The present work aimed at a mechanism study of blocking of ladle well by filler sand. Laboratory experiments were carried out using two different chromite based filler sands technically proven. The interaction between the liquid steel and the sand was also studied by using steels containing different contents of Mn and Al. The reaction between the silica phase and the chromite phase was found to be the main mechanism for the sintering of sand. The reaction resulted in a liquid oxide phase, which became the binding phase between the solid oxide grains. The size of silica phase was found to have great impact on the formation of the liquid oxide phase. Faster formation of the liquid oxide phase would lead to more serious sintering of the sand. It was found that the presence of liquid steel enhanced considerably the sintering of the sand and even increased the amount of liquid phase. Higher temperature and longer holding time would make the sintering of the sand more seriously.
