Abstract
A kind of smelting in suspension cold-crucible, comprise cut into some lobes cylinder side wall and truncated cone-shaped bottom, be filled in the high temperature insulating material of intervalvular spaces and the induction coil of crucible periphery, it is characterized in that, described truncated cone-shaped bottom centre has a tapping hole, be provided with induction coil below described truncated cone-shaped bottom part down tapping hole, radius is greater than tapping hole radius, and described truncated cone-shaped bottom part down is sphere.Beneficial effect: have tapping hole and can be cast into difform ingot casting as requested, will cause ingot casting to pollute because of toppling over simultaneously.
Description
Technical field
The utility model relates to crucible technique field, especially a kind of smelting in suspension cold-crucible.
Background technology
Cold-crucible electromagnetic induction vacuum levitation melting method, it is a kind of method of smelting of develop rapidly in recent years, as long as be used for producing high-melting-point, highly purified refractory metal, many key areas such as prepare in metallurgical and high progress by material and be widely used, demonstrate good application prospect.
Cold-crucible electromagnetic induction vacuum smelting method is under vacuum by the metal of institute's melting or non-metal solid furnace charge, is placed in high frequency or intermediate frequency alternating electric field that induction coil formed, and utilizes the water-cooled metallic crucible of bucket as magnetic field.Make energy magnetic field energy concentrate on crucible volume space, and then form powerful vortex flow near furnace charge top layer, discharge Joule heat on the one hand and make load melting, form the Lorentz field of force on the other hand and make melt suspend (or half suspends) and stir.Due to maglev effect, melt and crucible internal walls are disengaged, and the heat radiation behavior between such melt and crucible changes into heat loss through radiation by heat loss through conduction, thus the main radiating rate in island is die-offed, the temperature making melt can reach very high, is suitable for melting refractory metal or its alloy.Prior aspect is: during melting, the suspension of furnace charge contacts brought pollution by effectively preventing furnace charge with sidewall of crucible, is suitable for and obtains high-purity or as lively as a cricket metal and nonmetallic materials.Moreover, cold-crucible is the suspension and the intensification that are controlled melt by the intermediate frequency in induction coil or high frequency electric, thus good control ability is likely realized, simultaneously induction heating method itself is a kind of non-contacting mode of heating, avoids the impact and volatilization that bring to crucible and metallic solution by the heating means such as beam-plasma, electron beam.But existing cold-crucible only can obtain the ingot casting of crucible interior shape.
Utility model content
In order to solve the deficiencies in the prior art, the utility model provides a kind of smelting in suspension cold-crucible:
A kind of smelting in suspension cold-crucible, comprise cut into some lobes cylinder side wall and truncated cone-shaped bottom, be filled in the high temperature insulating material of intervalvular spaces and the induction coil of crucible periphery, it is characterized in that, described truncated cone-shaped bottom centre has a tapping hole.
Further, be provided with induction coil below described truncated cone-shaped bottom part down tapping hole, radius is greater than tapping hole radius.
Further, described truncated cone-shaped bottom part down is sphere.
Beneficial effect: have tapping hole and can be cast into difform ingot casting as requested, will cause ingot casting to pollute because of toppling over simultaneously.
Accompanying drawing explanation
Fig. 1 is embodiment schematic diagram.
Detailed description of the invention
