一种COREX熔融还原法非高炉炼铁炉渣的回收处理方法
摘要：
本发明公开了一种COREX熔融还原法非高炉炼铁炉渣的回收处理方法，所述方法是首先将COREX炉渣处理为COREX炉渣微粉，然后应用于配制混凝土的胶凝材料。用本发明公开的350kg/m3胶凝材料的配方配制的混凝土自然养护28天后的强度能达到32～48MPa，混凝土强度等级达到C30～C40。因此，本发明解决了COREX炉渣的回收再利用问题，避免了资源浪费和环境污染，而且回收处理方法简单易行和实用，具有明显的社会、经济和环保效益。
摘要（英）：

The invention discloses a method for recycling slag from non-blast furnace ironmaking by a COREX smelting reduction process, which comprises the following steps that: firstly, COREX slag is processed into COREX slag powder; and the COREX slag powder is used in a gelatinous material for preparing concrete. After the concrete is naturally cured for 28 days, the strength of the concrete prepared by the formula of the 350 kg/m<3> gelatinous material disclosed by the invention reaches 32 to 48MPa, and the strength grade of the concrete reaches C30 to C40. Therefore, the method solves the problem of difficult COREX slag recycling and avoids resources waste and environmental pollution. And the recycling method is simple, easy to implement and practical and creates remarkable social, economic andenvironmental benefits.
