Abstract
The invention belongs to the field of surface treatment and relates to a method for clearing glass powder, in particular to a method for clearing glass powder from inner and outer walls of an extruded-state high-end steel tube. The method comprises the following steps of: 1) adding a grinding material into a material mixing tank, adding clean water into the material mixing tank and fully stirring the grinding material to form slurry at the concentration of 30 to 40 percent; 2) placing a tube billet on a riding wheel of a working table, wherein the tube billet does rotating motion and the whole working table does feeding motion; 3) selecting injection pressure and flow according to the material of the steel tube and the attachment degree of the glass powder to the surface; 4) conveying high-pressure water and the slurry to a nozzle respectively by using a high-pressure water pump and a slurry pump and mixing the high-pressure water and the slurry; 5) aligning the nozzle with the inner and outer walls of the steel tube to clear the glass powder from the inner and outer walls of the tube billet; and 6) filtering and screening the cleared slurry and stripped substances, and sending the slurry and the water back to a slurry tank and a water cleaning tank for cycle use.
Description
Technical field
The invention belongs to field of surface treatment, relate to a kind of method of clearing up glass dust, particularly the method for the high-end steel pipe inside and outside wall of cleaning extruding attitude glass dust.
Background technology
Steel pipe is in extrusion process, in order to reduce the frictional force between plug and blank, blank and the recipient, must use glass dust that it is lubricated, but after extruding is finished, glass dust is attached on the inside and outside wall of pipe, extremely difficult cleaning has proposed the method that steel pipe inside and outside wall glass dust is pushed in a kind of effective processing at this situation.
Existing steel pipe inside and outside wall tradition Removal Technology is: (1) pickling.Generally be divided into cathodic pickling and hot acid is washed, Acidwash solution commonly used has sulfuric acid, hydrochloric acid, nitric acid, hydrofluoric acid and various sour mixed liquor.In the acid cleaning process, pickling effect and be a contradiction all the time to the erosion of pipe overpickling occurs and owes the pickling situation through regular meeting; and a large amount of spent acid that in acid cleaning process, produce; the subsequent treatment expense is very high, and expenses of environmental protection is very high, is not inconsistent with national energy-saving and emission-reduction industrial policy.(2) mechanical ball blast, interior mill and dry blasting processing ball blast and dry blasting processing procedure tend to produce very big dust, big for environment pollution, can not remove attachments such as glass dust fully, and the micro-crack on pipe surface can be made up, can not fully expose the microdefect of pipe, also can make the pipe after the processing produce the phenomenon of work hardening, increase the difficulty of processing of subsequent technique.(3) high-pressure water jet cleaning.This mode adopts the high pressure pure water that pipe oxide skin is cleared up, and it is fine that this technology is removed the scale on surface effect for hot pipe, is widely used in each big steel mill.But in the extrusion process because the lubricated attachments such as glass dust that produce, treatment effect is very poor, does not reach technological requirement.
Produce in the process of high-end steel pipe utilizing extrusion process, pipe after the process hot extrusion technique is handled is before carrying out cold-drawing technology, in order to guarantee cold worked surface quality, must dispose the iron scale and the glass dust of steel pipe surfaces externally and internally, and can find the tiny flaw that hollow billet exists.Analyze the prior art condition: above-mentioned three kinds of technologies, all can not satisfy the production requirement of high-end extruding steel pipe.
Summary of the invention
In order to overcome the shortcoming of prior art, the invention provides a kind of method of clearing up the high-end steel pipe inside and outside wall of extruding attitude glass dust,
The present invention includes the following step: 1), abrasive material is added mixing tank, add clear water, fully stirring and forming concentration is 30%～40% slurry; 2), pipe is placed on the workbench support roller and rotates, workbench integral body is done feed motion; 3), according to the degree of steel pipe material and surface attachment glass dust, select expulsion pressure and flow; 4), high-pressure hydraulic pump and mashing pump be transported to the shower nozzle place with water under high pressure and slurry respectively, mix; 5), shower nozzle is aimed at the inside and outside wall of steel pipe, the inside and outside wall glass dust of cleaning pipe; 6), the slurry after cleaning and overburden through recovery system filter, after the screening, respectively with slurry with water is sent slurry tank back to and filtered water tank recycles.
The expulsion pressure in described the 3rd step is 50～70Mpa.
Described abrasive material is garnet, diamond or quartz sand.
The present invention has following advantage: 1, cleaning speed is fast, can effectively clear up glass dust; 2, can realize processing by adjusting pressure to unlike material; 3, can effectively expose the tiny flaw of steel pipe inside and outside wall, avoid the problem pipe to enter next procedure.
The specific embodiment
The present invention includes the following step: 1), abrasive material is added mixing tank, add clear water, fully stirring and forming concentration is 30%～40% slurry; 2), pipe is placed on the workbench support roller and rotates, workbench integral body is done feed motion; 3), according to the degree of steel pipe material and surface attachment glass dust, select expulsion pressure and flow; 4), high-pressure hydraulic pump and mashing pump be transported to the shower nozzle place with water under high pressure and slurry respectively, mix; 5), shower nozzle is aimed at the inside and outside wall of steel pipe, the inside and outside wall glass dust of cleaning pipe; 6), the slurry after cleaning and overburden through recovery system filter, after the screening, respectively with slurry with water is sent slurry tank back to and filtered water tank recycles.The expulsion pressure in described the 3rd step is 50～70Mpa.Described abrasive material is garnet, diamond or quartz sand.
