Irakoreshwa kenshi mumbaraga-ibona impande zikarishye na bores.Ibi birakomeye kuruta ibyuma byuburambe bwa karubone byinshi byakoreshejwe kuva 1940 kuko bishobora guhangana nubushyuhe bwo hejuru bitagize ingaruka kumbaraga zabo (gukomera).Uyu mutungo ufasha HSS guca vuba vuba kuruta ibyuma bya karubone, niyo mpamvu ijambo ryihuta ryihuta.Ku bushyuhe bwicyumba, muriyo, igice kinini, cyasabye kuvura ubushyuhe, gusubiramo HSS, kubice byinshi, kwerekana ubukana bwinshi (hejuru yubukomere bwa Rockwell 60) hamwe no gukuraho ibibanza (hamwe na byinshi bihujwe na tungsten na vanadium bikoreshwa kenshi muri HSS) itandukanye kandi isanzwe ya karubone nibikoresho bitegura.

Porogaramu

Ikoreshwa ryibanze ryihuta ryihuta ritegura gukomeza kuba muguteranya ibikoresho bitandukanye byo gutema: imyitozo, kanda, gutunganya ibikoresho, ibikoresho bya hobbling (ibikoresho), kubona impande zikarishye, umuteguro, hamwe nu mpande zombi, guhinduranya bits, nibindi. ., nubwo bwose gukoresha gukubita no gutera indobo biraguka.

Imyiteguro yihuse yasanze icyuho mubikoresho byiza byintoki aho kuramba kwinshi kurwego rwo hejuru hamwe no kurwanywa hejuru yabatandukanije byatumaga bikwiranye na progaramu yihuta ikenera ingingo ityaye, nkibiti, ibiti, hejuru yindege yintoki, hamwe nigikoni cy igikoni. no kuzinga ibyuma biva i Damasiko.

Ibikoresho byihuta byihuta nibyamamare bizwi cyane mugukoresha mubiti, kubera ko urwego rwo gukora umurimo urenze inkombe rwihuta kubikoresho byabigenewe, HSS rero ifite uburebure burebure kuruta ibyuma bisanzwe bya karubone.

Ubwoko

Ihute ryihuse ni amalgams ikura imitungo yabyo mubyuma byinshi bivanga bikoreshwa mubyuma bya karubone, mubisanzwe nka tungsten na molybdenum, cyangwa biva mubihuza byombi, rimwe na rimwe nibintu bitandukanye.Bafite umwanya mubice byinshi bigize ibice Fe - C - X aho X yerekeza kuri chromium, tungsten, molybdenum, vanadium cyangwa cobalt.Icyiciro cya X kirakoreshwa mugice kinini hejuru ya 7 ku ijana, hamwe na karuboni zirenga 0,60%.

Amasomo yo mu bwoko bwa Tungsten (urugero: T1, T15) muri sisitemu ihuriweho na numero (UNS) bahabwa imibare muburyo bwa T120xx, mugihe molybdenum (urugero M2, M48) na T113xx hagati yuburyo bw'imihanda.Indangagaciro za ASTM zerekana uburyo 7 bwa tungsten nuburyo 17 bwa molybdenum.

Kwaguka kwa 10% bya tungsten na molybdenum byongera umusaruro muburyo bukomeye no gukomera kwumuvuduko mwinshi utegura kandi ugakomeza iyo mitungo kubushyuhe bwinshi bwakozwe mugihe cyo gutema ibyuma.

Nigute bishobora kuguma bigoye?

Mugihe utekereje kubikoresho byo gukata HSS, tekereza ubushyuhe.Ubushyuhe buke ukora (mubikoresho), nugushushanya igikoresho kizaramba.Mugihe iyo ushyushye uvura HSS uyijyana mubushyuhe bwihariye (ubungubu na none byitwa ubushyuhe bwinshi) mugihe cyagenwe.Ibi biha HSS gukomera kwayo, nyamara birakomeye cyane.Ibikurikira byafashe ubushyuhe bwo "kurakara cyangwa gushushanya".Mubisanzwe bikorwa inshuro zirenze imwe.Ibi bitwara ubukana aho ubikeneye kandi bigaha HSS gukomera (gukomera nimbaraga bigenzurwa nibintu byose).Ubushyuhe bwo hejuru ntibugomba kurenga mugukoresha cyangwa kubaha igikoresho cyangwa bizakomera (humura).Ibi bizatandukana kubintu bibiri byibandaho (Rc) kugeza byuzuye.Nibisobanuro byibanze byubushyuhe buhemba HSS.
