APPARATUS FOR GUIDING WIRE-SHAPED ADDITIVE TO MOLTEN METAL

摘要

PURPOSE:To prevent buckling deformation of a wire-shaped additive in the stage of supplying said additive at a high speed by providing plural sets of guiding means which are formed with spaces for passage of the wire-shaped additives between the engaging surfaces of paired upper and lower guiding rollers in a route for supplying the additive from driving rollers up to a ladle at a prescribed interval. CONSTITUTION:A guiding device G supplies a wire-shaped additive 2 delivered from driving rollers 1, 1' to the molten steel 4 in a ladle 3. Plural sets of the 1st guiding means G1 formed with a space 6 for passage of the additive 2 between the engaging surfaces of paired upper and lower guiding rollers 5 and 5' and the 2nd guiding means G2 consisting of tubular members 7 moving together with said means are disposed in a route for supplying the additive 2. Then the stable supply of the wire-shaped additive is made possible under the conditions for supplying said additive at a high speed of >=200m/min.
