Ukusika insimbi ye-manganese iletha izinselele eziyingqayizivele ngenxa yokuqina kwayo okungavamile nokumelana nokuguga. Le nto, evame ukusetshenziswa ezinhlelweni ezifana ne-crusher rotors kanyeinsimbi ye-alloyizingxenye, imelana nemithelela enzima kanye nezimo ezilimazayo. Ucwaningo luveza ukuthi inhlanganisela ye-TiC ye-hierarchical idlula insimbi ye-matrix, inciphisa izinga lokuguga ngaphezu kuka-43% kuyilapho ithuthukisa ukuqina komthelela cishe ngokuphindwe kayisishiyagalolunye.
Okuthathwayo Okubalulekile
- Khethaamathuluzi anamathiphu e-carbidenoma idayimane enamathela ukusika insimbi manganese. Lawa mathuluzi ahlala isikhathi eside futhi asikwe ngokunembile ukuze uthole imiphumela engcono.
- Shisisa insimbi yemanganese ibe ngu-300°C-420°C ngaphambi kokusika. Lokhu kuthambisa insimbi, kwenze kube lula ukusika futhi kusiza amathuluzi ukuthi ahlale isikhathi eside.
- Sebenzisa izinto ezipholile kanye nezinto zokugcoba ukulawula ukushisa nokungqubuzana. Izindlela ezifana nokusebenzisa amanani amancane okuthambisa noma ukupholisa okubanda kakhulu zithuthukisa ukusika kakhulu.
Ukuqonda Izinselele Zokusika Insimbi YeManganese
Izakhiwo Zensimbi YeManganese Ezithinta Ukusika
Insimbi yeManganese, eyaziwa nangokuthi i-Hadfield steel, idume ngokuqina kwayo okungavamile kanye nokumelana nokugqokwa. Lezi zakhiwo ziyenza ilungele izinhlelo zokusebenza ezinzima kodwa futhi idala izinselelo ezibalulekile ngesikhathi sokusika. Okuqukethwe okuphezulu kwe-manganese kokubalulekile kunomthelela ekuziphatheni kwayo okuhlukile ngaphansi kwengcindezi. Ngokwesibonelo:
- Ukusebenza nzima Umphumela: Insimbi yeManganese iba lukhuni ngokushesha lapho ingaphansi komthelela noma ingcindezi. Lesi sakhiwo, nakuba sinenzuzo ukuqina, senza ukusika kube nzima njengoba impahla iba nzima ngesikhathi senqubo.
- I-Dynamic Martensitic Transformation: I-austenite egciniwe kunsimbi ye-manganese ishintsha ibe i-martensite ngesikhathi sokusika. Lokhu kubangela ukwakheka kongqimba oluqinile noluphukayo, okwandisa ukugqoka kwamathuluzi futhi kunciphise izinga eliphezulu.
- Ukuzwela Kokuqamba: Amazinga amaningi ekhabhoni kanye ne-manganese angaholela e-embrittlement, kube nzima inqubo yokusika ngokuqhubekayo. Ukwengeza, i-manganese ihlangana nesibabule ukwenza i-manganese sulfide (MnS), engasiza noma ivimbele ukusebenza ngendlela encike ekugxilweni kwayo.
Ucwaningo lwakamuva lugqamisa ubunkimbinkimbi bokwakheka kwensimbi ye-manganese. Isibonelo, i-manganese ithuthukisa ukungena kwekhabhoni ngesikhathi sokungcwatshwa kwe-carburizing, kodwa ukuvuvuka kwayo ngesikhathi sokuncibilika kuholela esilinganisweni sokulahleka esingu-5-25%. Lokhu akuthinti nje izinga lensimbi kuphela kodwa futhi kubangela izingozi zokuphepha ngesikhathi sokukhiqiza.
