摘 要:Monolithic refractory castables comprising a hydraulic bond are still used in a vast majority of cases because of their flexibility and robustness,despite many developments for chemical as well as non-cement castable *** drying can however be a challenge,in particular for deflocculated dense castables of the low cement castable *** publications have been released on this topic for the last ten years,but they often focused on the drying mechanisms or on the addition of drying *** paper presents some experimental results on the effect of the composition on the drying properties,especially on the effect of silicon carbide,used for its high thermal conductivity,and on the matrix *** also introduces two laboratory tests to study and iteratively improve the drying schedule of a given castable *** results show that the spalling resistance and the vapor pressure build-up are significantly influenced by the *** is also shown that the castable properties after drying can be altered if the heating rate is very high.
