Abstract

PURPOSE: To heat the slab of extremely less skid marks with good thermal efficiency by making the hearth metals of the heating furnace by pipes of heat-resisting steel and cooling the same according to need in the case of heating the slabs of copper and special copper alloy to different temperatures.
CONSTITUTION: In a walking beam type heating furnace 1 which heats a slab 3 of Cu or Ni-Cu, its stationary beams 6 and the stanchions 4 thereof, walking beams 9 and their stanchions 8 are made of pipes of 25Cr-20Ni heat-resisting steel. The heating temperatures of the Cu slab are 850W900°C, and the heating temperatures of the Ni-Cu-alloy are 1,000W1,015°C. The service limit temperatures of the Cr-Ni- base heat-resisting steel are 950°C or less. Hence, in the case of heating the Cu slab, both beams and others are not cooled, hence do not cause any heat loss and are not put with skid marks. At the time of heating the Ni-Cu alloy slab, both beams are cooled and are kept at 880W950°C, but there is no need for cooling them down to about 400°C as with beams made of mild steel and therefore there are less heat losses owing to the cooling and the skid marks decrease considerably.
