Purpose of the development: To strengthen the overall tubular steel products.

Recommended application field: In the metalworking, oil and gas and defense industries.

Technical characteristic: Cryoagent - liquid nitrogen. Range of temperature control - (-173- 150) ° С. The rate of temperature reduction - from 20 ° C to -173 ° C: 1-5 ° C min. Holding with temperature -173 ° C: 24-48 h. Holding with temperature 150 ° C: 5-6 h. The volume of nitrogen tank - from 23 liters.

Advantages over analogues: The technology of cyclic heat treatment of products from special steels: tools, cutters, mills and other products increases the microhardness, wear resistance and overall strength of the processed products. This is due to changes in the microstructure of materials and removal of internal stresses of materials.

The development stage readiness: Ready for application

Description of the development:
()
Developed cryogenic systems of cyclic heat treatment of small-sized tools and overall tubular products based on thermoregulated nitrogen devices with a special container of processed samples, contains heating elements. The cryogenic chamber provides regulation and maintenance of the set temperature with high accuracy in the temperature range -173 ° C to 150 ° C. The technological process is performed with the possibility of programmable digital control of the cooling-heating cycles with the required speed, after which the products are kept at the required temperature level and with a specified time.
