Description
Technical field
The present invention relates to a kind of manufacturing of seamless tube, be specifically related to the corronel seamless tube that a kind of UNS NO4400 alloy is made.
Background technology
Seamless tube is a kind of rectangular steel that hollow section, periphery do not have seam that have.It is the steel pipe of chemical etching dielectric corrosions such as weak corrosive medium such as anti-air, steam, water and acid, alkali, salt.Claim the Stainless Acid Resistant Steel pipe again, along with the enforcement of China's policies of reform and opening to the outside world, national economy obtains to increase fast, and cities and towns dwelling house, public building and Tourist facilities are built in a large number, and hot water service and domestic water supply have been proposed new requirement.Quality problem particularly, people more and more pay attention to, and require also to improve constantly.
The a lot of corrosive medium corrosion of corronel ability.Its higher Ni content makes it that good stress-corrosion-cracking resistance be arranged under the water-based etching condition.This alloy has good anti-nitric acid, organic acid corrodibility, but the erosion resistance in sulfuric acid and hydrochloric acid is limited.Except the possible origination point corrosion of halogenide.In the mixture of water, steam and steam, air, carbonic acid gas, also has good erosion resistance.Owing to have comprehensive and good comprehensive performances, in all trades and professions, obtained to use widely, this all makes traditional seamless tube can't reach requirement, and the making method of traditional seamless tube is made the corronel seamless tube, not only wastes resource, and complex procedures.
Summary of the invention
The object of the present invention is to provide that a kind of seamless tube surface corrosion resistance nature improves, superior product performance standards, reduced cost of manufacture and the simple corronel seamless tube of operation.
Technical scheme of the present invention is, a kind of corronel seamless tube, described corronel seamless tube comprises by weight percentage: copper is 28-34%, iron is 1.6%-2.5%, and manganese is 1.4%-2%, and carbon is 0.05%-0.15%, silicon is 0.3%-0.8%, sulphur is 0.14%-0.24%, and the nickel of surplus, and the manufacturing step of described corronel seamless tube comprises:
(1) preparation of blank and to the check of blank performance,
(2) batching is heated the eleven punch 11 of going forward side by side and handles,
(3) blank is carried out reconditioning and handles,
(4) blank is carried out the thermal enlargement typing and handles,
(5) blank is heat-treated,
(6) to blank align, interior mill, outward the mill and carrying out flaw detection,
(7) finished product is tested, and sprays word, packs, weighs and outbound.
In a preferred embodiment of the present invention, described thermal treatment comprises heating, insulation, annealing and cooling.
In a preferred embodiment of the present invention, described processing temperature is 960 ℃-1100 ℃.
In a preferred embodiment of the present invention, described heat-treatment of annealing temperature is 680 ℃-730 ℃.
In a preferred embodiment of the present invention, described cooling temperature scope is 460 ℃-610 ℃.
Of the present invention is a kind of corronel seamless tube, has high strength, high anti-corrosion, anti abrasive good physical property, has the advantage of long service life simultaneously in various acid, alkaline media.
Description of drawings
Fig. 1 be a preferred embodiment of the present invention process flow diagram.
Embodiment
Below preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.
Of the present invention is a kind of corronel seamless tube, referring to shown in Figure 1, described corronel seamless tube step of manufacturing comprises the preparation of (1) blank and to the check of blank performance, (2) batching being heated the eleven punch 11 of going forward side by side handles, (3) blank being carried out reconditioning handles, (4) blank being carried out the thermal enlargement typing handles, (5) blank is heat-treated, (6) to blank align, interior mill, outward the mill and carrying out flaw detection, (7) finished product is tested, and sprays word, packs, weighs and outbound.
Further specify, described thermal treatment comprises heating, insulation, annealing and cooling, and described processing temperature is 960 ℃-1100 ℃, and described heat-treatment of annealing temperature is 680 ℃-730 ℃, and described cooling temperature scope is 460 ℃-610 ℃.
Further specify, in heat treatment process, can not contact sulphur, phosphorus, lead and other low melting point metal, otherwise can damage the performance of material, should note removing such as dirts such as lubricating oil, fuel.Period is at 30min, hydrofluoric acid plays the effect of deoiling enough fast and effectively and tube surface is not had the influence of turning white of any peracid; the material of thin-walled tube also can adopt quick air cooling, and the above purpose reaches desirable surperficial corrosion resistance nature and improves, improve the superior performance standard 1.1-1.2 times.
A kind of corronel seamless tube of the present invention has improved corronel seamless tube surface corrosion resistance nature, and the superior standard of performance of seamless tube reduced the cost of manufacture of seamless tube, and production process is simple.
The above only is the specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; any those of ordinary skill in the art are in the disclosed technical scope of the present invention; variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
