Umkhuba wokusebenzisa ukulahla okulahlekile kwegwebu ukukhiqiza amapuleti aphezulu wensimbi

AmaCreshers asetshenziswa kabanzi ezimbonini ezinjengezimayini, metallurgy, imishini, amalahle, izinto zokwakha, kanye nobunjiniyela bamakhemikhali. Ipuleti lokulayini liyingxenye ebalulekile yokugqoka evikelekile ye-crusher, ethela ngokuyinhloko amandla futhi agqoke ngesikhathi senkonzo. Ukusebenza kwayo kanye nempilo yenkonzo kuthinta ngqo ukusebenza kahle kwezimali, impilo yenkonzo, kanye nezindleko zokukhiqiza ze-crusher. Ukumelana nokuvikeleka nokumelana nomthelela kuyizinkomba eziphambili zobuchwepheshe nezomnotho zokulinganisa ipuleti lokulanda. Insimbi ephezulu ye-manganese isetshenziswa kakhulu ekukhiqizweni kwama-crusher liners. I-High Manganese Steel Castings eqiniswa ngokuqina lapho ifakwa emthonjeni noma amabutho aphezulu, ikhulisa kakhulu ubulukhuni bawo, yakha indawo enzima yangaphakathi, futhi isebenza ngokulimala okuhle kakhulu. Bangamelana nemithwalo emikhulu yomthelela ngaphandle komonakalo futhi babe nokumelana okuhle kokugqoka. Ngakho-ke, zivame ukusetshenziswa ekwenziweni kwezitho ezingamelana nokugqokwa.    

Kodwa-ke, insimbi ephezulu ye-manganese ayikwazi ukwenza umsebenzi wokusebenza kanzima ngaphansi kwemibandela yokuthwala umthelela oqinile, okuholele ekutheni ubunzima obungeqile kodwa amandla anganele, kanye nokumelana nemishini ngeke kuhlangatshezwane nezidingo. Ngakho-ke, ukusebenza okuhlosiwe kwe-Alloy Chemical CORCOSIING Design kanye nokwelashwa kokushisa kuyadingeka ukufeza ukusebenza okufunayo. Lolu cwaningo luphenya ukwakheka kwamakhemikhali, ukuncibilika, ukuphonsa, nokushisa ukushisa kwama-alloys ensimbi aphezulu okukhiqiza ama-movie aphezulu wensimbi, ngenkathi kuqinisekiswa ubunzima obuphezulu nobunzima, kanye nokwenza ngcono ukumelana nokugqoka kwe-crusher liners.

Ukwelashwa kwe-Alloying nokuguqulwa kungenye yezindlela eziphambili zokuthuthukisa ukumelana nokugqokwa kwensimbi ephezulu ye-manganese. Ngokungeza izinto ezengeziwe ezifana ne-Cr, SI, MO, v, TI to High Manganese Steel futhi ulishintshe, izinhlayiya ze-carbide ezihlakazekile zingatholakala kwi-matrix yayo ye-aucen. Ukwakheka kwezinhlayiya ze-carbide ngesigaba sesigaba esiqinisa isimo ngokusebenzisa ukwabiwa kanye nokusetshenziswa kwezinto ezenziwayo ukuqinisa i-matrix ye-aucenquite ukuthuthukisa amandla alonakalisayo okuthuthuka akwazi ukwenza insimbi ye-mangen ephezulu. Inhlanganisela efanelekile ye-MN, CR, kanye ne-SI e-High Manganese Steel Lining Plate ithuthukisa ukuqina kwezinto ezibonakalayo, kunciphisa izinga lokushisa lenguquko lafelansite, bese lihlaziya usayizi wokusanhlamvu. Ngaphezu kwalokho, engeza inani elincane le-MO, CU, nezinto zomhlaba ezingandile zomhlaba zekwelashwa kokuguqulwa kwe-microallooling kanye ne-composite yokuguqulwa kuhlanjululwe insimbi encibilikisiwe, ecwengeke ngempumelelo njengesakhiwo se-matrix.

