SSHO, SSHZ pit furnaces

 SSHO pit furnacesfor heat treatment (quenching, annealing, drying, brazing, melting, baking) of various products under air atmosphere at a temperature of up to1250 °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 catalystwhen 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 ona 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 easilyassembled within one day.Original block design allow us tomake the installation andmaintenance 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 preventingfrom concequences of breakage and short-circuits.

Thefurnaces are certificated and complied with terms of reference 3442.010.24662585-04 (statement of compliance#ROSS RU.42.00036 f 26.08.2011).
