氧气底吹转炉的主要特点是在炉底多氧枪供氧,同时可以随氧流喷入石灰粉.因此它具有以下特点:吹炼平稳、金属收得率高;脱磷、脱硫好,熔池搅拌好,易于冶炼低碳钢.从氧气底吹转炉第一座设备投产到现在已有3500万吨的生产能力,而且在Q-BOP/OBM的技术上取得新的进展.例如日本川崎千叶厂,O-BOP的煤气回收率达125.5标米~3/吨,炉体寿命达到3150炉,炉底寿命1646炉,Q-BOP转炉终点命中率达到96.1%.这些将给氧气底吹转炉的发展指出光明的前景.
Oxygen bottom blowing converter is characterized by oxygen in the bottom of the oxygen gun at the same time with the oxygen flow into the lime powder. So it has the following characteristics: smooth blowing, high metal yield; dephosphorization, desulfurization, melting Pool mixing well, easy to smelt mild steel.Of the first equipment from oxygen bottom blowing converter has been put into operation now has 35 million tons of production capacity, but also Q-BOP / OBM technology made new progress.For example, Kawasaki, Japan Leaf plant, O-BOP gas recovery rate of 125.5 standard meters ~ 3 / ton, furnace life of 3150 furnaces, furnace bottom life of 1646 furnaces, Q-BOP converter end point hit rate of 96.1%. These will be oxygen bottom converter The development pointed out a bright future.
