LADLE IMPACT PADS; SHAPED REFRACTORY BRICKS CAPABLE OF BEING LOCKED TOGETHER TO FORM SUCH PADS FOR USE IN POURING HIGH TEMPERATURE LIQUIDS

摘要

A refractory brick that has a rear portion with a geometrical concavity on one side and a corresponding convex projection on the other side, the concavity and projection being matched so that the concavity mates with the corresponding projection of a similar refractory brick when the two are disposed in side-by-side relationship. Extending perpendicular from the base portion is a generally rectangular projection such that when a plurality of bricks are disposed in a side-by-side array, they are locked together by the mating concavities and projections, and the generally rectangular projections extend inwardly to form a thicker lining to withstand the force of a tap stream of molten metal for a longer duration.