Izinkinga Ezivamile Ezibhekana Nazo Ngesikhathi Senqubo Yokusika
Ukusika insimbi ye-manganese kuveza izinselele ezimbalwa ezidinga ukucatshangelwa ngokucophelela. Lezi zindaba zivame ukuvela ezimpahleni zemvelo zezinto kanye nezimfuno ze-ukusika inqubo.
| Inselele | Incazelo |
|---|---|
| Ukusheshisa ukusebenza kanzima | Izinto ezisetshenziswayo ziba lukhuni ngokushesha lapho zithintana, okuholela ekwandeni kokuguga kwamathuluzi nokungalungi kobukhulu. |
| Ukugqoka Kwamathuluzi Okukhulisiwe | Amathuluzi endabuko aba buthuntu ngokushesha, abangela isikhathi esibizayo futhi adinga ukushintshwa njalo. |
| Ubunzima bokunemba kobukhulu | Ukuqina kuholela ekungalungini kahle, okudinga ukuhlolwa njalo ngesikhathi somshini. |

| Ukulawula I-chip Enzima | Ama-chips amade, aqhubekayo angahlanganisa futhi alimaze izinto zokusebenza, okuholela ezingozini zokuphepha kanye nesikhathi sokuphumula. |
| Isikhathi Esikhulisiwe Somashini Nezindleko | Ukwenza imishini kuthatha isikhathi eside ngenxa yokuguga kwamathuluzi kanye namazinga okuphakela ahamba kancane, okuphakamisa kakhulu izindleko. |
Idatha yezibalo iphinde ibonise ubukhali balezi zinselele. Isibonelo, umthelela wendiza esikayo ekusabalaliseni ukuqhekeka kungaholela ekungaqinisekini okuhlobene okungama-27%, uma kuqhathaniswa no-8% endizeni ekhethiwe. Lokhu kuhlukahluka kunomthelela ekuthathweni kwezinqumo futhi kugqamisa ukubaluleka kwamasu okusika anembayo.
Ngokuqonda lezi zinselele, ochwepheshe bangalungiselela kangcono ubunzima bokusika insimbi ye-manganese bese bekhethaamathuluzi afanelekanye nezindlela zokunciphisa lezi zinkinga.
Amasu Ochwepheshe Wokusika Insimbi YeManganese
Ukukhetha Amathuluzi Afanele Womsebenzi
Ukukhetha i-amathuluzi alungilekubalulekile ukusika insimbi ye-manganese ngempumelelo. Ochwepheshe bavame ukuthembela kumathuluzi anesihloko se-carbide ngenxa yekhono labo lokumelana nezinto eziqinisa umsebenzi. Amathuluzi ensimbi yesivinini esikhulu (i-HSS), ngenkathi ebiza kakhulu, avame ukuguga ngokushesha lapho esika insimbi ye-manganese. Amathuluzi e-Tungsten carbide anikeza ukuqina okungcono nokunemba, okuwenza abe yinketho ekhethwayo yokwenza le nto enzima.
Ngokusebenza kwesilinganiso esikhulu, amathuluzi ambozwe ngedayimane ahlinzeka ngokumelana nokugqokwa okukhethekile nokusebenza kokusika. Lawa mathuluzi anciphisa ukuguga kwamathuluzi futhi athuthukise ukuqedwa kwendawo, ikakhulukazi uma usebenza nezingqimba eziqinile ezakhiwe ngesikhathi sokusika. Ukwengeza, ukukhetha amathuluzi anama-engeli e-rake athuthukisiwe nama-chip breaker kungathuthukisa ukulawulwa kwe-chip futhi kunciphise isikhathi somshini.
Izivinini zokusika ezinconyiwe namapharamitha
Isivinini esifanelekile sokusika kanye namapharamitha adlala indima ebalulekile ekuzuzeni imiphumela ephumelelayo lapho kucutshungulwa insimbi ye-manganese. Ucwaningo lokuhlola luphakamisa ukuthi izinga lokuphakelayo elingu-0.008 amayintshi ngokuphenduka ngakunye, isivinini sokusika esingamafidi angu-150 ngomzuzu, kanye nokujula kokusika okungu-0.08 amayintshi kunikeza imiphumela emihle. Le mingcele ihambisana nemihlahlandlela ye-ISO 3685 nezincomo ezivela kubakhiqizi bamathuluzi.
