In the conveyor, an exhaust gas flow passage for allowing the exhaust gas inside the flue to pass through the scrap from its surface layer to its lower layer is formed inside the layer of the scrap, so that pre-heating of the scrap can be efficiently effected throughout the whole layer of the scrap.</p> |
