Horizontal two-chamber vacuum furnace for hardening products in the oil and gas-cooled

appointment

 
Horizontal two-chamber vacuum furnace is designed for heat treatment of products of alloy structural steel, bearing steel, spring steel, steel stamping, high-speed steel and other. It allows the following process steps: tempering of products in the oil in a vacuum condition, cooling the product gas stream, bright high-temperature annealing in vacuum condition products, rental high temperature in vacuum condition and others.

Technical features

1. Vacuum tempering furnace products is a horizontal two-chamber structure, with a compact overall layout, efficiently and ergonomically.
2.Pod furnace design perfect octagonal shape, with a good temperature uniformity.
3.Unikalnaya technology beskeramicheskoy heaters with insulation. The persistence of more than 5 years without fear of reducing the quality of the thermal insulation.
4.Vnutrennyaya truck cages are moved by device type imposed by stretching ??, speed is regulated by frequency in the "slow-fast-slow" in a linear motion, stability, reliability and travel time korotko.
5.Vnutrenny cooling coil with uniform flow and high flow air circulation to get good cooling result.
6. Horizontal two-chamber vacuum furnace equipped with a large capacity for oil, hot oil is cooled with high speed external circulating heat exchanger by external circuit pump.
7.Dva cooling type, paddle mixing oil and spray nozzles used for various sizes of parts, minimizing their deformirovaniya.
8.Bolshaya cage and high efficiency compared with other similar ovens.
