为了解决炼钢甩碱性耐火材料供不应求和提高镁质材料的质量问题,湘潭钢铁厂和我院负责进行的“从白云石尾矿中提取优质人造镁砂”的局部工艺试验装置(日产1吨)从8月1日起正式运转。目前已生产出一批湿Mg(OH)2,并用这种Mg(OH)2先在1000-1100℃下轻烧混炼、成型,再在1650-1680℃烧结,获得了含MgO96.28%,CaO2.35%,Fe2O30.36% In order to solve the problem of oversupply of alkaline refractories and improving the quality of magnesia materials, the local process test device (1 ton per day) for the extraction of high quality artificial magnesia from dolomite tailing is carried out by Xiangtan Iron and Steel Plant and our institute. From August 1 from the official operation. At present, a batch of wet Mg (OH) 2 has been produced and lightly burned and kneaded at 1000-1100 ° C using this Mg (OH) 2, and then sintered at 1650-1680 ° C to obtain a mixture of MgO containing 96.28% , CaO25.35%, Fe2O30.36%
