High-temperature vacuum furnaces for brazing are used in industries for soldering copper alloys, stainless steels, heat-resistant and heat-resistant alloys.

Characteristics :

Description:
This equipment is used in the process of vacuum brazing of refractory alloys and dissimilar alloys, which include Ti, Zr, Nb, Mo. The method is widely used in the production of heat exchangers, diamond cutting tools, Fe-Cr-Al alloys, plate heat exchangers, oil heat exchangers.
The brazing process takes place in a vacuum or protective atmosphere. As a result, there is no oxidation of the parts, deformations of the connected products are minimized, there is no porosity in the resulting joint, no flux is required, the weld surface has a good appearance, and there is no environmental pollution. The furnaces are controlled by a programmable logic controller. The temperature in the furnaces is maintained with high precision by a separate controller. Furnaces have a high level of automation. During operation, the operator can safely switch from automatic to manual control mode, the furnaces are provided with an emergency warning system. Furnaces are easy to set up, operate and maintain.

Design features and equipment:

•      Water cooling of the furnace body and door, current leads and cooling gas circulation pipes. Gas cooling system with powerful fan and water heat exchanger.
•      Heating chamber of square or round section.
•      Thermal insulation and heaters made of graphite, molybdenum or tungsten.
•      Autoclave type oven door with pneumatic blocking.
•      Sealed connector for connecting up to 12 thermocouples in the furnace.
•      A large set of additional components at the discretion of the customer.
•      Light and sound signaling of violations in the operation of furnace systems with display.

•      Vacuum - Edwards, England or Laybold, Germany. Included in the State Register of Measuring Instruments of the Russian Federation.
•      Controller - Siemens, Germany.
•      Temperature control - thermocouples made in Russia, Included in the State Register of Measuring Instruments of the Russian Federation
•      "Bookcase" for placing parts in a furnace made of molybdenum or heat-resistant alloy.
•      Loading "table" for laying (unloading) parts on (s) "shelf(s).
•      Transport trolley for loading (unloading) the "shelf" with parts into the oven (from the oven).

Note:
Characteristics are indicated for standard models, we offer furnaces with non-standard dimensions, increased working force zone according to the technical specifications of the customer.
