1 Gukoresha aluminiyumu mu nganda zitwara ibinyabiziga
Kugeza ubu, ibice birenga 12% kugeza kuri 15% by’ibicuruzwa bya aluminiyumu ku isi bikoreshwa n’inganda zitwara ibinyabiziga, hamwe n’ibihugu bimwe byateye imbere birenga 25%. Mu 2002, inganda zose z’iburayi zatwaye toni zisaga miliyoni 1.5 za metero ya aluminiyumu mu mwaka. Toni zigera ku 250.000 zikoreshwa mu gukora umubiri, toni 800.000 za metero zo gukora sisitemu yo kohereza amamodoka, hamwe na toni 428.000 za metero ziyongera mu gukora ibinyabiziga na sisitemu zo guhagarika. Biragaragara ko uruganda rukora amamodoka rwabaye umuguzi munini wibikoresho bya aluminium.
2 Ibisabwa bya tekinike kumpapuro za kashe ya Aluminium
2.1 Gushiraho no gupfa Ibisabwa kumpapuro za Aluminium
Inzira yo gukora aluminiyumu isa niy'impapuro zisanzwe zikonje, hamwe nogushobora kugabanya imyanda hamwe nibisigazwa bya aluminiyumu wongeyeho inzira. Ariko, hariho itandukaniro mubisabwa bipfa ugereranije nimpapuro zikonje.
2.2 Kubika igihe kirekire Amabati ya Aluminium
Nyuma yo gusaza gukomera, imbaraga zumusaruro wimpapuro za aluminiyumu ziriyongera, bikagabanya imikorere yabyo. Mugihe cyo gupfa, tekereza gukoresha ibikoresho byujuje ibisabwa hejuru kandi ukore ibyemezo bishoboka mbere yumusaruro.
Amavuta arambuye / ingese amavuta yo gukumira akoreshwa mu musaruro akunda guhindagurika. Nyuma yo gufungura ibipapuro bipfunyika, bigomba gukoreshwa ako kanya cyangwa bigasukurwa kandi bigasiga amavuta mbere yo gutera kashe.
Ubuso bukunda okiside kandi ntibugomba kubikwa kumugaragaro. Ubuyobozi bwihariye (gupakira) burakenewe.
3 Ibisabwa bya tekinike kumpapuro za kashe ya Aluminium muri Welding
Inzira nyamukuru yo gusudira mugihe cyo guteranya imibiri ya aluminiyumu harimo gusudira kurwanya, gusudira kwa CMT gukonje, gusudira tungsten inert (TIG) gusudira, kuzunguruka, gukubita, no gusya / gusya.
3.1 Gusudira utanyeganyega kumpapuro za Aluminium
Urupapuro rwa aluminiyumu rutanyeganyega rukozwe no gukonjesha gukonje ibice bibiri cyangwa byinshi byimpapuro zicyuma ukoresheje ibikoresho byumuvuduko nububiko bwihariye. Iyi nzira irema guhuza ingingo hamwe ningingo zingana kandi zogosha. Umubyimba wimpapuro zihuza urashobora kuba umwe cyangwa zitandukanye, kandi zirashobora kugira ibice bifatanye cyangwa ibindi bice bigereranijwe, hamwe nibikoresho bimwe cyangwa bitandukanye. Ubu buryo butanga amasano meza adakeneye umuhuza wungirije.
3.2 Kudoda
Kugeza ubu, gusudira kwa aluminiyumu ikoreshwa muri rusange ikoresha uburyo bwo gusudira hagati cyangwa inshuro nyinshi. Ubu buryo bwo gusudira bushonga icyuma fatizo murwego rwa diameter ya electrode yo gusudira mugihe gito cyane kugirango ikore pisine,
gusudira ahantu hakonje vuba kugirango habeho guhuza, hamwe nibishoboka bike byo kubyara umukungugu wa aluminium-magnesium. Ibyinshi mu byuka byo gusudira byakozwe bigizwe nuduce twa oxyde duhereye hejuru yicyuma hamwe nubutaka bwanduye. Umwuka uhumeka waho utangwa mugihe cyo gusudira kugirango ukureho vuba ibyo bice mu kirere, kandi hariho imyanda mike ya aluminium-magnesium.
3.3 Ubushuhe bwo gukonjesha CMT hamwe no gusudira TIG
Izi nzira ebyiri zo gusudira, kubera kurinda gaze ya inert, zitanga uduce duto duto twa aluminium-magnesium ku bushyuhe bwinshi. Ibi bice bishobora kwisuka mubikorwa bikora munsi ya arc, bigatera ibyago byo guturika kwa aluminium-magnesium. Niyo mpamvu, ingamba n'ingamba zo gukumira no guturika ivumbi birakenewe.
4 Ibisabwa bya tekinike kumpapuro za kashe ya Aluminium muri Rolling
Itandukaniro riri hagati ya aluminium alloy impande zuzunguruka hamwe nibisanzwe bikonje bikonje impapuro zuzunguruka ni ngombwa. Aluminium ntigabanuka cyane kuruta ibyuma, bityo rero umuvuduko ukabije ugomba kwirinda mugihe cyo kuzunguruka, kandi umuvuduko wo kuzunguruka ugomba kuba gahoro gahoro, mubisanzwe 200-250 mm / s. Buri nguni izunguruka ntigomba kurenga 30 °, kandi igomba kwirinda kuzunguruka.
Ubushuhe busabwa kugirango aluminiyumu izunguruke: Igomba gukorwa ku bushyuhe bwa 20 ° C. Ibice byafashwe mububiko bukonje ntibigomba guhita bizunguruka.
