Xa usiva 'amalungu angagugiyo', abantu abaninzi bacinga ngokukhawuleza ngobulukhuni. Rockwell lo, Brinell ukuba. Linani lokuqala elicelwa ngumntu wonke, kwaye ngokunyaniseka, sisiqalo esifanelekileyo. Kodwa ukuba ubukulo mdlalo ixesha elide ngokwaneleyo, uyazi ukuba kulapho incoko yokwenyani iqala khona, ayipheli. Ndibone iiprojekthi ezininzi kakhulu zivaliwe ngenxa yokuba umntu wayalela inxalenye esekelwe kuphela kumlinganiselo wobunzima obuvela kwikhathalogu, kuphela ukuba yasilela kwimiba yeeveki. Inyaniso kukuba, ukunxiba akulotshaba olunye; yindibaniselwano yokukrazuka, impembelelo, ukuncamathela, kunye nokukhula rhoqo, zonke zidanisa kunye kwindawo erhabaxa. Ukuyiphatha njengengxaki enecala elinye yeyona mpazamo inkulu, kwaye ibiza kakhulu, onokuyenza.
IMaze yeMaterial: Ayinakuze imalunga nentsimbi nje
Ngoko ufuna into enzima. Ingqondo yakho yokuqala inokuba kukuya kwintsimbi ephezulu yechromium okanye isixhobo sentsimbi. Ukukhetha okulungileyo, kwizicelo ezithile. Kodwa masithi ujongene ne-slurry pump impeller. Unezinto eziqinileyo zesantya esiphezulu ezikhuhla umphezulu, kodwa zinokubakho nokuba sesichengeni sekloridi. Intsimbi enzima kakhulu inokuqhekeka phantsi kwe-cavitation, okanye i-corrode kwimida yengqolowa. Apha kulapho incoko ye-alloy iba nzulu. Sibe nempumelelo, kunye nokusilela, okusiqhubele kwizisombululo ezilungiselelwe ngakumbi.
Ndikhumbula iprojekthi yomzi-mveliso wesamente, udibaniso lweblade yefeni ejongene nokugruzuka okugqithisileyo luthuli lokutya okukrwada. Sizame ipleyiti yokunxiba ye-NM400 eqhelekileyo. Kunzima njengezikhonkwane, kodwa ukungcangcazela kunye neempembelelo ezincinci ezivela kwiincinci ezinkulu zikhokelela ekudinweni kweentanda kwiindawo zokunyuka. Ubunzima beza ngeendleko zokuqina. Yayilixesha lokufunda elo. Sitshintshele kubunzima obuphantsi kodwa intsimbi ephezulu yokuqina kunye nokuhanjiswa kwe-carbide eguqulweyo kwi-microstructure. Yayinxiba ngokulungeleleneyo kwaye ayizange iqhekeke. Iindleko zomjikelo wobomi behle kakhulu, nangona i-spec yemathiriyeli yokuqala ibonakala ithambile ephepheni.
Kungenxa yoko le nto iinkampani eziyiqonda ngokwenene le nto, njenge Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), musa ukuthengisa izinto nje kuphela; kufuneka baqonde indlela yokusilela. Ngemvelaphi yabo kwi iqokobhe ngundo ukuphosa kwaye utyalo mali, banokudlala nge-metallurgy ukusuka kwimeko yolwelo. Linqanaba elahlukileyo lolawulo xa kuthelekiswa nokwenza nje isitokhwe sebha. Kuba iindawo ezingagugiyo, inkqubo yokuphosa ngokwayo ivumela ukudala iijiyometri ezintsonkothileyo, kufutshane ne-net-shape ekunzima ukuzisebenzisa kumatshini, kwaye unokuyila iimpawu zokunxiba kwilaphu lenxalenye-efana nokubeka ialloyi ezixhathisayo ezixhathisayo kanye apho kwenzeka khona i-abrasion.
Inkqubo yiNxalenye yoMsebenzi
Ukuthetha ngenkqubo, lo ngomnye umaleko odla ngokungahoywa. Unokuba nokwakheka kwe-alloyi egqibeleleyo, kodwa ukuba unyango lobushushu lucimile, okanye ukuphosa kuphole kakubi, ushiywe nenxalenye eshwabeneyo, enoxinzelelo lwangaphakathi, okanye iipropathi ezingangqinelaniyo. Ndibone iindawo ezidibana nalo lonke uhlalutyo lweekhemikhali zisilela kwangaphambi kwexesha ngenxa yokuba ukucima emva kokuphoswa kwakunobundlongondlongo kakhulu, kudala iintanda ezincinci.
