MANUFACTURING METHOD FOR COLD ROLLED STEEL ROD OR WIRE BY CONTINUOUS CASTING

摘要

A steel furnace melt having a carbon content of 0.2% is such that the deoxidized melt composition consists of oxygen 80-150 ppm with the balance being iron. And the amounts of Mn, Si and Al added satisfy the formula; 0.5≤Mn%/5/Si%+10A %≤1.0 The melt is then continuously cast and the cast product is rolled into bars or wires.
