Beschreibung
Zusammenfassung:	The invention relates to walking sill furnaces, in particular bilateral and/or mixed heating ones incorporating sills cooled with water or some other fluid, for heating iron metallurgy products, such as slabs, billets and blooms. The invention attenuates the depth of local cooling (black stripes) across the contact areas of the products to be heated with the stationary and walking cooled sills. According to the invention, the top surfaces of the sills whereon the products to be heated are made to rest either directly or indirectly by means of riders, follow -- as viewed in plan view -- a non-parallel pattern to the longitudinal axis of the furnace over at least part of the furnace length, and in particular an inclined pattern which may converge to and/or diverge from the furnace longitudinal axis, being preferably in the form of a number of inclined and staggered successive sections.
