FORFARANDE FOR ATT KARBOTERMISKT FRAMSTELLA EN FERROBORLEGERING ELLER EN FERROBORSILICIUMLEGERING |
摘要 |
A method of making ferroboron or ferroborosilicon alloys in a low-shaft electrical furnace wherein the burden or charge has at least as a major portion of its carbon carrier, wood chips or particles which are carbonized to wood charcoal during the process and thus the charge has a porosity which permits adsorption action to prevent loss of volatile boron compounds. The charge also contains iron oxide and boron oxide, the electrodes of the furnace effecting a reduction of the boron oxide at a reduction zone just above the floor of the furnace. |
