe shape of a predetermined length, one end is inclined at a predetermined angle to one side of the vacuum melting chamber; A plurality of heating units arranged in a line along an outer circumferential surface of the melting furnace; A stopper disposed at an inner diameter of the melting furnace and having a plurality of molten through holes; A material input pipe connected to the other end of the melting furnace and having an air discharge pipe at one side thereof; First and second vacuum valves respectively installed at both ends of the material input pipe; A first molten metal heat insulating tube communicating with the other side of the vacuum melting chamber; And a second molten metal heat insulating tube communicating with the first molten metal heat insulating tube.;Light metal, vacuum, melting, molten metal, chamber, heating unit
