Description
技术领域
本发明涉及透气砖芯浇注料技术领域，尤其涉及一种生产透气砖芯浇注料偏稀调节工艺。
背景技术
炼钢精炼时用的吹氩砖芯属于功能性材料，精炼时通过其往钢包里吹高压惰性气体氯气，其压力在1-15Mpa,再加之在1550-1700℃高温，且砖体从上至下有较大的温度梯度，条件十分苛刻，从而要求砖芯材质要有较高的均一性，砖体在此条件下保持良好的体积稳定性，如果在生产过程中出现不同程度的材质成分偏析，就会出现砖体断裂、炸裂等现象，从而严重影响透气砖芯的使用寿命，进而影响整个钢包的使用寿命以及钢包的正常周转。
透气砖芯的生产制作基本采用以浇注料形式浇注成型。影响砖芯质量的决定因素：一是科学合理的技术配方：二是生产制作的工艺过程控制，而在制作过程中又尤为重要的是浇注料要具有优良的流动性和稳定性，使用青岛镁铝公司提供的ADS0.4％和ADW,0.3％配合使用使得浇注料的制作上有极佳的减水效果，加水量保持在5％以内，同时浇注料的流动性也非常优良，也基本上可以满足透气砖的生产工艺需要，但存在浇注料在注入模具定型的振动过程中，容易出现颗料偏析和料种偏析的问题，颗粒料在振动过程中容易出现一定程度的下沉，同时浆料往上部集中，不同料种因密度不同也会有不同程度的偏析，这样在坯体定型后又没办法改变，从而导致坯体的材质和成分比例由上而下均有一定的差别，这样的坯体在后续的烧制过程中和形成产品后的使用过程中，由于砖体上下材质成份不均，在高温和温度梯度较大条件下，其物理化学变化也不完全一致，砖体内部就会产生一定的结构应力、从而大大增加砖芯在使用过程中出现断裂和炸裂的概率，进而影响透气砖芯大的使用稳定性以及使用寿命。
因此，怎样解决现有透气砖芯浇注料在注入模具定型的振动过程中，容易出现颗粒料偏析和料种偏析的问题，颗粒料在振动过程中容易出现一定程度的下沉，同时浆料往上部集中，不同料种因密度不同也会有不同程度的偏析的问题，成为长期以来难以解决的技术难题。
鉴于上述原因，现研发一种生产透气砖芯浇注料偏稀调节工艺。
发明内容
本发明是为了克服现有技术的不足，提供一种生产透气砖芯浇注料偏稀调节工艺，能够通过在透气砖原料中加入ADS1和ADW1，增加混料后浇注料的流动性，能够通过在透气砖原料中加入羧甲苯纤维素，提高透气砖原料中颗粒料的粘度，避免混料后的浇注料在注入模具定型的振动过程中颗粒料下沉，有效的解决了现有透气砖芯浇注料在注入模具定型的振动过程中，容易出现颗粒料偏析和料种偏析的问题，颗粒料在振动过程中容易出现一定程度的下沉，同时浆料往上部集中，不同料种因密度不同也会有不同程度的偏析的问题。
为了实现上述目的，本发明采用如下技术方案，一种生产透气砖芯浇注料偏稀调节工艺，将透气砖芯原料、外加剂加水后，在强制式搅拌机中搅拌3-5分钟后制成浇注料；
所述的外加剂的组分及占透气砖芯原料总质量的百分量为：ADS10.4wt％，ADW10.3wt％，羧甲苯纤维素0.1wt％；
所述的加水的水量占透气砖芯原料总质量的百分量为4-5wt％。
所述的透气砖芯原料的组分为：微孔刚玉颗粒45-65wt％，微孔镁铝尖晶石颗粒5-15wt％，电熔致密刚玉颗粒5-10wt％，α-Al2O3微粉5-13wt％，氧化镁微粉2-6wt％，铬渣细粉2-6wt％，氢氧化铝微粉1-5wt％，碳化物微粉1-5wt％，以上各组分的含量之和为100％。
本发明的有益效果是：本发明能够通过在透气砖原料中加入ADS1和ADW1，增加混料后浇注料的流动性，能够通过在透气砖原料中加入羧甲苯纤维素，提高透气砖原料中颗粒料的粘度，避免混料后的浇注料在注入模具定型的振动过程中颗粒料下沉，有效的解决了现有透气砖芯浇注料在注入模具定型的振动过程中，容易出现颗粒料偏析和料种偏析的问题，颗粒料在振动过程中容易出现一定程度的下沉，同时浆料往上部集中，不同料种因密度不同也会有不同程度的偏析的问题，使得通过改进后的浇注料生产出的透气砖芯在使用过程中的稳定性和使用寿命大幅度提升。
