摘要

Steel contains 0.2% to 0.4% by weight, no more than 1.2% Cr, 0.15% to 0.45% C, no more than 0.01%, no more than 0.02% P, no more than 80 ppm n, no more than 25 ppm oxygen, and other confidence and impurities are inevitable. The manufacturing process of non sewing steel pipe includes: (a) manufacturing a master heating furnace in a high-power electric furnace, followed by a secondary metallurgical process, processing al, refining, desulfurization, floating bag, The ferroalloy and copper alloy are orange to achieve the specified steel preparation; (b) continuous flushing; (c) hot rolling on continuous laminate; and(d) Standard pyrolysis of the steel; or (E) placing the standardized steel in austenizazion, then heating and resale, with a minimum resale temperature of 490 ℃; or (f) placing the rolled steel directly under contraction, temperate zone and resale.
