Description
Technical field
The invention belongs to composite board technical field, particularly relate to a kind of casting double-sided composite plate/compound casting and life thereof
Product method.
Background technology
Double-sided composite plate is with carbon steel, steel alloy as base material in the middle of one, two-sided other material compound cover material (face
Material), base material with cover composite plate, the foundry goods that material is combined into one with certain connected mode, have concurrently auxiliary material material characteristic property and
Carbon steel, the intensity of steel alloy, be high, the economical and practical new energy-saving material of a kind of cost performance, have the most wide market
With huge economic worth.
For convenience of description, as a example by composite stainless steel plate, to stainless steel clad plate the most both at home and abroad
And production method is described below.
In short, current stainless steel clad plate has the three class modes of production: solid-solid phase is compound, liquid-liquid phase is compound, liquid-solid
It is combined mutually.
Solid-solid phase is combined: mainly include that Explosion composite, welding-Rolling compund, Direct Rolling are combined.Mixed economy type,
Practicality, base material and the reason such as bond strength covering material, mainly Explosion composite method and the welding of current large-scale industrial application
Roll-bonding method.Explosion composite method base material with cover that material bond strength is good, metallurgical interface combination rate high, but production cost is high, by oneself
So Meteorological Elements in China impact is big, cannot carry out, as overcast and rainy, operation of exploding, it is difficult to realize large-scale production, and explosion time
Produce serious noise, dust pollution, the most have become increasingly limited.Welding-roll-bonding method: base material is the lowest
The composite surface of carbon steel sheet is polished the dirts such as rust cleaning, removing oxide layer.Rustless steel composite surface is polished rust cleaning removing oxygen
Change film.During for preventing rolling, carbon steel to stainless steel cementation and stops the compound interface cleared up to reoxidize, have at base material or
Cover and on the interface that material is cleared up, coat layer of metal nickel, then base material is overlapped with covering material, superposed surfaces surrounding soldering and sealing, stay during soldering and sealing
One aspirating hole, from aspirating hole, vacuumizing makes combination interface keep high vacuum state, just completes weldering after closing aspirating hole
Connect the making of composite plate blanks.After composite plate completes rolling, need to cut away the soldering and sealing layer of surrounding.Before it should be noted that rolling
There is not any physics, chemistry and metallurgical binding form in composite plate blanks interface, only during slab rolling, at high temperature and
Under the effect of powerful roll-force, the metallurgical binding that compound interface is limited could be realized, because of its interface cohesion degree by rolling temperature,
Numerous links such as drafts, roll-force, compound interface cleannes, compound interface vacuum (or protective capability of noble gas)
Impact, the metallurgical binding determining base material with covering material and be difficult to 100%, user use the method produce composite plate bending,
During distortion, it may appear that cover the phenomenon that material departs from base material, hit the use confidence of consumer.The method technique is loaded down with trivial details,
Manufacturing cost is high, it is difficult to realize large-scale industrial production, it is not easy to upper yield, is known as the welding-rolling of largest domestic at present not
Rust steel composite board enterprise, annual capacity only 30,000 tons.
Liquid-liquid phase is combined: being again continuous casting electromagnetic composite algorithm, its ultimate principle is by mean of being arranged on two below crystallizer
Individual levels electromagnetic field, utilizes Lorentz force each to retrain the molten steel of unlike material, completes answering of different materials in casting process
Close, have pollution-free, compound strength of materials is high, be suitable for the feature of large-scale production, but at present process equipment all imperfections, be in
The stage of further investigation demonstration further.
Liquid and solid bonding me thod: include reverse solidification method, casting and roll process etc..Reverse solidification method is a kind of immersion plating composite algorithm, by one
Determining the solid base material master tape of thickness, continue through and melted cover in material molten steel, molten steel generates certain thickness in master tape surface solidification
Cover material.The method has efficiency height, energy consumption is low, quality good, production procedure is short, be capable of quantity-produced feature, but behaviour
Make difficulty big, current process equipment all imperfections, it is in the stage of further investigation demonstration further.Casting and roll process is will partly to solidify shape
The metal of state and solid metallic are simultaneously fed into mill milling, can realize the compound of high-melting-point and low-melting-point metal, combined strength bination is high,
Production efficiency is high, low cost, but the equal imperfection of process technology equipment at present, still it is in the stage of further investigation demonstration.
In sum, current rustless steel complex method and technology, except still at the electromagnetic continuous casting method, anti-in research and probe stage
Outside freezing method, practical application in industry is Explosion composite method and welding-roll-bonding method.Explosion composite method coating is tied with basic unit
Conjunction quality is good, but effect on environment is big, and cost is high, yields poorly, base material is with to cover material deflection big, it is difficult to form large-scale production.Weldering
Connect-roll-bonding method is current most common a kind of production method, but is difficult to large-scale industrial production, and cladding plate with
Substrate interface bond strength is poor, unstable product quality, causes consumer to use the confidence of welding-Rolling compund corrosion resistant plate
Deficiency, have impact on the popularization and application of welding-rolling stainless steel clad plate.
Summary of the invention
It is an object of the invention to, overcome the deficiencies in the prior art, it is provided that a kind of casting double-sided composite plate/compound casting
And production method.Including covering material and base material, covering material and can arrange in pairs or groups with arbitrary proportion with base material, base material waters with the form of molten steel
Cast onto two pieces and cover in the middle of material, form the metallurgical binding covering material and substrate interface 100%, and do not have and cover material by high-temperature molten steel
Melting loss.
For solving above-mentioned technical problem, the technical scheme is that a kind of life casting double-sided composite plate/compound casting
Product method, described double-sided composite plate/compound casting includes covering material and covering the base material between material, base material two of both sides external
Melted, then it is molded into two and covers in the middle of material.The described material that covers is rustless steel, titanium plate or various alloying component sheet material, steel-casting, cast iron
Part；Described base material is carbon steel, steel alloy, ironcasting.
Before casting, coating Ni-based coating at the medial surface covering material, described medial surface is the combination interface covering material with base material,
The painting method of described Ni-based coating is plasma spraying, electric arc spraying or flame-spraying, the Ni-based painting of this painting method described
The constituent of layer is by weight: nickel 50-100, tungsten 10-35, cobalt 10-25；Spray the thickness of Ni-based mixed coating: 5-
200um。
The painting method of described Ni-based coating is brushing or spray construction method, the Ni-based coating of this painting method described
