FIELD: manufacturing of electric conductors. SUBSTANCE: drums are heated by means of heat production in contact junction between carbon material and drum surface when current runs through it. In addition convergence of temperature in different drums is controlled by means of use both carbon electrodes and metal electrodes and by means of cooling drums by water flows. EFFECT: decreased burning time, decreased electric power consumption, simplified design. 2 cl, 1 dwg |
