Flooding による溶鉱炉の棚吊 : 溶鉱炉の棚に関する研究 II

概要

Furnace hanging is possibly caused by flooding. It is confirmed as a result of our experiments by a furnace model and a small scale test blast furnace that the flooding condition in packed column is qualitatively applied to the blast furnace by multiplying the correction coefficient. Coefficients are experimentally evaluated to be 0.5 and 0.35 in case of uniform and mixed coke size respectively. Present blast furnaces are operated nearly at the limiting flooding condition. It may safely be said that the furnace approaches the flooding condition, when the increase of blast volume is frequently accompanied with furnace roughness, slip or hanging. Constitutional improvement of blast and more delicate control of burden preparation must be contemplated for increasing the prodution rate.
