本文阐明了十字石可以作为黑色冶金工业中炼铁的稀释剂,并可加速炼钢工艺的成渣过程。与传统的稀释剂相比,十字石不仅成本低,而且不产生毒性气体。文章还描述了乌克兰地盾区奥西品科夫斯克组内含十字石片岩的地质、产状、矿物组成和化学成分,并对其进行了地质勘探和技术经济分析。 This paper illustrates that Phragmites can be used as a thinner for ironmaking in the black metallurgical industry and can accelerate the process of slag formation in the steelmaking process. Cross-stones are not only less expensive than traditional thinners, but do not produce toxic gases. The paper also describes the geology, occurrence, mineral composition and chemical composition of the Ostikovsky Formation in the Ukraine Shield Area, and provides geological exploration and technical and economic analysis.
