Isantya steel High. iimpahla zazo kunye nokubekwa

Kule mihla,-high speed yesinyithi iyaqhubeka kuba ukuveliswa nemilomo ezahlukeneyo zesinyithi kunye nezinto phambili isixhobo ahlabayo. aluminiyamu ezinjalo asetyenziswa rhoqo ekwenziweni iisarha ngomatshini, izilumkiso, kunye izilumkiso iintloko zokusebenza. Nangona ukubonakala ngoku iintlobo ezahlukeneyo zonke iintlobo khabhayithi waqinisa nezinto edityanisiweyo yodongwe ukubonelela intsebenzo okukhulu processing, isixhobo-high speed yodidi ngokuqinileyo ukubamba izikhundla zabo.

Ukusetyenziswa kwezi aluminium ezinjalo ekuveliseni izixhobo ezintsonkothileyo-ngokusika ngenxa kwindibaniselwano apho amandla aphezulu (ukuya kwi-68 HRC) kunye nozinzo thermal (bangalahlekelwa iimpawu zazo zomsebenzi maxa wambi amaqondo obushushu 650 ° C) kunye ixabiso eliphezulu viscosity, kude kunene ukuba izibonelelo edityanisiweyo khabhayithi . Ngaphezu koko,-high speed intsimbi na ukuziqhelanisa eziphakamileyo kakhulu, nto leyo ethetha workability elungileyo kunye noxinzelelo inkqubo ahlabayo.

Ziziphi iimpawu ziya kuba intsila onjalo kuxhomekeke kwimiba alloying. Ngokuqhelekileyo,-high speed intsimbi yinkqubo multicomponent equlathe chromium, molybdenum, Tungsten, ayibe, kunye vanadium. Ubukho amacandelo ahlukeneyo, kwakunye isiqulatho wabo ngokwemiqathango ipesenti kubonisiwe kule zokuphawula. Ileta P apha kuthetha ukuba sobhedu ngesantya esiphezulu, inombolo elandelayo ibonisa isiqulatho Tungsten kwi pesenti. oonobumba Eminye ukuchaza ukuba ubukho kwezinye izinto alloying, kwaye amanani esiza emva kokuba iileta - ipesenti yabo ubunzima iqhezu kwi ingxubevange. Ngoko ke, incwadi M ibonisa ubukho molybdenum kule nkqubo, F - vanadium K - ayibe, A - nitrogen.

Ngokutsho umxholo ngesantya dopants zentsimbi zingahlulwa zibe Tungsten, molybdenum, Tungsten kunye molybdenum. Iqela ekhethekileyo eyabelwe iintsimbi exutyiweyo kunye ayibe. aluminiyamu enjalo ngokuqhelekileyo ezisetyenziswayo xa kwenziwa imveliso lwezixhobo machining iindawo ezinzima superalloys. High speed steel, ingxubevange vanadium kakhulu yenzelwe ukuvelisa izixhobo ekuthiwa-njalo "nokuyifeza" kugudiswa - broaches, reamers kunye nezinye.

Eqhelekileyo kakhulu kwaye mhlawumbi uhlobo zindala P18 ensimbi-high speed isetyenziselwa ukwenziwa emise nezintsonkothileyo izixhobo lwelizwe. Zibhekisa ifomu umgangatho ophezulu processing umgangatho ngentsimbi zenziwa becala of ikhasi 9 brand ingxubevange. Ukusuka nayo ematyeni, abaxholi ezinjengezo.

Ngokusebenza lobushushu yodidi isantya egqiba zahlulwe ngokweendidi ezintathu: aluminium kunye nokumelana nobushushu yesiqhelo, phezulu, kwaye phezulu. Kwiqela lokuqala ngamalungu Tungsten (R18, R9) kunye Tungsten-molybdenum (R6M5). La manqaku asetyenziswa xa kusenziwa zesinyithi non-ayoni, yodidi noshowo uphose yentsimbi.

Ngokuba izinto ze kudidi lwesibini iphawulwa ezinomthamo eliphezulu kakhulu ayibe, vanadium kunye carbon. I brand ethandwa kwiqela - R6M5F3. Vanadium steel ebonakala ukuxhathisa eliphezulu banxibe. ethile obunzulu kuphela - embi sanding, ngenxa yokuqaqadeka carbides vanadium ayikho ngaphantsi Isalathisi efanayo elektrokorundovogo ukugaywa ivili.

Ekugqibeleni, lo kudidi lwesithathu ngentsimbi esibonakala ipesenti esezantsi umxholo carbon, nto leyo ifanele unyango ubushushu-resistant, intsimbi engatyiwa titanium aluminium. Enye inkalo uphawu kubo - inani elikhulu lweziqalelo alloying. Kweli qela ziquka iintlobo ezifana 3V20K20H4F, V11M7K23 et al.
