Mu mafakitale apadziko lonse lapansi a migodi, migodi, ndi kukonza zinthu zonse, nthawi yogwiritsira ntchito zida zophwanyira chitsulo imatsimikiza mwachindunji momwe zinthu zimagwirira ntchito, nthawi yogwira ntchito, komanso mtengo wonse wa umwini (TCO). Posankha zida zophwanyira chitsulo monga mbale za jaw, ma cone liners, blow bars, ndi nsonga za nyundo, ogwiritsa ntchito ambiri amayang'ana kwambiri kapangidwe ka zinthu, monga chitsulo cha manganese kapena kuchuluka kwa chromium, koma amanyalanyaza chinthu chofunikira chomwe chimalamulira magwiridwe antchito omaliza a chinthucho: chithandizo cha kutentha. Deta ya metallurgical yamakampani ikuwonetsa kuti ngakhale ndi mankhwala ofanana, zida ziwiri zophwanyira chitsulo zimatha kukhala ndi kusiyana kwa 50-100% pa moyo wa ntchito, chifukwa cha kusiyana kwa njira zochizira kutentha. Kwa ogwiritsa ntchito zida zophwanyira chitsulo, kumvetsetsa udindo wa chithandizo cha kutentha sikungokhala chidziwitso chaukadaulo - ndi chida chofunikira kwambiri posankha zida zophwanyira chitsulo zapamwamba ndikupewa kulephera kokwera mtengo msanga. Nkhaniyi ikulongosola mfundo zazikulu zochizira kutentha kwa zida zophwanyira chitsulo, njira zodziwika bwino za zipangizo zazikulu, komanso momwe chithandizo cha kutentha chokonzedwa bwino chimaperekera phindu logwira ntchito.
Chifukwa Chake Kutentha Sikungatheke Kukambirana pa Zida Zovala za Crusher
Zigawo zosweka monga momwe zimakhalira, kuchokera ku nkhungu ya foundation, zimakhala ndi kapangidwe kosasunthika ka zitsulo, kolimba kosagwirizana, kupsinjika kwamkati, ndi ma carbide ofooka omwe amalepheretsa magwiridwe antchito kwambiri. Kusamalira kutentha ndi njira yolamulidwa ya zitsulo yomwe imagwiritsa ntchito kutentha, kugwira, ndi kuziziritsa kolondola kuti isinthe kapangidwe ka mkati mwa chitsulo, ndikutsegula mphamvu zonse za zinthu zake zosungunulira. Vuto lalikulu la zigawo zonse zosweka za crusher ndikulinganiza zinthu ziwiri zotsutsana: kukana kusweka kuti zipirire kudula kuchokera ku mwala wolimba, ndi kulimba kuti zipirire kusweka pamene zikugwedezeka kwambiri. Popanda chithandizo choyenera cha kutentha, kulinganiza kumeneku sikungatheke. Mwachitsanzo, kuponyera kwa chromium yambiri kungakhale ndi kukana bwino kusweka, koma popanda chithandizo chabwino cha kutentha, kudzakhala kosweka kwambiri kuti kupirire ngakhale kugwedezeka pang'ono, zomwe zimapangitsa kuti kusweka kapena kusweka kuwonongeke kwambiri pakati pa ntchito.
Njira Zochiritsira Kutentha Zachikhalidwe pa Zida Zovala Zazikulu
Chida chilichonse chosawonongeka chimakhala ndi njira yapadera yochizira kutentha, yokonzedwa molingana ndi kapangidwe kake ka mankhwala ndi momwe chimagwiritsidwira ntchito. Kwa akatswiri opanga zinthu zopangira zitsulo, kutsatira kwambiri njirazi ndiye maziko a zida zogwirira ntchito bwino komanso zogwirizana nthawi zonse.
