Kwimizi-mveliso yezemigodi yehlabathi, ukumba, kunye nokucubungula aggregate, ubomi benkonzo yezixhobo zokugquma bumisela ngokuthe ngqo ukusebenza kakuhle kwemveliso, ixesha lokungasebenzi, kunye neendleko zizonke zobunini (TCO). Xa ukhetha izixhobo zokugquma ezifana neepleyiti zemihlathi, ii-cone liners, ii-blow bars, kunye neengcebiso zehammer, uninzi lwabasebenzi lugxila kakhulu kulwakhiwo lwezinto, njengomgangatho wentsimbi ye-manganese okanye umxholo we-chromium, kodwa ke luyityeshela into ebalulekileyo elawula ukusebenza kokugqibela kwecandelo: unyango lobushushu. Idatha ye-metallurgical yeshishini ibonisa ukuba nokuba kuneefomyula ezifanayo zeekhemikhali, iindawo ezimbini zokugquma zinokuba nomahluko we-50-100% kubomi benkonzo, kuphela ngenxa yokwahluka kwiinkqubo zonyango lobushushu. Kubasebenzi be-crusher, ukuqonda indima yonyango lobushushu akusiyo nje ulwazi lobuchwephesha—sisixhobo esibalulekileyo sokukhetha iindawo zokugquma ezisemgangathweni ophezulu kunye nokuphepha ukusilela okubizayo kwangaphambi kwexesha. Eli nqaku lihlalutya imigaqo ephambili yonyango lobushushu kwiindawo zokugquma ze-crusher, iinkqubo eziqhelekileyo zezinto eziqhelekileyo, kunye nendlela unyango lobushushu oluphuculweyo oluzisa ngayo iingenelo ezibonakalayo zokusebenza.
Kutheni Unyango Lobushushu Lungaxoxiswani Ngeenxalenye Zokunxiba ZeCrusher
Izinto zokuguguleka ezifakwe kwi-as-cast, zisuka ngqo kwi-foundry mold, zinesakhiwo se-metallurgical esingazinzanga, ezinobunzima obungalinganiyo, uxinzelelo lwangaphakathi olushiyekileyo, kunye ne-brittle carbide precipitates ezithintela kakhulu ukusebenza. Unyango lobushushu yinkqubo elawulwayo ye-metallurgical esebenzisa imijikelo echanekileyo yokufudumeza, yokubamba, kunye nokupholisa ukutshintsha isakhiwo sangaphakathi sesinyithi, ukuvula amandla apheleleyo ezinto zayo ze-alloy. Umngeni ophambili kuzo zonke iindawo zokuguguleka kwe-crusher kukulinganisela iipropati ezimbini eziphikisanayo: ukumelana nokuguguleka ukumelana nokusikwa kwilitye eliqinileyo, kunye nokuqina ukumelana nokuqhekeka phantsi kwempembelelo ephezulu. Ngaphandle konyango olufanelekileyo lobushushu, olu lungelelwaniso alunakwenzeka. Umzekelo, i-high-chromium casting inokuba nokumelana nokuguguleka okuhle, kodwa ngaphandle konyango lobushushu oluphuculweyo, iya kuba brittle kakhulu ukumelana nempembelelo ephakathi, ekhokelela ekuqhekekeni okukhulu okanye ukwaphuka phakathi kokusebenza.
Iinkqubo Eziqhelekileyo Zonyango Lobushushu Kwizinto Ezisetyenziswa Kwizinto Ezisetyenziswa Kwizinto Eziqhelekileyo Zokunxiba
Isixhobo ngasinye esingagugiyo sinenkqubo yokunyanga ubushushu eyahlukileyo, eyenzelwe ukwakheka kwamakhemikhali kunye nokusetyenziswa kwayo okucetywayo. Kwizinto ezisunguliweyo zobungcali, ukubambelela ngokungqongqo kwezi nkqubo sisiseko seendawo ezisebenza kakuhle nezihambelanayo.
Okokuqala, ukuqinisa amanzi kwintsimbi ye-austenitic manganese, umgangatho wegolide kwiindawo eziphambili zokutyumza. Iintsimbi zeManganese, kuquka iMn13Cr2 esetyenziswa kakhulu kunye neMn18Cr2 enobunzima obuphezulu, zixhomekeke kwisakhiwo se-austenitic sesigaba esinye ukuze zinike ipropathi yazo yokuqinisa umsebenzi: xa zichatshazelwa yimpembelelo ephezulu, umphezulu uyaqina ukumelana nokukrazuka, ngelixa umbindi uhlala uqinile ukuthintela ukwaphuka. Inkqubo yokuqinisa amanzi ifuna ukufudumeza ukuphoswa ukuya kwi-1050-1100°C echanekileyo, ukuyibamba kolu bushushu ukuze kunyibilikiswe ii-carbides kwi-matrix, emva koko ukuyicima ngokukhawuleza emanzini ukuze ivale isakhiwo se-austenitic. Nokuba ukuphambuka okuncinci, njengokungoneli kwexesha lokubamba okanye ukupholisa kancinci, kuya kubangela ukuba ii-carbide precipitates zakheke, kunciphisa ukuqina kwenxalenye ukuya kuthi ga kwi-70% kwaye kwenze ukuba ithambekele ekuqhekekeni ngequbuliso.
Okwesibini, ukucima nokulungisa isinyithi esimhlophe esine-chromium ephezulu, esifanelekileyo ekutyumzeni okuphezulu, okunempembelelo encinci kwesibini kunye nokutyumza okuphezulu. Ukumelana nokuguguleka okugqwesileyo kwesinyithi esine-chromium ephezulu kuvela kwiinxalenye zayo ze-chromium carbide eqinileyo kunye ne-martensitic matrix. Inkqubo yonyango lobushushu ibandakanya umjikelo wokucima olawulwa ngononophelo ukwenza isakhiwo se-martensitic, kulandele inyathelo lokunciphisa uxinzelelo lwangaphakathi kunye nokunciphisa i-austenite egcinwe yi-brittle. Le nkqubo ilinganisela ubunzima obukhulu bokumelana nokuguguleka kunye nokuqina okwaneleyo ukuthintela ukuqhekeka, okubonelela ubomi benkonzo obude kathathu kunentsimbi eqhelekileyo ye-manganese kwizicelo ze-high-abrasion.
Iingenelo ezibonakalayo zoNyango loBushushu oluLungileyo
Kwabo basebenza nge-crusher, ukutyala imali kwiindawo zokuguguleka ezine-heat treatment elawulwa ngokungqongqo kunika inzuzo enokulinganiselwa ngokwezimali kunye nokusebenza. Yandisa ubomi benkonzo ngama-30-80% xa kuthelekiswa neendawo ezine-heat treatment engaphantsi komgangatho, inciphisa amaxesha okutshintsha kunye neendleko zomsebenzi ezinxulumene nayo. Ikwasusa ixesha lokungasebenzi elingalindelekanga elibangelwa kukwaphuka kweendawo ngequbuliso, ingxaki eqhelekileyo ngezinto ezingaphathwanga kakuhle ngobushushu ezinokubiza amashumi amawaka eedola kwimveliso elahlekileyo ngeyure. Okokugqibela, inciphisa i-TCO iyonke: ngelixa iindawo eziphathwa ngobushushu ezisemgangathweni ophezulu zinokuba neendleko eziphezulu ngaphambili, zibonelela ngobomi benkonzo obude obuphindwe kabini ukuya kwezintathu, zinciphisa iindleko zonyaka zeendawo zokuguguleka ukuya kuthi ga kwi-40%.
