Product introduction

  Application and Principles
  This series of vacuum directional solidifying furnace is a modern equipment working for melting metal or alloy with medium-frequency induction heating under vacuum,forming thermal gradient with specialized-designing holding furnace and cooling system,and preparation for directional solidified and single-crystal parts by pulling down mechanism.It can strictly control the temperature and alloy content of materials.
  Its furnace possesses the function of fast melting,minimizing the melting loss of elements.
  To obtain highest temperature gradient and smooth solidifying interface,it is adopted with special designing to its requirement for temperature gradient.
  This equipment is primarily applied to the production of silver-based,nickel-based,iron-based,and cobalt-based high-temperature alloys,and the high-quality products made of these alloys are commonly practiced into aerospace turbine engine industry,vehicle,bio-medical field,chemistry field and entertaining fields.Holding furnace can be designed as two-stage or three-stage structure.And its cooling stage can be designed as water jacket or liquefied metal with low melting point.
