Molten refractory material for iron and steel smelting and preparation method and application thereof
The invention belongs to the technical field of preparation of refractory materials, and provides a molten refractory material for steel smelting and a preparation method thereof. The invention provides a molten refractory material for iron and steel smelting. The molten refractory material comprises the following raw materials in parts by weight: 60-90 parts of magnesium oxide, 3-30 parts of aluminum oxide, 1-30 parts of zirconium oxide, 0.2-2 parts of calcium oxide and 0.2-2 parts of silicon oxide. The molten refractory material provided by the invention can meet increasingly harsh steel development requirements; the service life of a refractory product prepared from the molten refractory material is more than ten times of that of an existing magnesia carbon brick product, and due to thefact that the service life is prolonged, the molten refractory material consumed for producing each ton of steel is reduced by 80%-90% compared with a traditional material, and the refractory material is saved; and the purity of the steel can reach more than 90%.
本发明属于耐火材料的制备技术领域，提供了一种钢铁冶炼用熔融耐火材料及其制备方法。本发明提供的钢铁冶炼用熔融耐火材料，包括如下重量份数的原料：氧化镁60～90份、氧化铝3～30份、氧化锆1～30份、氧化钙0.2～2份、氧化硅0.2～2份。本发明提供的熔融耐火材料能够满足越来越苛刻的钢铁发展要求，本发明的熔融耐火材料制备的耐火产品是目前镁碳砖产品使用寿命的十倍以上，由于提高了使用寿命，使生产每吨钢材所消耗的熔融耐火材料比传统材料降低了80～90％，从而节省了耐火材料；而且钢材的纯度可以达到90％以上。
