Profiled refractory brick, for vaults (roofs), cast in material to be melted and vaults (roofs) comprising such bricks

摘要

The present invention relates to a profiled refractory brick, for vaults (roofs), cast from materials to be melted, based on metallic oxides, produced in the form of a prism having a trapezoidal base surface, characterised in that, in the widest of its parallel lateral faces, at least one open channel 1, orthogonal to the longitudinal axis of the profiled brick, is provided. Application to the construction of furnace vaults (roofs). IMAGE
