Abstract: To optimize processes for stable commercial production of C194 alloy sheet and strip, several key steps were investigated. Various procedure and the parameters for melt purifying, finishing rolling temperature, split aging parameters, and water cooling capacity during casting and hot rolling were analyzed. The results imply that shield gas atmosphere along with alloying element of Mg and Ce help greatly on purifying the melt. C194 alloy sheet and strip with finishing rolling temperature higher than 750 ℃ and split aging treatment at 550 ℃, 2 h+450 ℃, 2 h can obtain excellent integrity properties. The cooling capacity during casting and on-line quenching after hot rolling are also key factors influencing the quality of C194 alloy sheet and strip.
