IN230546: A process for the production of high alumina self-flow castables

A process for the production of high alumina self-flow castables by mixing intimately 49.5- 72.5 wt% alumina aggregates of mixed particle grading, 0 - 28 wt % calcined clay aggregates of mixed particle grading, 18-30 wt% fine calcined alumina of blew 325 BS sieve particle size distribution, 2 wt% microfine silica with 11-12 wt% colloidal silica binder to obtain a castable mix, casting the product, air drying at room temperature of 22 - 24 hrs followed by drying at around 110°C for 2 hours, to obtain self flow castables.
