镁质捣打料

Magnesia Ramming Material

　　* DD-1 & DD-2

　　该产品采用优质镁砂和优质合成镁钙砂为原料，控制适宜的粒度级配使其具有更好的堆积密度。易烧结，抗溶蚀、抗冲刷。可用作电炉炉底打结料，干法施工。

　　The product uses high-quality magnesia and high-quality synthetic magnesia calcium sand as the main raw materials,and controls the appropriate particle size distribution to make it have a better packing density.Easy to sinter,corrosion and erosion resistant.It is used as knot material at the bottom of electric furnace and dry construction.

　　* DD-3 & DD-4

　　该产品采用优质镁砂为主要原料，加入化学结合剂，硬化过程中产生陶瓷结合。抗溶蚀，抗冲刷性能好。适用于冶金炉炉底及填充边角缝处，施工时需加水5%－7%。

　　The product uses high-quality magnesia as the main raw material, adding chemical bond, forming ceramic bond in the hardening process. Good corrosion and erosion resistance. It is suitable for the bottom of metallurgical furnace and filling the corner joints, 5% - 7% water should be added during construction.

　　* DD-6

　　该产品采用优质烧结镁砂、电熔镁砂为主要原料，高温性能好，抗侵蚀、耐冲刷。适用于冶金炉炉底及出钢口、AOD和VOD炉的易损处。使用本产品时应注意人体防护。

　　The product adopts high quality sintered magnesia and electric fused magnesia as the main raw material, with good high temperature performance, erosion resistance and erosion resistance. It is applicable to the furnace bottom and tap hole of metallurgical furnace, vulnerable parts of AOD and VOD furnace. Pay attention to human protection when using this product.

　　* DD-10 & DD-18

　　该产品采用镁砂铬矿、合成镁铬砂为主要原料，加入复合添加剂，选择适宜的粒度组成。因为有高温相镁铬尖晶石，材料对低碱度渣的抗侵蚀性能优异。主要用于RH炉、VOD炉和有色冶金炉等。

　　The product uses magnesia chromite, synthetic magnesia chromite as the main raw material, adding composite additives, and selecting appropriate particle size composition. Because of the high temperature phase magnesia chrome spinel, the material has excellent corrosion resistance to low alkalinity slag. It is mainly used in RH furnace, VOD furnace and non-ferrous metallurgical furnace.
