Description
Technical Field
The utility model relates to a metal or alloy smelting device, in particular to a novel water-cooling copper crucible of a suspension ingot-drawing furnace.
Background
In the smelting technology, the vacuum induction smelting technology belongs to the more advanced and more common smelting technology, the smelting material is heated in an electromagnetic induction mode, the pollution of atmosphere on the smelting material is eliminated in a vacuum environment, and alloy products with higher purity can be prepared. However, crucible materials can contaminate the materials being melted during induction melting. The american BMI institute, g.h. schippereit et al, 1961, discovered that an electromagnetic field could enter a slotted copper crucible to heat the charge in the crucible. Thereafter, cold crucible induction melting technology was studied in the united states, germany, france, former soviet union, and the like. In order to prepare products and alloy materials which have high requirements on purity and are difficult to melt, a suspension melting technology, also called a cold crucible vacuum induction melting technology, appears at the end of the last century, and after the sixth international conference on steel in 1990, particularly in recent years, the cold crucible induction melting technology is developed more rapidly, and the main research progresses include: (1) the equipment scale is increased to a level close to the production requirement; (2) in addition to active metals and alloys, cold crucible induction melting technology has been applied to a wider range of material fields, such as superalloys and intermetallic compounds, high purity sputtering targets, refractory metals and alloys, oxide ceramics and gemstones, radioactive materials, polycrystalline silicon, high entropy alloys, and the like; (3) the technology is gradually combined with other modern material technologies, and a cold crucible electromagnetic continuous casting technology, a cold crucible directional solidification technology, a spray deposition technology and a chilling technology which use a cold crucible as an auxiliary device and the like are developed. The cold crucible vacuum induction melting technology adopts a copper crucible to replace a crucible made of a ceramic material of zirconium oxide and aluminum oxide, and an electromagnetic field enables molten furnace burden to be in a suspended or quasi-suspended state in the melting process, so that pollution of the crucible material to the melting material is eliminated. To prevent the copper crucible from being melted, the crucible needs to be cooled.
The vacuum suspension smelting equipment comprises a vacuum system, a cold crucible and a power supply system. Wherein the cold crucible and the power supply system (induction power supply) are the core of the technology. The cold crucible is required to be in a split type, each split is made of red copper with an independent water cooling system, the suspension effect of the melted materials is determined by the shape of the inner cavity of the crucible, the crucible is prevented from being damaged at ultrahigh temperature due to the special water path design, the power of a power supply is absorbed by the proper wall thickness in a minimized mode, and the use safety is ensured; the proper frequency of the power supply determines the suspension effect and the melting efficiency of the materials and ensures safe melting under vacuum.
At present, vacuum suspension smelting equipment can be widely applied to the preparation and smelting of high-quality metals or alloys with high purity, high melting point, oxidation resistance, pollution resistance and difficult uniform components, and belongs to the current advanced smelting equipment. The fine spherical metal powder is a main raw material for metal additive manufacturing (3D printing) and powder metallurgy, and the powder manufacturing technology with high performance and low cost promotes the continuous progress of the powder metallurgy technology, and becomes a very active leading-edge field for the research of material science and engineering technology at present. To produce a highly pure metal powder, whether using centrifugation or gas atomization, a high purity ingot is necessary. The suspension smelting process has specific advantages for smelting and purifying certain high-melting-point precious metal alloys, purifying and recovering rare earth metals and alloys thereof, and smelting certain pure and accurate metals or alloys required by scientific research, so that the suspension smelting process and ingot drawing are combined to manufacture high-purity alloy ingots with great prospect. However, the existing equipment has a plurality of defects and cannot meet the requirement of technical development.
At present, a common suspension crucible is a common overturning casting suspension crucible (shown in figure 4), a set of induction power supply load is responsible for melting and suspending, alloy is cast to a specified ingot mold by backward casting after melting is finished or the power of the induction power supply is slowly stopped, so that the alloy is solidified in the suspension crucible, and the bottom of the suspension crucible is not provided with a separate opening and is not provided with a bottom casting or ingot drawing function.
