Calcination mode and transportation mode of active lime
The invention relates to a calcination mode and a transportation mode of active lime for steel-making and a mode of adding the active lime into a steel-making furnace, and belongs to the technical field of metallurgy energy conservation. According to the method, the calcining mode and the operation mode of the active lime of an existing steel-making enterprise and the mode of adding the active lime into a steel-making furnace are changed, an existing continuous lime calcining mode is changed into a small-specification precise calcining mode, and the existing mode that the active lime is cooled and then transported is changed into a heat preservation transportation mode; An existing mode of adding cooled lime into a steel-making furnace is changed into a mode of adding heat-insulating hot high-temperature active lime into a steel-making furnace;the method has the advantages that the activity degree of the produced lime is high, the steel-making energy consumption can be reduced by adding the heat-insulating hot high-temperature active lime into a steel-making furnace for steel-making, the active lime can be quickly melted into slag, the smelting time can be shortened, the fluorite consumption is reduced, the effect of removing P and S elements is improved, the scrap steel ratio of steel-making is increased, benefits are increased, and the cost is reduced.
本发明涉及一种炼钢用活性石灰的煅烧方式和运输模式及加入炼钢炉的方式,属于冶金节能技术领域。本发明改变了现有炼钢企业活性石灰的煅烧方式和运转模式及加入炼钢炉的方式,将现有的连续煅烧石灰方式改为了小规格的精准烧制方式,将现有活性石灰冷却后再运输的模式改为了保温运输,将现有的冷却的石灰加入炼钢炉改为将保温的炽热的高温活性石灰加入炼钢炉,该方法的优点是生产的石灰活性度高,保温的炽热的高温活性石灰加入炼钢炉内炼钢能够降低炼钢能耗,活性石灰能快速熔化成渣,且能缩短冶炼时间,降低萤石用量,提升去除P、S元素的效果,增加炼钢的废钢比,增加效益,降低成本。
