中档镁砂Medium Magnesite

该砂是所用特极和一层菱镁石，经轻烧、细磨、压球、高温环境竖窑烧结法而成。中低档镁砂硫氰酸盐分子量低、容积体积大、抗渣功能好，使用在打造中低档镁砖或镁质不塑形耐火村料。It is produced by light burning, fine grinding, dry ball in-dentation and sintering in extra high temperature oil shaft kiln with superior and first-class magnesite ore as raw materials.With low imperity content, high volume density and good refus-es resistance, it can be applied to produce medium magnesia bricks and unshaped refractory materials.
