Inganda z'ubucukuzi bw'amabuye y'agaciro

Isesengura ry'imikorere y'ikoranabuhanga rya Laser Cladding mu nganda n'amakuru ajyanye naryo

1. Isesengura ry'amateka y'inganda

1. Ingaruka z'ahantu habi ho gukorera ku bikoresho

Ahantu ho gucukura amakara munsi y'ubutaka hatera imbogamizi zikomeye ku kuramba kw'imashini. Kubera ko ubushuhe bukunze kurenga 90% kandi hakaba hari imyuka yangiza nka H₂S na SO₂, ibice by'icyuma bihura n'ingufu zihuse za electrochemical. Urugero, silindiri za hydraulic prop, z'ingenzi mu kubungabunga ubusugire bw'imiyoboro, zikunze guhura n'ingufu zo hejuru zigatuma imikorere yo kuzifunga igabanuka, bigatuma sisitemu ya hydraulic inanirwa. Byongeye kandi, uduce tw'umukungugu w'amakara (ubukana bwa Mohs 3-4) dukora nk'ibintu bitera kwangirika gukomeye ku bice by'amashanyarazi nka sprockets na scrapers. Umukungugu w'amakara wihuta cyane ushobora kugabanya igihe cy'imikorere y'ibi bice kugeza kuri 40% ugereranije n'ahantu hasukuye.

2. Uburyo ibice binanirwa gukora

(1) Kwambara umunaniro: Gushyira ibintu ku buryo buzenguruka ku duce duto tw’imashini n’udupira duto (scrapers) bituma habaho uduce duto tw’imashini duto ku buso. Nyuma y’amasaha agera ku 1.000 yo gukora, utu duce dushobora kwinjira mu burebure bwa mm 0.5, bigatuma ibintu bicika ndetse n’imikorere yabyo ikangirika.

(2) Gusibanganya irangi: Imiterere gakondo ikozwe mu buryo bw'amashanyarazi (urugero, icyuma gikomeye cya chrome) ihuzwa mu buryo budakomeye n'ibice bya substrate (20-30 MPa), bigatuma bishobora gushwanyagurika iyo bikubiswe. Mu buryo bunyuranye, icyuma gikingira imirasire ya laser gitanga imbaraga zo guhuza za 400-600 MPa, bigatuma gifatana igihe kirekire.

2. Ibyiza by'ikoranabuhanga ryo gupfuka imigozi hakoreshejwe laser

Gupfuka imigozi ya laser yo hanze

Ubu buryo burahebuje mu gutegura irangi ririnda kwangirika no kwangirika ku bice by'umugozi nka silindiri n'inkoni za piston. Ibyiza by'ingenzi birimo:

● Igipimo gito cyo gushonga: Munsi ya 5%, bibungabunga imiterere y'ibikoresho by'umwimerere.

● Guhinduka guke: Uduce twibasirwa n'ubushyuhe akenshi tuba turi munsi ya mm 0.5, tugakomeza kugira imiterere ihamye.

● Uburyo bwo gukoresha neza ibikoresho: Igipimo cy'ikoreshwa ry'ifu kirenga 90%, bigabanya ikiguzi ugereranije n'ikoreshwa risanzwe.

● Ubwiza bw'ubuso: Irangizwa rya Ra ≤ 6.3μm, bikuraho ko hakenewe irangizwa rya nyuma mu bihe byinshi.

Igipfundikizo cya Laser cyo mu Rukuta rw'Imbere

Ubu buryo ni bwiza cyane kuri silindiri za hydraulic na piston rods, kandi butuma habaho ikoreshwa ry'amabara atandukanye (urugero: icyuma kitagira umugese, aloyi zishingiye kuri nikeli) zifite ubunini buri hagati ya mm 0.5 na mm 3. Urugero:

● Imyambaro y'icyuma kidashonga: Gutanga ubushobozi bwo kurwanya ingese inshuro 5 kurusha icyuma cyambaye ubusa mu duce duto dukorerwamo aside.

● Aloyi zishingiye kuri nikeli: Ongera ubukana kuva kuri 200 HV kugera kuri 600 HV, bikongera cyane ubushobozi bwo kudashira.

Igipfundikizo cya Laser cyo hejuru gifite imiterere igoranye

Iyi gahunda yagenewe imiterere y’ibishushanyo mbonera igoye nka sprockets na picks, itanga:

● Igenzura ry’Inzira Ihindagurika: Ikoresha sisitemu za CNC zifite umurongo 5 kugira ngo igere ku bunini bumwe bwo gusiga (± 0.1mm) ku buso butaringaniye.

● Imbaraga nyinshi z'ubumwe: Guhuza ibyuma bifasha mu kurwanya imitwaro y’inkongi. Urugero, ibice bipfutse ku mapiki bigumana ubuziranenge nubwo byaba biri munsi ya 200 J by’ingufu z’inkongi.

3. Ibipimo bya tekiniki n'ibipimo by'imikorere

4. Inyigo y'Urugero: Gusana Silindari yo Gutunganya Hydraulic Prop

Ikirombe cy'amakara mu Ntara ya Shanxi cyatangaje ko ikiguzi cyo gusimbuza silinda cyagabanutseho 65% nyuma yo gukoresha uburyo bwo gusimbuza hakoreshejwe laser. Ubu buryo bwasubije silinda zari zarangiritse (zari zifite φ140mm×2.5m) ku buryo bworoshye gukoreshwa, aho urwego rwazo (NiCrBSi alloy, 1.2mm y'ubugari) rwagaragaje:

● 86% by'ubushyuhe buri hasi ugereranyije n'icyuma cy'umwimerere.

● Igihe cyo kubaho inshuro 3 mu gihe cyo gupima kwangirika kw'ingufu.

● Igipimo cya 100% cyo gutsinda mu bizamini byo gufunga hakoreshejwe umuvuduko mwinshi (35 MPa).

5. Inyungu ku bidukikije n'ubukungu

● Kuzigama ibikoresho: Gupfuka imitako hakoreshejwe laser bikoresha ifu y’inzoga ntoya ku kigero cya 70% ugereranije n’uburyo busanzwe bwo gupfuka imitako.

● Gukoresha neza ingufu: Igabanya ikoreshwa ry'ingufu ku kigero cya 40% mu gihe cyo gusana.

● Kugabanya imyuka ihumanya: Ikuraho imyuka ya chromium hexavalent ijyanye no gukoresha electroplating, ikurikije amategeko akaze agenga ibidukikije.

Muri make, ikoranabuhanga ryo gupfuka imirasire ya laser ritanga igisubizo cyuzuye cyo kurwanya kwangirika kw'ibice mu bucukuzi bukomeye bw'amabuye y'agaciro, ritanga imikorere myiza kandi irambye ugereranije n'uburyo gakondo.
