Vcuum melt spun furnace for producing thin narrow metallic flakes/ribbons

Specification:

Description:

This complete set of vacuum spinning machine is made up of melt-spinning chamber (including furnace body, inspection window, inert gas filling entrance, dust filter, imported metal molybdenum wheel, melt-spinning axle), sensor (including induction coil and 2 sets of crucible), cooling chamber, UPS, middle frequency power supply introduction mechanism which includes imported cooling water cable, melting crucible rotating mechanism, secondary feeding mechanism, water cooling system, middle frequency power supply, vacuum system, operation and control system.

Main technical parameter:

Smelting material: NdFeB alloy ingot

Flow rate: standard for 1.5kg/min. limitation for 2.5kg/min

Melting temperature: general at 1350 , limitation at 1500.

Melting system: IGBT power, the melting power is over 250kw and takes about 40 minutes from power on to totally melt. (calculating by melting 100kg pure iron)

Vacuum system: utimate vacuum ≤ 1mTorr (empty furnace fully degassing, working vacuum:10mTorr       

Secondary system can load 50kg ingot with diameter below 200mm.

Cooling system:the cooling chamber has vibration cooling function which can cool from the temperature 700 to 60 within 2 minutes.    

Applications:

The vacuum melt-spinning furnace is under the vacuum or non- vacuum conditions to smelt metals such as Fe-based alloy, Ni-based alloy. Under the non-vacuum state, pour the liquid metals on the surface of the high-speed rotating cooled roll, the rotating cooled roll throwing and hitting the metals into thin ribbon material.

Core equipment for bonded magnet sheet mainly used for intermediate products of magnetic powder:

13-9, 14-12, 15-7, 16-10.

Competitive Advantage:

Adopt middle frequency induction principal which is of quick heating speed, little burning loss, low labor strength as well as good quality.

Furnace body adopts optimum material which can enhance the use-life time.

Melting pot inspection window, thermal-preservation pot inspection window and nozzle inspection window provide a real-time and quick view on the furnace operation.

Adopt UPS for wheel quits in case of power failure.

Full leak detection system ensures safety during the whole process.

Adopt inert gas Argon or Nitrogen for gas protection to ensure the safety of the equipment as well as operators.

The melting crucible rotating mechanism adopts servo motor driven which quicken the rotating speed.
