Description
Technical field
The present invention relates to a kind of metal Roof system manufacture field, the preparation method of seat fixed by a kind of aluminium alloy.
Background technology
In recent years, the architectural design concept of domestic construction circle a large amount of Introduced From Abroad advanced person and method system, wherein building decoration body of wall and Roof Design aspect, mainly include using door and window, curtain wall and ceiling system (industry refers to metal Roof system), and the composition at these building decoration positions, it be unable to do without the structural member of all kinds of difference in functionalitys, and be the key realizing whole design system.
Sheet metal is widely used as the roofing of a kind of one's best quality, the most especially Europe.Metal Roof material, mainly has the materials such as aluminium alloy plate (aluminium sheet), titanium zine plate, corrosion resistant plate；In conjunction with the different system such as stile occlusion, high stile, Bei Mu, same its moulding not being restricted to one pattern of displaying and flexile change, make whole building industry present the full-frills brand-new world.
Aluminium alloy is fixed seat and is born huge pulling force and stress effect in whole metal Roof system, therefore, seat product fixed by aluminium alloy must have the combination properties such as high intensity, high tenacity, high bending resistance and highly anti-fatigue, just can ensure that the security of metal Roof and the realization of function.But, during some aluminum alloy plate materials roofworks at home uses, the accidents such as fixing seat easy fracture deformation, poor corrosion resistance cause integral roofing lifetime of system short often occur.So, how can improve aluminium alloy and fix the combination property of seat, the problem paid special attention in always becoming industry.
Summary of the invention
The invention aims to overcome the deficiencies in the prior art, it is provided that a kind of manufacture craft is reasonable, and the preparation method of seat fixed by the aluminium alloy that product high comprehensive performance, yield rate and efficiency are high.
The present invention is achieved in that
The preparation method of seat fixed by a kind of aluminium alloy, it is characterised in that including that founding refines, homogenizes, extrudes, machines, is heat-treated, surface processes, dries and pack warehouse-in, step process is as follows:
(1) founding refining: by after the fusing of aluminium ingot that aluminium content is more than 99.75% in smelting furnace, add the intermediate alloy of Mg and Si, through degasification, removes the gred, refines and standing etc. processes, then aluminum alloy melt imports tubular type filtration system, and is passed through Cl, N online2Mixed gas processes the H in alloy and low-melting impurities further, and finally casting obtains aluminium bar；
(2) homogenization: loaded by aluminium bar in heating furnace, carries out strength in being transferred to cool down stove and cool down at temperature is 550-580 DEG C after being incubated 4-6h；
(3) extruding: by aluminium bar after power frequency induction furnace heats, is cut into, by hot shears, the stub being suitable for extruding and carries out extruded, obtain aluminum alloy base material；
(4) machining: aluminum alloy base material is carried out successively finishing mandrel, edging, punching and the operation at the bottom of mill, obtains aluminium alloy and fix seat；
(5) it is heat-treated: aluminium alloy is fixed seat and puts in heating furnace and quench, hardening heat is 540-550 DEG C, time is 35-45min, aluminium alloy is fixed and is carried out water-cooled after seat is come out of the stove immediately, then artificial aging is carried out, aging temp is: 180-200 DEG C of time is 4-6h, and timeliness is come out of the stove after completing air cooling；
(6) surface processes: the aluminium alloy through Overheating Treatment is fixed seat carry out successively washing, degreasing, washing, alkali cleaning, the operation of washing；
(7) dry: the aluminium alloy after surface processes is fixed seat and is placed on ventilation and dries；
(8) packaging warehouse-in: aluminium alloy is fixed seat product inspection, qualified product packaging warehouse-in.
Above-described degreasing is aluminium alloy to be fixed seat put into and carry out ungrease treatment in degreaser, and degreaser is weight content 10%-15% acidic aqueous solution, and degreaser includes sulfuric acid, ferric sulfate, hydrogen peroxide and surfactant；Sulfuric acid, ferric sulfate, hydrogen peroxide, the percentage by weight of surfactant are 60-75:10-20:8-12:5-10.
Above-described alkali cleaning is that aluminium alloy is fixed seat and put in alkali lye immersion 20-30s, alkali lye be weight content be NaOH or the potassium hydroxide of 10-18%.
The prominent substantive distinguishing features of the present invention with significantly progress is:
Aluminium alloy the most of the present invention is fixed seat product and is had the combination properties such as high intensity, high tenacity, high bending resistance and highly anti-fatigue, can effectively prevent fixing seat piece from rupturing, it is to avoid security incident occurs.
Aluminium alloy the most of the present invention is fixed seat and is only limited roof boarding in plate width direction and the movement of above-below direction, it is not limiting as the roof boarding movement along plate length direction, therefore roof boarding can be fixed at aluminium alloy when temperature change and freely stretch on seat, temperature stress will not be produced, effectively solve the temperature deformation problem that other templates are difficult to overcome, it is ensured that the safety and reliability of roofing performance.
Seat fixed by aluminium alloy the most of the present invention can effectively prevent electrochemical corrosion, make aluminium alloy fix seat and mate the requirement in service life meeting roof board material completely, avoid fixing seat because of aluminium alloy to scrap in advance because of effects such as electrochemical corrosion, affect the whole service life of whole Roof system.
