● Isishwankathelo sentsimbi yesixhobo esinesantya esiphezulu
Intsimbi ekhawulezayo (i-HSS okanye i-HS) liqela leentsimbi zezixhobo, ezisetyenziswa kakhulu njengezixhobo zokusika.
Iintsimbi ezinesantya esiphezulu (i-HSS) zifumene igama lazo ngenxa yokuba zinokusetyenziswa njengezixhobo zokusika ngesantya esiphezulu kakhulu kunokuba kunokwenzeka ngeentsimbi zezixhobo zekhabhoni. Iintsimbi ezinesantya esiphezulu zisebenza ngesantya sokusika esiphindwe kabini ukuya kathathu ngaphezu kweentsimbi zekhabhoni.
Xa izinto eziqinileyo zicutshungulwa ngesantya esiphezulu kunye nokusika okunzima, ubushushu obaneleyo bunokuphuhliswa ukuze kubangele ubushushu bomphetho wokusika bufikelele kubushushu obubomvu. Olu bushushu buya kuthambisa intsimbi yesixhobo sekhabhoni equlethe nekhabhoni ukuya kuthi ga kwi-1.5 ekhulwini ukuya kwinqanaba lokutshabalalisa amandla azo okusika. Iintsimbi ezithile ezixutywe kakhulu, ezibizwa ngokuba ziintsimbi zesantya esiphezulu, ke ngoko, ziye zaphuhliswa ekufuneka zigcine iimpawu zazo zokusika kumaqondo obushushu afikelela kwi-600°C ukuya kwi-620°C.
● Iimpawu kunye nobubanzi besicelo
Yintsimbi ye-tungsten high carbon vanadium ene-drill. Inokumelana nokuguguleka okuphezulu, ubulukhuni kunye nokumelana nokushisa, kwaye iphucula ubulukhuni obuphezulu kunye nobunzima obomvu. Ukuqina kwayo kuphindwe kabini kunokwentsimbi eqhelekileyo enesantya esiphezulu. Ifanelekile ekuchweni izixhobo ezinzima ukuzifumana kumatshini ezifana nentsimbi enamandla aphakathi, intsimbi eqengqelekayo ebandayo, intsimbi ye-alloy ephosiweyo kunye nentsimbi enamandla aphantsi, kwaye ayifanelekanga ukuvelisa izixhobo ezintsonkothileyo ezichanekileyo. Amandla kunye nokuqina kwale ntsimbi kuphantsi kwaye ixabiso libiza kakhulu.
● Ipropati ye-CPM Rex T15 eqinileyo
(1) Ubulukhuni
Isenokugcina ubulukhuni obuphezulu kubushushu obusebenzayo obumalunga nama-600 ℃. Ubulukhuni obubomvu buyimpawu ebaluleke kakhulu yentsimbi kwiidayisi ezishushu zokuguqulwa kwesakhiwo kunye nezixhobo zokusika ezikhawulezayo.
(2) Ukumelana nokurhawuzelelwa
Iyakwazi ukumelana nokuguguleka, oko kukuthi, iyakwazi ukumelana nokuguguleka. Esi sixhobo sisenokugcina imo kunye nobukhulu baso phantsi kwemeko yokuba sithwele uxinzelelo olukhulu kunye nokungqubana.
(3) Amandla nokuqina
Intsimbi yesixhobo esinesantya esiphezulu esineCobalt isekelwe kwintsimbi yesixhobo esinesantya esiphezulu kwaye inokuphuculwa kakhulu ngokongeza inani elithile le-cobalt
Ukuqina, ukumelana nokuguguleka kunye nokuqina kwentsimbi.
(4) Eminye imisebenzi
Ineempawu ezithile zoomatshini ezinobushushu obuphezulu, ukudinwa kobushushu, ukuqhuba kobushushu, ukumelana nokuguguleka kunye nokugqwala, njl.
● Ukwakheka kweekhemikhali:
I-Si:0.15~0.40 S:≤0.030
P:≤0.030 Cr:3.75~5.00
V:4.50~5.25 Ubude:11.75~13.00
I-Co:4.75~5.25
● Indlela yokunyibilikisa i-CPM Rex T15 solid bar
Indlela yokunyibilikisa isithando sombane okanye indlela yokunyibilikisa i-electroslag kufuneka isetyenziswe xa kunyibilikiswa. Iimfuno zendlela yokunyibilikisa ziya kucaciswa kwisivumelwano. Ukuba ayichazwanga, umthengisi uya kukhetha.
● Iinkcukacha zonyango lobushushu kunye nesakhiwo se-metallographic: iinkcukacha zonyango lobushushu: ukucima, 820~870 ℃ ukufudumeza kwangaphambili, 1220~1240 ℃ (isithando sokuhlambela ityuwa) okanye 1230~1250 ℃ (isithando somlilo sebhokisi) ukufudumeza, ukupholisa ioyile, 530~550 ℃ ukufudumeza amaxesha ama-3, iiyure ezi-2 ngexesha ngalinye.
● Imeko yokuhanjiswa kwe-CPM Rex T15 solid bar
Iibhari zentsimbi mazihanjiswe zikwimeko yokuqhoboshelwa, okanye emva kokuba ziqhoboshelwe kwaye zicutshungulwe ngezinye iindlela zokucubungula, iimfuno ezithile ziya kucaciswa kwisivumelwano.
