Abstract
The invention relates to a method for preparing a complete anticorrosive coating on the inner surface of a steel closed container. The method comprises the following steps of: making a steel closed container; equally cutting the steel closed container into two halves; welding a quarter of a longitudinally cut steel pipe at the two sides of the cut respectively, wherein after the two half containers are combined, the two quarters of the longitudinally cut steel pipe just form a half round pipe; thermally spraying anticorrosive coatings on the inner surface of the container and the outer surface of the steel pipe; making a groove on the outer surface of the cut, and welding all parts while reserving a small hole at the top; filling thermit welding flux along the reserved small hole, and igniting the thermit welding flux, wherein the generated molten iron flows to the bottom and fills the bottom of the half round steel pipe, and the reaction product aluminum oxide forms a ceramic coating on the pipe wall; and firmly welding the reserved small hole with a metal ceramic welding rod, thereby finishing the preparation of the complete anticorrosive coating on the inner surface of the container. Through the invention, a complete anticorrosive coating can be prepared on the inner surface of the steel closed container, thus the corrosion resistance of the container is improved, and the service life of the container is prolonged; and the process is simple and easy to operate and has strong reliability.
Description
Technical field
The present invention relates to a kind ofly prepare complete anticorrosion coating method at steel closed container inside face.The metal surface field of engineering technology.
Background technology
The steel closed container is widely used in fields such as oil, chemical industry.But the preparation problem of the complete anticorrosion coating of its inside face does not have good solution so far.Difficult point is if adopt in advance after inside face prepares coating welding forming operation again, or the back that is shaped enters in the container at the reserved opening place, adopts technology such as thermal spraying to prepare anticorrosion coating, all can't carry out anti-corrosion treatment to last one weld seam.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, providing a kind of can prepare complete anticorrosion coating method at steel closed container inside face.
The object of the present invention is achieved like this: a kind ofly prepare complete anticorrosion coating method at steel closed container inside face, described method comprises following processing step:
Step 1, make the steel closed container with prior art;
Step 2, the steel closed container that step 1 is made are cut into impartial two halves;
Step 3, each welding is gone up by the steel pipe that vertically is split into 1/4th along the described otch of step 2 both sides, its curvature is identical with described container inner wall, be close to container inner wall welding, after reaching the two halves container and merging, 1/4th steel pipes of two vertical subdivisions just in time synthesize half pipe;
Step 4, in the outer surface heat anticorrosion with painting coating of described inner surface of container and steel pipe;
Step 5, beat groove, except that an osculum is reserved at the top,, make container become an integral body again all the other position seam at the outside face of incision;
Step 6, the suitable osculum of reserving are inserted aluminum heat flux, aluminum heat flux ignites, thermit reaction takes place in semicircle steel pipe, the molten iron that generates flows to the bottom and fills the semicircle steel pipe, the resultant of reaction alundum (Al is hung on tube wall and forms cramic coat, the result is equivalent to prepare cramic coat with the static self-spreading method at semicircle steel pipe inwall, and this coating plays last one weld seam of protection and avoids corroding;
Step 7, the dead osculum of reserving of usefulness metal ceramics welding rod weldering are finished the preparation of the complete anticorrosion coating of described inner surface of container.
Employing the invention has the beneficial effects as follows:
1, can prepare complete anticorrosion coating at steel closed container inside face, improve container antiseptic power and service life;
2, simple, the easy operating of technology, good reliability.
The specific embodiment
The present invention relates to a kind ofly prepare complete anticorrosion coating method at steel closed container inside face, described method comprises following processing step:
Forming techniques such as step 1, the existing welding of employing or dieless bulging ball are made the steel closed container.
Step 2, the steel closed container of step 1 being made with metal cutting method commonly used are cut into impartial two halves.
Step 3, each welding is gone up by the steel pipe that vertically is split into 1/4th along the described otch of step 2 both sides, its curvature is identical with described container inner wall, be close to container inner wall welding, after reaching the two halves container and merging, 1/4th steel pipes of two vertical subdivisions just in time synthesize half pipe.
Step 4, prepare anticorrosion coating at the outside face of described inner surface of container and steel pipe with existing ripe plasma spray technology (high speed oxygen acetylene torch spraying technology).
Step 5, beat groove, except that an osculum is reserved at the top,, make container become an integral body again all the other position seam at the outside face of incision.
Step 6, suitable osculum are inserted aluminum heat flux (granularity is 200 orders), until filling up.Thermit reaction takes place in the aluminum heat flux that ignites in semicircle steel pipe, the molten iron of generation flows to the bottom and fills semicircle steel pipe bottom, and the resultant of reaction alundum (Al is hung on tube wall and forms cramic coat.The result is equivalent to prepare cramic coat with the static self-spreading method at semicircle steel pipe inwall.This coating plays last one weld seam of protection and avoids corroding.
Step 7, with having anti-corrosion function, can forming the dead osculum of reserving of metal ceramics welding rod weldering of metallurgical binding with metal again, finish the preparation of the complete anticorrosion coating of described inner surface of container.
Claims (1)
1. one kind prepares complete anticorrosion coating method at steel closed container inside face, and it is characterized in that: described method comprises following processing step:
Step 1, make the steel closed container;
Step 2, the steel closed container that step 1 is made are cut into impartial two halves;
Step 3, each welding is gone up by the steel pipe that vertically is split into 1/4th along the described otch of step 2 both sides, its curvature is identical with described container inner wall, be close to container inner wall welding, after reaching the two halves container and merging, 1/4th steel pipes of two vertical subdivisions just in time synthesize half pipe;
Step 4, in the outer surface heat anticorrosion with painting coating of described inner surface of container and steel pipe;
Step 5, beat groove, except that an osculum is reserved at the top,, make container become an integral body again all the other position seam at the outside face of incision;
Step 6, the suitable osculum of reserving are inserted aluminum heat flux, aluminum heat flux ignites, thermit reaction takes place in semicircle steel pipe, the molten iron that generates flows to the bottom and fills semicircle steel pipe bottom, the resultant of reaction alundum (Al is hung on tube wall and forms cramic coat, and the result is equivalent to prepare cramic coat with the static self-spreading method at semicircle steel pipe inwall;
