Ezimbonini zomhlaba wonke zezimayini, ukumba, kanye nokucubungula okuhlanganisiwe, impilo yesevisi yezingxenye zokugqoka ze-crusher inquma ngqo ukusebenza kahle kokukhiqiza, isikhathi sokungasebenzi, kanye nezindleko eziphelele zobunikazi (i-TCO). Lapho ukhetha izingxenye zokugqoka ezifana namapuleti emihlathi, ama-cone liner, ama-blow bars, kanye namathiphu e-hammer, iningi labasebenzi ligxila kakhulu ekwakhiweni kwezinto, njenge-manganese steel grade noma okuqukethwe kwe-chromium, kodwa likhohlwa isici esibalulekile esinquma ukusebenza kokugcina kwengxenye: ukwelashwa kokushisa. Idatha ye-metallurgical yemboni ikhombisa ukuthi ngisho namakhemikhali afanayo, izingxenye ezimbili zokugqoka zingaba nomehluko ongu-50-100% empilweni yesevisi, ngenxa yokwehluka kwezinqubo zokwelapha ukushisa. Kwabasebenzi be-crusher, ukuqonda indima yokwelashwa kokushisa akuyona nje ulwazi lobuchwepheshe—kuyithuluzi elibalulekile lokukhetha izingxenye zokugqoka ezisezingeni eliphezulu nokugwema ukwehluleka okubizayo ngaphambi kwesikhathi. Lesi sihloko siphula izimiso eziyinhloko zokwelashwa kokushisa kwezingxenye zokugqoka ze-crusher, izinqubo ezijwayelekile zezinto ezivamile, nokuthi ukwelashwa kokushisa okulungiselelwe kuletha kanjani izinzuzo zokusebenza ezibonakalayo.
Kungani Ukwelashwa Kokushisa Kungaxoxiswani Ngezingxenye Zokugqoka Ze-Crusher
Izingxenye zokuguguleka ezifakwe njenge-cast, zisuka ngqo esikhumbeni se-foundry, zinesakhiwo se-metallurgical esingazinzile, esinobunzima obungalingani, ukucindezeleka okusele kwangaphakathi, kanye nokwehla kwe-carbide okuqhekeka okukhawulela kakhulu ukusebenza. Ukwelashwa ngokushisa kuyinqubo elawulwayo ye-metallurgical esebenzisa imijikelezo eqondile yokushisa, yokubamba, kanye nokupholisa ukushintsha isakhiwo sangaphakathi sensimbi, ivula amandla aphelele ezingxenye zayo ze-alloy. Inselele eyinhloko yazo zonke izingxenye zokuguguleka kwe-crusher ukulinganisa izakhiwo ezimbili eziphikisanayo: ukumelana nokuguguleka ukuze kumelwane nokusikwa edwaleni eliqinile, kanye nokuqina kokumelana nokuphuka ngaphansi komthelela omkhulu. Ngaphandle kokwelashwa okufanele ngokushisa, lokhu kulinganisela akunakwenzeka ukukufeza. Isibonelo, ukuthungwa kwe-chromium ephezulu kungaba nokumelana okuhle kakhulu nokuguguleka, kodwa ngaphandle kokwelashwa ngokushisa okulungiselelwe, kuzoba buthakathaka kakhulu ukuze kumelwane ngisho nomthelela ophakathi, okuholela ekuqhekekeni okubi noma ukuphuka phakathi nokusebenza.
Izinqubo Ezijwayelekile Zokwelapha Ukushisa Zezinto Ezisetshenziswa Kakhulu Zokugqoka Ingxenye
Into ngayinye engagugi inenqubo yokwelapha ukushisa ehlukile, eyenzelwe ukwakheka kwayo kwamakhemikhali kanye nokusetshenziswa okuhlosiwe. Kwabasunguli bobuchwepheshe, ukunamathela ngokuqinile kulezi zinqubo kuyisisekelo sezingxenye ezihambisanayo nezisebenza kahle kakhulu.
Okokuqala, ukuqinisa amanzi kwensimbi ye-austenitic manganese, indinganiso yegolide yezingxenye eziyinhloko zokuchoboza. Izinsimbi ze-Manganese, okuhlanganisa i-Mn13Cr2 esetshenziswa kabanzi kanye ne-Mn18Cr2 eqinile, zithembele esakhiweni esincane se-austenitic sesigaba esisodwa ukuze zinikeze isici sazo esibalulekile sokuqinisa umsebenzi: lapho zibhekene nokushayisana okukhulu, ubuso buyaqina ukuze bumelane nokuguguleka, kuyilapho umongo uhlala uqinile ukuze uvimbele ukuqhekeka. Inqubo yokuqinisa amanzi idinga ukufudumeza ukuphonswa ku-1050-1100°C okunembile, ukuyibamba kuleli zinga lokushisa ukuze kuncibilikiswe ama-carbide ku-matrix, bese uyicima ngokushesha emanzini ukuze ivale isakhiwo se-austenitic. Ngisho nokuphambuka okuncane, njengokungabi nesikhathi esanele sokubamba noma ukupholisa kancane, kuzokwenza ukuthi kwakheke ukuqhekeka kwe-carbide, kunciphisa ukuqina kwengxenye kufike ku-70% futhi kwenze kube lula ukuphuka ngokuzumayo.
