Precise Technology Vacuum Directional Solidification Furnace With
Iron - based For Biomedicine
I. Overview
This series of vacuum directional solidification 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 production of directional solidified and single-crystal
parts by pulling down mechanism. It can strictly control
temperature and alloy content of materials.
This furnace 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.
