Abstract
The present invention is composite steel billet producing process, which includes grinding and washing the surface of the base steel layer to be combined and the subsequent superposing and welding.
Description
Technical field:
The present invention is relevant with the preparation method of the steel billet of rolling composite material.
Background technology:
The manufacture method of the composite plate blanks of stainless steel clad plate such as patent No. 01219784.X are disclosed, during fabrication, earlier stainless steel water is cast into the stainless steel layer of the required composite plate thickness of casting one deck 1/3-1/5 thickness in the centrifugal casting machine, be cast into the ordinary carbon steel layer of one deck composite plate thickness 2/3-4/5 thickness again, make composite plate blanks, become stainless steel clad plate through hot rolling.The manufacturing cost height of this composite plate blanks, power consumption is high, and the composite plate gross thickness of making is difficult to make the thin type composite more than 3mm.The easy oxidation of substrate surface, roll forming again after slab need be processed, interface residual stress is big, two-layer between bond strength not high.
Summary of the invention:
The purpose of this invention is to provide a kind of low cost of manufacture, power consumption is few, production efficiency height, bond strength height, the preparation method that can make the composite steel billet of thick shape, thin type composite.
The present invention is achieved in that
The preparation method of composite steel billet of the present invention is cleaned the overlapping composite steel that is welded to connect in back in the composite surface grinding of basic unit's steel.
The cross section of basic unit's steel is that square or rectangle are circular annular or oval.
The cross section of basic unit's steel is rectangle or square or strip, in the one or both sides on its long limit the composite steel that has cleaned is arranged, and two-layer steel overlapping edge position is welded by hand or welded automatically and will be welded to connect all around, bores the aperture exhaust in the commissure of two ends.
The cross section of basic unit's steel is a rectangle or square, all has in its four side and has cleaned composite steel, and two-layer steel overlapping edge position is welded by hand or welded automatically and will weld connection all around, bores the aperture exhaust in the joint edge of two ends.
The cross section of basic unit's steel is circular or oval, basic unit steel cleaning back is pressed on hydraulic press in the tubular composite steel that has cleaned, reach tight fit, weld by hand or weld automatically in two ends more two-layer steel termination knot joint close is welded connection, bore the aperture exhaust in the commissure.
The outer surface of basic unit's steel forms composite steel with band utmost point submerged arc overlay welding with composite steel material strip surfacing to desired height.
The cross section of basic unit's steel is an annular, with the band utmost point submerged arc overlay welding strip surfacing of composite steel material is become composite steel at its outer surface, be pressed into the Composite steel tube or the rod that have cleaned with hydraulic press in the chamber within it and reach tight fit, connect seam crossing by hand or automatically weldering weld connection with two-layer, get out the gas aperture in the commissure.
The cross section of basic unit's steel is an annular, on hydraulic press, be pressed into the Composite steel tube that cleaned or rod iron constitute in composite steel, again basic unit's steel and interior composite steel are pressed into formation outer covering layer steel in the outer composite steel tube that has cleaned on hydraulic press, basic unit's steel and inside and outside composite steel all reach tight fit, the steel billet two ends are connected seam weld or weld automatically connection by hand, in commissure brill aperture exhaust.
The traditional explosion method of method collection of the present invention, welding method, the advantage of roll-bonding method. avoided the shortcoming of traditional handicraft. when rolling, compound interface through grinding increases several times to tens times. and the residual impurity of compound interface is carbonized absorption in heating process simultaneously, large-area fresh interface forms metallurgical binding under mill rolling force, oxidation resistance improves, and joint portion crystal grain improves, and is suitable for the rolling various composites that become with cold-drawn.
The present invention both be suitable for thicker composite blank continuous production and not limited by the production site, also be suitable for the blank production of the composite that approaches.The steel billet of making can be made single double-sided composite plate, the pipe of gross thickness at 0.25mm-16mm, can make the composite steel wire of 0.5mm-5mm, expanded the thin type kind of composition metal, made composite can enter decoration, civil buildings structure, instrument machinery, light textile chemical machinery field.Method of the present invention is fit to continuous productive process, power consumption is few, and technological process is simple, and fabrication cycle is short, and production cost is low, the production efficiency height.Compound cost can be reduced to about 1/10th of traditional handicraft cost.
