We design, manufacture and supply the complete refractory assembly for our System 5oo forehearths. However, in addition to fulfilling the needs of our own systems, we can also supply the complete refractory substructure and superstructure for most other designs of forehearth, and can also offer the services of our team of designers and engineers to upgrade and improve existing forehearth systems.
PSR-SM62 62% Al2O3
PSR-SM62 is the primary material used for forehearth & distributor superstructures and is an in-house development that combines high strength and low creep with excellent resistance to thermal shock. Single-piece roof blocks in SM-62 can be manufactured for forehearths up to 72” (1830mm) wide.
PSR-333 11.25% ZrO2
Due to it’s excellent thermal shock characteristics, PSR-333 is used for superstructure applications where the refractory may be exposed to excessive changes in temperature, such as mantle blocks, skimmer blocks and any roof blocks which are installed hot. It is also an excellent material for colourant forehearth superstructures where its unique closed pore surface inhibits penetration from the corrosive vapours associated with the frit feeding operation.
