PROBLEM TO BE SOLVED: To make cooling suitable, to prevent the deterioration of erosion, etc., and to obtain the stabilization for long time by constituting a stave cooler with a main body composed of an iron or an iron alloy including a cooling flow-passage and an outer peripheral part composed of a copper or a copper alloy disposed at the outer priphery of the main body. SOLUTION: The stave cooler is composed of the cast iron-made of main body 1 having the cooling flow passage 3 and the copper-made outer peripheral part 2 arranged so as to cover the whole body of the outer periphery thereof. According to this constitution, the outer peripheral portion is held to the low temp. by covering the outer peripheral portion of the main body easily becoming the high temp. with the copper-made member having high thermal conductivity, and while holding the cooling to the suitable degree, the erosion can be prevented. Then, the temp. in the stave cooler is generally at higher temp. in the outer peripheral part than that in the center part and further, at higher temp. in the corner part. Under the temp. condition, etc., in metallurgical furnace, in the case of being the portion whose corosion is considered as the problem only at the corner part, the copper-made member may be disposed only at the corner part, and in this method, it can be avoided to excessively strengthen the cooling.