Ukuncibilika kwensimbi ephezulu yemanganese kwenziwa esithandweni sokungeniswa kwe-alkaline medium imvamisa. Ngesikhathi senqubo yokuncibilika, ukushukumisa kwensimbi ebilisiwe kufanele kugwenywe ngangokunokwenzeka ukunciphisa i-oxidation yenkokhiso yocingo. Inqubo yokushintshanisa ifaka izigaba ezifana nesikhathi esincibilikayo, ukulungiswa kwensimbi kanye nokulungiswa kokuqanjwa, ukuwohloka kokugcina, nokwelashwa okuwohloka. Amabhlogo wezinto ezibonakalayo angezwe esigabeni sakamuva sokunyibilika akufanele abe mkhulu kakhulu futhi kufanele omiswe emazingeni okushisa athile. Ukulandelana kokuphakelayo kungukuthi: Scrap Steel, i-Iron Iron → I-Nickel Plate, i-chromium iron, i-molybdenum iron → i-silicon iron, i-manganesen iron three three three fin Ukuvuselelwa kwe-thermal kwe-malindese yensimbi ye-alloy kunqubo yokuphonsa kungukuphela kwe-1 / 5-1 / 4 yalokho kwensimbi yekhabhoni, ngokuvuselelwa okungekho emthethweni, ukuqina kancane, kanye ne-shrinkage enkulu. Kuthambekele ekuqhekekeni okushisayo nokuqhekeka okubandayo ngesikhathi sokuphonsa. I-shrinkage yamahhala ingu-2.4% -3.6%, nge-shrinkage ebanzi eqondile kanye nesilinganiso esiphezulu sokuqina kwe-shrinkage kunensimbi yekhabhoni. Inokuzwela okukhulu kokuqhekeka futhi ithambekele ekuqhekekeni ngesikhathi sokuqina. Kukhethwe ama-foam foam, amamodeli we-foam ahlanganiswe ama-forform amamodeli, izinto zokuzenzakalelayo zixubha futhi zomiswe, kuvinjelwe futhi kuthululwe ngaphansi kwengcindezi engemihle. Ngokuvamile, i-iron yokupholisa yangaphakathi ayinikeziwe, futhi i-iron yokupholisa yangaphandle isetshenziswa emhlanganweni oshisayo ukwenza lula ukuqina okukodwa noma okulandelanayo kwensimbi. Uhlelo lokuthulula lwenzelwe njengohlobo oluvaliwe lwe-semi, nomgijimi oguqukayo otholakala ohlangothini olude kakhulu lwebhokisi elingaphezulu lokuphonsa. Abagijimi abaningi bangaphakathi bamiswa ebhokisini eliphansi, ngokulinganayo basatshalaliswa ekwakhekeni kwecilongo elisicaba. Ukwakheka kwesigaba sesigaba senzelwe ukuba mncane futhi kubanzi ngokwanele ukwenza lula ukwephula kepha hhayi ukuvimbela ukushwabana. Beka ibhokisi lesihlabathi endaweni engu-5-10 ° angle emhlabathini ngesikhathi sokuthulula. Ukuze kube lula kokuhlanza i-riser, kusetshenziswa izibhamu ezifakwayo ngama-blades wokusika. Insimbi ephezulu ye-manganese ine-fluodity enhle kanye nekhono eliqinile lokugcwalisa lapho lithelwa ekushiseni kwe-1500-1540 ℃. Ngesikhathi sokuthulula, landela umgomo wokushisa okushisa okuphansi okusheshayo futhi usebenzise indlela yokusebenza ehamba kancane, esheshayo, nehamba kancane. Ukuphonsa kupholile ebhokisini amahora angama-8-16, futhi ibhokisi livulwa lapho amazinga okushisa ehla ngaphansi kwama-200 ℃. Inqubo yokwelashwa ekushiseni yamukela inqubo yokwelashwa okushisa "yokucisha + yokushisa + esekelwe ekwakhekeni kwamakhemikhali, njengoba i-cast fissstreature, izidingo zokusebenza, kanye nezimo zokusebenza zepuleti lokufaka. Ngemuva kokuhlolwa okuphindaphindiwe, kwatholakala inqubo yokwelashwa okushisa kahle: kancane kancane khulisa amazinga okushisa nge-100 ℃ / h; Gcina cishe u-700 ℃ amahora angu-1-1,5, futhi ulondoloze ku-30-50 ℃ ngaphezulu kwe-AC3 amahora ama-2-4; Ukucima phansi ngaphansi kwezimo zokupholisa zomoya eziphoqelelwe, kupholisa kancane kancane ngaphansi kwe-150 ℃ lapho amazinga okushisa ehla cishe ku-400 ℃; Unolaka olufika ngesikhathi, gcina ngo-250-400 ℃ ngamahora ama-2-4, futhi upholile esithandweni sokushisa kwegumbi. Ukulawulwa okuqinile kokushisa okuqediwe, isikhathi sokubamba isikhathi, kanye nesilinganiso sokupholisa kuyadingeka ngesikhathi sokusebenza, ikakhulukazi isikhathi sokubamba izilinganiso eziphansi ze-baini tekite transformation zone.
