目前己有3个转炉厂,炉龄超过30000炉。随着炉龄的提高,炉役期内耐火材料的消耗量降低,生产成本或直接经济效益提高;而炉役期间钢产量大幅度增加。但炉龄提高的比例与产量增加的比例之比,3个厂平均为0.9992,说明炉龄大幅度提高后,钢产量没有降低。近10年,钢铁工业迅速发展,采用转炉长寿复吹工艺,碳氧积波动在0.0023～0.0030,渣中TFe降低4%～6%,钢中氧降低(100～250)10-6。

在老练时刻到达后，再通入压缩空气，此刻通入的压缩空气首要是协助固相物进一步冷却，待固相物冷却至9~12℃时即可加水浸取以溶解反响生成的固相物。钛铁矿与硫敌反响生成的钛盐很杂乱，首要有Ti(SO4)TiOSO42H2O、TiOSO4，H2SO4H2O、TiOSO4H2SO42H2O、TiOSO4H2O,TiOSO4等，这些钛的盐安稳性、溶解度都不相同，它们在水和稀中的溶解度依下列次第递减Ti(SO4)TiOSO4H2SO4H2O、TiOSO4H2SO42H2O、TiOSO42H2O、TiOSO4H2O、TiOSO4.因而在酸解操作时要严格操控矿酸比、反响温度等工艺条件，尽量使其生成工艺要求的TiOSO42H2O，避免生成难溶于水的无水氧铁(TiOSO4)。
