Description
Technical field
The invention belongs to field of material processing more particularly to a kind of clad steel plate and its production methods.
Background technique
The main method of production nickel-base alloy composite plate has explosion method and rolling at present, for composite pipe aspect, machine
Also comparing for tool composite algorithm application is more.The nickel-base alloy composite plate produced using explosion method, specification are very restricted,
It is difficult to meet user's requirement, due to the operation operation of big ability milling train, the nickel-base alloy composite plate of explosion method preparation is only certain
Special dimension is used, and has had already appeared the trend being eliminated.Mechanical composite algorithm is that nickel-based alloy pipe and pipeline steel tube is direct
It is nested together, has no be fixedly connected between the two, application field is extremely limited.In recent years, more and more scholars are directed to and roll
Preparation method prepares the compound plate technique of nickel-base alloy and is studied.
Highly corrosive oil gas field generallys use corrosion resistant alloy even nickel-base alloy during mining operations and oil-gas transportation
Pipeline.Significant raising is not only caused in terms of economic cost, while great limitation is also received on overall performance.It is general
Lead in anti-corrosion tubing and is used as part against corrosion and only accounts for that one third or so is even lower, and rest part is both used as structural support, if
All using corrosion resistant alloy production, it will cause the significant wastages of resource.No matter from economic aspect or aspect of performance, corrosion resistant alloy
The research and development application of multiple tube becomes one of the effective way to solve the above problems.Welding sandwich rolling process is to prepare bimetallic to answer
Condensation material is most economical, efficient manufacturing method, especially produces the composite plate of big specification, and product size precision is high, raw
It produces that high-efficient and significant change will not occur for chemical component between cladding and parent metal, its performance is influenced smaller.It uses herein
Vacuum electron beam welding assembly+hot rolling technique is prepared for a kind of nickel-base alloy composite plate, and process complexity is low, high production efficiency,
Especially suitable for industrial mass production.
Patent " a kind of heat-resistant wearable clad steel plate and its manufacturing method " (application number: 201310287560.5) discloses one
Kind has excellent heat-resisting and wear-resisting property clad steel plate, and performance is uniform, complete in specifications, has a wide range of application, but its refractory layer contains
There are Cr26-28%, Ni11-15%, wearing layer contains C0.2-0.4%, Cr1.6-1.8%, Mo0.18-0.25%, it may have one
Fixed corrosion resistance, but more far short of what is expected than nickel alloy, and its carbon equivalent is higher is not easy to weld.
" a kind of for producing the production method of steel nickel nickel-base alloy composite blank " (publication number: CN104801562A) is introduced
A kind of preparation method for the composite blank preparing nickel-base alloy composite plate for rolling, wherein the phosphorus content of carbon steel layer exists
0.01-0.10%, high production efficiency, adaptation capacity of equipment is strong, and it is compound steel nickel/nickel-base alloy can be further made by the blank
Plate.But be applicable in carbon steel phosphorus content it is lower, be unable to satisfy at present to intensity increasingly higher demands.
Invent " explosion welding methods of nickel-based alloy composite steel plates " (publication number: CN101559527A) " use explosion method
The nickel-base alloy composite plate of preparation, have it is enough effectively that nickel-base alloy plate and general steel plate is compound, thus guarantee clad steel plate
Under the premise of having the advantages that nickel-base alloy is all, have the intensity of needs, to save the usage amount of expensive metal.But
It is that the composite plate that explosive welding produces forms serious noise pollution to surrounding enviroment in the process, has been gradually backed out the arena of history.
By the above immediate prior art it is found that the production method of clad steel plate has following deficiency at present:
1, it needs to vacuumize after welding or weld under vacuum conditions, production efficiency is low；
2, composite plate substrate strength performance is lower, can not adapt to big intensity requirement；
3, explosion technology generates serious noise pollution, is unfavorable for environmental protection.
Summary of the invention
It is an object of the invention to overcome the above problem and insufficient and provide a kind of simple production process, production efficiency and can
By property height；The production method of the clad steel plate of compound interface excellent in mechanical performance.
The object of the present invention is achieved like this:
A kind of production method of clad steel plate, including Substrate sheet and clad sheet steel milling, stack, preheat, welding, plus
Heat, rolling, cooling carry out milling processing to a surface of clad sheet steel and Substrate sheet respectively, and milling face is stacked relatively
150 DEG C~200 DEG C are preheating to after together, to remove the steam of contact surface, reduce atmospheric density and oxygen content in gap,
The surrounding of contact surface is welded again, stays φ 5~30mm hole at solder up, then with aluminum strip by holes blocking, it can be to prevent
Only contact surface aoxidizes in 660 DEG C or less heating processes.And 660 DEG C or more leads melt, and internal high-pressure gas is excluded, it can be to prevent
Only burst in steel plate bulge and the operation of rolling；This method vacuumizes, greatly without welding in a vacuum chamber without in postwelding
Working efficiency is increased, equipment investment and occupied area are reduced.
Further, milling surface roughness Ra is not more than 10um after clad sheet steel and Substrate sheet milling；Cladding when rolling
Steel plate is under, and upper, slab heating temperature is controlled at 1230 DEG C~1280 DEG C Substrate sheet；Slab start rolling temperature is controlled 1200
DEG C~1250 DEG C；Percentage pass reduction is more than or equal to 25%；It rolls rear and water-spraying control is carried out to the plied timber of downside, open cold temperature
At 900 DEG C~950 DEG C, for cooling velocity in 15 DEG C/s~25 DEG C/s, red temperature is the excellent mechanics of base at 550 DEG C~600 DEG C
The guarantee of performance.
