Makampani Ogulitsa Zitsulo

Mbiri Yamakampani

Malo ogwirira ntchito m'mafakitale a zida zofunika kwambiri zamagetsi ndi ovuta kwambiri, omwe amadziwika ndi kutentha kwambiri, katundu wolemera, kukhudzidwa kwambiri, kutentha nthawi zambiri, komanso dzimbiri chifukwa cha kuzizira. Izi nthawi zambiri zimapezeka m'magawo monga kupanga zitsulo, migodi, ndi makina olemera, komwe zida zimakhala ndi kupsinjika kosalekeza komanso kuwononga chilengedwe. Malo otentha kwambiri amaposa 500°C nthawi zambiri, zomwe zimapangitsa kuti zinthu zifewetsedwe komanso kufulumizitsa zochita za mankhwala, pomwe kutentha (kusinthasintha kwa kutentha kopitilira 300°C pa kuzungulira) kumayambitsa kupsinjika kwa kutentha komwe kumafooketsa umphumphu wa kapangidwe kake. Machitidwe ozizira, nthawi zambiri amagwiritsa ntchito njira zamadzimadzi zokhala ndi ma ayoni owononga (monga, Cl⁻, SO₄²⁻), amapanga mawonekedwe awiri a kuwonongeka kwa makina ndi dzimbiri la mankhwala.

Mitundu ya Zigawo ndi Njira Zolephera

Zinthu zofunika kwambiri zomwe zimagwira ntchito pansi pa mikhalidwe iyi ndi monga ma roller (omwe amagwiritsidwa ntchito mu mphero zozungulira popanga zitsulo), ma laminar roller (ofunikira kwambiri poyendetsa zinthu molamulidwa mumizere yoyeretsera kutentha), ma guide plate (kuonetsetsa kuti zinthu zikugwirizana bwino), ma guide Guard (kuteteza ziwalo zoyenda ku kugundana kwa mbali), ndi ma guide wheel (kuthandiza kunyamula zinthu mopanda kugwedezeka kwambiri). Njira zawo zolephera zili ndi mbali zambiri:

● Kuwonongeka kwa dzimbiri zimachitika pamene zinthu zapamwamba zimagwirizana ndi zinthu zowononga, ndikupanga zigawo zofooka za oxide zomwe zimatuluka pansi pa katundu, zomwe zimawonjezera kukangana ndi 40%.

● Kutopa kwambiri Zimachitika chifukwa cha kudzaza kwa cyclic (kupitirira 10⁶ stress cycles), zomwe zimapangitsa kuti ming'alu iyambe komanso kufalikira pansi pa nthaka, makamaka m'malo olumikizirana ndi kupsinjika (monga, m'mphepete mwa ma roller).

● Kusweka kwa mafupa Kawirikawiri zimachitika chifukwa cha kupsinjika kwa kutentha ndi makina, ndipo kuchuluka kwa kulephera kumakwera ndi 30% m'zigawo zomwe zimakhala ndi kusintha kwadzidzidzi kwa kutentha.

● Kutentha kwambiri Zimaphatikizapo njira zomatira ndi zokwawa pa kutentha kwakukulu, zomwe zimapangitsa kuti kuuma kwa pamwamba kuwonjezereke ndi 50-80% ndikuchepetsa kulondola kwa miyeso.

Mayankho Ochokera ku Laser Othandizira Kupititsa Patsogolo Magwiridwe Antchito

Pofuna kuthana ndi mavutowa, ukadaulo wa laser surface umapereka njira zamakono:

1. Kuphimba ndi laser

Njira imeneyi ndi yabwino kwambiri polimbitsa ndi kupanganso zinthu zamtengo wapatali monga ma rollers, ma laminar rollers, ma transmission rollers, ma universal joints, ndi ma rolling mill arches. Mzere wa laser wamphamvu kwambiri umasungunuka ndikuyika ufa wapadera wa alloy wosawonongeka kutentha kwambiri (monga cobalt-chromium, nickel-based superalloys) pamwamba pa substrate, ndikupanga mgwirizano wolimba wachitsulo. Ubwino waukulu ndi uwu:

● Kuchepa kwa kusungunuka kwa madzi (

● Kusintha kochepa (kupotoza kutentha

● Kugwira ntchito bwino kwambiri pophimba (kuchuluka kwa malo osungira mpaka 500 cm³/h), zomwe zimathandiza kupanga kapena kukonza mwachangu zinthu zazikulu. Zigawo zophimbazo zimakhala ndi kuuma kwa 60-70 HRC ndipo zimatha kupirira ntchito yopitilira pa 800-1000°C, zomwe zimapangitsa kuti zinthuzo zikhale ndi moyo nthawi 2-3 poyerekeza ndi zophimba zachizolowezi.

2. Kuyika ndi laser

Pofuna kulimbitsa pamwamba pa ma rollers ndi ma rollers odulira, laser alloying imapereka njira yotsika mtengo. Njirayi imaphatikizapo kusungunula pamwamba pa substrate pamodzi ndi zinthu zodulira (monga carbides, nitrides) kuti apange chophimba chachitsulo-ceramic chopanda zigawo zazikulu zakunja. Zinthu zodziwika bwino ndi izi:

● Kuyenda kosavuta kwa njira, komwe kumafuna kuyika ufa kapena mawaya a alloying pasadakhale, kuchepetsa nthawi yokonzekera ndi 20%.

● Kugwirizana kwamphamvu kwa zitsulo (mphamvu yocheka >500 MPa), kuonetsetsa kuti kukana bwino kugwedezeka ndi kutentha.

● Kugwiritsa ntchito bwino ndalama, chifukwa kugwiritsa ntchito zinthu kumachepetsedwa pamene zinthuzo zikukwaniritsidwa: kukana kuwonongeka kwa zinthu kumawonjezeka ndi 30%, kukana dzimbiri m'malo okhala ndi madzi amchere kumawonjezeka ndi 40%, ndipo kukana okosijeni pa 600°C kumawonjezeka ndi 50%.

Ukadaulo wa laser uwu ndi njira yosinthira zinthu polimbana ndi mavuto a mafakitale, kupereka mayankho okhazikika omwe amalinganiza magwiridwe antchito, kudalirika, komanso kugwiritsa ntchito bwino ndalama pazinthu zofunika kwambiri zamakanika.
