Abstract
The method is offered which allows to increase the wear resistance of bit bodies for continuous miners by means of their additional full hardening. This results in increasing the bit body hardness from 37-42 HRC up to 49-51 HRC, which must bring to increasing in wear resistance approximately of 25 %. The suggestion has been tested with a batch of bits spec. RKS-2 (РКС-2) in the mines of Vorkuta and have demonstrated an increasing in wear resistance compared with that of the bits which had not been exposed to an additional hardening.
