Umbhobho wentsimbi ongenamthungo unomgongxo onqamlezileyo kwaye usetyenziswa ngobungakanani obukhulu njengombhobho wokuthutha ulwelo, njengemibhobho yokuthutha ioli, igesi yendalo, igesi, amanzi kunye nezinto ezithile eziqinileyo.Umbhobho wentsimbi kunye nentsimbi engqukuva kunye nezinye intsimbi eyomeleleyo, xa kuthelekiswa nokugoba okufanayo kunye namandla e-torsion, ubunzima obulula, yintsimbi yezoqoqosho enqamlezileyo, esetyenziswa ngokubanzi ekwenzeni iinxalenye zesakhiwo kunye noomatshini, njengezintonga zokomba ioyile, iishafti zokuqhuba iimoto. , izakhelo zebhayisikile kunye nokwakhiwa kwe-scaffolding yensimbi esetyenziselwa ukwenziwa kweentsimbi zentsimbi yombhobho, inokuphucula ukusetyenziswa kwezinto, ukwenza lula inkqubo yokuvelisa, ukugcina izinto kunye nexesha lokucubungula, sele isetyenziswe ngokubanzi ukwenza umbhobho wensimbi.
Iimpawu zoomatshini
Iimpawu ze-Steel mechanical kukuqinisekisa ukuba i-steel end-use properties (iipropati zomatshini) zezibonakaliso ezibalulekileyo, kuxhomekeke kwimichiza yentsimbi kunye nenkqubo yonyango lokushisa.Kwinqanaba lombhobho wensimbi, ngokweemfuno ezahlukeneyo zokusetyenziswa, cacisa iimpawu zokuxinana (amandla okuqina, amandla okuvelisa okanye isivuno, ukunyusa) kunye nobunzima, izikhombisi zokuqina, kukho iimfuno zomsebenzisi zokusebenza okuphezulu kunye nokushisa okuphantsi, njl.
① Amandla okuqina (σb)
Umzekelo kuxinzelelo, awona mandla aphezulu (Fb) amelana ngexesha lokutsalwa, ahlulwe luxinzelelo (σ) olufunyenwe kwindawo yokuqala yecandelo elinqamlezayo (So) lomfanekiso, owaziwa njengamandla e-tensile (σb), iyunithi N/mm2 (MPa).Imele umthamo omkhulu wezinto zetsimbi ukuxhathisa umonakalo kwingcinezelo.Ifomula yokubala yile
Kuphi: Fb - awona mandla aphezulu agcinwe ngumzekelo xa itsalwa, N (Newton);Ngoko - indawo yokuqala ye-cross-sectional ye-specimen, mm2.
②Inqaku lesivuno (σs)
Ngomcimbi wesivuno sezinto zetsimbi, i-specimen kwinkqubo yokwelula yamandla ayinyuki (ihlala ihleli) inokuqhubeka nokwandisa uxinzelelo, olubizwa ngokuba yi-isivuno point.Ukuba ukuwa kwamandla kwenzeka, kufuneka kwenziwe ulwahlulo phakathi kwamanqaku aphezulu nangaphantsi kwesivuno.Iyunithi yenqaku lesivuno yi-N/mm2 (MPa).
Inqaku eliphezulu lesivuno (σsu): ubuninzi boxinzelelo ngaphambi kokuba i-specimen ivelise kwaye amandla aqale ukuwa;inqanaba lesivuno esisezantsi (σsl): ubuncinci boxinzelelo kwisigaba sokukhupha xa isiphumo sokuqala esidlulayo singathathelwa ngqalelo.
Ifomula yokubala inqaku lesivuno yile: ifomyula: Fs - amandla okuvelisa (ngokuqhubekayo) ngexesha lenkqubo ye-tensile ye-specimen, N (Newton) Ngoko - indawo yokuqala ye-cross-sectional ye-specimen, mm2.
③ Ubude emva kwekhefu (σ)
Kuvavanyo lwe-tensile, ukunyuka kwepesenti kubude bomzekelo emva kokuba itsaliwe ukusuka kuphawu lwawo ukuya kubude bophawu lokuqala kubizwa ngokuba lubude.Ichazwa njengo σ kwi%.Kubalwa njenge: ifomula: L1 - ubude bomzekelo emva kokukhupha uphawu lwayo, mm;L0 – ubude bophawu lokuqala lomzekelo, mm.
④ Izinga lokucutheka kwamaqhezu (ψ)
Kuvavanyo lwe-tensile, ukuncipha okuphezulu kwendawo enqamlezayo yomfanekiso ekunciphiseni kwawo emva kokutsalwa njengepesenti yendawo yokuqala yecandelo elinqamlezayo libizwa ngokuba yi-fractional shrinkage rate.Ichazwa njengo-ψ nge-%.Ifomula yokubala ngolu hlobo lulandelayo
Apho: I-S0 - indawo yokuqala ye-cross-sectional ye-specimen, mm2;I-S1 - indawo encinci ye-cross-sectional kwi-shrinkage emva kokuba i-specimen ikhutshwe, mm2.
⑤ Isalathisi sokuqina
Ikhono lezinto zetsimbi ukuxhathisa ukunyanzeliswa kwento enzima kwindawo, ebizwa ngokuba lukhuni.Ngokuxhomekeke kwindlela yovavanyo kunye nobubanzi besicelo, ubulukhuni bunokwahlulwa bubulukhuni beBrinell, ukuqina kweRockwell, ukuqina kweVickers, ukuqina konxweme, ubulukhuni obuncinci kunye nobunzima obuphezulu bobushushu.Kuba ityhubhu isetyenziswa ngokubanzi ukuba neBrinell, Rockwell, Vickers ubulukhuni abathathu.
I-Shandong Xinjie Metal Materials Co., Ltd. yinkampani yombhobho wentsimbi edibanisa imveliso, ukusetyenzwa kunye nokusebenza, ikakhulu ibandakanyeka kwi: umbhobho wentsimbi ongenamthungo (umbhobho wentsimbi ongqindilili, ophantsi naphakathi ityhubhu yebhoyila, umbhobho wentsimbi yealloyi, umbhobho womzuzu osisikwere. , ityhubhu yebhoyila yoxinzelelo oluphezulu, umbhobho wepetroleum wokuqhekeka, umbhobho wesichumiso wekhemikhali, umbhobho wentsimbi ekhethekileyo), intsimbi engatyiwayo (umbhobho wentsimbi engenamthungo, umbhobho odityanisiweyo wentsimbi, ipleyiti yentsimbi, umbhobho/ipleyiti yentsimbi, intsimbi engqukuva, intsimbi engatyiwayo umbhobho mzuzu square), steel stainless Profile (I-beam, intsimbi angle, intsimbi channel) kunye nezinye iimveliso.