Okwesibili, ukucima nokushisa insimbi emhlophe ecijile ene-chromium ephezulu, efanelekile ekuchotshozweni okuphezulu, okunomthelela ophansi kwesibili kanye nokuphezulu. Ukumelana nokuguguleka okumangalisayo kwensimbi ephezulu ene-chromium kuvela ezinhlayiyeni zayo ze-chromium carbide eqinile kanye ne-martensitic matrix. Inqubo yokwelapha ukushisa ihilela umjikelezo wokucima olawulwa ngokucophelela ukuze kwakhiwe isakhiwo se-martensitic, kulandelwe yisinyathelo sokupholisa ukuze kuncishiswe ukucindezeleka kwangaphakathi futhi kuncishiswe i-austenite egcinwe ngokuphuka. Le nqubo ilinganisela ubulukhuni obukhulu bokumelana nokuguguleka ngokuqina okwanele ukugwema ukuqhekeka, okunikeza impilo yenkonzo ende izikhathi eziphindwe kathathu kunensimbi ejwayelekile ye-manganese ekusetshenzisweni okuphezulu kokuguguleka.
Izinzuzo Ezibonakalayo Zokwelashwa Kokushisa Okuthuthukisiwe
Kwabasebenzi be-crusher, ukutshala imali ezingxenyeni ezigugile ngokwelashwa kokushisa okulawulwa ngokuqinile kuletha izinzuzo zezimali nezokusebenza ezilinganisekayo. Kwandisa impilo yesevisi ngo-30-80% uma kuqhathaniswa nezingxenye ezine-heat treatment engaphansi kwejwayelekile, kunciphisa imvamisa yokushintsha kanye nezindleko zomsebenzi ezihambisanayo. Kuphinde kuqede isikhathi sokungasebenzi esingahleliwe esibangelwa ukuphuka kwezingxenye ngokuzumayo, inkinga evamile ngezingxenye ezingaphathwanga kahle ngokushisa ezingabiza ama-grand aphakathi nendawo ekukhiqizweni okulahlekile ngehora. Okokugcina, kunciphisa i-TCO iyonke: ngenkathi izingxenye eziphathwa ngokushisa ezisezingeni eliphezulu zingase zibe nezindleko eziphezulu kusengaphambili, ziletha impilo yesevisi ende izikhathi eziphindwe kabili kuya kwezithathu, zinciphisa ukusetshenziswa kwezingxenye zonyaka ezigugile ngamaphesenti afinyelela ku-40%.
Kwa-Shanghai Haocheng Machinery Parts Co., Ltd., sibheka ukwelashwa kokushisa njengento eyinhloko yenqubo yethu yokukhiqiza izingxenye zokuguguleka. I-foundry yethu ifakwe izitofu zokwelapha ukushisa ezilawulwa ngokushisa okunembile, futhi ithimba lethu le-metallurgical lakha imijikelezo yokwelapha ukushisa eyenzelwe wena kuyo yonke into kanye nomklamo wezingxenye. Iqoqo ngalinye lezingxenye zethu zokuguguleka lihlolwa ngokuqinile ukwelashwa kokushisa ngemva kokushisa, okuhlanganisa ukulinganiswa kobulukhuni kanye nokuhlaziywa kwe-metallographic, ukuqinisekisa ukusebenza okuqhubekayo okuhlangabezana nezimo zokuchotshozwa ezidinga kakhulu.
Ekuphetheni, ukwakheka kwezinto kumane kuyisiqalo sengxenye yokuguguleka kwe-crusher esezingeni eliphezulu—ukwelashwa kokushisa okufanele yikho okuguqula ukuthungwa okuhle kube yingxenye ethembekile nehlala isikhathi eside. Ngokubeka phambili ikhwalithi yokwelashwa kokushisa lapho kukhethwa abahlinzeki bezingxenye zokuguguleka, abaqhubi bangavula izinzuzo ezinkulu zokusebenza kahle kanye nokonga izindleko zemisebenzi yabo yokuchoboza.
