Shaped vs monolithics
What it is
Shaped refractories are pre-formed bricks and blocks laid like masonry; monolithics are castables, gunning mixes and ramming masses installed as a seamless lining in situ
Monolithics install faster, need less skilled bricklaying and have no joints to fail, and their share has been rising globally
Impact on industries
- Monolithics shorten furnace downtime during relining, which is worth far more to a steelmaker than the refractory cost itself
- Application know-how and installation service become part of the product, so the supplier captures value beyond material
- Performance depends on correct on-site mixing and placement, so failures are often application errors that still damage the supplier's reputation
- Shaped products retain the most demanding positions, so the mix shifts gradually rather than one displacing the other
