Glass
Glass is the industry with the least tolerance for refractory wear, because the refractory does not just fail — it ends up in the product.
Material systems we route here: Bricks · Ceramic Fibre · Hysil
Where the lining is
Melter superstructure and crown, regenerator chequers and walls, ports and throat, forehearth and distributor, plus the insulation package behind all of it. Annealing lehrs and the surrounding equipment take a much lower duty and are usually a fibre and calcium silicate job rather than a brick one.
What takes it out
Corrosion by molten glass and by alkali vapour, at temperatures near the top of what any material will take. What makes glass different from every other industry on this list is the consequence of that wear: material lost from the crown or superstructure is carried into the melt as stones and cord, so a lining that is wearing at an acceptable rate may still be failing commercially. Judge it on defect counts, not on millimetres. Regenerator chequers see sulphate and alkali condensation on the cooler passes — the same condensation mechanism that troubles cement preheaters, arriving from a different direction. Downstream, forehearths and distributors fail more often from thermal cycling and from patch repairs made in a hurry than from corrosion.
How we specify against it
Purity and low open porosity through anything that faces glass or its vapour, and a clear line between what contacts the melt and what does not — the two are separate specifications and pricing them as one is how the superstructure ends up under-specified. Behind the hot face, insulation that holds shell temperature down without driving the hot face hotter; raising insulation performance always moves heat into the lining in front of it, so the package is designed as a whole. Campaign planning matters more here than anywhere else on this list, because a glass furnace is not opened casually: the specification is written for the full campaign, and the insulation and backup are part of it rather than an afterthought priced at the end.
What we stock for it
High alumina brick and shapes for superstructure and port work, ceramic fibre blanket, module and paper for backup, veneering and expansion joints, and calcium silicate board and block where a rigid, load-bearing insulating layer is wanted rather than a fibre. Annealing lehrs and the surrounding equipment take a much lower duty and are usually a fibre and calcium silicate job rather than a brick one.
