Abstract
PURPOSE: To prevent surface oxidation and save fuel by soaking a slab in an imperfect combustion zone and heating the same in a perfecr combustion zone wherein air is added to this at the time of heating the slab continuously up to rolling temp. then soaking the same to a uniform temp.
CONSTITUTION: A slab 8 passes continuously through a heating zone 3 where it is heated up to rolling temp., and a soaking zone 4 where it is heated in a manner as to decrease the skid marks of the slab 8 and to make its temp. uniform. On the other hand, a burner 12 for heating the zone 4 is regulated to make imperfect combustion, whereby the slab 8 is soaked while the oxidation of the surface of the slab 8 is being prevented. Next, this imperfectly burnt gas is conducted to the zone 3, where it is added with the air from an injection pipe 16 to make perfect combustion, thereby heating the slab 8.
