IiCasting eziKhuselekileyo zeNsimbi yeManganese ephezulu

Izixhobo zokucoca nokutyumza, ezifana nezikrini ezingcangcazelayo kunye nezihluli, zihlala zifaka intsimbi ye-chrome ephezulu kunye ne-manganese ephezulu ekwakheni kwazo ngenxa yokumelana kwazo okuphezulu nokuguguleka kunye nempembelelo. Intsimbi ye-chrome ephezulu, enomxholo wayo ophezulu wekhabhoni, inika ubulukhuni obuhle kunye nokumelana nokukrala, okwenza ukuba ilungele ukuphatha izinto ezinzima nezirhabaxa. Intsimbi ye-manganese ephezulu, eyaziwa ngokuqina kwayo, umsebenzi wayo uyaqina xa itshayiswa, inika ukuqina ngokuchasene neengxolo ezinzima kunye neendawo ezixinezelekileyo. Ezi zinto ziphucula ixesha elide kunye nokusebenza kwezixhobo zokucoca, ziqinisekisa ukucutshungulwa kwezinto ngokufanelekileyo ngelixa zinciphisa isidingo sokugcinwa rhoqo kunye nokutshintshwa kwezinto.

    I-Ductile Iron Screening Shaft yezixhobo zokuhlola izinto ezincinci

    Iishafti zesikrini sentsimbi ezithambileyo zisetyenziswa kakhulu kwizixhobo zokuhlola izinto ezincinci, ezifana nezikrini ezingcangcazelayo, izahluli, kunye nee-serf. Ezi shafti zidlala indima ebalulekileyo ekusebenzeni kwezixhobo ngokubonelela ngenkxaso efunekayo kunye nokujikeleza kwimidiya yesikrini, eyahlula izixhobo ngokusekelwe kubukhulu okanye ezinye iimpawu. Xa kufikwa kwimisebenzi yokuvavanya encinci, ukukhetha izinto ezifanelekileyo zeshafti kubalulekile ukuqinisekisa ukusebenza, ukuqina, kunye nokusebenza kakuhle kweendleko.

    Intsimbi ethambileyo, eyaziwa ngokuba yi-spheroidal graphite iron (SGI), yinto efanelekileyo kwiishafti ezincinci zokuhlola izinto ngenxa yokudibanisa kwayo okuhle kakhulu amandla, ukuqina, kunye nokumelana nokuguguleka. Ngokungafaniyo nentsimbi yendabuko, enokuba buthathaka, intsimbi ethambileyo inokuqina okuphezulu kunye nokumelana nempembelelo, ivumela ukuba imelane noxinzelelo loomatshini oludibana nalo ngexesha lenkqubo yokuvavanya. Oku kuyenza ifaneleke kakuhle kwizicelo apho ishafti kufuneka inyamezele iimpembelelo eziphindaphindiweyo, ukungcangcazela, kunye namandla okujikeleza.

    Enye yezona nzuzo ziphambili ze-ductile iron kukukwazi kwayo ukujongana noxinzelelo oluphezulu lokuxinana nokudinwa, nto leyo eyenza ukuba ithembeke kwiindawo ezifuna ukuhluzwa. Isakhiwo sayo esincinci, esiquka i-graphite ngohlobo lwe-spheroids, sinceda ukuphucula ukumelana kwayo nokwakheka kweentanda kunye nokwanda kwazo. Olu buchule bokufunxa ukutshaqeka kunye nokumelana nokuguquka kwesimo kubalulekile xa kuhluzwa izinto ezincinci, ezikhaphukhaphu ezinokubangela ukungcangcazela okuphezulu.

    Ukongeza, intsimbi ethambileyo inika ukumelana nokuguguleka okuhle, nto leyo ebalulekileyo ekugcineni ixesha elide le-shaft kwinkqubo yokuvavanya. Ukuphumelela kwayo kwiindleko xa kuthelekiswa nezinye ii-alloys ezinamandla aphezulu njengentsimbi kwenza ukuba ibe lukhetho olunomtsalane kubavelisi, ingakumbi kwizicelo apho ukuphathwa kwezinto kukwizinga elincinci. Ngokubanzi, ii-shafts zesikrini sentsimbi ethambileyo zibonelela ngokulinganisela okugqwesileyo kokusebenza, ukuqina, kunye nokusebenza kakuhle kweendleko kwizixhobo zokuvavanya izinto ezincinci, ukuqinisekisa ukucutshungulwa kwezinto ngokufanelekileyo ngelixa kunciphisa iindleko zokugcinwa.

