    Our castables are suitable to minimize a regular problem of DRI kilns i.e. accretion christened as RAPIDENSE 60-ACR RAPIDENSE 70-ACR. These have good resistance to accretion with lower wet ability. These properties are further clubbed with excellent abrasion resistance thermal shock resistance (TSR) lead to best performance.
