摘要
采用致密刚玉（ＦＤＣ）和电熔白刚玉（ＦＷＣ）为主要原料，研究了活性ΑＡＬ２Ｏ３微粉、电熔镁砂（ＦＭ）细粉对ＲＨ浸渍管浇注料施工性能、力学性能的影响。研究表明：添加适量活性ΑＡＬ２Ｏ３微粉，能提高浇注料高、中、低温的力学强度，且对浇注料的施工性能无明显的不利影响；而加入少量的电熔镁砂细粉，能调节浇注料的线变化率与低温强度。
By adopting fused dense corundum(FDC) and fused white corundum(FWC) as the main raw materials,the influence of active α-Al2 O3 micro powder and fused magnesia(FM) powder on the construction performance,m echanical performance and microstructure of RH-dipping tube castable was invest igated.The results show that adding appropriate quantity of active α-Al2O3 micropowder can improve the castable's mechanical strength while affecting not its construction capability and adding a small amount of fused magnesia powder can adjust the line change rate and low temperature mechanical strength of the castable.
