Carbonitriding as a Means of Alleviating the Wear of Metallurgical Equipment Parts

详细

This article examines a technology used for surface-hardening – carbonitriding. Carbonitriding reduces the amount of labor involved in making equipment parts while also making them resistant to corrosion. This technology alleviates the wear of carbon-steel disks on a friction machine by a factor of 20–40 and results in a proportionate decrease in the wear of non-hardened shoes mated with the disks. The use of carbonitriding results in a manyfold reduction in the consumption of spare parts for metallurgical equipment. Among the important consequences of the decrease in the wear of parts are a reduction in repair costs, a decrease in the frequency of equipment repairs, and the generation of additional profit due to the accompanying increase in the equipment’s accrued operating time.
