    • Method of forming a furnace cooling element involving casting a metal block or plate (10) around one or more elongated metal tubes (11) which have a protective coating applied thereto, and thereafter the, or each, metal tube (11) is explosively expanded by an explosive charge (12) closer to the surrounding material of the metal plate (10). Also disclosed is a method in which the protective coating on the metal tube is replaced by a full length external shroud tube (21) to increase the thermal efficiency of the cooling element, the inner metal cooling tube (20) is explosively expanded by an explosive charge (23) closer to the surrounding shroud tube (21) prior to casting a metal plate or block (28) around the tube combination (20, 21) to minimise the gap (22) between the outside wall of the metal cooling tube (20) and the inside wall of the metal protective shroud tube (21). Following casting the metal plate or block (28), the metal cooling tube (20) is again explosively expanded closer to the protective shroud tube (21) by a further explosive charge (23').
    • 形成炉冷却元件的方法,包括将金属块或板(10)围绕一个或多个细长的金属管(11)围绕,所述金属管(11)上涂有保护涂层,然后金属管(11)或每个金属管(11)爆炸膨胀 通过靠近金属板(10)的周围材料的炸药(12)。 还公开了一种方法,其中金属管上的保护涂层被全长的外部护罩管(21)代替,以增加冷却元件的热效率,内部金属冷却管(20)由爆炸物爆炸膨胀 在将金属板或块(28)围绕管组合(20,21)铸造之前,更靠近周围的护罩管(21)的电荷(23),以最小化金属冷却管的外壁之间的间隙(22) 20)和金属保护罩管(21)的内壁。 在铸造金属板或块(28)之后,金属冷却管(20)通过另外的炸药(23')再次爆炸性地膨胀到更靠近保护罩管(21)的位置。
