Cooling plate useful for blast furnaces consists of copper or copper alloy with several coolant holes parallel to the hot side with ratio of hole diameter to mean interhole distance defined by an inequality

摘要

Blast furnace cooling plate consists of copper or copper alloy with several coolant holes in a series separated by gaps and parallel to heating side (2), The ratio of hole diameter to (d) to the mean distance s between adjacent holes is given by the inequality d = s 3d.
