Isetshenziswa kaningi emaphethelweni acijile amasaha kanye namabhore.Lokhu kunamandla kunemishini yensimbi enekhabhoni ephezulu enolwazi oluningi ebivame ukusetshenziswa kusukela ngeminyaka yawo-1940s njengoba ikwazi ukuphatha amazinga okushisa aphakeme ngaphandle kokuthikameze amandla azo (ukuqina).Lesi sakhiwo sisiza i-HSS ukuthi isike ngokushesha kunensimbi ephezulu ye-carbon, yingakho igama elithi High Speed ​​Steel.Emazingeni okushisa asekamelweni, lapho, ikakhulukazi, ukwelashwa okushisa okuphakanyisiwe, ukubuyekezwa kwe-HSS, ingxenye enkulu, kukhombisa ubulukhuni obuphezulu (ngaphezulu kokuqina kwe-Rockwell 60) nokuphikiswa kwamabala (ngokubanzi okuxhunywe ku-tungsten nokuqukethwe kwe-vanadium okuvame ukusetshenziswa HSS) okuqhathaniswa nekhabhoni evamile kanye nedivayisi kuyalungiswa.

Izinhlelo zokusebenza

Ukusetshenziswa okuyinhloko kokulungiswa kwe-Speed ​​​​High kuyaqhubeka nokuba sekuhlanganisweni kwezinsimbi ezihlukene zokusika: izinsimbi, ompompi, izinqamuli zokucubungula, izingcezu zedivayisi, ama-hobbling (amagiya) abasiki, ama-saha imiphetho ecijile, i-planer, nemiphetho ehlangene, ama-switch bits, nokunye. ., naphezu kweqiniso lokuthi ukusetshenziswa kwezibhakela nokukhahlela ibhakede liyakhula.

Amalungiselelo asheshayo athole i-niche emishinini emihle yezandla lapho ubude bawo obuphakeme obuphakeme obuqinile obuhlangene nokuphikiswa kwamabala aklwebhekile kubenze bafaneleka izinhlelo zokusebenza ezinesivinini esiphansi ezidinga iphoyinti elicijile, njengezingodo, izinsimbi, iziqongo zendiza yezandla, nezindwani zasekhishini. nemimese esongwayo evela eDamaseku.

Imishini yensimbi enesivinini esiphezulu iyona eyaziwa kakhulu ngokusetshenziswa emsebenzini wokwenza izinkuni, njengoba izinga lokukhiqizwa komsebenzi ngale konqenqema liyashesha uma kuqhathaniswa namathuluzi aphathwa ngesandla, ngakho i-HSS inomkhawulo omude kakhulu kunemishini yensimbi ye-carbon ejwayelekile.

Izinhlobo

Amafomu asheshayo ama-amalgam athola izakhiwo zawo enanini lezinsimbi eziyingxubevange ezisetshenziswa ku-carbon steel, ngokuvamile njenge-tungsten ne-molybdenum, noma kusukela ekuhlanganisweni kwakho kokubili, ngezinye izikhathi nezinhlanganisela ezihlukene.Banesikhundla esakhiweni esiyinhlanganisela yezingxenye eziningi i-Fe - C - X lapho u-X ebhekisela ku-chromium, i-tungsten, i-molybdenum, i-vanadium noma i-cobalt.Isigaba sika-X sisetshenziswa ingxenye enkulu ngaphezu kwamaphesenti angu-7, kanye nekhabhoni engaphezu kuka-0.60%.

Amakilasi ohlobo lwe-Tungsten (isb. T1, T15) ohlelweni lwezinombolo oluhlanganisiwe (UNS) anikezwa izinombolo esakhiweni se-T120xx, kuyilapho i-molybdenum (isb. M2, M48) kanye ne-T113xx zimaphakathi nezitayela zomgwaqo.Amanani e-ASTM abonisa izinhlobo eziyi-7 ze-tungsten kanye nezinhlobo eziyi-17 ze-molybdenum.

Ukunwetshwa okungaba ngu-10% we-tungsten ne-molybdenum sekukonke kukhulisa ngendlela ekhiqizayo ubulukhuni nokuqina Kwejubane Eliphezulu kulungiselela futhi kugcine lezo zakhiwo kumazinga okushisa aphezulu adalwa lapho kusikwa izinsimbi.

Ingahlala kanjani iqinile?

Lapho ucabanga ngethuluzi lokusika le-HSS, cabanga ngokushisa.Lapho wenza ukufudumala okuncane (ocingweni), ithuluzi lizodonsa kakhulu.Ephuzwini lapho ushisisa ukwelapha i-HSS uyiyisa ezingeni lokushisa elithile (manje elibizwa nangokuthi ukushisa okuphezulu) isikhathi esichazwe ngaphambilini.Lokhu kunikeza i-HSS ubulukhuni bayo obuqondile, nokho ibuthaka ngokwedlulele.Okulandelayo ithathe izinga lokushisa ukuze "yithukuthelise noma ukuyidweba".Lokhu ngokuvamile kufezwa izikhathi ezingaphezu kwesisodwa.Lokhu kuthwala ubulukhuni lapho ubudinga khona futhi kunikeza ukuqina kwe-HSS (kokubili ubulukhuni namandla kulawulwa yinhlanganisela kundaba).Izinga lokushisa elishisayo akumele lidlulwe ekusebenziseni noma ekucijeni idivayisi noma izoqina (ikhululeke).Lokhu kuzohluka kusuka kokumbalwa okugxilwe kukho (Rc) kuye phansi okugcwele.Lokhu ukucaciswa okuyisisekelo kakhulu kwe-HSS enenzuzo yokufudumala.
