Abstract
PURPOSE: To blow mixed gas only to the arbitrary range of a hot slab and enable the local scarfing by providing reciprocatable pistons and partition plates within the manifold for supplying the mixer gas to a scarfing nozzle.
CONSTITUTION: A manifold 5 is formed to two or more steps and pistons 6 are disposed reciprocatably in the respective steps. Partition plates 10 are mounted spacially from the pistons 6 in the respective steps of the manifold 5 to form mixing chambers 11. Fuel gas and oxygen are supplied respectively through feed pipes 11a, 11b into the mixing chambers 11 and are mixed in the mixing chambers 11. The mixed gas is supplied only to the unit of the scarfing nozzle 3 of the corresponding portion, whereby the back face 1b of a hot slab 1 is locally scarfed. The portions of partial scarfing are arbitrarily selected by moving the pistons 6 and partition plates 10 by the moving mechanisms of the rack gears 7 provided to the piston rods 6a.