Ukugcina lezi zilungiselelo kunciphisa ukuguga kwamathuluzi futhi kuqinisekisa ukunemba kobukhulu. Isivinini sokusika esinensayo sinciphisa ukukhiqizwa kokushisa, kuvimbela ukuwohloka kwamathuluzi nezinto zokusebenza. Izinga lokuphakelayo elingaguquki lisiza ukulawula ukwakheka kwe-chip, kwehlise ubungozi bokugxamalaza nokulimala. Ama-opharetha kufanele aqaphe la mapharamitha eduze ukuze avumelane nokuhlukahluka kokuqina kwempahla okubangelwa ukuqina komsebenzi.
Izindlela Ezithuthukisiwe: I-Plasma, i-Laser, ne-EDM Cutting
Izindlela zokusika ezithuthukile zinikeza izixazululo ezintsha zokucubungula insimbi ye-manganese.

Le ndlela ilungele izingxenye eziwugqinsi futhi inikeza isivinini sokusika ngokushesha ngokugqoka kwamathuluzi okuncane.
Ukusika nge-laser kunikeza ukunemba nokuguquguquka, ikakhulukazi imiklamo eyinkimbinkimbi. I-laser beam egxilile inciphisa izindawo ezithinteke ukushisa, iqinisekise ukuphela okuhlanzekile. Kodwa-ke, ukusika kwe-laser kungase kube nzima nezingxenye zensimbi ye-manganese eqinile ngenxa ye-thermal conductivity ephezulu.
I-Electrical Discharge Machining (EDM) enye indlela esebenzayo yokusika insimbi ye-manganese. I-EDM isebenzisa izinhlansi zikagesi ukuze igugule impahla, iyenze ifanele ukubunjwa okuyinkimbinkimbi nezendlalelo eziqinile. Le ndlela iqeda ukucindezeleka kwemishini kumathuluzi, ukunciphisa ukugqoka nokuthuthukisa ukunemba.
Indlela ngayinye ethuthukisiwe inezinzuzo zayo, futhi ukukhetha kuncike ezidingweni ezithile zephrojekthi. Ukusika i-Plasma kuhamba kahle ngesivinini, ukusika i-laser ngokunemba, kanye ne-EDM ekusingatheni amajiyometri ayinselele.
Amathiphu Awusizo Wokusika Insimbi YeManganese
Ukulungiselela Impahla Yokusika
Ukulungiselela kahle kuqinisekisa ukusika okuphumelelayo futhi kunciphisa umonakalo wezinto ezibonakalayo. Ukushisa kuqala insimbi yemanganese emazingeni okushisa aphakathi kuka-300°C no-420°C kunciphisa ubulukhuni bayo okwesikhashana. Lesi sinyathelo senza okokusebenza kube lula umshini futhi sandise impilo yamathuluzi. Ukusebenzisa amathuluzi e-carbide noma ensimbi enesivinini esikhulu (HSS) nakho kubalulekile. Lawa mathuluzi amelana nokugqoka futhi anciphisa ingozi yokuqina komsebenzi ngesikhathi sokusika.
Ukupholisa nokugcoba kudlala indima ebalulekile ekulungiseleleni. Ukufaka izinto ezipholile kuqeda ukushisa, kuyilapho izinto zokugcoba zinciphisa ukungqubuzana. Ngokubambisana, zivimbela ukushisa ngokweqile futhi zithuthukise ukusebenza kahle kokusika. Ukuthuthukisa amapharamitha womshini, njengamazinga okuphakelayo kanye nesivinini sokusika, kunciphisa futhi ukuqina komsebenzi. Amasu afana nendlela ye-Taguchi asiza ukukhomba izilungiselelo ezingcono kakhulu zamaphrojekthi athile.
