Forsterite-elastified magnesia brick

Refratechnik Cement offers FORMAG® 88 forsterite-elastified magnesia brick designed for use in cement rotary kilns. This magnesia forsterite brick grade serves as a safe all rounder in sintering zones of cement rotary kilns. Its density and apparent porosity come up to those of conventional magnesia spinel bricks. Due to a cold crushing strength of 50 Mpa, its increased elasticity leads to an excellent thermal shock resistance of 100 cycles. High melting temperatures of its main components (magnesia 2,800°C, forsterite 1,890°C) result in good refractory values of >1,700°C. Due to the specific thermal conductivity of forsterite, FORMAG® 88's thermal conductivity is lower than those of conventional magnesia spinel bricks. The medium iron oxide content of 2 per cent provides a good coatability. FORMAG® 88 is thermochemically insensible and highly resistant to alkali salt condensates. Due to this, FORMAG® 88 is suitable for chrome ore-free applications in burning zones.
