用に耐えることができる。Therefore, the portion of the inner wall 17 formed by the electroformed magcro brick 18 is exposed to the most severe conditions thermally, chemically and physically, and not only the finned water-cooled copper pipe 21 but also the water-cooled copper pipe 21 is cooled. Forced cooling using box 10. As shown in FIG. 2, the water-cooling box 10 introduces water from an external device (not shown) from a water outlet 12 of a socket 13 to cool it, and at the same time exerts the cooling effect on an electroformed magro brick 18 to cool an inner wall 17. Since the copper concentrate is smelted inside the shaft portion 16, it has a large amount of sulfur, and the water-cooled box 10 is exposed to a very harsh condition and corrodes, melts and wears. As a result, the service life is approximately 2 to 5 times that of a conventional copper water-cooled box without overlay, and it can withstand long-term use of approximately 2 to 7.5 years.
