The invention discloses a kind of Rolling compund method of stainless steel clad plate, the composite surface of female base is surface-treated by it, then docking relative with the composite surface of stainless steel billet, then two blank materials are welded as a whole, composite billet is constituted, composite plate blanks are finally rolled into described composite plate.When being rolled using this method, composite bed is directly contacted with milling train, stress（Inwardly, roll-force transfer capability is poor for the general surface stainless steel of symmetrical sandwich）, therefore composite surface performance will get well, and realize the production for the steel plate that more than width 3000mm and/or shear strength more than 350Mpa special dimension is used.More than the shear strength 350Mpa of stainless steel clad plate obtained by this method, composite bed flaw detection can close I grades of forging, excellent combination property；Available for fields such as nuclear power, pipeline, production platform, elevated temperature vessel steel plates.
Description
Technical field
The present invention relates to a kind of production method of composite plate, the Rolling compund method of especially a kind of stainless steel clad plate.
Background technology
Clad steel plate as a kind of new economical material, it is low in steel market in the case of, will increasingly by
People are to attention, and its application also will more and more extensively, and the market demand also will be in rising trend.China's clad steel plate sale class
It is mainly stainless steel clad plate in type, accounts for more than the 80% of total amount, it is widely used in its people's warp such as oil, chemical industry, salt manufacturing alkaline
In Ji and all trades and professions.
The mode of country's stainless steel clad plate production has three kinds at present, roll-bonding method, explosion composite method and " blast+
Rolling " composite algorithm.Explosive clad plate when producing can environment pollute, production cost is high, low production efficiency and rolling composite plate
Because production technology and production equipment require high, it is desirable to have large-scale steel mill does support and could produced, so manufacturer is less, rolls
The advantage of composite plate processed is that speed of production is fast, the most long 13000mm of the production most wide 2500mm of plate width.Answer for most notable 3 in the world
Plywood Chang Doushi rolling composite plates factory, as the JFE of Japan, there be the VAI of Austria the Bethlehem in the U.S..
In the process aspect of Rolling Production stainless steel clad plate, domestic manufacturer is much using the method system of symmetry rolling
Base, this is due to that single base is combined that base is very high to equipment requirement, complex process is caused.Symmetrical blank-making method is fairly simple, still
Rolled products performance is not high, and steel plate width is mainly used in the product for civilian use in below 2800mm, it is impossible to be used in production nuclear power, oil recovery
The high-end fields such as platform, wind-powered electricity generation plate, these high-end fields are to composite surface Percentage bound requirement 100%, and shear strength index exists
More than 350Mpa.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of Rolling compund side of the high stainless steel clad plate of shear strength
Method.
In order to solve the above technical problems, the technical solution used in the present invention is：The composite surface of female base is carried out at surface
Reason, then docking relative with the composite surface of stainless steel billet, then two blank materials are welded as a whole, constitutes composite billet, finally will be compound
Slab is rolled into described composite plate.
The composite surface surface treated of female base of the present invention is to roughness in 2~5um.
The butt seam of two composite surface of the present invention is at 20 and following.
The solder joint that four edge points weldering length of two blank material of the present invention is 200mm, solder joint layer depth is not less than 35mm.Institute
2 weldings are used when stating welding；First time, weld heat input was in 86~110KJ/cm3, speed of welding is 250~300mm/s；
Second of welding energy is in 135~160KJ/cm3, speed of welding is 150~200mm/s.
Hot rolling of the present invention is：Composite plate blanks are heated to 1200~1240 DEG C, are incubated 3~6 hours, then roll.
It is using the beneficial effect produced by above-mentioned technical proposal：During using present invention rolling, composite bed is directly with rolling
Machine contact, stress（Inwardly, roll-force transfer capability is poor for the general surface stainless steel of symmetrical sandwich）, therefore composite surface performance will get well,
Realize the production for the steel plate that more than width 3000mm and/or shear strength more than 350Mpa special dimension is used.The present invention
More than the shear strength 350Mpa of gained stainless steel clad plate, composite bed flaw detection can close I grades of forging, excellent combination property；It can use
In fields such as nuclear power, pipeline, production platform, elevated temperature vessel steel plates.
