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.
Claims7
A sliding shoe arrangement for pusher-type furnaces and serving for the sliding transport of objects to be heated in a predetermined feed direction and which are placed upon said sliding shoe, comprising:
- rail means;
- a sliding shoe cooperating with said rail means and having an at least approximately U-shaped cross-sectional shape and including a web;
- said sliding shoe containing downwardly protruding legs disposed laterally of said web and engaging with said rail means in order to provide a laterally guided supporting of said sliding shoe on said rail means of the pusher furnace;
- at least one sliding element arranged at an inner side of the web of said sliding shoe;
- and
- said sliding element bearing upon said rail means.
