Thermal treatment
Our company proposes a wide range of thermal treatment of metal pieces of various shapes and design performed in chamber furnaces and in batch-type resistance furnaces.
Thermal treatment alters metal properties in order to meet specific production needs.
Most commonly thermal treatment improves stability of workpieces subject to extreme loads and require impact strength.

High temperature (800-950°C) and continuous exposure time (from few hours to few full days) enable carbon to penetrate the outer layer of the metal and thus generate iron carbides that improve robustness and durability of a piece. Gas cementing has a number of benefits compared with other method of chemical and thermal treatment. Firstofall, itensures homogenous carbon saturation on the entire piece surface enabling to obtain higher hardness and durability without any cracks or pores whatsoever. Secondly, this method decreases treatment time and energy costs alike.

These processes improve metal properties, namely strength, hardness and impact strength. Annealing relieves stress in metal and improve its plasticity. One of the key benefits of annealing in batch-type furnaces is more accurate control of temperature and heating time. These efforts ensure production of better quality and more reliable pieces with required characteristics. Moreover,batch-type furnace can be more convenient and efficient than other annealing facilities.

Apart from that, production capacities may benefit from shaft and chamber furnaces for metal treatment. Such furnaces may heat up metal to reach high temperatures and then cool it down. Metal is treated in shaft and chamber furnaces at high temperatures enabling to reach high hardness and strength of metal.

For production purposes, UHF-brazing is used to connect pieces from different metals and alloys. This brazing technique enables to produce a stiff and leak-proof connection that is highly resistive to corrosion and mechanical stress. UHF-brazing involves specific facilities that ensure accurate control of heating temperature and brazing time. The final product demonstrated high quality and reliability that does not require additional treatment. This type of thermal treatment enables to produce high quality and robust couplings fit to withstand high stresses and temperature.

Types of furnaces
Shaft furnace
Highly efficient for treatment of large pieces. The furnace is used for annealing, tempering, quenching, stabilization of non-ferrous metals.
Vacuum furnace
Ensures highly accurate treatment of copper, construction steel, titanium alloys
Batch-type bell furnace
This type of furnace is fit for homogeneous heating, leak proofness and quick replacement of treated pieces. As long as there are no dusty materials inside the chamber, and considering the new method to treat surfaces enable to perform extra-high purity processes.