CNC Machining ingena apha, kodwa ngumdaniso oethe-ethe. Machining a lukhuni ukunxiba-resistant inxalenye akufani nokwenza intsimbi ethambileyo. Ujongene nezinto ezizilwelayo. Ukunxitywa kwesixhobo kuyaphambana, kwaye ukuba uvelisa ubushushu obuninzi kakhulu, unokuwuvala umphezulu umaleko owusebenze nzima ukuwenza, wenze ulusu oluthambileyo oluguga ngokukhawuleza. Isakhono sisekwazini ulandelelwano: ngamanye amaxesha umatshini phambi kokuba ubushushu bokugqibela buphathwe, ngamanye amaxesha emva koko, kunye neendlela zesixhobo kunye nokutya kufuneka uhloniphe ubume bezinto. Ivenkile eyenza kuphela i-machining elula ayiyi kuba noseto okanye ukwazi oku. Yiseti yesakhono esikhethekileyo, esidibanisa necala elisisiseko lezinto.
Olu manyano lungundoqo. Inkampani ephethe zombini ukuphosa kunye nomatshini phantsi kophahla olunye, njenge-QSY (uyakwazi ukubona indlela yabo https://www.tsingtaocnc.com), inenzuzo. Bangenza isigqibo kwangethuba: Kule liner yokutyumza, siya kuyiphosa kwi-95% ye-net shape kule ntsimbi ye-manganese ephezulu, emva koko umatshini wokudibanisa ujongano lokunqanda ukubeka esichengeni isakhiwo somphezulu owenziwe lukhuni. Olo hlobo lokucinga lokuhamba kwenkqubo lugcina iindleko kwaye lugcina ukusebenza. Ayilonyathelo lokuvelisa nje; luyilo-lokwenza kunye noyilo-lomsebenzi wesigqibo.
Xa ii-Alloys eziKhethekileyo zingeyonto nje yokunethezeka
Ngoku, kwintsimi engaqhelekanga: i-cobalt kunye ne-nickel-based alloys. Ithegi yexabiso yenza abantu batyhafe. Awuzichazi ezi ngokuzonwabisa. Kodwa kwindawo apho ukunxitywa kobushushu obuphezulu budibana nomhlwa-cinga izihlalo zevalvu kwi-petrochemical cracker okanye iiblade ze-turbine kwindlela yegesi eshushu-ayiyonto yokuphucula; bakuphela kwento eya kusebenza. Ukunxiba apha kudla ngokuba yi-oxidation kunye ne-sulfidation kwi-800 ° C +, idibaniswe namasuntswana e-erosive.
Sivavanye inxalenye yensimbi engenasici kwi-high-temperature ash-handing system. Kwakubonakala kukuhle ngosuku lokuqala. Kwisithuba senyanga, umphezulu wawune-oxidized kwaye uchithekile, kwaye izinto ezingaphantsi zazikhutshwa ngokukhawuleza. Sitshintshele kwi-alloy esekwe kwi-nickel enomxholo ophezulu wechromium. Isantya sokunxitywa siye sacotha ukuya ekurhubuluzeni kuba ingxubevange yenze umaleko ozinzileyo, oncamatheleyo weoksidi okhusela isubstrate. Le nxalenye yayinxiba ngokucotha ngokucothayo lo maleko ize iwulungise, kungekhona ngokulahleka kwezinto eziphathekayo okuyintlekele. Leyo yifilosofi eyahlukileyo yokumelana nokunxiba ngokupheleleyo.
Apha kulapho amava Foundry kunye ialloys ezikhethekileyo ibalulekile. Ukuphosa ezi mathiriyeli lirhamncwa elahlukileyo. Zinokuncipha okwahlukileyo, ukuguquguquka okwahlukileyo, kwaye zisebenza ngamandla ukuba umoya okwiziko awulawulwa. I-Foundry ethi ewe, singayenza loo nto ngaphandle kwerekhodi leflegi ebomvu. Ufuna ubungqina, njengembali yokuvelisa iindawo ezisebenzayo eziye zasinda kwintsimi. Akunjalo malunga nokugalela isinyithi; imalunga nokulawula ikhemikhali entsonkothileyo ngendlela emangalisayo kunye nentshukumo yomzimba ukuze ivelise ubume be microstructure.
