The manufacturing method is characterized in that a laser-melting forming technology is adopted to form an anti-wear lining capable of resisting zinc liquid corrosion on the surface of inner holes of a basic material, and comprises the following steps: (1) removing the oil stains and oxide scales from the surface of the basic material of a composite lining; (2) carrying out flaw detection to ensure that the basic material does not have any crack or pore defection; (3) carrying out laser melting and forming with a special melting and coating alloy material; (4) carrying out inspection to ensure that no crack, pore, or impurity exists. A novel manufacturing method is provided for producing lining for galvanizing and solves the problems that in the prior art the technology is complicated, the binding force is lower, the tissue is rough and big, the thermal input amount is large, and the requirements on equipment are high.
Description
Technical field
The present invention relates to a kind of manufacture method of composite bush, particularly relate to a kind of manufacture method adopting the pot galvanize lining of laser melting and coating process.
Background technology
At present due to the development of automotive industry, more and more higher to the specification of quality of galvanized sheet, but due to the corrosive nature of galvanizing zinc and higher strip speed in the production process of galvanized sheet, make the endoporus erosion corrosion of zinc pot bottom bracket axle to lining very serious, usual use will be rolled off the production line for about 15 days, and lining hole size diametrically can increase more than 6mm.And in order to reach this life cycle, the manufacture of initial lining uses the corrosion-resistant and good cobalt base alloy of abrasion resistance properties to carry out monoblock casting usually, this makes the manufacturing cost of lining very high, causes waste to resource simultaneously, also to environment.
In order to reduce costs, protection of the environment, has a lot of pot galvanize lining to adopt the method manufacture of bimetal compound at present, mainly contains cast setting, the methods such as built-up welding, but all there is respective deficiency.Cast setting method is the matrix endoporus rolled alloy pipe of anticorrosive anti-wear being embedded in liquid zinc corrosion resistant, and adopt the mode of machinery to be fixed on matrix inwall, the lining complex process that this method manufactures, and be non-metallurgical binding, poor bonding strength, easily because bi-material coefficient of expansion difference causes alloy layer to be separated; Adopt the mode such as argon arc or plasma directly direct built-up welding one deck anticorrosion antiwear layer on the inwall of the matrix of liquid zinc corrosion resistant Deng welding method, although this method simplifies technique, bonding strength is high, but due to heat input, greatly easily to cause alloy layer to organize thick, heat affected zone is large, be out of shape the shortcomings such as large, and when matrix diameter of bore is less, have certain restriction to surfacing equipment.
Therefore, choose a kind of suitable pot galvanize lining manufacture method and, be that current zinc-plated industry needs problem demanding prompt solution.
Summary of the invention
The object of the invention is to the problems referred to above solving prior art existence, by a large amount of tests, propose a kind of manufacture method of new pot galvanize lining.The present invention adopts on the stainless steel base of the liquid zinc corrosion resistant added in pre-first chance more corrosion-resistant as thermal source cladding with laser, wear-resistant alloy functional layer, the powdered alloy of the material selection special configuration of cladding or silk material, the present invention adopts the pot galvanize lining of this many metal composite of the method manufacture of laser melting coating to have the performance of excellent wear-resistant and liquid zinc corrosion resistant.The service requirements of galvanization production line can be met completely, effectively can also reduce the manufacturing cost of lining, simplify the complex process in lining manufacturing processed, avoid the phenomenon that anticorrosion antiwear alloy layer is separated; Simultaneously owing to adopting high energy density laser Shu Zuowei heat point source, heat input is little, can avoid alloy layer organize thick, heat affected zone is wide and easily cause the problems such as thermal distortion; And can adopt the mode such as optical fiber or speculum that laser source is imported endoporus, carry out the laser melting coating of small-bore, not by the restriction of equipment size.
The technical scheme that the present invention provides is: a kind of manufacture method of pot galvanize lining, be characterized on a kind of tubular matrix endoporus of liquid zinc corrosion resistant, adopt one or more layers wear-resistant and alloy layer functional layer that is liquid zinc corrosion resistant of the method cladding of laser cladding forming, finally mechanical workout is carried out to functional layer surface, make it reach working conditions and requirement, its processing step is as follows.
(1) dirt such as greasy dirt, oxide skin of the substrate surface of composite bush is cleared up.
(2) detect a flaw, comprise penetrant inspection, x-ray detection, UT (Ultrasonic Testing), fluorescent inspection, do not allowed crackle, gas hole defect.
(3) laser cladding forming.
Clamping is being just on laser process machine turning axle for the tubular substrate pre-first chance added, then LASER Light Source to be imported in tubular substrate endoporus and to adjust laser focal, the powder sending quantity of special cladding alloy material or silk feeding quantity are adjusted simultaneously, open dedusting and device for inhaling powdery substances, then carry out laser melting coating.
Wherein the processing parameter of cladding process is: power: 1800 ~ 4000W, focal length: 20 ~ 150mm, spot diameter: 3 ~ 10mm, sweep velocity: 10 ~ 30mm/s, fore-put powder thickness 1.5 ~ 3.0mm.Special cladding powdered alloy composition is (mass percent): C:1-2%, Cr:20-30%, W:10-15%, Mo:15-20%, Ni:5-10%, Fe:1-2%, Mn:0.2-1%, Si:1-2%, B:1-2%, Co: surplus.
(4) check, comprise dimensional inspection, nondestructiving inspecting test, require defects such as not allowed crackle, pore, be mingled with.
(5) mechanical workout is carried out on request.
Compared with prior art, the invention has the beneficial effects as follows.
1. for the manufacture of pot galvanize lining provides a kind of brand-new manufacture method.
2. adopt the duplex metal composite bush of laser cladding forming manufacture technics to solve traditional method and manufacture composite bush complex process, bonding strength is low, organizes thick, and heat input is large, requires the problems such as high to production technology and eqUipment.
