Description
Technical field
The invention belongs to steel rolling process field, more particularly to a kind of production method of the stainless steel clad plate of thickness G T.GT.GT 200mm.
Background technology
The composite plate of the two-sided unlike material that stainless steel clad plate is stainless steel to be combined into one and produced by certain way with other steel grades (such as straight carbon steel, the deck of boat, container panel and corrosion-resistant plate, monometallic and alloy), is a kind of to be provided simultaneously with stainless steel and the sheet material with the respective advantage of its composite.Stainless steel clad plate has been widely used for the industries such as oil, chemical industry, salt industry, water conservancy, electric power, and it can be greatly lowered construction costs as a kind of resource-conserving product, inexpensive and high performance perfect adaptation is realized, with good social benefit.The production method of current composite plate rolls heat treating process, molten metal to the substrate jet deposition method of forming and roll-bonding method etc. after mainly having explosive welding composite algorithm, compound casting.Wherein, the roll-bonding method not ambient influnence such as climate, place, transport, and environment will not be polluted, therefore be widely used.The general principle of roll-bonding method is to realize that the technological parameters such as the metallurgical binding of foreign material, clean level, weld strength, the integrality of weld seam, heating-up temperature, soaking time, the drafts of the first passage of its faying face have vital influence to the success rate of method hot rolling under the crunch effect of certain rolling temperature and milling train.
Method hot rolling is topmost sheet material complex technique, and more than 85% is accounted in about 80,000 tons of composite plate yield every year.Composite plate specification is general in 6~200mm, and plate 1000-4400mm wide, plate 14000-20000mm long, substrate can select hot rolled plate (QT：Such as 16Mn) and controlled rolling plate (TMCP：Such as IA85).The production procedure of method hot rolling plate is divided into A methods and B methods：
A methods：The stainless sheet steel being combined the need for the polished treatment of Substrate sheet+faying face of the polished treatment of mating surface+uniform spreading zirconium oxide or the polished basal plate superposition of the stainless steel plate+faying face of chromium oxide powder separation layer+polished treatment of faying face, steel band welded seal is used around two-layer basal plate, vacuumize (deoxygenation is denitrogenated) and then rolled, finally removal sealing steel band, shaping, can once obtain two composite plates.Suitable for the method hot rolling of general thickness basal plate and thin corrosion resistant alloy plate.
B methods：Compound corrosion resistant alloy plate+uniform sacrifice steel plate of zirconium oxide or chromium oxide powder separation layer+surface polishing that spreads is (only as sealing use the need for the Substrate sheet of faying face surface polishing+faying face polishing, discarded after being once finished), steel band welded seal is used around two-layered steel plates, vacuumize and rolled, removal sealing steel band, shaping, once can only obtain a composite plate；It is compound with corrosion resistant alloy thin plate suitable for special heavy plate (thickness is more than 200mm) substrate.Method hot rolling plate feature：Composite bed is combined uniformly with substrate, and peel strength is typically larger than 140MPa；But the product such as pipe fitting, vessel head etc. for particular/special requirement require method hot rolling plate of the peel strength more than 280MPa, bond strength is generally increased using methods such as composition surface nickel plating.
The content of the invention
The present invention is intended to provide one kind can both fix stainless steel plate orientation, arc blow phenomenon can be eliminated again, realize once producing two pieces of stainless steel clad plates, be suitable for the production method of the special thickness composite plate of stainless steel of industrialized production.
Therefore, this invention takes following technical solution：

(2) after by the rusty scale on all faces of compound stainless steel plate and oxide layer removal, finely polish and dry up, it is then uniform on two plots of composite surfaces of compound stainless steel plate to dispense zirconium oxide or chromium oxide powder separation layer；
(3) prepare two pieces of Q235B base bases, and the composite surface of base base and side are polished, is polished；
(4) nested plates are used into stainless steel plate size according to compound, with middle part as symmetric points, cuts out nesting corresponding with compound use stainless steel plate size, length and width size precision is controlled within+2mm；
(5) nesting is positioned on base base, after external dimensions alignment, the composite surface that two pieces of compound stainless steel plates are dispensed again have zirconium oxide or chromium oxide powder separation layer is overlayed in nesting relatively, another piece of base base is covered in above compound stainless steel plate again finally, external dimensions is alignd, and the gap of commissure is not more than 2mm after assembly；
(6) composite billet after assembly is entered into vacuum chamber to be vacuumized, after vacuumizing, start to patrol edge point weldering, patrol side amendment step-length no more than 100mm, electron beam middle part correspondence is in welded joints, it is with linear spot welding small routine that base base is spot-welded together with nested, two no more than 1 meter of solder joint distances, the depth of weld is not less than 20mm；
(7) patrolling again behind side carries out sequential welding and connects, and fusion penetration is not less than 40mm, and base base is firm integrally welded with nested；
(8) it is heat-treated and is rolled after welds, after rolling, the steel plate of nested parts is cut away, remaining part composite plate will naturally be separated between spreading zirconium oxide or two pieces of stainless steel plates of chromium oxide powder separation layer, so as to can once obtain two special thickness composite plates of the stainless steel of two-sided unlike material.
Beneficial effects of the present invention are：
Present invention process is simple, and assembly is fast, can not only avoid arc blow phenomenon during welding between stainless steel and carbon steel, weld penetration is ensured, fully effective can be combined between stainless steel and carbon steel；And two pieces of spy's thickness stainless steel clad plates of two-sided unlike material can be once produced, production efficiency is high, is capable of achieving large-scale industrial production, solves the low technical barrier of stainless steel clad plate production capacity.The country also in blank is produced particularly with the special thickness composite plate of vacuum, with larger reference.
