镁砂简介
镁砂是耐火材料最重要的原料之一，分为烧结镁砂，轻烧镁砂，电熔镁砂三大类。用于制造各种镁砖、镁铝砖、捣打料、补炉料等。含有杂质较多的，用于铺筑炼钢炉底等。含有杂质较多的，用于铺筑炼钢炉底等。高纯镁砂是选用天然特级菱镁矿石经轻烧、细磨、制球、超高温油竖窑煅烧而成，是制砖、不定形耐火材料优质原料。电熔镁砂由高纯菱镁石轻烧粉经电熔制得，熔制过程中一部分SiO2还原成SiO2逸出，另一部分SiO2由于与MgO比重相差悬殊而向外层迁移，使镁砂纯比，镁砂晶粒粗大。中档镁砂是以MgO含量为95％的轻烧氧化镁为原料，经压球、高温竖窑煅烧等工艺生产而成。产品烧结程度好，结晶致密，是生产中档镁质耐火制品的优质原料。中档镁砂产品的耐火温度可以达到1800-2000℃左右，他是属于一种碱性耐火原料，他的产品是精心选用特级和一级菱镁矿石经过提纯、轻烧、细磨、压球、高温竖窑二次烧结而成,产品可以广泛用于镁砖及耐火材料行业使用。常用粒度规格： 0-1, 1-3，3-6, 6-8mm。
Magnesia refractory material is one of the most important raw materials, divided into sintered magnesia, light burned magnesia, fused magnesia three categories. Used in the manufacture of various kinds of magnesite brick, magnesium aluminum brick, ramming material, repairing, etc. Contain a more impurities, are used to construct steel furnace bottom, etc. Contain a more impurities, are used to construct steel furnace bottom, etc. High purity magnesite is made of natural superfine magnesite writing light burned, fine grinding, ball, ultra high temperature oil shaft kiln calcine, was brick, monolithic refractories quality raw materials. By high purity fused magnesia magnesite stone light burning powder made by fused, in the process of the melted part of SiO2 escape back into SiO2, another part of SiO2 with MgO style proportion to outer difference migration, make pure than magnesia, magnesia coarse grains. Middle-grade magnesia is 95% of the content of MgO style light burned magnesia as raw material, after the ball, such as high temperature shaft kiln calcining process. Product good sintering degree, crystal density, is the high quality raw materials for the production of middle-grade magnesia refractory products. Middle-grade magnesia refractory temperature can reach 1800-1800 ℃ or so, he belongs to a kind of alkaline refractory raw material, the product is carefully selected premium and level magnesite stone after purification, light burned, fine grinding, ball pressure, high temperature shaft kiln sintering, products can be widely used in magnesite brick and refractory industry. Commonly used size specifications: 0 and 1, 1-3, 3-6, 6 -- 8 mm.
镁砂制作工艺
先将高纯电解镁砂、镁粉进行三次煅烧。目的是让电解镁砂、镁粉充分膨胀、收缩。在膨胀、在收缩。膨胀收缩率几乎为零。然后安颗粒大小比例进行配比。加入粘结剂、抗裂剂、稳定剂、其它材料。搅拌成干式混合料。
High purity electrolytic first to three calcined magnesia, magnesium powder. The goal is to make electrolytic magnesia, magnesium powder fully expand and contract. The expanding and shrinking. Expansion shrinkage rate is almost zero. Then Ann particle size proportion ratio. Add binder, anti-cracking agent, stabilizer, and other materials. Stir into the dry mixture.
