All-purpose electric chamber furnace, SQ type with controlled atmosphere enables the application of modern technologies of heat and thermo-chemical treatment of charge within the range of temperatures 650-1000°C.

TECHNOLOGICAL PROCESSES:

• Gas carburizing at temperature from 850°C to 950°C,
• Gas carbonitriding at temperature from 780°C to 900°C,
• Heating before hardening at temperature from 780°C to 1000°C,
• Annealing at temperature from 650°C to 850°C

Heat or thermo-chemical treatment process is carried out in air-tight chamber, without any air access from outside. Inside the chamber there is forced atmosphere circulation within atmosphere mixer. By this way, it improves the uniformity of charge heating in the utilization area and provides contact of all its faces with an atmosphere and levels out the furnace composition over the entire volume of the furnace.

Hardening processes take place in the oil tank placed in front part of the plant. Charge can also be cooled in the upper part of furnace vestibule. Furnace power supply, mechanism control and process parameters control takes place by means of a control cabinet.

Chamber furnaces, SQ type, can work with other plants, forming process lines for thermo-chemical treatment:

Auxiliary equipment included in the line:

• Washing plants
• Chamber furnaces for high and low temperature tempering
• Mobile charge loaders
• Loading and unloading tables
• Atmosphere generators
