Equipment for heat treatment allows to obtain a metal structure that provides high performance characteristics of products.
The production capabilities of the Instrument-Making Plant are provided with the following technologies:
| Types of heat treatment | Maximum working space, mm (temperature) electric furnace | Note |
| Heat treatment in high vacuum (up to 10 5 mm Hg) of all grades of steels and alloys, including those with the possibility of cooling with nitrogen high (up to 10 atm) pressure. Examples of heat treatment:
| 900 x 1200 x 700 (1320) | Minimal warpage, high surface quality |
| Oxidizing heat treatment of all steel grades, iron-nickel, nickel, titanium, copper, aluminum alloys | Ø1000 x 1500 (1280) | Parts can be cooled in water, oil, alkali solution, or in molten nitrate, alkali (isometric hardening) |
| Low-oxidation heat treatment of all grades of steels, cast irons and iron-nickel, nickel alloys in molten salts (tools, small parts prone to decarburization, etc.) | 450 x 450 x 280 (1320) | |
| Low-oxidation heat treatment in a protective atmosphere of argon, nitrogen | 550 x 800 x 400 (1280) | |
| Quenching of billets and parts made of beryllium bronzes in dissociated ammonia in a plant with a water seal | Ø140 x 250 (790) | |
| Heat treatment with high frequency currents | - | It may be necessary to manufacture an inductor for a specific part |
| Cold treatment down to -80 ° С for structural, stainless, tool steels, etc. | 400 x 400 x 400 | |
| Aging, annealing in low vacuum (up to 10 2 mmHg) of copper and copper alloys | 300 x 600 x 200 (500) | |
| Thermal stabilization of the dimensions of complex, dimensional parts made of steels and alloys in aerodynamic heating furnaces | 1250 x 1450 x 2000 (330) | High stability and uniformity of heating |
| Liquid carburizing (in the environment of kerosene thermal decomposition products) | Ø460 x 600 (950) | |
| Design and manufacture of thermal equipment of any complexity | ||
