Self-flow castables define a specific refractory concrete family that is used when vibration casting is not adapted. This is typically the case for complicated or intricated shapes too narrow to be vibrated.
Self-flow castables possess the characteristics to be very fluid and to fill molds / structure by their own weight without any external energy, such as vibration.
Self-flow castables usually contain high quality aggregates such as bauxite, tabular alumina, andalusite or fillers such as fume silica, reactive alumina or high fluidifying agents such as Peramin® AL 200 and Peramin® AL 300.
The selection of refractory cement is done according to the targeted service temperature. Please click on: http://www.secar.net/Solutions-for-refractories
