EXTRUSION SIMULATION 1 OF 6

In relation to shaped refractories, TEIDE REFRACTORY SOLUTIONS has production lines for manufacturing shaped, pressed parts and shaped, extruded parts.

• In shaped, pressed parts, the final geometry is achieved by placing the material in a mould, in which pressure is then transmitted by a press. The shaped parts (150-650 kg/cm2) are denser, less porous and have greater mechanical resistance.

In extruded, shaped parts, the final geometry is achieved with an extrusion machine to which an ex trusion nozzle is coupled. Extruded parts are obtained at lower pressures (15-50 kg/cm2) and are therefore more porous and have less mechanical resistance than pressed parts. However, extruded parts may be less dense, as they permit the creation of extrusion holes that facilitate heat exchange and reduce latent heat in the furnace. In technological terms, this is a more delicate process as it give rise to the need to treat the green refractory paste like a highly viscous fluid. A poor extrusion process design reduces the useful life of extruded, shaped refractories.
