摘要： A system for supporting and cooling a furnace roof comprised of refractory bricks comprises a plurality of roof support members extending across the furnace and being supported from above the furnace roof. The support members are provided with internal channels for circulation of a cooling fluid, and are provided with side surfaces adapted to support rows or refractory bricks between adjacent roof support members. The system eliminates the need to suspend individual bricks from above the roof, and provides simultaneous support and cooling of the roof structure.

摘要： Some metallurgical furnaces have a tapblock that is blocked during operation of the furnace. The tapblock may be opened by lancing, drilling, tapping or by other methods to release metal from the furnace. By monitoring acoustic emissions during the opening process, feedback may be provided to improve the opening process and to avoid excessive damage to the tapblock, the cooling elements, a refractory lining of the tapblock or other elements of the metallurgical furnace.
