Synopsis : A shaft type smelting furnace (SF) for high carbon manganese ferro-alloys was blown in on June 24, 1985 and Mizushima Ferro-alloy Co., Ltd. The SF has an inner volume of 398 m3 and a production capacity of 270 t/d (H/C FeMn) and is equipped with a center feed Cardan type bell-less top (CTBL) and radiation type recuperator for pre-heating blast air. The features of the SF operation are the high coke rate, high dust rate and high top gas temperature compared with those of the blast furnace. The SF has cooling plates arranged from bosh to upper shaft with a small pitch, wearing plates cooled, and cooling-type CTBL rotating frame. Gas cleaning system is reinforced with a cyclone in addition to the conventional system. The outline of the construction of the SF is described in this report. |
