Description
The invention belongs to metal material and coat manufacturing process, particularly, the present invention relates to metal material method for coating and coating unit thereof, as the method for coating and the coating unit thereof of zinc band anode.
The metallic cover material has for example copper covered steel wire, aluminum-clad steel wire, zinc steel clad wire, sheath steel wire, magnesium steel clad wire, zinc alclad line, and that has realized at present large-scale industrial production has copper covered steel wire, an aluminum-clad steel wire.The production method of copper covered steel wire has mechanical coating, galvanoplastic, molten copper infusion process, and aluminum-clad steel wire is only produced with continuously extruded coating method, and the zinc steel clad wire is produced with dip coating and continuously extruded coating method.The equipment that machinery coats is simpler, easy to operate, is easy to control, non-environmental-pollution, but the finishing disposal is bigger, and the copper strips utilization rate is lower, and the combination interface that is obtained is a mechanical bond, and its performance is very different than metallurgical binding; The equipment of galvanoplastic is not too complicated, operate also more easy to controlly, and utilization rate of raw materials is higher, but its efficient is low, and thickness of coating is limited, a little less than the combination of interface, environment is had pollution; The productivity ratio of molten copper infusion process is higher, the big several magnitude of the comparable additive method of thickness of coating, and non-environmental-pollution, but its equipment is complicated, the difficult control of operation; The characteristics of energy-conservation, short flow process that continuously extruded coating method has, the flexible process technology of material forming, realize that in forming process material is compound, but, this method investment is big, operation requires high, be difficult to fusing point height, metal that intensity is big are produced, to the profile shapes of super large-scale, cladding wires can not be produced.Disclose a kind of continuous extruding technology of coated wire among the Chinese patent application CN85100076A, two of this technology utilizations roll wheel lead and clad metal lines are sent into extrusion die simultaneously, once are squeezed into coated wire.A kind of iron core plastic covered wire process units is disclosed among the CN2070026U, this device be draw good iron wire material through and plastic extruder compound mould a layer coating machine, from the hollow tubular plastics materials that forms by plastic mould, pass through, and make the plastics materials of fusion be coated on the iron wire material equably through mould to show.CN1087297A discloses a kind of method and apparatus that adopts the continuously extruded device of two-wheeled to make composite metal wire, this device adopts the continuously extruded device of two-wheeled, be provided with and be used for passage and the clad material input port that coats the chamber communication are coated the chamber and be used for clad material is expressed to the metal core wire that is used to make composite metal wire.Said method or device all exist equipment complexity, not easy-operating defective.And zinc anode generally is applied to the cathodic protection of the pipeline in soil, seawater, the fresh water, particularly is used for protecting the pipeline in the difficult circumstances, as rock, massif, molten ice formation, tundra or the like.Along with the development of society, the demand of zinc anode is increasing, and people press for a kind of method and apparatus of producing the high-quality zinc anode.
The method that the purpose of this invention is to provide a kind of production metallic cover material.
Another object of the present invention has provided a kind of device of production metallic cover material.
Product outflow direction is the extruding force direction in the conventional extruding, because the influence of extrusion axis, extruding pad and extruded bars, the heart yearn that is coated can not keep rectilinear direction with product, causes guaranteeing that heart yearn is coated and guarantee product needed length continuously.The present invention adopts conventional extruder, design mould with Rational structure and parameter, product flows out direction and pushes different with routine, angled with the direction of extrusion, be generally the 60-120 degree, preferred an angle of 90 degrees, make heart yearn and product flow out direction and keep straight line, guaranteed the continuity of producing, endless that product length reaches can satisfy any requirement.
Device of the present invention mainly comprises extruder, cleaning device and heart yearn heater three parts, further specifies method and apparatus of the present invention below in conjunction with accompanying drawing.
Description of drawings
Accompanying drawing I is the sectional view of production clad material device of the present invention, wherein, the 1st, extrusion axis, the 2nd, manipulator, the 3rd, extruding pad, the 4th, cover in the work, the 5th, the recipient overcoat, the 6th, clad material, the 7th, cleaning device, the 8th, heater, the 9th, heart yearn, the 10th, the location internal mold, the 11st, extrusion die, the 12nd, coat good product.
In apparatus of the present invention, extruder can adopt routine to decide extruder, as 800T copper-aluminium extruder; Cleaning device adopts ultrasonic wave to clean hot-air seasoning; The heart yearn heater adopts induction heating equipment.
Heart yearn among the present invention can be steel wire, aluminum steel, copper cash and composite, is shaped as circular or irregularly shaped.For reach with clad material in conjunction with firm effect, heart yearn must at first clean the surface by preliminary treatment before coating, removes surface impurity and greasy dirt; Next is that heart yearn is heated, and makes temperature reach 200-250 ℃.
Clad material among the present invention can be non-ferrous metal or its alloys such as aluminium, copper, magnesium, zinc, at first in auxiliary smelting equipment, be smelted into clad material bar-shaped, enter firing equipment again and be heated to extrusion temperature, add in the recipient work of extruder by manipulator 2 and extrusion axis 1 then and push coating in the cover 4.Clad material is selected different heating (extruding) temperature with the difference of metal or alloy, is 400-500 ℃ as heating (extruding) temperature of aluminium and aluminium alloy, and the heating-up temperature of copper (extruding) is 800-900 ℃, and the heating of zinc (extruding) temperature is 200-300 ℃.
Product of the present invention flows out direction and pushes different with routine, the product outflow direction and the direction of extrusion are angled, and heart yearn and product flow out direction maintenance straight line, have guaranteed the continuity of producing like this, product length can reach endless, can satisfy the random length requirement.
The present invention is by changing the outlet shape of location internal mold 10, can obtain the product of different shape, shape of product can be circular, square, rhombus, also can be other shapes, according to different application scenarios, different customer requirement and deciding just changes the structure and the shape of mould, and all the other devices need not done any change.The product size size also can be decided as requested, also just mould is changed.
The method of production metallic cover material of the present invention is to be smelted into clad material bar-shaped in auxiliary smelting equipment earlier, in auxiliary firing equipment, be heated to extrusion temperature again, add in the recipient work of extruder by manipulator 2 and extrusion axis 1 then and push coating in the cover 4, evenly coat in location internal mold 10 and extrusion die 11 at clad material under the effect of extrusion axis 16 and the pretreated heart yearn of process, obtain compound product, product is after batch packing after the cooling.
