Furnaces for vacuum nitriding

Furnaces for vacuum nitriding

Vacuum nitriding is a heat treatment process in which nitrogen atoms diffuse into the metal surface, creating a surface hardening of the material.
Characteristics :

Maximum temperature in the working chamber, °C  720   
Temperature uniformity, °C  ±5   
Leakage rate (in a cold empty vacuum furnace), Pa/h   0.5
Ultimate vacuum, Pa (in a cold empty furnace)       6.7×10 -1   
Working area, (WxHxD), mm   from 250x250x400 to 800x800x1200 
Maximum mass of a load at a time, kg  1200 


Description:
This process is most commonly used for case hardening of low carbon and low alloy steels, however it can also be used to harden medium and high carbon steels, titanium, aluminum and molybdenum. Typical applications for this series of furnaces include the production of gears, crankshafts, camshafts, cam followers, valve parts, extruder screws, injection molding tools, forging dies, dies, firearm parts, injectors and other mold components.
 

Design features and equipment:

 

  •      Water cooling of the furnace body and door, current leads and cooling gas circulation pipes.
  •      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.

  •      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, an increased working area according to the technical specifications of the customer.
