Abstract

A method and an apparatus for operating a pusher type furnace for reheating metal slabs for rolling sheet or strip therefrom, including an advance control of fuel quantity supplied to different zones of the furnace and an advance control of the pushing speed through the furnace on the basis of information about the slabs, the final product to be obtained and the rolling practice, such information being processed during the rolling.
