Vacuum furnaces are used for sintering and annealing products from a variety of materials and alloys: magnetic rare earth elements, hydrogen storage alloys, easily oxidized and refractory metals, other types of heat treatment, in the sintering of Sm-Co, AlNiCo powders, metal powders, carbides, ceramic materials, photovoltaic coating materials, magnetic materials and rare earth refractory metals, W, Mo, W-Cu based alloys, cleaning of
graphite products.

Characteristics :  

Description:
The design of these furnaces is based on international experience in the manufacture of this equipment and its multiple upgrades during operation. The furnaces use advanced methods of protective atmosphere circulation: external and internal, high-performance vacuum pumps are used. Furnaces have an adjustable cooling rate, high uniformity of temperature distribution, quickly reach the operating mode. The temperature in the ovens is reliably controlled and their advantages are high pumping speed and low leakage. Models of furnaces of this series are divided into two types: furnaces with internal (KUEH) and external (RUE) circulation of the protective atmosphere. 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. When designing this series of ovens, our designers paid special attention to ease of maintenance, reduced energy consumption, environmental protection and increased productivity.
