Trough castables and rocking runners are employed on the casthouse floor to transfer molten iron tapped from blast furnace to torpedo cars or iron ladles. HI-TECH proposes appropriate refractory materials and high performance solutions for whole cast house which includes main trough, slag runner, iron runner, tilting runner and others, to ensure total reliability, achieve long campaigns and to reduce maintenance downtime.
Trough castable has much less porosity than trough ramming mass because of its monolithic dense structure. As a result of its reduced porosity, trough castable offers better resilience to iron & slag penetration in the lining and thus ensures safer operation. HI-TECH trough castable containing high purity grains offers superior abrasion resistance and crack resistance and can be safely used in the main trough of the casthouse.
Our HI-RAM range of ramming mass series for casthouse runners has consistently improved performance benchmarks of both trough life and performance reliability. HI-TECH special HI-RAM mass can be used for both initial lining and for periodic repairs in the metal and by-pass runner zones. Its chemical composition and physical properties combine to guarantee low consumption values with longer service life and fewer repairs.
