Self-flow castables

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.

Self-flow castables belong to the group of deflocculated castables and can be found in Medium Cement Castable, Low Cement Castable, Ultra-Low Cement Castable.

Self-flow castables can be designed with the universal SECAR® 71, SECAR® 712 and SECAR Plenium®, SECAR Xeniom™ and CMA 72.

The selection of refractory cement is done according to the targeted service temperature. Please click on: http://www.secar.net/Solutions-for-refractories
