Refractory Selection Guide Casthouse - Blast Furnace Trough Click on furnace diagram for product recommendations

We design and manufacture a complete group of products for the blast furnace casthouse and iron transfer systems.  V-CAST®, L-CAST®, DRI-VIBE®, TEK PAK, and other product lines have been used for many years in blast furnace casthouse applications from the taphole facing through the iron trough, the slag runner, iron runner, iron tilting runners and the ladles that transfer the iron to the steel shop. V-CAST® FA2L, DRI-VIBE® 660A, TEK-GUN, TEK-PAK 664 Plastic and L-CAST® 564 are all industry standards for casthouse applications.  Allied’s unique design philosophy and state or the art refractory technology for iron troughs can provide refractory performance improvements of up to 50 per cent compared to conventional iron trough designs and materials. The Allied's “Safety Lining System” provides optimum safety and reliability with minimum reduction in working lining thickness, which enables longer campaigns and increased furnace availability.
