Refractory Selection Guide Coreless Induction Furnace - Steel Alloys Click on furnace diagram for product recommendations

We develop, manufacture, and market a variety of products for steel alloys.  We make DRI-VIBE® refractories for all steel chemistries and temperature ranges.  DRI-VIBES provide maximum campaign length for carbon steels, tool steels, manganese steels, alloyed steels, and all other compositions.  We focus on minimizing wear caused by chemical attack, slag attack, thermal cycling, and unexpected temperature excursions.  We also manufacture and sell wet ram refractories for steel melting.  We use alumina, magnesia, spinel, chrome ore, zircon, and other refractory minerals to develop the best possible refractory matrices.
