Refractory Repair

STELBOLT was designed to both repair and compliment existing furnace linings. It can easily penetrate and hold onto a refractory fiber, insulating firebrick or lightweight monolithic lining. For repairs, a blanket patch can be placed over a damaged area and very simply the STELBOLT is drilled or ratchet-driven through the new hot face and into the backup lining. STELBOLT will easily penetrate wallpaper, modules and low-density board linings. To improve lining efficiencies that have degraded after months or years of service the STELBOLT simplifies the “veneering” process. Apply one or two layers of new blanket and drill the STELBOLT through to a tightened position.
