Description
Technical field
What the present invention relates to is stainless steel tube production technical field, is specifically related to a kind of accurate stainless steel bright annealing pipe production technology.
Background technology
Accurate seamless pipe is a kind of being pulled out by essence or a kind of high-accuracy tube material after cold-rolling treatment.Due to accurate seamless pipe inside and outside wall non-oxidation layer, bear that high-pressure non-leakage, high accuracy, best bright finish, clod wash are indeformable, enlarging, flattening free from flaw etc. a little, so be mainly used to produce product that is pneumatic or Hydraulic Elements, as cylinder or oil cylinder, can be seamless pipe, also have welded pipe.Traditional accurate stainless steel seamless pipe production technology more complicated, production efficiency is lower, precision stainless steel pipe is not having to be hard state under annealed state usually, there is no more soft characteristic, therefore need to design a kind of accurate stainless steel bright annealing pipe production technology newly, to meet Production requirement.
Summary of the invention
For the deficiency that prior art exists, the present invention seeks to be to provide a kind of accurate stainless steel bright annealing pipe production technology, technological process is simple, and production efficiency is high, can meet Production requirement, produces high-quality accurate stainless steel seamless pipe.
To achieve these goals, the present invention realizes by the following technical solutions: a kind of accurate stainless steel bright annealing pipe production technology, and it comprises the following steps: 1, Incoming Quality Control; 2, uncoiling: uncoiling process is carried out to supplied materials by uncoiler; 3, strip: the strip after uncoiling process is cleaned; 4, shaping: forming processes operation is carried out to strip; 5, weld; 6, set round, aligning; 7, bright annealing; 8, on-line cooling; 9, drawing tube reducing; 10, eddy current inspection; 11, reel and Length-fixing cutting is carried out respectively; 12, the laggard row air tightness test of reel, finally packs; 13, once flat mouth, chamfering, inspection, packing process is carried out after Length-fixing cutting.
Beneficial effect of the present invention: technological process is simple, and production efficiency is high, can meet Production requirement, can reduce intermediate step, improves lumber recovery, makes accurate stainless steel seamless pipe product surface precision very high.

The accurate seamless pipe pickling of this detailed description of the invention can adopt sulfuric acid, hydrochloric acid, mixed acid, hydrofluoric acid etc.Carbon structural steels and alloy structure seamless precision seamless pipe should use sulfuric acid washing, carbon constructional quality steel and the accurate seamless pipe of high-quality alloy steel should use chlorohydric acid pickling, should adopt the mixed acid pickling of sulfuric acid, hydrochloric acid and nitric acid containing chromium Cr and the accurate seamless pipe of the higher high-alloy seamless of nickel, the accurate seamless pipe of austenite stainless should use hydrofluoric acid pickling.
Time this detailed description of the invention process-cycle is short, reduces the operations such as middle degreasing, heat treatment, drop-head, aligning, saves the energy, reduces metal consumption, the advantages such as less raw material specification.
The annealing pipe that this detailed description of the invention is produced has the following advantages:
1. the flexibility that precision stainless steel pipe is good, corrosion resistance, high temperature resistant, wear-resistant, pull resistance, water proofing property excellent capability of electromagnetic shielding is provided.2. precision stainless steel pipe can freely bend to various angle and radius of curvature, all has same flexibility and durability in all directions; 3. flexible between precision stainless steel tube coupling distance, there is good retractility, clog-free and stiffness; 4. precision stainless steel pipe respectively saves between the button of limit.
More than show and describe general principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
