Description
技术领域
本发明专利涉及刚玉制作技术领域，尤其是一种镁铝复合刚玉的制作方法。
背景技术
传统刚玉一般只能用于磨料等相关行业，其抗渣性和抗冲刷性并不可靠，尤其在钢铁行业作为耐材使用效果极差。
发明内容
本发明的目的在于针对已有技术存在的缺陷，提供一种镁铝复合刚玉的制作方法，以克服现有技术的不足。
为解决上述问题，拟采用这样一种镁铝复合刚玉的制作方法，该方法采用将普通钢玉与铝镁尖晶石混合，并在高温熔溶状态下制成刚玉与尖晶石狗复合体。
优选的，所述铝镁尖晶石含量不低于10%。
优选的，上述高温温度不低于2000度。
与现有技术相比，本发明具有比传统刚玉耐火材料更强的抗渣性及抗冲刷性。主要用于钢铁行业作为耐材使用.将使钢厂吨钢耐材消耗䧏低30%。刚玉是钢铁行业主要耐材、世界消耗达150万吨国内消耗在50万吨左右。如取代40%普通刚玉;镁刚玉市场前景巨大。
具体实施方式
为使本发明的目的、技术方案和优点更加清楚，下面将对发明作进一步地详细描述。
实施例：
本实施例提供一种镁铝复合刚玉的制作方法，该方法采用将普通钢玉与铝镁尖晶石混合，并在高温熔溶状态下制成刚玉与尖晶石狗复合体。
优选的，所述铝镁尖晶石含量不低于10%。
优选的，上述高温温度不低于2000度。
镁刚玉是由铝镁尖晶石与刚玉在高温熔溶状态下形成的—种复合材料,具有比传统刚玉耐火材料更强的抗渣性及抗冲刷性。主要用于钢铁行业作为耐材使用.将使钢厂吨钢耐材消耗䧏低30%。刚玉是钢铁行业主要耐材、世界消耗达150万吨国内消耗在50万吨左右。如取代40%普通刚玉;镁刚玉市场前景巨大。
镁刚玉需要在更高的温度下才能形成刚玉与尖晶石狗复合体·我公司具有能提供较传统刚玉冶炼炉温更高的流放炉,保証了该产品的顺利合成。
