INCREASING RESOURCE OF SCRAPER CONVEYORS
Bulletin of Kharkov National Automobile and Highway University, 2020 Abstract. We have studied the properties of steels BRK, 18ChGT, 20ChGNB used for the manufacture of sidewalls of chute conveyor pans after various treatment regimes in order to select the most appropriate one. The working conditions stipulate high demands to chute conveyor pan material with respect to strength and durability, and the term of chute ...
