Ngokusho kwemithombo yomkhakha, imakethe yomhlaba wonke ye- ijubane lensimbi (HSS) amathuluzi okusika kulindeleke ukuthi akhule abe ngaphezu kwamadola ayizigidi eziyizinkulungwane eziyizigidi ngo-2020. UJackie Wang-General Manager weShanghai Histar Metal, ubheka ukuthi kungani i-HSS isalokhu iyindlela ethandwayo, izingoma ezahlukahlukene ezitholakalayo nokuthi impahla ikwazi kanjani ukujwayela imboni eshintsha ngokushesha.

Yize kunomncintiswano okhulayo ovela ku-carbide oqinile, i-HSS iyaqhubeka nokuthandwa ngabakhiqizi ngenxa yokuqina kwayo kokugqoka okuqinile nobulukhuni obuhle nezakhiwo zokuqina. Amathuluzi wokusika we-HSS afaneleke kangcono ezindaweni zokukhiqiza ngobuningi lapho impilo yethuluzi, ukwenza izinto ezihlukahlukene, ukukhiqiza kanye nezindleko zamathuluzi kubaluleke kakhulu kumsebenzisi wokugcina. Ngakho-ke isadlala indima enkulu ekusetshenzisweni kahle nangokuthembekile kwemishini eminingi.

Futhi, ukugxila kwamanje kwekhwalithi yomkhiqizo omuhle, ehlangabezana nezidingo zesicelo samakhasimende ngentengo engabizi kakhulu, kukhombisa ukuheha esimeni somnotho samanje somhlaba jikelele.

Ukwesekela isidingo esikhulayo somhlaba wonke se- I-HSS, abakhiqizi bamathuluzi okusika banikele ngezinsizakusebenza ezibanzi kulesi sigaba. Lokhu kufaka ukwanda kokutshalwa kwezimali hhayi nje kuphela ekuthuthukisweni komkhiqizo kodwa nasemisebenzini yocwaningo nentuthuko, okuholele ekutheni amathuluzi e-HSS athembeke ngokwengeziwe ngenani lokwehla kwamaphutha, izindleko zokukhiqiza eziphansi kanye nezikhathi ezimfishane zokuhola. Ukwengezwa kwama-substrates athuthukisiwe, kufaka phakathi i-powder metallurgy nokumbozwa kube nesandla ekuthuthukiseni ukusebenza.

I-Shanghai Histar Metal inikeza ishidi elinejubane eliphezulu, ibha eyindilinga nebha eyisicaba. Lezi zinto zisetshenziselwa ukubhola, okokuphikisa, okokuphinda usebenzise, ​​ompompi nabasiki bemishini.

Ukwakheka kwe-HSS

Ukwakheka okujwayelekile kwe-HSS kufaka i-chromium (4%), i-tungsten (cishe i-6%), i-molybdenum (kufika ku-10%), i-vanadium (cishe i-2%), i-cobalt (kufika ku-9%) ne-carbon (1%). Izinhlobo zebanga elihlukile zincike kumazinga ahlukahlukene wezinto ezingeziwe.

I-Chromium ithuthukisa ikhono lokuqina futhi ivimbela ukukala. I-Tungsten inikeza ukusebenza kahle okukhulu kokusika nokumelana nokushisa, kanye nobulukhuni obuthuthukisiwe namandla okushisa aphezulu. I-Molybdenum - umkhiqizo ovela ekukhiqizeni ithusi ne-tungsten - futhi ithuthukisa ukusebenza kahle kokusika nobulukhuni, kanye nokumelana nokushisa. IVanadium, ekhona kumaminerali amaningi, yakha ama-carbide anzima kakhulu wokumelana nokugqoka okuqinile, ikhuphula ukumelana namandla okushisa nokuqina, kanye nokugcinwa kobulukhuni.

ICobalt ithuthukisa ukumelana nokushisa, ukugcinwa kobulukhuni futhi ithuthukise kancane ukuqhutshwa kokushisa, kuyilapho ikhabhoni, inyusa ukumelana nokugqoka futhi inesibopho sobulukhuni obuyisisekelo (cishe u-62-65 Rc). Ukungezwa kwe-cobalt engaphezulu kwe-5-8% ku-HSS kuthuthukisa amandla nokuqina kokugqoka. Imvamisa, ama-drill enziwe ngokufakwa kwe-cobalt eningi asetshenziswa ekusebenzeni okuqondile kwesicelo.

Izinzuzo

Amathuluzi we-HSS angamelana nokudlidlizela, noma ngabe yiluphi uhlobo lwethuluzi lomshini, noma ngabe ukuqina kulahlekile ngokuhamba kwesikhathi futhi noma ngabe kunjani ukubambeka kocezu lomsebenzi. Kungavimbela ukushaqeka kwemishini ezingeni lamazinyo emisebenzini yokugaya futhi kubhekane nezimo ezihlukile zokuthambisa ezingabangela ushintsho olushushu.

Futhi, ngenxa yamandla we-HSS, abakhiqizi bamathuluzi bangaveza imiphetho yokusika ebukhali ngokwedlulele. Lokhu kwenza kube lula ukwenza imishini ngezinto ezinzima, kunikeza umsebenzi omncane wokwenza lukhuni izinsimbi ezingenantambo ze-austenitic kanye nama-nickel alloys, futhi kunikeza ikhwalithi ephezulu yendawo nokubekezelelana kwezingxenye ezenziwe ngomshini.

Njengoba insimbi igundiwe futhi ingadabuki, inikeza impilo yethuluzi elide ngamazinga okushisa aphansi. Kudinga namandla okusika aphansi, ekugcineni okusho ukusetshenziswa kwamandla amancane kusuka kuthuluzi lomshini. Ngokombono wempilo yamathuluzi, i-HSS isebenza kahle kakhulu ngezinhlelo zokusika ngezikhathi ezithile.

Isifinyezo

Esikhathini lapho abasebenzisi badinga amathuluzi athembekile, angaguquki, enza izinto eziningi ngentengo engabizi, insimbi esheshayo kusengukukhetha okuhle kuzinhlelo eziningi. Ngakho-ke, isengazibamba emakethe ngokulwa nezinto ezincane nezithuthuke kakhulu kwezobuchwepheshe.

Uma kukhona, I-HSS sekuneminyaka eminingi iqina ngokuzivumelanisa nezingubo ezintsha, ukulungisa ukwakheka kwayo nokungeza ubuchwepheshe obusha, konke okusiza ukugcina isikhundla sayo njengezinto ezibalulekile embonini yokusika izinsimbi.

Umkhakha wemboni yamathuluzi wokusika ubulokhu uyindawo yokuncintisana futhi I-HSS ihlala iyinto eyinhloko ekunikezeni amakhasimende lokho obekulokhu kuyimfuno ebalulekile: ukukhetha okuhle.