    Izixhobo Ezingagugiyo Zentsimbi EneManganese Eninzi Ezisetyenziswa Kwizixhobo ZokuHlola Ezininzi.

    Izixhobo ezingagugiyo zizinto ezibalulekileyo kwizixhobo zokumba nokuhlola, ezenzelwe ukumelana neemeko ezinzima ezi matshini zisebenza phantsi kwazo. Kwimizi-mveliso efana nemigodi, ukumba imigodi, kunye nokucubungula izinto, izixhobo ezifana nee-crushers, ii-screens, kunye nee-conveyors zijongene nokuchatshazelwa rhoqo yimikhosi erhabaxa nenefuthe eliphezulu. Izinto ezicutshungulwayo zihlala ziquka izinto eziqinileyo, ezibukhali nezirhabaxa, ezinokubangela ukuguguleka ngokukhawuleza kwezixhobo. Ngenxa yoko, izixhobo ezingagugiyo ezifana nee-liners, ii-augers, kunye neepleyiti zibalulekile ekuqinisekiseni ukuba ezi matshini zihlala ixesha elide, zithembekile kwaye zisebenza kakuhle.

    Ii-liners, ezidla ngokwenziwa ngezinto ezifana nentsimbi ye-manganese ephezulu, ii-alloys ze-chrome ephezulu okanye i-polyurethane, zihlala zisetyenziswa kwii-crushers, ii-chutes, kunye nezinye izixhobo ezinzima. Ezi liners zisebenza njengemiqobo yokukhusela, zifunxa impembelelo kunye nokukrazuka okubangelwa kukuhamba kwezinto, zandisa ubomi bezixhobo. Ii-liners zentsimbi ye-chrome ephezulu kunye ne-manganese ephezulu, ngakumbi, zinika ubunzima obukhethekileyo kunye nokumelana nokuguguleka, okwenza ukuba zilungele ukuphatha izinto ezinzima ezifana neentsimbi kunye namatye.

    Ii-Augers, ezisetyenziswa kwimisebenzi yemigodi yokuthutha izinto okanye ukubhola, zihlala zichatshazelwa ziimeko ezirhabaxa ezinokukhokelela ekugugeni ngokukhawuleza. Ii-Augers ezingagugiyo, eziqhele ukwenziwa ngentsimbi eqinileyo okanye ii-alloys ezifana ne-tungsten carbide, zenzelwe ukubonelela ngokuqina kwezi ndawo zinzima. Ukukhethwa kwezinto kuqinisekisa ukuba ii-augers zigcina ukusebenza kwazo nangona kukho ukungqubana okuqhubekayo kunye namandla arhabaxa abadibana nawo, okunciphisa ixesha lokungasebenzi kunye nesidingo sokutshintshwa rhoqo.

    Iipleyiti, kuquka iipleyiti zokuguguleka kunye neepleyiti zokuchaphazeleka, zibaluleke kakhulu kwizixhobo zokwemba nezokuhlola. Ezi pleyiti zihlala zifakelwa kwiindawo zezixhobo eziguguleka kakhulu okanye ezichaphazeleka, njengee-hoppers, ii-feeders, kunye neenkqubo zokuhambisa. Zenziwe ngezinto ezifana nentsimbi ye-AR (enganyangekiyo kukuguguleka), zinceda ekukhuseleni isakhiwo esingaphantsi kwesixhobo ekugugulekeni okugqithisileyo. Iipleyiti ezinganyangekiyo kukuguguleka ziqinisekisa ukuhamba kakuhle kwezinto, zinciphisa ukugcinwa, kwaye ziphucula ubomi bezixhobo ngokubanzi.

    Ngamafutshane, ukusetyenziswa kwezinto ezingagugiyo ezifana nee-liners, ii-augers, kunye neepleyiti kubaluleke kakhulu kumashishini emigodi nokuhlola. Ngokukhetha izixhobo ezifanelekileyo—ezilungelelaniswe neemeko ezithile zokugugiswa komatshini ngamnye—abaqhubi banokuqinisekisa ukusebenza okuphuculweyo, iindleko zokulungisa eziphantsi, kunye nobomi obude bezixhobo. Ezi nxalenye zenzelwe ukuphucula ukusebenza kakuhle kwemisebenzi yemigodi, ukugcina oomatshini besebenza kakuhle, nokuba bekwiindawo ezinzima kakhulu.
