Abstract

PURPOSE:To obtain a linear additive for steel with superior productivity and stability in quality by extrusion molding additive raw material based on Ca and Al of above a predetermined grain size, and tightly covering the resulting wire with a steel tape while attaching the tape lengthwise. CONSTITUTION:Additive raw material 4 based on +100 mesh grain size Ca or Ca and Al is charged into heated container 1 and extrusion molded into wire 5 through die 3. Wire 5 is continuously passed through forming unit 7 while attaching mild steel tape 6 lengthwise to tightly cover wire 5 with tape 6 at an overlapped state, thus obtaining composite linear additive 8 for steel. By this method troubles due to breakdown of the wire during extrusion is minimized and continuous operation is maintained, resulting in enhanced productivity. By limiting mixture of deteriorated matter, the quality of the additive is stabilized.
