ABSTRACT:
A sliding shoe or member for a pusher or reheating furnace for the sliding transport of substantially bar-shaped heated objects has an essentially U-shaped profile or sectional shape and is provided with downwardly protruding legs for the laterally guided support of the sliding shoe on a rail. At its inner web side the sliding shoe is provided with sliding elements which consist of a material which has a coefficient of friction sufficient for an essentially wear-free feed or advance of the sliding elements and thus the shoes at the central region of the rail at a furnace temperature of about 600.degree. to 700.degree. C. These measures afford sliding characteristics which make it unnecessary to provide additional lubrication between the sliding shoes and the rail.
