We found the reasons that a lot burned-magnesia brick is scrapped because of split by delve into the production technology.
通过对烧成镁砖生产工艺的深入研究,找到了烧成镁砖批量开裂报废的原因,并通过一系列的试验工作,找到了解决方案,即通过加入"复合结合剂"来有效地杜绝制品烧后开裂现象,而且"复合结合剂"的加入没有降低制品的理化性能。
The unfired magnesia-calcium brick has been developed and used in 90t LF refining furnace in centain steelplant.
以合成镁钙砂、电熔镁砂为原料,以无水树脂做结合剂,添加适量的添加剂,研制出了LF精炼炉用不烧镁钙砖。
The production and application status of magnesite-dolomite refractories such as fired magnesia-calcium brick,unburned magnesia-calcium(carbon) brick and Mg-Ca coating mixture for tundish etc are introduced and it is pointed out that magnesite-dolomite refractories should be developed on high CaO content,high grade,seriation and non-shaped refractories in the near future.
介绍了我国烧成镁钙砖、不烧镁钙(碳)砖和镁钙质中间包涂料等镁钙质耐火材料的生产和使用现状,指出今后我国的镁钙质耐火材料应向高CaO含量、高档次、系列化和不定形方向发展。
