Vertical two-chamber vacuum furnace for hardening products in oil-cooled gas

appointment

 
Vertical two-chamber vacuum furnace designed to harden in oil products alloyed structural steel, high speed steel, high-strength steel, M300 steel, in particular for the hardening under vacuum rods, panels, long shafts, aircraft landing gear or similar components easily deforming in effective termoobrabotke.Otlichnoe cooling minimizes liner dlinnyhs parts, improving the quality properties of the structure.

Technical features vertical vacuum furnace for tempering

1.Vertikalnaya two-part design, the customer can choose a vertical movable structure and location in accordance with their requirements.
2.Modulnaya optimized furnace chamber design, with a good temperature uniformity.
3.Regulirovka cages speed linear motion in the "slow-fast-slow." Stability, reliability and shorter travel time.
4.Produvanie shielding gas during the quenching oil medium to minimize evaporation acceleration and oil vapor cooling
5. Vertical dual-chamber vacuum furnace equipped with a large capacity tank for oil, hot oil is cooled by an external heat exchanger and circulation pump for better cooling.
6.Two oil cooling type: paddle mixing and spray nozzles are used for different sizes of parts. Minimally long lead items
7.Bolshaya cage and high efficiency, especially for hardening under vacuum landing gear oil brand staliM300 and other long items.
