Thermal production

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: hardening for high hardness of finished parts made of steels of type 30x13 (radiation hardening); gas hardening of dies, dies and other tools; annealing of large-sized products for extraction; annealing of complex welded structures made of titanium alloys; thermo-sizing and much more.	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

Quality Control

• Vickers, Rockwell, Brinell hardness testers - for hardness control;
• tensile testing machines and impact devices - to control mechanical properties. It is also possible to determine the mechanical properties at low and high temperatures;
• analysis in a metallographic laboratory - to control grain size, burnout.
