Abstract
A ladle brick leveling set for high temperature molten metal ladles in which specially shaped refractory bricks are disposed in a slightly sloping geometrical configuration so as to compensate for a sloping bottom of a high temperature molten metal ladle. The bricks are disposed in two partial rings each of which is essentially a mirror image of the other so that the height of the leveling set varies substantially uniformly from a high point where the two mirror image portions join to a low point 180 degrees of arc displaced therefrom where the two portions again join. Each of the refractory bricks has a slight taper in height so that the ends of each brick are the same height as the juxtaposed ends of the adjoining bricks.
