Mouldable fire- or heat-resistant refractory material is shaped into a heat-resistant layer and burnt, so as to form the wall of a mould used to cast a cooling block with coolant linkage running in a barrel-stave pattern. One or more pipes, through which coolant flows, are then mounted inside the mould, and a cooling block is cast by pouring in molten metal into the space formed in the mould. |
