The plate is made in the form of metal
pipes filled with a coolant and sealed at the ends thereof. A cooler for a shaft furnace comprises a metal plate for protecting the
furnace walls from the heat effect arranged in the way of heat flow and a
means for cooling said plate. The
coolant-filled ends of the pipes are rigidly fixed to the plate, and the
coolant-free ends of said pipes are mounted within a cooling chamber
with the coolant circulating therethrough. The
plate is formed of two layers, namely, a high-heat-conducting layer and a
low-heat-conducting one, the former facing the furnace working space
and the latter being presented to the furnace wall. The cooling chamber is
arranged exteriorly of the furnace wall. The coolant-free ends of the
pipes are disposed slightly above those filled with the coolant.
