Blast Furnace Tap Hole Clay Products

ProductMore InformationDescription
Taphole Clay
RSR 1170 R-AM PDS
SDS
An anhydrous taphole clay that has been used for more than ten years on blast furnaces producing 4000-6000 tons of hot metal per day. It is designed for shorter gap times (25- 30 minutes) and is extremely dependable, user-friendly material.
RSR 1170 RPDS
SDS
Formulated with a judicious blend of aluminosilicates and select carbons to fortify the matrix. This provides a cost-effective material that that reduces emissions and therefore environmental citations for an in-city plant location.
RSR 1960-1961PDS An anhydrous taphole clay ideal for use on large blast furnaces operating with high pressure and producing up to 9000 tons of hot metal per day.
RSR 963-14PDS
SDS
specially formulated for high-production blast furnaces. High-alumina clay fortified in the matrix with fused alumina and silicon carbide combined with a metals package that increases overall strength.
RSR 961PDS An anhydrous taphole clay ideal for use on medium-size, high-pressure blast furances producing up to 8000 tons of hot metal per day.
RSR 1170R-2PDS
SDS
Designed for use on blast furnaces producing 4000-6000 tons of hot metal per day. It was developed with an environmental mindset and can be used when 20 to 25-minute gap times are desired.
RSR 1170R Modified XPDS
SDS
Formulated with a judicious blend of aluminosilicates and select carbons to fortify the matrix. This provides a cost-effective material that that reduces emmissions and therefore environmental citations for an in-city plant location.
RSR 1170R-WPDS
SDS
An anhydrous taphole clay that has been used for more than ten years on blast furnaces producing 4000-6000 tons of hot metal per day. It is designed for shorter gap times (25- 30 minutes) and is extremely dependable, user-friendly material.
RSR 908APDS
SDS
Designed for large, high-pressure, high-production blast furnaces containing additions to enhance slag resistence and provide exceptional casting performance.
RSR 1175PDS
Optimized for two-taphole blast furnaces producing up to 5000 tons of hot metal per day. It contains mullite, silicon carbide, and selected blends of fused aluminas and performs well with older mudguns and drills.
Restoration ClayPDS
SDS
Ideal for use on blast furances and specifically formulated to fill cracks and fissures in the taphole clay column. Fine-grained and fused aluminas along with a special blend of carbides and nitrides make it an effective taphole repair solution.
RSR 963 TPDS
SDS
Designed for use on the largest blast furnaces producing over 10,000 tons of hot metal per day. High-quality materials in high amounts make this an extremely durable clay for optimum taphole performance.
RSR 101PDS
SDS
An anhydrous blast furnace taphole clay designed for use with a conventional drilling practice on medium-size furnaces producing 4000 - 6000 tons of hot metal per day.
RSR AKMPDS Specifically formulated to push (extrude) easily, drill with low resistance, and cast reliably on two-taphole blast furnaces producing up to 8000 tons of hot metal per day.
RSR 457 PDS
RSR 457 is a taphole clay for use on medium sized blast furnaces.
RSR 902 PDS
An anhydrous taphole clay specifically formulated to push (extrude) easily, drill with low resistance, and cast reliably on two-taphole blast furnaces producing up to 8000 tons of hot metal per day.
Alloy Furnaces
RSR Plugging PastePDS
SDS
An anhydrous plugging paste for ferrosilicon alloy furnaces, which is matched to the chemistry of the alloy being produced. It is best suited for manufacturing inoculants.
RSR 1133PDS
SDS
An anhydrous, silica-based taphole clay for blast furances producing less than 3000 tons of hot metal per day. It contains no coal tar products.
RSR 1133 TPDS
SDS
An anhydrous plugging paste for ferrosilicon alloy furnaces, which is matched to the chemistry of the alloy being produced. It is best suited for manufacturing inoculants.