IFit kunye noMongo
Nantsi intloko ephathekayo engazange iyenze incwadana: ifanele kwaye ifake. Ungayila ezona zibalaseleyo zehlabathi ukunxiba-resistant i-liner, kodwa ukuba imingxuma yokuxhoma ivaliwe ngesiqingatha semilimitha, okanye ukuba inxalenye ijika kancinane ngexesha lonyango lobushushu, i-fitter kwisiza kuya kufuneka igaye ukuze ilingane. Uyasila kwaloo ndawo uhlawule ngayo intlawulo yenyanga. Ndiyibonile isenzeka. Inkcazo yokunyamezela inxalenye enxitywayo ayingomsebenzi nje; imalunga nokufakelwa. Ngamanye amaxesha kufuneka uchaze imiphezulu efana ne-cast-cast kwiindawo ezingabalulekanga kunye neendawo ezinomatshini kuphela apho ukukhwelana kwenzeka khona. Ngunxantathu wexabiso-ukusebenza-ufakelo.
Enye ingongoma yomxholo: imathiriyeli yokukhwelana. Ukuxhathisa kwelungu akunantsingiselo xa uwedwa. Yinkqubo. I-chute liner eqina kakhulu eyenziwe ngeceramic inokuba mnandi ngokuchasene nesanti yesilica, kodwa ukuba ihlala ibethwa ngehamile yentsimbi yemanganese, unokufumana ukuqhekeka okuyingozi. Ngamanye amaxesha, udinga imathiriyeli ethambileyo, yedini ngakumbi kwindawo enye yenkqubo ukukhusela eyona nto ibaluleke kakhulu, icandelo elibiza kakhulu ezantsi komsinga. Imalunga nokulawula indlela yokunxiba kuyo yonke inkqubo, hayi nje ukuthenga eyona nto inzima kulo lonke icandelo.
Oku kucinga kwenkqubo kuko okwahlula umthengisi wamacandelo kwiqabane lezisombululo. Ifuna ukubuza imibuzo emininzi ngaphambili: Yintoni enxibe ngokuchasene nayo? Lithini iqondo lobushushu? Ngaba kukho ukuvezwa kweekhemikhali? Ithini i-angle yempembelelo? Ifakwe njani? Ngowuphi umjikelo wobomi olindelekileyo? Iimpendulo zikhokela yonke into ukusuka ekukhethweni kwezinto ukuya kwindlela yokuphosa ukuya kwi-post-processing.
Ukujonga ngasemva ukuqhubela phambili
Emva kweminyaka engamashumi amathathu, ubona iipateni. Iinkampani ezihlala kule ntsimi, njenge-QSY kunye neminyaka engama-30, azisindi nje ngexabiso. Bakhe indawo yokugcina uhlalutyo lokusilela kunye namabali empumelelo. Baye bafunda, amaxesha amaninzi ngendlela enzima, ukuba a ukunxiba-resistant inxalenye sisithembiso sokuphela kwexesha. Asiyonto yorhwebo. Ixabiso alikho kwikhilogram yentsimbi; ikwiiyure zokusebenza eyinikezelayo phambi kokuba ifune ukutshintshwa.
Ikamva, ndiyacinga, lilele ngakumbi ekudityanisweni koyilo, inzululwazi yezinto eziphathekayo, kunye nolawulo lwenkqubo. Mhlawumbi lulinganiso oluntsonkothileyo lweepatheni zokunxiba ngexesha lesigaba soyilo, okanye uvavanyo olungonakalisi oluqhubela phambili lokuqinisekisa ukuvakala kwesandi sangaphakathi kwiindawo eziphothiweyo ezintsonkothileyo. Injongo ihlala ifana: ukufanisa izinto ezifanelekileyo, ezibunjiweyo kunye nokuphathwa ngendlela efanelekileyo, kwisethi ecacileyo kakhulu yamandla awonakalisayo. Yiphazili engapheliyo, kodwa yiloo nto eyenza ukuba isebenze ngokwenene. Asinto nje malunga nobulukhuni. Nabani na okuxelela ngenye indlela mhlawumbi khange achithe ixesha elaneleyo kumgangatho wesondlo, ejonge indawo engaphumeleliyo kwaye ecinga ukuba uza kuzama ntoni ngokulandelayo.
