Abstract
The invention relates to a production method and device for manufacturing a composite pipe from a composite stainless steel plate by hot rolling. The production method comprises the forming process of the pipe and the welding process of the pipe. The invention is characterized in that in the forming process of the pipe, a carbon steel/stainless steel composite metal plate is bent into a pipe shape; and in the welding process of the pipe, a high-frequency welding method is adopted to closely weld carbon steel joint edges on the pipe-shaped joint edges together, and then an argon-arc and wire-feed filling welding method is adopted to closely weld stainless steel joint edges on the pipe-surface-shaped joint edges together. Compared with the prior art, the invention has the advantages that no gaps exist between pipe layers, the process is simple and the production cost is low.
Description
Technical field
The present invention relates to a kind of production method and device of hot-rolled stainless steel compound pipe molding welding.
Background technology
The production method of existing composite metal pipe comprises makes the core pipe earlier, and then past core tube outer surface coats cladding material and this cladding material is welded into tubulose, the greatest drawback that above-mentioned technology exists is to leave the space between two-layer pipe, water and air infiltrates space internal corrosion pipe easily, and, this kind technical matters complexity, the production cost height.
Summary of the invention
The goal of the invention of this hot-rolled stainless steel clad steel plate moulding welding invention is to provide the production method and the device of the multiple tube that hot-rolled stainless steel clad steel plate very close to each other, that technology is simple, production cost is low is made between a kind of layer of pipe.
The present invention is to realize like this by the production method of the multiple tube that hot-rolled stainless steel clad steel plate moulding welding is made, comprise the forming process of pipe, the welding process of pipe, its special feature is that the forming process of pipe is that the stainless compound steel plate that hot rolling is good twists into tubulose, the welding process of pipe is to adopt the high-frequency welding method that the carbon steel jointing edge on the tubulose jointing edge is closely welded together earlier, adopts argon arc to add the wire feed welding method then the stainless steel jointing edge on the tubulose jointing edge is closely welded together.Because the temperature of carbon steel welding is low more than the temperature of stainless steel welding, is to magnetize welding at high-frequency welding process medium carbon steel under 200～250 hertz of frequencies, and stainless steel is not magnetizable welding, can only carry out the welding second time to stainless steel composite pipe, just stainless steel parts be welded.
If the full argon arc that adopts welds, though can both be with carbon steel and stainless steel welding, but, contained ferrite can be exuded in the stainless steel weld joint and the surface after the carbon steel welding, and ferritic existence makes stainless steel weld joint and surface easily form oxidizing electrode and corrosion has seriously influenced the quality and the use of composite pipe.Adopt the technology of the present invention just to solve the problems referred to above well, adopt the high-frequency welding method welding carbon steel of relative low temperature earlier, at this moment, because stainless steel does not also have fusion weld, therefore, even carbon contained after the carbon steel fusion can ooze out, stainless steel welding after also can not influencing, adopt argon arc to add the wire feed welding method, owing to be the stainless steel melt of in weld seam, filling fusion, like this, the ferrite of the carbon steel weld below the stainless steel weld joint is released on the stainless steel weld joint, has guaranteed the quality of composite pipe.
Here, add wire feed when welding in order further to guarantee argon arc, the metal of high-temperature fusion can not make the ferritic steel fusion and disengage carbon in stainless steel melt, just carries out argon arc in 3-20 seconds after the high-frequency welding and adds wire feed and weld.Like this, the carbon steel after the high-frequency welding can obtain cooling to a certain degree, gets the high-temperature fusant molten carbon steel when wire feed welds thereby avoided argon arc to add effectively.
The process units of the multiple tube of being made by hot-rolled stainless steel clad steel plate moulding welding of the present invention is to realize like this, comprise the transport sector of band plate successively, band plate twisted into shaping mechanism, the welding mechanism of pipe, the post processing mechanism of the pipe of tubulose, its special feature is that the welding mechanism of pipe comprises that successively high-frequency welding equipment, argon arc add the wire feed welder, adds the typing transfer roller that is provided with pipe between the wire feed welder at high-frequency welding equipment, argon arc.During work, the transport sector of band plate is transported to hot-rolled stainless steel composite steel band (plate) band plate is twisted on the shaping mechanism of pipe of tubulose, the shaping mechanism that band plate is twisted into the pipe of tubulose twists into tubulose with hot-rolled stainless steel composite steel band (plate), deliver to then on the welding mechanism of pipe, high-frequency welding equipment welds the carbon steel joint close of pipe earlier on the welding mechanism of pipe, add of the stainless steel joint close welding of wire feed welder by argon arc afterwards, deliver to post processing mechanism afterwards and carry out weld grinding, sizing, cut pipe.
Here, the Han Jie ∕ wire feed point that argon arc adds the wire feed welder be positioned at the pipe joint close above, such setting just can processing stainless steel be positioned at the composite pipe of the outer surface of pipe.Perhaps, the Han Jie ∕ wire feed point that argon arc adds the wire feed welder be positioned at pipe the pipe joint close below, such setting just can processing stainless steel be positioned at the composite pipe of the inner surface of pipe.
Therefore the present invention, has advantage very close to each other, that technology is simple, production cost is low between layer pipe owing to adopt the two-stage welding manner.