Choyamba, kulimbitsa madzi pa chitsulo cha austenitic manganese, muyezo wagolide wa zigawo zoyamba zophwanyira. Zitsulo za Manganese, kuphatikizapo Mn13Cr2 yomwe imagwiritsidwa ntchito kwambiri ndi Mn18Cr2 yolimba kwambiri, zimadalira kapangidwe ka austenitic ka gawo limodzi kuti zipereke mphamvu yawo yolimba: zikakhudzidwa kwambiri, pamwamba pake pamakhala wolimba kuti zisawonongeke, pomwe pakati pake pamakhalabe wolimba kuti pasasweke. Njira yolimbitsa madzi imafuna kutenthetsa kuponyedwa kwa chitsulocho kufika pa 1050-1100°C, kuisunga kutentha kumeneku kuti isungunuke ma carbides mu matrix, kenako kuzimitsa mwachangu m'madzi kuti zitseke mu kapangidwe ka austenitic. Ngakhale kusintha pang'ono, monga nthawi yokwanira yogwira kapena kuzizira pang'onopang'ono, kungayambitse mapangidwe a carbide, kuchepetsa kulimba kwa gawolo ndi 70% ndikupangitsa kuti liwonongeke mwadzidzidzi.
Chachiwiri, kuzimitsa ndi kutenthetsa chitsulo choyera chokhala ndi chromium yambiri, choyenera kuphwanyidwa kwambiri, kuphwanyidwa kochepa komanso kwachitatu. Kukana kwapadera kwa chitsulo chokhala ndi chromium yambiri kumachokera ku tinthu take tolimba ta chromium carbide ndi martensitic matrix. Njira yochizira kutentha imaphatikizapo kuzungulira kozimitsa koyendetsedwa bwino kuti apange kapangidwe ka martensitic, kutsatiridwa ndi sitepe yochepetsera kupsinjika kwamkati ndikuchepetsa austenite yosungidwa. Njirayi imalinganiza kuuma kwakukulu kwa kukana kuphwanyidwa ndi kulimba kokwanira kuti isagwe, zomwe zimapangitsa kuti ntchito ikhale yayitali katatu kuposa chitsulo chokhazikika cha manganese mu ntchito zozimitsa kwambiri.
Ubwino Wooneka wa Kutentha Koyenera
Kwa ogwiritsa ntchito makina opopera, kuyika ndalama mu zida zogwiritsidwa ntchito popopera pogwiritsa ntchito kutentha koyenera kumabweretsa phindu la ndalama komanso magwiridwe antchito. Zimawonjezera nthawi yogwirira ntchito ndi 30-80% poyerekeza ndi zida zomwe zimagwiritsidwa ntchito popopera kutentha kosayenera, kuchepetsa kuchuluka kwa nthawi yosinthira ndi ndalama zogwirira ntchito. Zimachotsanso nthawi yogwira ntchito yosakonzekera yomwe imabwera chifukwa cha kusweka kwadzidzidzi kwa zida, vuto lofala ndi zida zogwiritsidwa ntchito mosayenera kutentha zomwe zingawononge ndalama zambirimbiri zomwe zimatayika pa ola limodzi. Pomaliza, zimachepetsa TCO yonse: pomwe zida zogwiritsidwa ntchito popopera kutentha kwambiri zitha kukhala ndi mtengo wokwera pang'ono pasadakhale, zimapereka nthawi yayitali yogwirira ntchito nthawi ziwiri kapena zitatu, kuchepetsa ndalama zomwe zimagwiritsidwa ntchito pachaka ndi 40%.
Ku Shanghai Haocheng Machinery Parts Co., Ltd., timaona kutentha ngati chinthu chofunikira kwambiri popanga zinthu zosweka. Kampani yathu yopangira zitsulo ili ndi ng'anjo zotenthetsera kutentha zomwe zimayendetsedwa bwino ndi kutentha, ndipo gulu lathu la akatswiri opanga zitsulo limapanga njira zotenthetsera kutentha zomwe zingagwiritsidwe ntchito pa kapangidwe ka zinthu ndi zigawo zake. Gulu lililonse la zida zathu zosweka limayesedwa mwamphamvu pambuyo pa kutentha, kuphatikizapo kuyeza kuuma ndi kusanthula kwa metallographic, kuti zitsimikizire kuti zikugwira ntchito bwino komanso mogwirizana ndi zinthu zovuta kwambiri.
Pomaliza, kapangidwe ka zinthu ndi poyambira pa gawo lapamwamba kwambiri lophwanyira chitsulo—kutentha koyenera ndiko komwe kumasintha kupopera kwabwino kukhala gawo lodalirika komanso lokhalitsa. Mwa kuyika patsogolo khalidwe la kutentha posankha ogulitsa magawo ophwanyira chitsulo, ogwiritsa ntchito amatha kupeza phindu lalikulu komanso kusunga ndalama pa ntchito zawo zophwanyira chitsulo.
