| Popis: | Results are given for a complete processing scheme for manufacturing small diameter grinding balls of hardness groups III and IV produced from small cross-section continuously-cast carbon steel billet. The steel chemical composition and rolling and heat treatment regimes proposed have made it possible to produce balls of grinding hardness groups III and IV since the beginning of mastering ball rolling mill 30–80. Industrial tests of grinding balls 40 mm in diameter of hardness group IV performed under Southern Mining and Processing Plant conditions demonstrate that grinding efficiency of finished class size –0.074 mm is better by 3.1% higher and specific consumption of grinding balls is 8.83% lower than in the case of using grinding balls of hardness group III produced by DMKD or Azovstal Metallurgical Combine. |
