JIS S45C COIL WELDING METHOD FOR CONTINUOUS COLD ROLLING |
摘要 |
PURPOSE: A welding method for continuous rolling of JIS S45C high-carbon steel sheet is provided to cooling-roll a steel sheet of the thickness demanded in the room temperature by using continuous pickling rolling mill facility. CONSTITUTION: A welding method for continuous rolling of JIS S45C high-carbon steel sheet comprises the next step. The cross sections of JIS S45C high-carbon steel sheet and low-carbon steel plate are fixed to a fixing board clamp electrode, having a communication function, and a feeding board clamp electrode, respectively(S-21). Ark is generated by contacting the cross sections of JIS S45C high-carbon steel sheet and low-carbon steel plate(S-22). The carriage clamp electrode is continuously carried in a first feeding speed to be heated to a junction temperature by using consecutive contact, melting and splashing(S-23). The carriage clamp electrode is continuously carried to fixing board clamp electrode in a second feeding speed which is faster than the first feeding speed(S-24).
