Gunning material for improving RH semi-dry method gunning sintering performance and preparation method of gunning material
The invention relates to a gunning mix for improving RH semi-dry method gunning sintering performance and a preparation method of the gunning mix. The gunning mix is prepared from the following raw materials in parts by weight: 45-90 parts of magnesite clinker granules, 15-30 parts of 180-mesh magnesite clinker powder, 2-6 parts of sodium hexametaphosphate or sodium tripolyphosphate, 2-6 parts of sodium bentonite, 2-6 parts of slaked lime, 2-6 parts of solid sodium silicate, 0.05-0.1 part of fiber and 20-25 parts of a composite sintering improver, wherein the composite sintering improver is a mixture of iron tailing powder, jade powder and aluminum ash. The sintering performance of an existing semi-dry method gunning material is optimally designed and improved, so that the semi-dry method gunning material is suitable for the gunning maintenance operation of the RH dip pipe, the adhesiveness is enhanced, the sintering performance is optimized, the erosion resistance is improved, the use effect of the RH gunning material is improved, and the purpose of effectively prolonging the service life of the RH dip pipe and the circulating pipe is achieved.
本发明涉及一种改善RH半干法喷补烧结性能的喷补料及其制备方法，所述喷补料是由下列重量份数的原料制备而成：烧结镁砂颗粒料45～90份、烧结镁砂粉180目15～30份、六偏磷酸钠或三聚磷酸钠2～6份、钠基膨润土2～6份、熟石灰2～6份、固体硅酸钠2～6份、纤维0.05～0.1份、复合烧结改善剂20～25份，所述复合烧结改善剂为铁尾矿粉、玉石粉和铝灰的混合物。通过对现有半干法喷补料的烧结性能进行优化设计和改进，使之适合RH浸渍管的喷补维护作业、增强附着性、优化烧结性、提高抗侵蚀性，达到改善RH喷补料使用效果，从而实现有效延长RH浸渍管和环流管使用寿命的目的。
