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.

Sliding shoe for a pusher furnace

A continuous flow heating oven of the industrial type used for the heating of ingots, sheet material and the like, which may be of light metal or light metal alloy, includes a burner fired with a liquid or gaseous fuel disposed within a heating chamber. The material to be heated is placed within the oven with the convection air currents generated from the burners directed thereon, with the hot combustion gases produced by the flames. In addition, the exhaust gases are compressed and directed back onto the object to be heated interspersing with the convection air currents originally generated to increase the efficiency of heating the material.
