Induction Melting Cold Crucible System for Preparation of High Melting Point Active Metal Powder

Abstract

The invention belongs to the field of melting equipment such as cold crucibles, and particularly relates to an induction melting cold crucible system for the preparation of active metal powder with a high melting point. The induction melting cold crucible system comprises a cold crucible petal (1), a cold crucible base (2), a copper finger (4), a water segregator (5), a base flange (6), a backwater seat (7) and an inductor (8); the inductor (8) is arranged on the outer side of the cold crucible petal (1); a circular cooling medium cavity (601) is horizontally formed in the base flange (6); a backwater channel (602) is longitudinally arranged in the middle area of the base flange (6); the backwater seat (7) is arranged at the lower part of the base flange (6); the water segregator (5) includes a water pipe (501), a backwater cap (502) and a flange (503); the water pipe (501) is longitudinally inserted into the inner chamber of the cold crucible petal (1); the bottom of the cold crucible petal (1) is fixedly connected with the water segregator (5) through the copper finger (4). The induction melting cold crucible system for the preparation of active metal powder with the high melting point is characterized by small energy loss, and effectively prevents the pollution of furnace burden by a heating source.

Description

technical field [0001] The invention belongs to the field of cold crucible smelting equipment, in particular to an induction melting cold crucible system for preparing high melting point active metal powder. The system is used for equipment under 30Kg. Background technique [0002] Induction smelting technology is an advanced smelting method, which removes the pollution of the furnace charge from the atmosphere and heating source during the smelting process. However, the general vacuum induction melting technology cannot prevent the reaction between the charge and the crucible, especially when smelting active metals or high-purity metals, this effect is very serious. At the end of last century, a more advanced cold crucible vacuum induction melting technology appeared. It is a method of vacuum induction melting using a water-cooled crucible (mainly pure copper, but also other alloys). This method can completely eliminate the pollution of the crucible to the charge.

Problems solved by technology

[0003] Although induction shell melting can melt high-purity active metals in a vacuum, it has not been widely used due to its complex structure and high manufacturing cost.
