Steelmaking operations use a variety of fluxes to treat liquid iron and steel for achieving the product specifications. Traditionally, calcium fluoride has been used in such fluxes. However, due to its detrimental environmental effect, substitute materials are being more commonly used. An effective flux in treating steel is calcium aluminate. This flux is usually produced from earth minerals and is imported to North America from Asia. SCEPTER Inc. is working with METKEM Innovation Inc. to develop a similar or superior flux, using not earth minerals, but rather waste and by-products from the aluminum industry. To evaluate the melting properties of this flux, and investigate the effect of some additions for improving its performance, the present collaborative research has been proposed. The long term outcomes of the research, if successfully implemented will be (a) reducing the environmental impact of steel treatment by eliminating calcium fluoride, (b) reducing the environmental footprint of aluminum production, by using its waste materials, and (c) establishing production facilities in Canada, that could result in job and wealth creation.

炼钢作业使用各种熔剂来处理铁水和钢水，以达到产品规格。传统上，氟化钙已被用于此类助熔剂中。然而，由于其对环境的不利影响，替代材料越来越普遍使用。处理钢的有效熔剂是铝酸钙。这种焊剂通常由地球矿物生产，从亚洲进口到北美。 SCEPTER Inc. 正在与 METKEM Innovation Inc. 合作开发类似或优质的助焊剂，不使用地球矿物，而是使用铝工业的废物和副产品。为了评估这种焊剂的熔化性能，并研究一些添加剂对其性能的改善效果，目前提出了合作研究。如果成功实施，该研究的长期成果将是（a）通过消除氟化钙来减少钢铁处理对环境的影响，（b）通过利用废料减少铝生产的环境足迹，以及（c）在加拿大建立生产设施，这可能会创造就业机会和财富。
