Abstract:
A method for making a thin cast strip with reduced meniscus marks includes assembling a pair of casting rolls laterally positioned to form a nip therebetween, preparing molten steel having a carbon content in the range of 0.01 to 0.3% by weight, a manganese content between 0.1 and 0.8% by weight, a silicon content between 0.05 and 0.5% by weight, a calcium content between 0.0008 and 0.004% by weight, an aluminum content between 2 and 500 ppm by weight, having a free oxygen content below about 50 ppm at 1600° C., forming a casting pool of the molten steel supported on casting surfaces of the casting rolls above the nip, and counter-rotating the casting rolls cause thin strip to be casted downwardly from the nip.
