Slagging method with lime replaced with calcite in converter

The invention discloses a slagging method with lime replaced with calcite in a converter. The slagging method comprises the following steps that (1) the suitable calcite is selected for replacing part of the lime, and the calcite and lime not be replaced form a slagging material; (2) the dosage of the slagging material is calculated; (3) the thermal balance in the converter is calculated, and the charging amounts of melted iron and scrap steel are adjusted; (4) the slagging material are added in batches, and the oxygen supply amount in the converter is adjusted; and (e) smelting end point temperature testing, sampling and tapping preparing are conducted. Efficient utilizing of the mineral resources is achieved, meanwhile, production cost is reduced, energy saving and emission reducing are realized, and environmental pollution is reduced. 本发明公开种转炉中用方解石替代石灰的造渣方法，包括以下步骤：a)选取合适的方解石用于替代部分石灰，所述方解石与未被替代的石灰形成造渣料；b)计算所述造渣料的用量；c)计算转炉内热平衡，调整铁水及废钢装入量；d)分批次加入所述造渣料并调整转炉内供氧量；e)冶炼终点测温、取样、准备出钢。该方法实现矿产资源的高效利用同时降低生产成本，节能减排，减少环境
