Background technology
The material of annular chains, 80 grades of general desired strength rank and the above, major diameter chain use more
23MnNiMoCr54 steel makes, and 20Mn2 or 25MnV are then following with minor diameter chain mainly for the production of 80 grades of intensity rank.
Circle chain of mine, it is one kind of annular chains, is mainly used in colliery, is important on coal mining equipment scrapper conveyor
Consumable product, its service life directly determine the production efficiency of scrapper conveyor.Circle chain of mine uses relative to other round-link chains
Environment is more severe, and first, for scrapper conveyor in initial start stage, circle chain of mine bears huge tensile stress, in theory its moment
Pulling force can reach the 60% of its rupture pull force, if the situation that wearing occurs in chain or the performance such as fatigue reduces, it is likely that can wink
Between break and quality accident occur, injure equipment and personnel.Secondly, chain directly rubs with coal and contacts baseplate, moment
Scouring is damaged.A piece up-to-standard chain, abrasion are the main reason for causing chain to scrap, and the deciding factor worn depends on
In the case hardness of chain, and the case hardness of chain is mainly determined by material quality adjustment condition, meanwhile, circle chain of mine is using
When, also it is immersed in the aqueous solution containing acid or alkali, acid or alkali also accelerate chain wear, so as to, it is also possible to cause fatigue rupture
Deng, therefore, circle chain of mine relative tensile, it is wear-resisting, it is corrosion resistant require it is higher.
But conventionally, as annular chains preparation technology is unreasonable, annular chains are caused to be deposited using process

Embodiment
With reference to specific embodiment, specific embodiments of the present invention is described in detail.
As shown in figure 1, the invention discloses a kind of wear-resisting erosion resistance annular chains, by multiple improvement coating in chain surface structure
Into, the chain includes matrix 1, in the outside of described matrix 1, is disposed with Al-Fe layers 2 and rare earth sial 3 from inside to outside,
The rare earth sial 2 is coated on the outside of described matrix 1, and the Al-Fe layers 3 are coated on the outside of rare earth sial 2.It is preferred that
Ground, the rare earth silicon aluminum layer thickness are 100-130 μm, and the Al-Fe thickness degree is 10-40 μm.Further, the Al-Fe
Layer includes FeAl layers, Fe3Al layers and Fe5Al layers.
A kind of preparation method of above-mentioned wear-resisting erosion resistance annular chains, comprises the following steps：
1) annular chains of steel matrix support are chosen, using the process of hot-dip or thermal spray in the annular chains
Surface plug-in rare earth sial and Al-Fe layers successively；
2) annular chains that step 1) obtains are placed at 700-900 DEG C and carry out thermal diffusion, diffusion time 5-
150min。
Now, about 30 μm of about 120 μm of rare earth silicon aluminium coat thickness and Al-Fe thickness degree.
Then, 780 DEG C or so thermal diffusions of annulus chain warp, make rare earth silicon aluminium coat expand successively in chain surface ecto-entad
Dissipate, gradually form ring-type cladding pure rare earth sial, FeAl layers, Fe3Al layers and Fe5Al layers, as shown in Figure 2,3：Rare earth aluminium
Microscopic structure and hardness figure are permeated, has just produced cementation of rare-earth sial annular chains.
Wherein, pure rare earth sial, FeAl layers and Fe3Al layers have different degrees of antisepsis, and FeAl is relatively hard
Degree is high, and wear-resistant, its Weishi hardness may be up to Hv800~Hv1100, and then hardness is relatively low for Fe5Al layers, and ductility is good, because
This：The cementation of rare-earth aluminium annular chains are in practical application, for example：
It is directed to the annular chains for being mainly used in anti-corrosion or marine environment --- fishing chain, due to the requirement of its rupture strength
It is not high, easily using low temperature osmotic, retain the rare earth sial of outside covering as far as possible, make anti-corrosive properties good, and surface is firm
It is durable.For fishing chain, counterweight effect is normally only played, does not require to possess very high intensity rank, does not need quenched place typically
Reason.Generally we are made using economic 20Mn2 or 25MnV materials.
When we produce be mainly used in it is wear-resisting based on round-link chain when, then increase FeAL thickness as far as possible, it is high hard to carry it
Matter layer antiwear property, the pure rare earth sial of outside can be ignored, to improve osmotic efficiency, using 850 DEG C of thermal expansions in 2 hours
Dissipate, AL layers evaporate in heat leak.If the annular chains do not have intensity requirement, can also use do not quench, temper.
But for producing circle chain of mine bar, then require that it had not only had good antiseptic property but also require to have enough resistance to
Performance is ground, also to ensure that round-link chain FeAL layers should not be too thick, and forms uniform crystal growth interface.Because circle chain of mine
Bar is run in the aqueous solution containing acid or alkali, and based on wear out failure, its surface in stretching repeatedly, it is impossible to which generation is opened
Split, to ensure its fatigue life.
Below, the one group of diameter phi 26mmX92mm mining annulus of 23MnNiMoCr54,20Mn2 and 25MnV material steel is passed through
The production process of chain, cementation of rare-earth aluminium annular chains and its application is further illustrated：
1st, it is qualified through examining after taking above-mentioned three kinds of unlike materials to carry out annular chains welding respectively, take diameter phi
26mmX92mm 23MnNiMoCr54 materials, each one of 1 meter of 20Mn2 and 25MnV materials long round-link chain, through shot-peening, derust and
After degreasing processing, immerse in 780 DEG C of 2 hot dip rare earth sial stoves 5 minutes.
2nd, take out, make the rare earth aluminium lamination of about 64 μm of uniform hot dip a layer thickness in annular chains surface, now, chain surface is oozed
About reach 35 μm thoroughly, as shown in Figure 4：Rare earth aluminium grain growth figure, then：
3rd, the chain of 20Mn2 and 25MnV materials is taken out, using 700 DEG C of thermal diffusions in 2 hours, the chain is through salt spray test pair
Than：
Steel matrix：There is obvious rust spot within 4 hours；
Hot-dip：Do not occur rust spot yet within 1200 hours；
Thermal diffusion：356 hours still without rust spot.
4th, 23MnNiMoCr54 materials chain is incubated, further rare earth aluminium infiltration, according to chain requirement of shelter, passes through heat
Time of penetration reaches default alloy layer thickness, and will progressively be warmed to 980 DEG C or so phase transition temperatures, then rapidly cold by pond
But quench, then lonneal again.
5th, through examining, rare earth aluminium is hard on chain metal surface, formation aluminium-iron-silicon-rare earth alloy layer, 100 μm of surfaces of thickness
Degree reaches Hv900 and has fairly good corrosion resistance.Chain strength after quenched, reach 80 grades through rupture test, meet
Other performance indications requirement of GB/T12718-2009 standards.
Finally it should be noted that：The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the invention,
Although the present invention is described in detail with reference to the foregoing embodiments, for those skilled in the art, it still may be used
To be modified to the technical scheme described in foregoing embodiments, or equivalent substitution is carried out to which part technical characteristic.
Within the spirit and principles of the invention, any modification, equivalent substitution and improvements made etc., it should be included in the present invention's
Within protection domain.
