Abstract

A temperature-controlled nitrogen cryostat with embedded high-temperature thermally insulated container holder of treated objects has been created for low-temperature hardening of instruments and machinery. To control the surface temperature of rolls a system for cryoblasting of rolls by nitrogen gas-fluid mixture has been designed.
