Sažetak
In this paper, industrial control technical measurements of the heat treatment of high chromium steel rolls (HCS), is presented. Measurements were carried out on the gas fired car bottom chamber furnace Bosio PP-KP 70/1150 in the company Valji d. o. o., Štore, Slovenia. Temperature measurements of the individual heating zones of the furnace, rolls surfaces, the external walls of the furnace and gas consumption were monitored throughout the whole process of heat treatment. The temperature profile of the rolls cross-section was calculated using computer simulation. Periodical measurements of CO and NOx emissions were also carried out with the aim of combustion evaluation and ecological integrity. The successfulness of heat treatment was examined through microstructure observation, hardness measurement and the amount of retained austenite in the heat treated rolls.
