Abstract
A STABLE BLAST-FURNACE OPERATION IS STRONGLY ASSOCIATED WITH THE PERFORMANCE OF TAP HOLE CLAY, AS A POOR MATERIAL COULD LEAD TO AN INEFFICIENT LIQUID DRAINAGE. USUALLY, TAP HOLE CLAY IS DAMAGED DUE TO THE COMBINED EFFECT OF SLAG CORROSION AND PIG IRON EROSION, WHICH HAS RECENTLY BECOME MORE AGGRESSIVE DUE TO THE USE OF CHEAPER RAW-MATERIALS AND LOW-COST OPERATIONAL PRACTICES. ALIGNED WITH SUCH CHALLENGING SCENARIO, SAINT-GOBAIN DEVELOPED A HIGH-PERFORMANCE SOLUTION BASED ON AN INNOVATIVE TAP HOLE CLAY WITH A GRAPHENE-LIKE STRUCTURE, WHICH GUARANTEES AN OUTSTANDING CHEMICAL RESISTANCE AND, AS A CONSEQUENCE, A STABLE AND LONG LASTING PROTECTIVE MUSHROOM
