  • Refractory Lining - Rongsheng Kiln Refracotry

    2018-3-13 · Single layer wear-resistant lining consists of dense refractory, generally 3/4' to 1' thick, anchored with hex mesh grating or independent anchoring systems designed for wear-resistance. When independent anchoring systems such as S-Anchors, Hex Cell, etc., are used, refractory should contain stainless steel fibers. These linings should be considered as having limited insulating value and designer is cautioned to consider heat transfer (heat flux) in design of equipment. Application of single layer wear-resistant linings …
