摘　　要：研究了升温速率和载荷对耐火材料示差法热膨胀试验结果的影响,并与顶杆法做了对比。结果表明:不同的升温速率和载荷对不同材质的试样影响不同;在0.01 MPa载荷下,示差法的热膨胀试验结果与顶杆法的具有一定的可比性。The effects of the heating rate and the load on the thermal expansion of refractories tested by the differential method were studied and the results were compared with those by the push rod method.The results show that the heating rate and the load have different effects on different materials,and the results by the differential method under 0.01 MPa are comparable with those by the push rod method.

关 键 词：示差法 热膨胀 升温速率 载荷 顶杆法
