Abstract
The invention belongs to the field of steel pipe machining and manufacturing, in particular to a minor-caliber cold rolling pipe inner surface oil removing method. Water-soluble cleaning agents and ultrasonic vibration are adopted, and oil contamination on a minor-caliber cold rolling pipe inner surface is removed by inner wall sand blasting and washing. The method comprises the steps of material filling and steeping, ultrasonic vibration, inner wall solution washing, the first time hot water cleaning, inner wall sand blasting and washing, clear water cleaning, the second time hot water cleaning and inspection. According to the method, the oil contamination, which is steeped in the water-soluble cleaning agents, on the minor-caliber cold rolling pipe inner surface is separated in a vibration mode through ultrasonic waves and is then washed through solutions which flow in a circulation mode, the oil contamination on the inner wall is cleaned, cleaning is carried out through hot water and clear water respectively, finally ceramic sand spraying is carried out on the inner wall, thorough cleaning is carried out on the inner wall, and the inner wall is cleaned through the hot water. According to the method, the oil contamination attached to the minor-caliber cold rolling pipe inner surface can be cleaned thoroughly, the problem that the inner wall of a steel pipe is carburized due to the fact that the oil contamination is carbonized in subsequent heat treatment is prevented, and the environment is free of pollution and treated materials is free of damage because of the method.
Description
The application is divisional application, the invention and created name of original application: small-bore cold rolled tube inner surface deoiling method, and 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 surfaces externally and internally adheres to the formation rolling greasy dirt that adhesion is stronger, and tradition adopts strong acid, or poisonous trichloro-ethylene cleans, and not only environment is had to pollution, and material is easily caused to corrosion.Developed at present all kinds of cleaning agents, its deoiling effect is general, cannot clean out especially for its inwall greasy dirt of small-bore, longer steel pipe, directly affects steel duct quality.
Summary of the invention
For small-bore cold rolled tube inner surface greasy dirt is thoroughly cleaned out, 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 vibration, wash away by inwall sandblast, repeatedly clear up small-bore cold rolled tube inner surface and reach oil removing object.The present invention washes away by the sandblast of water-soluble washing agent+ultrasonic vibration+inwall, and steel pipe inner wall is carried out to the cleaning of oil removing repeatedly, reaches best deoiling effect, and environmentally safe, harmless to material simultaneously.
Described small-bore cold rolled tube inner surface deoiling method, its step comprises: the wash away → clean → clean → inspection of hot water for the second time of wash away → clear water of hot water cleaning → inwall sandblast for the first time of charging immersion → ultrasonic vibration → inwall solution.
The concrete operations of described step are as follows:
1) described charging is soaked: cold rolled tube immerses in aqueous cleaning agent container, soaks 2～5min;
2) described ultrasonic vibration: start the ultrasonic wave vibration plate being arranged on chamber wall, produce the ultrasonic vibration of 20～30KHz frequency, time of vibration 5～15min;
3) described inwall solution washes away: water-soluble washing agent is passed into cold rolled tube wall, inwall is washed away, flushing time 5～10min;
4) described hot water for the first time cleans: cold rolled tube is put into hot water tank and soak, and hot water is passed into cold rolled tube wall, inwall is cleaned, scavenging period 5～10min;
5) described inwall sandblast is washed away: cold rolled tube is put into Sha Chizhong, and the water that is mixed with sand is passed into cold rolled tube wall, inwall is thoroughly washed away, flushing time 1～5min;
6) described clear water cleans: cold rolled tube is put into hot water tank and soak, and hot water is passed into cold rolled tube wall, inwall is cleaned, scavenging period 5～10min;
7) described hot water for the second time cleans: cold rolled tube is put into hot water tank and soak, and hot water is passed into cold rolled tube wall, inwall is cleaned, scavenging period 5～10min;
8) described inspection: with compressed air, band is got from cold rolled tube wall, checked 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, by water-soluble washing agent and ultrasonic vibration, wash away integrated technology with inwall sandblast again, repeatedly clear up small-bore cold rolled tube inner surface, deoiling effect is good, can thoroughly clear up the greasy dirt that small-bore cold rolled tube inner surface adheres to, 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, be less than 20mm for internal diameter especially, length is greater than the small-bore cold rolled tube of 10m, its deoiling effect the best, as be 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, and environmentally safe is harmless to the material of processing.
