The specific embodiment:
Embodiment one
The production technology of steel pipe is seen Fig. 1 to 3, and it may further comprise the steps:
Cutting processing, according to the steel plate 1 that the circumference and the length of printing plate cylinder cuts out respective width size and length dimension, the little 8～18.5mm of circumference of the steel pipe that the width of steel plate 1 forms than being curled by steel plate 1, the length of steel plate 1 and the length of steel pipe are complementary; Because the steel pipe that steel plate 1 bending forms will be reserved a weld seam, add the certain thermal expansion distortion of steel pipe meeting generation after the process welding processing that bending is come out, therefore, make the circumference little 8～18.5mm of the width of steel plate 1 than the printing plate cylinder of design processing, the diameter of the steel pipe that processes just is a bit larger tham the diameter of the printing plate cylinder that will design processing, the precision of the diameter of the steel pipe that assurance is produced, the allowable error of diameter of steel tube is less than 0.1mm, and steel pipe is delaying work difference less than 0.01mm through allowing behind the correct grinding.
Wherein, the first, steel plate 1 selects for use phosphorus content to be lower than 2 ‰ low carbon steel plate 1 material, and phosphorus content is lower than 2 ‰ steel plate 1 and is convenient to carry out cold working and welding processing, reduces the technical difficulty of processing, cut down finished cost, and the yields height; The second, steel plate 1 is selected the thick low-carbon steel plate of 5～12mm for use, and the low-carbon steel plate thickness that 5～12mm is thick is moderate, it not only can process steel pipe, can guarantee simultaneously the structural strength and the machinability of steel pipe, and can well-known phrase reduce the weight of steel plate 1 to greatest extent, reduce cost.
Curl and process, carry out roll extrusion repeatedly by 2 pairs of steel plates of three roller rolling machines 1, have three pressure rollers on the three roller rolling machines 2, being positioned at pressure roller topmost is top roll 2a, three pressure rollers are crooked and be rolled into the steel pipe pipe of cylindrical shape with steel plate 1, the roll extrusion number of times is advisable with 3 to 10 times, as long as steel plate 1 is curled into cylindrical shape, the roll extrusion number of times is many more, the steel plate 1 curling steel pipe pipe that forms approaches cylinder more, Deformation control to the steel pipe pipe is good more, further guarantees the roundness and the cylindricity of steel pipe pipe, and the phenomenon of ellipse or local deformation can not appear in the steel pipe pipe; Joint on the steel pipe pipe forms a weld seam 3, and the width of the weld seam 3 of formation is 3～3.5mm, and the width of weld seam 3 is unsuitable excessive or too small, and weld seam 3 is difficult to realize welding processing when excessive, and scolder was difficult to fully weld seam 3 be filled up when weld seam 3 was too small.
Wherein, the top roll 2a of three roller rolling machines is divided into three sections of left end district 1a, mesozone 1b and right-hand member district 1c, left end district 1a and right-hand member district 1c are symmetrically distributed in the both sides of mesozone 1b, the diameter of left end district 1a or right-hand member district 1c is the trend of dwindling from inside to outside, and left end district 1a and right-hand member district 1c account for 1/3rd of top roll 2a respectively on length.Because the rectangular steel plate 1 of standard is after being curled into cylindrical shape, equipment in being processed, steel plate 1 self stress and factor affecting such as distortion because of curling and causing, each regional diameter of the steel pipe that curls out is unequal, the diameter of steel pipe becomes big from middle gradually to two ends, therefore, the steel pipe that curls out has only the diameter of zone line and estimates that the diameter that processes steel pipe is consistent, and the diameter at two ends is all greater than the diameter of estimating to process steel pipe.Because the left end district 1a of the top roll 2a of three roller rolling machines of the present invention and the diameter of left end district 1a are the trend of dwindling from inside to outside, balance is to the extruding force of steel plate, the steel plate 1 that cutting is come out just can become the cylinder form of a standard behind the process cans, each regional diameter of the steel pipe that curls out equates.Production technology of the present invention is ingenious and solved this problem effectively, each the regional diameter of steel pipe that processes is equated, therefore, steel pipe can be applied to various fields, the occasion that particularly steel pipe is had high-precision requirement, steel pipe of the present invention can replace seamless steel pipe in many instances, and for example the roll body as printing plate cylinder uses.
Welding processing is carried out welding processing to the joint of steel pipe pipe, and scolder is filled the weld seam 3 of full joint, is connected together by two side welds of welding processing with weld seam 3; Wherein, the selecting the application scenario of looking steel pipe for use of welding wire and solder flux and selecting.For example, the roll body of steel pipe as printing plate cylinder used, and for most scolder, it is very difficult realizing electroplating processing at scolder that there are the quality problems of each side in electroplating effect extreme difference, electrodeposited coating; Therefore, for the scolder that makes weld seam 3 places has similar characteristic to steel plate 1, on scolder, can realize electroplating processing, guarantee that simultaneously electrodeposited coating has higher quality, for example carry out copper facing processing, chromium plating processing or zinc-plated processing on scolder, can form even and continuous high-quality copper plate, chromium coating or the zinc coat of a layer thickness on all at steel pipe and scolder after the plating, the present invention is in electric welding processing, welding wire is selected welding wire for submerged-arc welding H08A for use, and solder flux is selected for use No. 431.In addition, also sand holes or crack can not occur in the scolder that the welding back forms, it guarantees that steel pipe can not split at a high speed and in the hyperbaric environment.
Rounding processing is carried out the processing of car mill by car mill equipment to the steel pipe pipe, and the redundance between the diameter of removal steel pipe pipe and printing plate cylinder makes the face of cylinder of steel pipe pipe become a continuous cylinder curved surface; Rounding processing comprises the turning processing of carrying out in order, the processing of rough turn mill and the processing of accurate car mill.
The steel pipe finished product.
The steel pipe that the present invention produces performance in every respect all approaches the performance of seamless steel pipe, and steel pipe's production is simple, therefore, the steel pipe that the present invention produces can replace seamless steel pipes in various fields, reduce cost, and its length and diameter can be set according to the actual requirements, be not subjected to the restriction of dimensions, therefore, it can save the steel use amount significantly, further saves cost.
