<p>TOP BLOCK STOP In an adjustable slab mold having side, end, top and bottom blocks, a top block stop is positioned at one end of the top block opposite the riser opening. The top block stop is engageable with the side blocks and has means for applying a force to the riser end of the top block which is directed along the longitudinal axis of the top block. The magnitude of the engaging force applied is equal to or less than the statis frictional force existing between the sides of the top block and the side blocks of the mold assembly. Thermal forces on the top block stop caused by metal heating the top block are greater than the engaging force.</p> |
