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.
