METHOD OF MANUFACTURING WIRE FROM HARD DEFORMABLE STEEL Russian patent published in 1995 - IPC

FIELD: manufacture of welded or fused wire. SUBSTANCE: composite ingot is manufactured by means of fusing of expendable electrode in the upper part of crystallizer into the gap between ingot reinforcing member and crystallizer. Reinforcing member is made up as thin-walled tube closed with covers on both sides. Tube is filled with ground alloying components, which have different fusing point. Chemical composition and mass of fusible electrode are similar to these features of the ingot base. Besides alloying components having higher fusing point are positioned in central part of core to improve process characteristics of the arc. EFFECT: improved processing. 2 cl