Imiterere 5 n'ibiranga Impande zizunguruka kumpapuro za kashe ya Aluminium
5.1 Imiterere yo Kuzenguruka Impapuro za kashe ya Aluminium
Kuzunguruka bisanzwe bigizwe nintambwe eshatu: intangiriro yo kuzunguruka, iyambere-kuzunguruka, no kuzunguruka kwa nyuma. Ibi mubisanzwe bikoreshwa mugihe nta mbaraga zisabwa zisabwa kandi impande zinyuma zisa nibisanzwe.
Kuzunguruka-muburyo bwiburayi bigizwe nintambwe enye: intangiriro-kuzunguruka, icyiciro cya kabiri mbere yo kuzunguruka, kuzunguruka kwa nyuma, no kuzunguruka-byuburayi. Ibi mubisanzwe bikoreshwa mukuzenguruka-ndende, nk'imbere n'inyuma. Kuzunguruka muburyo bwiburayi birashobora kandi gukoreshwa mukugabanya cyangwa gukuraho inenge zubuso.
5.2 Ibiranga uruziga ruzengurutse impapuro za kashe ya Aluminium
Kubikoresho bya aluminiyumu bizunguruka, ibumba ryo hasi hamwe no gushyiramo blok bigomba guhanagurwa no kubungabungwa buri gihe hamwe na 800-1200 # sandpaper kugirango harebwe niba nta bikoresho bya aluminiyumu bihari hejuru.
Impamvu 6 zitandukanye zitera inenge zatewe na Edge Rolling yimpapuro za kashe ya Aluminium
Impamvu zitandukanye zitera inenge ziterwa no kuzenguruka ibice bya aluminiyumu bigaragara kumeza.
7 Ibisabwa bya tekinike yo gutwikira impapuro za kashe ya Aluminium
7.1 Amahame n'ingaruka zo Gukaraba Amazi Kumashanyarazi ya Aluminium
Amazi yo gukaraba yerekana kuvanaho firime isanzwe ya okiside hamwe namavuta yamavuta hejuru yibice bya aluminiyumu, kandi binyuze mumiti ya chimique hagati ya aluminiyumu n'umuti wa acide, bigakora firime yuzuye ya oxyde hejuru yakazi. Filime ya oxyde, irangi ryamavuta, gusudira, hamwe no gufatira hamwe hejuru yibice bya aluminiyumu nyuma yo gutera kashe byose bigira ingaruka. Kugirango urusheho gufatira hamwe no gusudira, hakoreshwa uburyo bwa chimique kugirango habeho guhuza igihe kirekire no guhuza imbaraga ku butaka, bigera ku gusudira neza. Kubwibyo, ibice bisaba gusudira laser, gusudira ibyuma bikonje (CMT), hamwe nubundi buryo bwo gusudira bigomba gukorerwa passivation yo gukaraba amazi.
7.2 Gutunganya Amazi yo Gukaraba Amashanyarazi kumpapuro za kashe ya Aluminium
Ibikoresho byo gukaraba amazi bigizwe n’ahantu habi, ahantu ho gukaraba amazi mu nganda, ahantu nyabagendwa, ahantu hogeza amazi meza, ahantu humye, hamwe na sisitemu yo kuzimya. Ibice bya aluminiyumu bigomba kuvurwa bishyirwa mu gitebo cyo gukaraba, bigashyirwaho, bikamanurwa mu kigega. Mu bigega birimo ibishishwa bitandukanye, ibice byogejwe inshuro nyinshi hamwe nibisubizo byose bikora muri tank. Ibigega byose bifite pompe zizenguruka hamwe na nozzles kugirango habeho kwoza ibice byose. Amazi yo gukaraba amazi atemba ni aya akurikira: gutesha agaciro 1 → gutesha agaciro 2 → gukaraba amazi 2 → gukaraba amazi 3 → passivation wash gukaraba amazi 4 → gukaraba amazi 5 → gukaraba amazi 6 → gukama. Ibikoresho bya aluminiyumu birashobora gusimbuka gukaraba amazi 2.
7.3 Uburyo bwo Kuma Amazi yo Kwoza Amabati ya Aluminium
Bifata iminota igera kuri 7 kugirango ubushyuhe bwigice buzamuke kuva mubushyuhe bwicyumba kugera kuri 140 ° C, kandi igihe ntarengwa cyo gukira kumiti ni iminota 20.
Ibice bya aluminiyumu bizamurwa kuva mubushyuhe bwicyumba kugera ku bushyuhe bwo gufata mu minota igera ku 10, kandi igihe cyo gufata aluminium ni iminota 20. Nyuma yo gufata, ikonjeshwa kuva ubushyuhe bwo kwifata kugeza kuri 100 ° C muminota igera kuri 7. Nyuma yo gufata, ikonjeshwa ubushyuhe bwicyumba. Kubwibyo, inzira yose yo kumisha ibice bya aluminium ni iminota 37.
8 Umwanzuro
Imodoka zigezweho ziratera imbere zoroheje, zihuta cyane, umutekano, zorohewe, zihenze cyane, imyuka ihumanya ikirere, hamwe n’icyerekezo gikoresha ingufu. Iterambere ry’inganda zitwara ibinyabiziga rifitanye isano rya bugufi no gukoresha ingufu, kurengera ibidukikije, n’umutekano. Hamwe no kurushaho kumenyekanisha kurengera ibidukikije, ibikoresho bya aluminiyumu bifite inyungu ntagereranywa mu biciro, ikoranabuhanga mu nganda, imikorere y’imashini, n’iterambere rirambye ugereranije n’ibindi bikoresho byoroheje. Kubwibyo, aluminiyumu izahinduka ibikoresho byoroheje byoroheje mu nganda zitwara ibinyabiziga.
