ABSTRACT:
A method for treating a steel slab containing 2.5 to 4% Si to a temperature not lower than 1260.degree. C. in a continuous heating furnace of the walking-beam type, comprising; charging the slabs into the continuous heating furnace through its charge inlet, transferring the slabs by means of walking-beams in the furnace with the rear end of a preceding slab substantially contacting a front end of a subsequent slab under the condition that the contact time of the slab with fixed beams is not more than three times longer than the contact time of the slab with the transfer beams, and separating the adjacent slabs with a space sufficient to permit remelting of solidified slag adhered between the adjacent slabs approaching the extraction outlet of the furnace.
