VCTF Serie is widely used in in the manufacturing of ceramics, optical materials, carbon composite materials, cemented carbide, powder metallurgy sintering under high temperature and vacuum condition with an option for gas protection if required.

 

Structure

 

  • Chamber:Double-Layered Water Interlayer structure, inner layer with polished stainless steel(1Cr18N9Ti), and with an outer layer of carbon steel. The upper and lower flanges are welded into a cylindrical structure. Vacuum sealed with "O" ring with water cooling.

  • Vacuum System: One diffusion pump with cold trap and one Mechanical pump

  • Temperature Control SystemEurotherm 3504 Controller,500 Segment temperature control with P.I.D

  • Gas FlowOne air inlet and one air outlet, Gas controlled atmosphere.

  • Water-Cooling SystemBuilt-in alarm and safety feature to cut off power in the event of a loss in water flow.

  • Heating Elements and Heat ShieldsThe heating elements are made of electrode graphite and machined into a cylindrical structure,The heat shield is 80 mm thick, and composed of stainless steel, carbon felt, graphite cylinder. The heat shield provides thermal insulation, uniform heating, large radiation surface, as well as thermal shock resistance.
