有关部门调查钢厂用的轻烧镁球主要含量有60%、65%、70%，这个含量区间的价格钢厂愿意接受，这几个含量的轻烧镁球溅渣护炉效果明显，有的钢厂能达到炉龄20000炉。多个国家和地区等都在使用。一些国内大钢厂，用轻烧镁球后生产成本比以往大大降低，经济效益增加。
      镁球规格有多种（10mm-40mm）,也有60mm,根据各钢厂需求，它的主要含量是氧化镁（MgO）,并有活性，提高炉龄。经过机器压制的镁球强度更高，能充分发挥自己在钢水中的作用，同时取代白云石。轻烧镁球更能减少渣量，同时提高镁含量。高熔点的氧化镁（2800度）在炼钢中起到保护作用。

    70%含量轻烧镁球指标：:氧化镁含量70-73%、二氧化硅4.1-4.8%、氧化钙2.1-2.52%、三氧化二铁1%左右、三氧化二铝1.25%、水分1-4%（根据季节变化）、烧失量17%左右，  

The relevant departments surveyed that the main content of light-burned magnesium balls used by steel mills were 60%, 65%, and 70%. The steel mills were willing to accept the price in this content range. The steel plant can reach a furnace age of 20,000 furnaces. Used in many countries and regions. In some large domestic steel mills, the production cost after using lightly burned magnesium balls is greatly reduced than before, and economic benefits are increased.

       There are various specifications of magnesium balls (10mm-40mm) and 60mm. According to the requirements of various steel mills, its main content is magnesium oxide (MgO), which is active and increases the furnace age. Magnesium balls pressed by the machine have higher strength, can fully play their role in molten steel, and replace dolomite. Light-burned magnesium balls can reduce the amount of slag and increase the magnesium content. High melting point magnesium oxide (2800 degrees) plays a protective role in steelmaking.

     70% content light-burned magnesium ball index: 70-73% magnesium oxide, 4.1-4.8% silicon dioxide, 2.1-2.52% calcium oxide, about 1% ferric oxide, 1.25% aluminum oxide, and water content 1 -4% (depending on the season), loss on ignition is about 17%,

    轻烧镁球(70%以下含量)出口不用配额，海关编码：2519909990，离J9九游会官网近的港口有大连港（大窑湾）、营口鲅鱼圈港。钢厂用轻烧镁球有散装、吨包。镁球价格在200元/吨-420元/吨（氧化镁含量 二氧化硅含量 包装 散装 等因素）。求真务实 双赢发展。

Light-burned magnesium balls (content below 70%) are exported without quotas, customs code: 2519909990. The ports near us are Dalian Port (Dayao Bay) and Yingkou Bayuquan Port. Light-burned magnesium balls for steel plants are available in bulk and in tons. The price of magnesium balls is between 200 yuan / ton and 420 yuan / ton (magnesium oxide content, silica content, packaging, bulk, etc.). Seeking truth and being pragmatic and win-win development.
