Abstract
When an Al-killed steel consisting of, specially, 0.005% .ltoreq. [N] .ltoreq. 0.007%; 10 .times. [N] .ltoreq. Sol.Al. .ltoreq. 0.12%; and the ratio Sol.Al.%/[N]% controlled within the range of 10 to 20, is continuously cast, hot rolled, coiled at a high temperature, cold reduced and finally continuously annealed under special requirements, the steel strip is not at all inferior to the commercial base strip in mechanical properties and is made under high productivity and exhibits excellent uniformity in qualities.
