Abstract

The facing is replaceable after use and is composed of a centrifuged hard metal tube i.e. its internal wall is slightly concave over a parabola of revolution and is rough cast, while its outer surface is rectified and concentric with the core; and the connection between the core and facing is made by a low e.g. 250 degrees C m.pt. alloy whose density is approx. that of the facing e.g. has a value of 8. The alloy fills the space between the facing and the core, which is shaped so that shear stresses in the low m.pt. alloy are reduced to a minimum and are replaced by compressive stresses.
