| Abstract: | The 180 mm ×1200 mm slab of atmospheric corrosion-resisting steel 09CuPTiRE(≤0. 12C,0.06~ 0. 12P,≤0.020S,0.25～0.50Cu,≤0.03Ti,0.01～0.04RE)is produced by 80 t converter-ladle argon stirring-vertical-bending slab caster process. With using improved process measures such as controlling Cu/Ti≤20,P content ≤ 0. 11%,RE content 0.01%~0.03%, using special mold powder for steel 09CuPTiRE,mold liquid level fluctuation ≤10 mm and decreasing secondary cooling water rate,the occured rate of longitudinal crack of steel 09CuPTiRE decreased from original 15% to 0.5%. |
