OMZ-Spesial Steels part of OMZ Group has completed construction of the new heat-treatment furnace.

The new shaft electric furnace of the vertical type is used for heating by normalizing, hardening and drawing of workpieces of turbo-generator rotors of steam turbines, propeller shafts and high-chromium long-grade workpieces. Volume of investment in the project constitutes RUB 106 million.

The furnace will produce heat-treated products with a diameter of up to 3.5 meters and a length of 12 meters. It meets all modern standards and requirements relating to new generation vertical thermal furnaces. The accuracy of temperature control is ± 5°C, heating rate is up to 80°C/hour. Cooling rate is up to 80°C/hour.

The new furnace will perform thermal treatment of blanks from now cultivated and promising new high-chromium steels. Quenching temperature can reach 1150?C. Currently, none of the existing manufacturing facilities at Izhorskiy Industrial Complex have a vertical furnace which produces thermal operations at this temperature. In addition the launch of the new vertical furnace will provide a 10% reduction in power consumption for conducting heat treatment.
