Abstract
The invention discloses a kind of production methods of stainless-steel seamless pipe, stainless-steel seamless pipe is immersed in acid solution and is chemically reacted, then pressure flush of water surfaces externally and internally is used, dotted reconditioning is carried out to surface defect existing for stainless-steel seamless pipe after pickling, stainless-steel seamless pipe is fixed on oiler, it is fixed, using the hairbrush of rotation to surfaces externally and internally oiling, lubrication, the beneficial effects of the present invention are: while the production method and its application of a kind of stainless-steel seamless pipe of the invention, improve production efficiency, also it can guarantee stable product quality, disappeared with special cleaning solution and washes steel pipe steel pipe can be made to obtain uniform surface quality, it improves service life, and the present invention proposes several different Cold-forming process for different demands, it can satisfy different consumer demands, the sale face of expanding, improve economic benefit.
Description
Technical field
The present invention relates to the production method of seamless steel pipe, specially a kind of production method of stainless-steel seamless pipe.
Background technique
Stainless-steel seamless pipe is the seamless steel pipe using material for stainless steel material, has extraordinary anti-oxidant spy
Property, safety and sanitation are widely applied the fields such as food, medicine, heating, domestic water, air-conditioning return water, build and promote according to hardware steel
The data at center shows that stainless-steel seamless pipe is imitated than passing the heat transfer effect of blunderbuss carbon steel seamless steel pipe with more good heat transfer
Fruit, and service life use is longer.Stainless-steel seamless pipe achieves more general application in current many fields, which adopts
With food-grade stainless steel material, there is antirust very outstanding, the characteristic of good antiscale property, therefore the quality of stainless steel just represents not
The quality of rust steel seamless steel tube, therefore the production technology of stainless steel is particularly important, the stainless steel art method of the prior art
It is unable to satisfy the demand of application, the stainless steel service life of production is short, and frequently replaces steel pipe then and will increase production cost, therefore have
Necessity is made process without paulin steel pipe with stainless steel to seamless steel pipe and further improves.
Summary of the invention
The purpose of the present invention is to provide production methods of a kind of stainless-steel seamless pipe and preparation method thereof, on solving
State the problem of proposing in background technique.
The purpose of the present invention is be achieved by following technical proposals: a kind of production method of stainless-steel seamless pipe,
It comprises the technical steps that:
1) pickling: stainless-steel seamless pipe being immersed in acid solution and is chemically reacted, and then uses pressure flush of water surfaces externally and internally；
2) dotted reconditioning thinning surface: is carried out to surface defect existing for stainless-steel seamless pipe after pickling；
3) oiling: stainless-steel seamless pipe is fixed on oiler, fixed, is applied using the hairbrush of rotation to surfaces externally and internally
Oil, lubrication；
4) it is cold worked: stainless-steel seamless pipe being carried out as needed to carry out cold rolling or cold-drawn or reaming, three kinds of Cold-forming process
Selection one is cold worked；
5) spy cuts cleaning solution cleaning: when stainless-steel seamless pipe is placed on brewed one section in the container full of special cleaning solution
Between, then filter in clear water and then rinsed again with clear water；
6) it is heat-treated: stainless-steel seamless pipe is subjected to molten heat treatment；
7) it examines: stainless steel seamless pipe is finally examined, the property of product after the parameter for the above each process of upchecking is implemented
Energy index, and fed back；
8) it checks: using the straightness and curvature of multiple roll straightener correction stainless-steel seamless pipe.
The pH value of the acid solution requires to be 3-6.
The cold working requires accomplished below in zero degrees celsius.
The beneficial effects of the present invention are: a kind of stainless steel of the invention mentions while the production method and its application of seamless steel pipe
High efficiency also can guarantee stable product quality, is disappeared with special cleaning solution and washes steel pipe steel pipe can be made to obtain uniform surface
Quality improves service life, and the present invention proposes several different Cold-forming process for different demands, can satisfy
Different consumer demands, expands sale face, improves economic benefit.
