Tapered cooling plate for shaft furnace - is received in recess in lining wall bounded by shaped refractory members

摘要

A shaft furnace has cooling plates inserted into recesses in the furnace lining. Each recess is bounded by shaped refractory members each having tapering widths which conform with a corresponding taper in the width of the cooling plate.. The recess is dimensionally stable even when the cooling plate is removed. The shaped members provide good thermal contact with the cooling plate. Cu sheets may be provided between the plate and the shaped members to improve the thermal contact. The cooling plates can be exchanged without radical working of the refractory lining of the furnace. There is more efficient cooling of the refractory lining.
