Vacuum shaft-type furnace

Configuration:

  • Vacuum chamber body 8 m diameter;
  • High temperature lining;
  • Foot platform;
  • Vacuum system;
  • Pneumatic equipment;
  • Cooling water equipment;
  • Electric heaters;
  • Control system.

During production of welding constructions especially vacuum chambers it may observe an internal stress. It may destruct the welding area and led to leak appearance.

To avoid an internal stress appearance the vacuum shaft-type furnace was designed and developed. This furnace allows to make a high-temperature anneal a tempering of producing constructions. Maximum dimensions of cylindrical parts of vacuum chambers with diameter up to 6.5 m and height up to 4 m.

Vacuum chamber of furnace is a cylindrical body with lining material and zig-zag shaped nichrome heaters. The deck of furnace has ten shields made from heatproof steal. Work space of vacuum furnace has a twelve heating zone.

For temperature measurement in each zone used a thermo-electric transducers (thermocouples). To prevent damaging of lining the cast iron grinds was mounted on the floor.

Vacuum system is represented by two equal sets of vacuum pumping stations. One set includes one plunger pump with Roots pump and diffusion booster pump.

An advantage of thermal treatment in vacuum is an absence of oxidation, carbon deposits and other types of pollution on metal surface. It is not necessary to make a sandblast treatment, polishing or other type of cleaning.

It is not necessary to make a sandblast treatment, polishing or other type of cleaning. After baking process the metal parts deliver to finish treatment.
