Abstract
The invention relates to a degreasing process of stainless steel pipes, which is characterized in that the process comprises: immersing the steel pipe with grease into the oil groove with common kerosene; taking out the steel pipe after a period and draining off most of the oils on the steel pipe by inclined setting the steel pipe; placing the steel pipe on a cleaning frame and stuffing the cotton yarns dipped with a little butyl acetate or acetone into one end of the steel pipe; blowing at the inside of the steel pipe from the end of the steel pipe which is stuffed with cotton yarns using undefiled compressed air until blowing off and wiping the internal wall of the steel pipe; scrubbing the external wall of the steel pipe by the cotton yarns dipped with a little butyl acetate or acetone until cleaning the steel pipe. Utilizing the cheap common kerosene as the main materials in the degreasing process instead of expensive organic solvents, the degreasing process improves the cleaning ability and speed, reduces the production cost and increases operation convenience, and besides the materials are harmless to the human body and has no pollution to the environment, so the degreasing process can be operated in an open environment. After repeated use, the waste kerosene the effect of which is reduced can be used as fuels or carried to oil refineries for collecting and recycling.
Description
Technical field
The present invention relates to a kind of method of removing the greasy dirt on the metal, specifically relate to a kind of degreasing process of stainless steel tube.
Background technology
At present, making stainless steel tube, especially in making accurate seamless stainless steel pipe process, using a large amount of commercial greases repeatedly as lubricated and cooling agent.Because arts demand, the steel pipe of this band grease can not enter down the road heat treatment step, and degreasing is the success or failure of decision precision stainless steel pipe quality, and finished product can not be with oil to dispatch from the factory.Thereby degreasing is an important procedure in the whole process of production.
What traditional degreasing process was widely adopted roughly has two kinds: the one, adopt nitric acid (10-15%)+hydrofluoric acid (5-10%).This acid has strong impulse and corrosivity, and operating condition is very abominable, and is very big to human body and ambient influnence.The 2nd, adopt organic solvent toluene+dimethylbenzene+surfactant, embathe earlier, again with a large amount of clear water flushings.The liquid waste processing difficulty of this class organic solvent is very big, and the poisonous washing waste liquid as milk can not directly discharge in a large number, and the treatment facility investment is expensive! And organic solvent itself is also more expensive!
Summary of the invention
Be to solve the deficiencies in the prior art, the object of the present invention is to provide the degreasing process of the stainless steel tube of a kind of economy, efficient, environmental protection, effectively remove the grease on the stainless steel tube.
For achieving the above object, the present invention is achieved by the following technical solutions:
A kind of degreasing process of stainless steel tube is characterized in that technical process comprises:
(1), embathes: the steel pipe of band grease is immersed the oil groove that injects common kerosene;
(2), embathe certain hour after, steel pipe is taken out, tilting drop removes most fluid on the steel pipe;
(3), steel pipe is placed on the rack for cleaning, dip in little acetic acid fourth fat with cotton yarn or acetone is filled in steel pipe one end;
(4), blow in steel pipe from the end that steel pipe is filled in cotton yarn repeatedly, blow the wiping cleaning until the steel pipe inwall with the compressed air of clean (not having oily, anhydrous, dustless);
(5), dip in an amount of butyl acetate or acetone scouring steel pipe appearance with cotton, until cleaning.
The degreasing process of aforesaid stainless steel tube is characterized in that in described oil groove bottom supersonic generator being housed also.
The invention has the beneficial effects as follows: the present invention uses cheap common kerosene (6000 yuan per ton approximately) to replace expensive organic solvents (25000 yuan per ton approximately) as the primary raw material in the degreasing process, improve cleansing power and cleaning speed, also reduce production cost, strengthened operation convenience; And harmless, the environmentally safe of raw material used in the present invention can be operated in open environment, and the waste coal oil that uses the back effect to descend repeatedly not only can be done the fuel oil use but also can send the oil plant reclaiming.
The specific embodiment
Below technology of the present invention is carried out concrete introduction.
Making stainless steel tube, especially make in the process of accurate seamless stainless steel pipe, before heat-treating operation, need carry out degreasing process.The concrete operating process of the present invention is:
1, embathes: the steel pipe of band grease is immersed the oil groove that injects common kerosene, utilize kerosene dissolving commercial grease;
2, embathe certain hour after, steel pipe is taken out, tilting drop removes most fluid on the steel pipe;
3, steel pipe is placed on the rack for cleaning, dips in little acetic acid fourth fat or acetone is filled in steel pipe one end with cotton yarn;
4, blow in steel pipe from the end that steel pipe is filled in cotton yarn repeatedly with the compressed air of clean (not having oily, anhydrous, dustless), blow the wiping cleaning until the steel pipe inwall;
5, dip in an amount of butyl acetate or acetone scouring steel pipe appearance with cotton, until cleaning.
The kerosene organic solvent of comparing wants much cheap, and cleaning performance is also fine, to human body, environmentally friendly, satisfies environmental protection requirement, has reduced production cost, and kerosene can recycle, to operation is very easy.
In addition, when degreasing, also can install high-power ultrasound generator in the oil groove bottom and carry out ultrasonic concussion, can improve cleaning performance.Simultaneously, when producing in enormous quantities, can make the automation cleaning machine, further increase work efficiency.
The foregoing description does not limit the present invention in any form, and all employings are equal to the technical scheme that mode obtained of replacement or equivalent transformation, all drop in protection scope of the present invention.
Claims (2)
1, the degreasing process of stainless steel tube is characterized in that technical process comprises:
(1), embathes: the steel pipe of band grease is immersed the oil groove that injects common kerosene;
(2), embathe certain hour after, steel pipe is taken out, tilting drop removes most fluid on the steel pipe;
(3), steel pipe is placed on the rack for cleaning, dip in little acetic acid fourth fat with cotton yarn or acetone is filled in steel pipe one end;
(4), blow in steel pipe from the end that steel pipe is filled in cotton yarn repeatedly, with clean compressed air until the steel pipe inwall blow wipe clean;
(5), dip in an amount of butyl acetate or acetone scouring steel pipe appearance with cotton, until cleaning.
2, the degreasing process of stainless steel tube according to claim 1 is characterized in that in described oil groove bottom supersonic generator being housed also.
