Or electron-beam melting technology (EBM, EBSFF) (LENS).
Steel substrate in this crystallizer parts acts primarily as structure supporting role, the back board structure of corresponding former assembled crystallizer
Function；Copper base has good heat conductivility because of cuprio material, and this part primarily serves quick conductive cooling effect, corresponds to
The copper coin structure function of former assembled crystallizer；Work coating is the working lining of crystallizer, and it contacts with molten steel and initial solidification shell,
Primarily serve the effect of wear-and corrosion-resistant high temperature resistance.
This crystallizer parts have significant advantage, due to copper base and steel substrate compared with tradition assembled mold structure
It is that metallurgical binding is connected as a single entity, thus can solve the many difficult problems faced in tradition assembled crystallizer manufacture and application.
In such as tradition assembled crystallizer manufacture, copper coin is bolted with backboard, needs first to process spiral shells up to a hundred at the copper coin back side
Hole, also need to be bumped into rustless steel thread bush because copper coin intensity is low in these screws up to a hundred, adds the biggest to processing and later maintenance
Difficulty；Copper coin back need to process tank, is fitted on backboard by copper coin thus forms cooling water channel, for ensureing copper coin and the back of the body
Fitting tightly of plate, bolts up to a hundred fastening must be consistent and reliable and stable；In addition in order to prevent, copper coin and backplane are bad to be caused
Situation about leaking, it is necessary to seal structure with the design of backboard faying face outmost turns at copper coin, and in use because of applying working condition
Severe sealing ring is easy to lose efficacy, and need to often change and cause frequently dismounting, the most in use because sealing mistake
Imitate and leak, cause work safety accident.This integral type crystallizer modular construction fills without the screw thread that tradition crystallizer is complicated
Distribution structure, simple in construction, and without sealing structure, it is to avoid traditional assembled crystallizer leaks because of seal failure during using
Great difficult problem, and simplify manufacturing process.
Cooling water channel form can refer to tradition assembled crystallizer cooling structure, but with tradition assembled mold structure phase
Ratio has obvious change.Tradition assembled crystallizer copper coin be fastened by bolts with backboard in together with at faying face formed
Cooling water channel, because of the existence of thread bush on copper coin, the distribution on copper coin of the former cooling water channel must avoid thread bush position, from
And thermo parameters method on sustained height when causing whole copper coin surface to work is uneven, the most even can have 10～20 DEG C
The temperature difference, have a strong impact on the cooling effect of crystallizer, and then cause continuous casting billet surface that defect occurs, affect continuous casting billet product matter
Amount.And this integral type crystallizer parts are integrated metallurgical binding because of copper base and steel substrate, therefore connect without bolt, cooling water channel
The most there is not the problem avoiding thread bush position, the distribution of cooling water channel can more appropriate design, thus obtain more uniform
Thermo parameters method.
This method is entirely different with tradition assembled crystallizer manufacture method and route, and tradition assembled crystallizer is by carrying on the back
The copper coin of plate and band work coating is by bolts assemblies in being integrally formed, and its manufacture method is backboard and copper coin to be processed into the most respectively
Respective structure, the processing of its dorsulum mainly includes the plane machining of backboard, hole machined and seal groove processing etc.；Copper coin processing is main
Copper coin plane machining to be included, back side tank and screw processing etc., then in copper coin front preparation work coating and by work painting
Layer machining is to requiring size；After finally disposing sealing strip between copper coin and backboard, bolt fastening is assemblied in and is integrally formed product.
The cooling water channel distributing position of this crystallizer parts can be inside copper base, it is possible at copper base and steel substrate
Faying face, by copper base side or by steel substrate side, it is possible to be the combination of above several situation.Cooling water channel can be increased by metal
Material print manufacture process directly print, this just this integral type crystallizer parts with tradition crystallizer manufacture important difference it
One.Directly printing cooling water channel by increasing material manufacture method thus broken away from the restriction of traditional mechanical processing, cooling water channel can
According to production status demand, the position of arbitrarily devised cooling water channel, shape and distribution, so can obtain than traditional design more
Uniform cooling temperature field and higher cooling capacity, be more suitable for the production application of current efficient high-speed continuous casting line.Additionally,
Owing to this integral type crystallizer parts print acquisition by increasing material, it is not necessary to bolt connects, and the flexibility design of cooling water channel
Can obtain that cooling capacity is higher, Temperature Distribution evenly, thus can be substantially reduced the copper plate thickness of tradition crystallizer, save more
While many copper materials, also help the continuous casting type of band electromagnetic agitation, be conducive to improving the quality of steel products.
This method compare tradition assembled crystallizer manufacture method the easiest, by increase material printed steel substrate,
Copper base, the compound monolithic construction of work coating three part heterogeneous material build, and carry out overall processing the most again, it is to avoid pass
Assembling between the system each parts of assembled crystallizer is complicated, the problem of precision guarantee difficulty.
In sum, the present invention propose integral type crystallizer parts and preparation method overcome tradition crystallizer manufacture and
Problems present in application, if tradition crystallizer is to ensure that copper coin is connected with backboard to process the processing that a large amount of screw causes
Difficulty and easily cause assembling the problem scrapped because the dislocation of copper plate distortion screw in the application；Because the existence of screw needs
The problem that the copper material using big thickness copper coin to cause is wasted in a large number；Because of copper coin and backboard be bolted formation cooling water channel,
Peripheral sealing circle caused the problem of security incident because bad working environments loses efficacy to leak, and had important using value and dissemination.
One of specific embodiment as this method, can use 304 corrosion resistant plates as the steel of integral type crystallizer parts
Substrate, rustless steel thickness of slab 90mm, it is preformed with the partial structurtes such as blasthole road, surface sand-blasting texturing, removes surface scale, put
In printing on bed as printed substrates；Use red copper dusty material to print powder, powder grain as increasing material on corrosion resistant plate surface
Degree 45～65 μm, metal increases material and prints process choice selective laser fusing (SLM) technology, implements according to the two dimension slicing of copper base
Increase material to print, build copper base entity, in copper base, include that cooling water channel, the thickness of copper base entity are 25mm；At this cuprio
The increasing material continuing implementation coating on plate prints, and only need to change increasing material and print powder, select nickel-base alloy Ni30 as work
Coating material, work coating print thickness 1mm；Overall structure clears up powder in cooling water channel after completing, and ties entirety
Structure carries out stress-removal process of annealing；Finally overall structure is carried out machining to requiring size, including the band sand of cooling water channel
Water under high pressure processed, thus form final integral type crystallizer parts product.
Above-described embodiment is intended only as a kind of concrete application of this method, and above description should not be regarded as this method
Limit.
