This V Refractory Anchor is a standard simple anchoring system. It is used for light to very dense refractories. For thermal shock application, it is highly advised to use stainless steel fibers as the refractory material. This anchor is designed to use traditional methods of welding. It is used for normal dense refractories. V Refractory Anchor stainless steel fibers are mainly advised for thermal shock application into the refractory material.
