SSHO, SSHZ pit furnaces
SSHO pit furnaces for heat treatment (quenching, annealing, drying, brazing, melting, baking) of various products under air atmosphere at a temperature of up to 1250 °C.
SSHZ furnaces are multy-purpose complexes for all most popular methods of heat treatment and surface impregnation:
- carbonization,
- carbonitriding,
- nitriding,
- heating for quenching under shielding atmosphere,
- annealing,
- austenization and so on.
The furnaces are equipped by built-in independent endogenerator unit. We use NIAP-10-01 as a catalyst when producing endothermic gas atmosphere. Such catalyst allow us to made the heat treatment process more stable.
SSHZ furnaces have a secondary gas feeding system to control a carbon potential, depending on a type of surface impregnation and a sort of metal processed.
Working chambers of SSHO and SSHZ furnaces are made of modern high-performance fireproof materials. The furnaces are delivered as the lined modules, which can be easily assembled within one day. Original block design allow us to make the installation and maintenance procedures quick and easy.
Control system is based on a modern MBU series controller (made by MIUS). Control system continously diagnoses the power circuits, protecting the heating spirals from overheating, blowing-out and preventing from concequences of breakage and short-circuits.
The furnaces are certificated and complied with terms of reference 3442.010.24662585-04 (statement of compliance #ROSS RU.МТ42.Н00036 оf 26.08.2011).
