Suspended crowns of industrial furnaces, and refractory elements for making such crowns

摘要

A suspended crown of an industrial furnace formed of anchored refractory bricks, additional refractory bricks, and refractory plates. The anchored bricks are formed at one end with means for engaging hooks which secure the bricks to support beams, and at their opposite ends with shoulders for carrying the refractory plates. The sides of the anchored and additional bricks are formed with teeth which mesh with teeth in adjacent bricks. The plates are generally rectangular and provided with parallel channels for reducing their weight.
