| In order to achieve higher temperatures and to obtain the aims of increased iron amount and saved cokes in ironmaking process, the problem on technique of hot-blast furnace is still topics that blast furnace workers concerning.This thesis investigates the problems from practice of production of the hot-blast furnace No.l in Jisco,a primitive conclusion of performance efficiency of this hot--blast furnace has been drawn and the technical path to achive higher temperatures of hot-blast at the Jisco has been paved on the basis of in-depth research and careful measurement technical data on the spot.At the same time a predictive analysis of the hot-blast stove with ball-type used medium 380m3 blast furnace in construction by a subcompang of Hong Yang. Shan Xi has been given. |
