Vertical Type Bottom Loading Vacuum Gas Quenching Furnace Description：
Vertical gas quenching furnace is used for tool steel, die steel, high speed steel, stainless steel, ultra high strength steel, etc. It is especially suitable for large rods, discs and larger and heavier parts. Large shafts and plates are easily deformed. Metal heat treatment. The furnace has the characteristics of small footprint and compact structure.
Furnace structure is vertical single-chamber bottom loading.Customized structure is accepted.
Furnace bile designed basing on modular optimization, furnace temperature uniformity is good,cooling uniformity is good.
The bottom of the door lift transmission structure using ball screws, linear motion, never stuck, with protective cover to prevent dust pollution.
Lifting bracket equipped with automatic balance correction mechanism, automatically eliminate the cumulative error of lifting system. Lift smooth, no vibration.
Depending on the cooling requirements of different parts, you can choose a single heat exchanger furnace bile structure and two-stage, multi-stage heat exchanger furnace bile cooling structure.
Variable to the cooling technology, vertical spray cooling OR 360-degree circumferential cooling.
