Abstract
The invention belongs to steel pipe processing and manufacturing field, specifically a kind of small-bore cold rolled tube inner surface deoiling method, adopt water-soluble washing agent and ultrasonic wave vibration, washed away by inwall sandblasting, remove small-bore cold rolled tube inner surface greasy dirt, its method step is: and charging immersions → ultrasonic wave vibration → inwall solution washes away → first time hot water cleaning → inwall sandblasting washes away → and clean water → second time hot water cleans → inspection.The inwall greasy dirt vibration being immersed in water-soluble washing agent small-bore cold rolled tube is peeled off by the present invention's ultrasonic wave, solution again by circulating washes away, by inwall cleaning oil pollution, then clean respectively with hot water and clear water, finally to inwall spray ceramic sand, inwall is thoroughly cleared up, and cleans up with hot water.The method thoroughly can clear up the greasy dirt of small-bore cold rolled tube inner surface attachment, to prevent from follow-up heat treatment, because of greasy dirt carbonization, causing steel pipe inner wall carburizing problem, and the method environmentally safe, harmless to the material of process.
Description
The application is divisional application, the invention and created name of original application: small-bore cold rolled tube inner surface deoiling method, application number: 201210557280.7, the applying date: 2012-12-20.
Technical field
The invention belongs to steel pipe processing and manufacturing field, specifically a kind of small-bore cold rolled tube inner surface deoiling method.
Background technology
Steel pipe is in cold-rolled process, and the formation rolling greasy dirt that surfaces externally and internally attachment adhesion is stronger, tradition adopts strong acid, or poisonous trichloro-ethylene cleans, and not only has pollution to environment, and easily causes corrosion to material.Have now been developed all kinds of cleaning agent, its deoiling effect is general, cannot clean out especially, directly affect steel duct quality for its inwall greasy dirt of small-bore, longer steel pipe.
Summary of the invention
In order to thoroughly be cleaned out by small-bore cold rolled tube inner surface greasy dirt, the object of this invention is to provide the small-bore cold rolled tube inner surface deoiling method that a kind of deoiling effect is good, environment friendly and pollution-free, do not affect material property.
To achieve these goals, the invention provides a kind of small-bore cold rolled tube inner surface deoiling method, adopt water-soluble washing agent and ultrasonic wave vibration, washed away by inwall sandblasting, repeatedly clear up small-bore cold rolled tube inner surface and reach oil removing object.The present invention is washed away by water-soluble washing agent+ultrasonic wave vibration+inwall sandblasting, and carry out the cleaning of oil removing repeatedly to steel pipe inner wall, reach best deoiling effect, environmentally safe, harmless to material simultaneously.
Described small-bore cold rolled tube inner surface deoiling method, its step comprises: and charging immersions → ultrasonic wave vibration → inwall solution washes away → first time hot water cleaning → inwall sandblasting washes away → and clean water → second time hot water cleans → inspection.
The concrete operations of described step are as follows:
1) charging described in is soaked: cold rolled tube immerses in aqueous cleaning agent container, soaks 2 ~ 5min;
2) the ultrasonic wave vibration described in: start the ultrasonic wave vibration plate installed on the wall, produces the ultrasonic wave vibration of 20 ~ 30KHz frequency, time of vibration 5 ~ 15min;
3) the inwall solution described in washes away: water-soluble washing agent is passed into cold rolled tube wall, washes away inwall, flushing time 5 ~ 10min;
4) the first time hot water cleaning described in: cold rolled tube is put into hot water tank and soaks, and hot water is passed into cold rolled tube wall, inwall is cleaned, scavenging period 5 ~ 10min;
5) the inwall sandblasting described in is washed away: cold rolled tube is put into Sha Chizhong, and the water being mixed with sand is passed into cold rolled tube wall, thoroughly washes away inwall, flushing time 1 ~ 5min;
6) clean water described in: cold rolled tube is put into hot water tank and soaks, and hot water is passed into cold rolled tube wall, inwall is cleaned, scavenging period 5 ~ 10min;
7) the second time hot water cleaning described in: cold rolled tube is put into hot water tank and soaks, and hot water is passed into cold rolled tube wall, inwall is cleaned, scavenging period 5 ~ 10min;
8) inspection described in: got from cold rolled tube wall by band with compressed air, checks cloth clean-up performance.
Described cold rolled tube internal diameter is less than 20mm, and length is greater than 10m.
Advantage of the present invention:
(1) small-bore cold rolled tube inner surface deoiling method of the present invention, with water-soluble washing agent and ultrasonic wave vibration, integrated technology is washed away again with inwall sandblasting, repeatedly clear up small-bore cold rolled tube inner surface, deoiling effect is good, thoroughly can clear up the greasy dirt of small-bore cold rolled tube inner surface attachment, prevent from follow-up heat treatment, because of greasy dirt carbonization, causing steel pipe inner wall carburizing problem;
(2) the present invention is compared with traditional oil removing process, 20mm is less than especially for internal diameter, length is greater than the small-bore cold rolled tube of 10m, and its deoiling effect is best, as being applicable to the abros such as high temperature alloy and Inconel690 such as 18-8 type stainless steel, Incoloy800;
(3) the present invention is compared with traditional oil removing process, environmentally safe, harmless to the material of process.
