摘要

PROCESS FOR THE PRODUCTION OF STAINLESS STEEL PIPES SUBMITTING A STAINLESS STEEL OF RAW MATERIAL THAT CONTAINS, IN MASS, 10 TO 30% CR, FOR DRILLING LAMINATION TO OBTAIN A HOLY SHIELDING, SUBMITTING THE SHIELDING LAMINATION TO OBTAIN A CRUDE LAMINATION TUBE FOR FINISHING USING A CHUCK BAR, WITH A GRAPHITE-FREE LUBRICANT, AND HEATING THE CRUDE TUBE IN A REHEATING OVEN AND SUBMITTING THE LAMINATION FOR FINISHING LAMINATION FOR DIMENSIONING This is a process for the production of stainless steel tube that comprises the cutting lamination of a raw material stainless steel containing, by mass, 10 to 30% Cr, to obtain a hollow shield, the lamination to elongate the hollow shield using a mandrel bar, together with a graphite-free lubricant, to obtain a crude lamination pipe for finishing and heating the crude pipe in a reheating oven and submitting it to finish laminating through dimensioning lamination to produce a hot finished tube and then subjecting that tube, like a mother tube, to cold work to produce a stainless steel tube. In the reheating furnace, the crude finishing lamination tube is heated to 1000 198 C or more and subjected to heating in which an oxidizing gas is blown into the tube, through which a stainless steel tube, the which is prevented from forming a carbonized layer on the inner surface of the tube, can be produced. When the finishing lamination through the dimension lamination to obtain a cold working mother tube is performed through the 860 to 1050 198 C stretch reducing lamination, an annealing thermo-treatment of the cold working mother tube can be omitted. Therefore, a stainless steel tube with excellent surface quality can be produced effectively.
