Description

A kind of manufacture method of stainless steel clad plate
Technical field
The present invention relates to a kind of manufacture method of stainless steel clad plate, belong to composite metal plate manufacturing process technology field.
Background technology
Layered metal composite material is to be formed by two-layer or two-layer above metal composite of different nature, and it possesses the original not available good characteristic of each homogenous material.By to the choose reasonable of laminate component and suitable processing technology, can obtain the laminated-metal composite that meets different needs, also can utilize cheap base layer metal to substitute expensive composite bed metal, to reduce costs.Comprise: Stainless Steel Steel Clad Plate, copper-steel composite board, Complex plate of aluminum and steel, titanium-steel composite board etc.Stainless steel clad plate is a kind of modal, purposes metallic composite the most widely, it retains stainless corrosion-resistant, the performance such as wear-resisting, diamagnetic and specious feature, again with the feature of the good solderability of carbon steel, formability, draftability, thermal conductivity, can be widely used in the fields such as metallurgy, shipbuilding, aerospace, pharmacy, food, building, electronics, chemical industry, machinery, national defence.
At present, several production methods that stainless steel clad plate is conventional have: soldering composite algorithm, blast composite algorithm, explosive welding rolling and Direct Rolling method.Soldering composite algorithm is that solder is placed between plied timber and parent metal, by heating after-applied pressure, the method that multiple layer and parent metal are combined, the method is simple to operate, but the composite plate bond strength of preparation is not high, is applicable to the less demanding composite metal plate of combined strength bination; It is compound that blast composite algorithm can make metal moment that two kinds of fusing point difference are very large complete, and avoided interface to generate intermetallic compound, but the composite plate size that the method is produced is less and plate shape is poor, unstable product quality, energy consumption is large, contaminated environment, and lumber recovery is low; Explosive welding rolling is to adopt blast base, the method of recycling hot rolling unit roll forming, owing to being subject to quick-fried restriction of rolling composite blank specification, its product specification is also limited, also brought in addition the consumption of shooter artistic skill large, the shortcomings such as production efficiency is low, contaminated environment.
Recent years, the Direct Rolling method of stainless steel clad plate became the focus of research, the vacuum milling method of a kind of composite metal plate that Chinese Patent Application No. CN201110270155.3 discloses, the method comprises following main technique: (1) substrate processing ring chamfering groove: corrosion resistant plate peripheral size is less than substrate ring week chamfering groove size; (2) boring: bore hole, a right angle as vacuumizing hole on substrate; (3) preposition butt welding: stainless steel overlays substrate chamfering one side, between tiling soldering flux, is placed on pressure platform, and substrate and stainless steel are encircled to all seal weldings; (4) vacuumize: by the hole, right angle on substrate, vacuumize, then hole, shutoff right angle, forms preposition base; (5) close base soldering and sealing: two front base surface stainless steels are involutory, the agent of middle tiling high-temperature adhesion resistant, then at the demarcation strip of the girths such as two corrosion resistant plate surroundings spot welding, then the gap between two chamfering grooves and demarcation strip implements submerged arc soldering and sealing, forms composite billet; (6) boring: symmetry drills through several air-vents on soldering and sealing circle and demarcation strip; (7) hot rolling: composite billet is heated to 1000 ℃~1300 ℃, enters hot mill rolling moulding; (8) trimming finishing separation obtains finished product.The problem existing in the method is: brill hole, right angle technique is more complicated; Front base is vacuumized to the vacuum equipment that needs precision higher; Exhausting and preposition base being implemented to soldering and sealing after vacuum is a more difficult process, requires preposition base cavity to reach higher vacuum and in follow-up production work, keeps this higher vacuum until rolling process always.Therefore this process cycle is long, production process is complicated, and technical difficulty is large.
Along with the continuous increase of society need and the development of production, the demand of stainless steel clad plate is also constantly increased, therefore, improving process means, the technology difficulty that reduces to manufacture stainless steel clad plate of producing at present stainless steel clad plate, reducing production costs, improve stainless steel clad plate output is problem demanding prompt solution in industry.
Summary of the invention
Technical problem to be solved by this invention is for existing vacuum hot rolling composite algorithm, to prepare the problem of the technical existence of stainless steel clad plate, provides that a kind of operation is easy, the cycle is shorter, the manufacture method of the stainless steel clad plate of the more high and low cost of efficiency.
The technical scheme solving the problems of the technologies described above is:
A manufacture method for stainless steel clad plate, it carries out according to following steps:
A. blank is prepared: choose the roughly the same parent metal of length and width size and stainless steel double layer, to be composite the processing ring chamfering groove to parent metal and stainless steel double layer, use the method for milling, plane or mill remove on to be composite of parent metal and stainless steel double layer oxide layer, successively, with to be composite of absolute alcohol and acetone cleaning parent metal and stainless steel double layer, the cool breeze by temperature lower than 30 ℃ dries up;
B. preposition base welding: by the parent metal drying up after cleaning and to be composite relative being stacked together of stainless steel double layer, then will encircle all seal weldings along groove;
C. ply rolling composite billet preparation: the surface stainless steel of two preposition bases is stacked relatively, and brushing interleaving agent between two-layer, adopts the adjacent stainless steel layer head full weld of stainless steel electrode to composite billet, dual-side spot welding;
D. heating and rolling: ply rolling composite billet is put into heating furnace and add thermal control according to the production heating cycle of plied timber; Ply rolling composite billet after heating is rolled to the start rolling temperature of rolling, finishing temperature and roll rear process for cooling and be rolled according to the production technology of plied timber, mill speed 0.5 ~ 3m/s, total reduction >=50%.
