Abstract
The invention provides a composite material for a chain and a manufacturing method. The method comprises the following steps: A, positioning chain parts manufactured from low-carbon steel or low-carbon alloy steel into a preheated heating furnace, such as a hinge pin, a sleeve, a ball, an inner chain plate and an outer chain plate, or heating through a high frequency electromagnetic coil to enable the surface temperature to be more than a melting point quickly; B, quickly heating the surface temperature of the parts to reach the melting point by preheating or heating through the high-frequency electromagnetic coil, namely, breaking the original atomic arrangement structure on the part surfaces through temperature raise so as to change the long-range ordered structure into a short-range disordered structure; C, quickly moving out the parts from the heating furnace, and quickly cooling through water or other cooling liquid, so as to obtain a composite material that the inner part remains the original crystalline state and the surface is provided with a layer of amorphous state structure. With the adoption of the method, other mechanical properties and mechanical properties of the material are ensured, and meanwhile, the resistance to oxidation of a chain component is improved, the service life of the chain component is prolonged, and the wearable performance of the chain component is improved.
Description
Technical field:
The present invention relates to chain production technical field, more specifically to the bearing pin of chain, ball, sleeve, inner plate and pin link plate manufacture method.
Background technology:
Existing manufacture of cement industry transporting chain plate used is when carrying cement material; the material particulate hard due to some enters between the bearing pin of chain and sleeve; these hard material particulates can cause bearing pin, sleeve, ball and produce between inner plate and pin link plate and wear and tear more by force; and bearing pin, sleeve, ball, inner plate and pin link plate be not through quench treatment; its surface hardness is limited; in half a year in one-year age, easily cause chain wear serious, even produce chain breakage phenomenon.
Summary of the invention:
Object of the present invention is exactly the deficiency for prior art, and provides a kind of chain matrix material and manufacture method,
It is when ensureing other mechanics of chain and mechanical property, the oxidation-resistance adding chain members, the work-ing life extending chain members and add the wear resisting property of chain members.
Technology solution of the present invention is as follows:
A kind of chain matrix material and manufacture method, A, chain part bearing pin, sleeve, ball, inner plate and pin link plate by with soft steel or low-carbon alloy steel making are placed in the pot arch of heating in advance, or adopt in high-frequency electromagnetic coil and heat, make its temperature reach more than fusing point fast;
B, part to be taken out rapidly from pot arch, be placed in water or other cooling fluid and cool rapidly, make its surface form the material of amorphous structure, the object of cooling is fast: have little time to form crystalline structure with regard under rapid solidification at the atom of material surface, form amorphous structure;
C, make part form inside to be original crystalline structure and surface is the matrix material of one deck amorphous structure;
Temperature in D, pot arch is warmed to more than the fusing point of material in advance, and heats to part rapidly, makes its surface reach fusing point, make its surface form the distribution that molten state had both formed short distance disordered structure, and the microtexture of inside parts does not change.
Beneficial effect of the present invention is:
It is when ensureing other mechanics of chain and mechanical property, the oxidation-resistance adding chain members, the work-ing life extending chain members and add the wear resisting property of chain members.
Embodiment:
Embodiment 1: a kind of chain matrix material and manufacture method, A, by the chain part bearing pin of 45 steel makings, sleeve, ball, inner plate and pin link plate be placed in be warmed to 1550 DEG C in advance pot arch in, its surface temperature is made to reach 1525 DEG C fast (preferably not more than fusing point 50 DEG C, exceed that fusing point is too high can be become liquid phase on its surface and flow, change the shape of part), be incubated 30 seconds, the material that the material of such piece surface defines Rong Rong state both piece surface thickness 0.2mm becomes short distance disordered structure by long range ordered structure, and be deep into material or crystalline structure in 0.3mm,
B, to be taken out rapidly from pot arch by part after 30 seconds, be placed in water or other cooling fluid, make the atom of material surface have little time to form crystalline structure and get off with regard to rapid solidification, upper layer forms amorphous structure;
C, like this part material just define inside and are original crystalline structure and amorphous structure matrix material that surface has one deck 0.8mm thick;
Principle of work: the present invention adopts high-temperature heater to heat, when chain members inside is heated up not high, material surface is formed and the distinguishing short distance disordered structure in inside, then cooling is that this short distance disordered structure solidifies fast, formation is inner has other matrix material with surface; Because non-crystalline state has the tiny flaw of dense distribution, make when oxidized, surface forms tight zone and prevents further oxidation; Such matrix material is improve chain members life-span, reliability, the rustless properties of materials such as tensile strength, yield strength, elongation, relative reduction in area that simultaneously ensure that chain.
