The technological process of steel smelting at “ArcelorMittal Temirtau” JSC includes three stages: converter smelting of semi-finished products, ladle treatment, and continuous casting of slabs. According to the current technology, a desired flowability of the refining slag is created in the ladle-furnace unit by thinner additives, such as fluorspar. When using fluorspar, toxic fluorine emissions aggravate the environmental situation at the worksite. In addition, the presence of fluoride compounds in the slag adversely affects the durability of the ladle lining. Without modifying the technological process and the consumption of slag-forming agents (lime), solid slag mixtures, based on aluminum oxide, can be used in the ladle-furnace unit to eliminate fluorine emissions into the workshop atmosphere, neutralize the negative effect on the resistance of the ladle lining slag belt, as well as reduce the cost of steel due to the refusal of fluorspar and reduced consumption of aluminum for slag deoxidization.

“安赛乐米塔尔特米尔套”股份公司的炼钢工艺流程包括三个阶段：半成品转炉熔炼、钢包处理和板坯连铸。根据现有技术，精炼炉渣所需的流动性是通过诸如萤石等较稀的添加剂在钢包炉单元中产生的。使用萤石时，有毒氟的排放会加剧工地的环境状况。此外，炉渣中氟化物的存在也会对钢包内衬的耐用性产生不利影响。在不改变工艺流程和成渣剂（石灰）用量的情况下，可在钢包炉装置中使用以氧化铝为基础的固体炉渣混合物，以消除氟排放到车间大气中，中和对生产的负面影响。提高了钢包衬渣带的阻力，并且拒绝萤石，降低了钢的成本，减少了渣脱氧铝的消耗。
