Kirov Mayak Plant (part of the Kalashnikov concern) is modernizing the thermal production area. The company has commissioned 2 shaft furnaces, and commissioning works have been completed on 2 more vacuum furnaces. This was reported by the press service of the concern.
The plant's employees thermally treated parts for tool production in shaft furnaces, and parts made of high-alloy stainless steel grades — in vacuum furnaces. The processed components do not require subsequent cleaning.
How do vacuum and shaft furnaces work?
Heat treatment — the process of heating and cooling a metal or alloy. When heated, it is calcined to the desired temperature, then kept in a heated state for some time. Thus, heat is evenly distributed throughout the metal, improving its physical and mechanical properties.
Shaft furnaces operate on the principle of countercurrent, when the material passes through the zones of drying, heating, firing and cooling, being washed by a countercurrent of gas. In vacuum furnaces, parts are processed in a vacuum to prevent undesirable chemical reactions such as oxidation and nitriding.
The press service of the concern stated that the new furnaces will soon reach their design capacity. This will allow Mayak to increase the volume of parts processing.
Kirov Mayak Plant serially produces civilian and military products, including a launcher for completing the 9K111 "Fagot" and 9M113 "Konkurs" ATGM. These systems have already proven their effectiveness in real combat operations.
