Abstract
The invention relates to a production process of a large-caliber thin-walled seamless stainless steel pipe, which comprises the following production steps: (a) firstly, preparing 0Cr18Ni10Ti stainless steel pipe bloom made by an arc furnace and electroslag remelting or vacuum induction and electroslag remelting; (b) after pickling and solution treatment, carrying out first cold-rolled processing for the stainless steel pipe bloom to make a coarse steel pipe; (c) after degreasing and solution treatment, carrying out the crude steel pipe by cold-drawing and caliber-enlarging processing for the coarse steel pipe to make a large-caliber steel pipe; (d) after degreasing and solution treatment, carrying out second cold-rolled processing for the stainless steel pipe to make a refined steel pipe; and (e) after degreasing and solution treatment, straightening, pipe cutting, pickling and inspection, the refined steel pipe being made into a large-caliber thin-walled seamless stainless steel pipe finished product. With the process of the invention, the length of the steel pipe can reach or exceed 6000mm, and the steel pipe does not produce twisting and spinning amboss phenomenon and the like.
Description
Technical field
The present invention relates to the production technology of a kind of large-caliber thin-walled seamless stainless steel pipe in the metallurgy industry.
Background technology
In metallurgy industry, last one technology of large-diameter thin-wall seamless steel pipe generally is to adopt spinning process production, but adopts spinning process, and on the one hand, the length of spinning steel pipe generally about 2000mm, can't meet or exceed 6000mm; In addition, the large-diameter thin-wall seamless steel pipe of employing spinning process production twists, is easy to generate the spinning line easily, precision is relatively poor.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiencies in the prior art, a kind of production technology of large-caliber thin-walled seamless stainless steel pipe is provided, can production length reach steel pipe and the smooth irrotationality embossing of steel tube surface of 6000mm.
The technical solution adopted for the present invention to solve the technical problems is: a kind of production technology of large-caliber thin-walled seamless stainless steel pipe has following production stage: (a) prepare earlier to add electroslag remelting melting or vacuum induction adds the 0Cr18Ni10Ti stainless steel pipe that electroslag remelting melting is made by electric arc furnaces; (b) the stainless steel pipe carries out the cold rolling crude steel pipe of being processed in first road after pickling, solution treatment; (c) crude steel pipe is carried out the cold-drawn hole enlargement and is processed into large-diameter steel pipe after degreasing, solution treatment; (d) large-diameter steel pipe carries out after degreasing, solution treatment that second road is cold rolling is processed into refining steel pipe; (e) refining steel pipe is made the large-caliber thin-walled seamless stainless steel pipe finished product through degreasing, solution treatment, aligning, Pipe Cutting, pickling, check.
The invention has the beneficial effects as follows: the cold rolling processing of last one process using of the present invention substitutes the spinning process that uses in the prior art, for the specification nominal outside diameter is the steel pipe of 55.00～120.00mm, nominal wall thickness 0.25～1.00mm, adopt technology of the present invention to make, steel pipe length can meet or exceed 6000mm, and steel pipe has further improved the quality of production and the production precision of seamless steel pipe less than the generation of phenomenons such as distortion, spinning line.
The specific embodiment
Embodiment one: a kind of production technology of large-caliber thin-walled seamless stainless steel pipe has following production stage: (a) prepare earlier to add electroslag remelting melting or vacuum induction adds the 0Cr18Ni10Ti stainless steel pipe that electroslag remelting melting is made by electric arc furnaces; (b) the stainless steel pipe carries out the cold rolling crude steel pipe of being processed in first road after pickling, solution treatment; (c) crude steel pipe is carried out the cold-drawn hole enlargement and is processed into large-diameter steel pipe after degreasing, solution treatment; (d) large-diameter steel pipe carries out after degreasing, solution treatment that second road is cold rolling is processed into refining steel pipe; (e) refining steel pipe is made the large-caliber thin-walled seamless stainless steel pipe finished product through degreasing, solution treatment, aligning, Pipe Cutting, pickling, check.
The specification nominal outside diameter that technology of the present invention is made is the stainless steel heavy caliber seamless steel pipe of 55.00～120.00mm, nominal wall thickness 0.25～1.00mm, its length: 〉=6000mm, wall thickness tolerance :+0～0.10mm, plug tolerance: ± 0.05mm, tube bending degree :≤2mm/m, grain size: 〉=5 grades.And phenomenons generations such as not distortion of steel pipe, spinning line, eliminated defectives such as steel pipe distortion, spinning line effectively, further improved the quality of production and the production precision of seamless steel pipe.
