FIELD: electrical engineering; production of electric brush materials. SUBSTANCE: proposed method includes rolling, grinding, spreading and hot pressing. Rolling of mixture of coke, graphite and binder is carried out at one step during 10-20 s at temperature range of 110-140 C, i.e. within temperature range when material is in yielding state. EFFECT: reduced specific resistance at provision of high mechanical strength and hardness of contact slippers. 1 cl, 1 tbl |
