Kev vam meej niaj hnub no nyuaj rau xav txog yam tsis muaj hlau. Ntau hom ntawm cov khoom siv no yuav luag txhua qhov chaw. Ob qho khoom siv hauv tsev zoo tib yam thiab cov cuab yeej siv tau yooj yim yog tsim los ntawm nws. Tab sis qhov zoo tshaj plaws, hlau yog ib qho hlau alloy ntawm hlau thiab carbon, txawm li cas los xij, zoo li cam khwb cia hlau. Thiab lawv tsuas yog qhov txawv ntawm qhov feem pua ntawm C2. Ntawd yog, yog tias cov hlau muaj tsawg dua 2.14% carbon, ces nws yog hlau, thiab yog tias ntau dua, ces nws yog cam khwb cia hlau. Tab sis qhov tseeb, txhua lub hlau muaj ntau yam impurities, xws li silicon, phosphorus, sulfur thiab manganese. Thiab metallurgists, ntxiv rau nws cov ntsiab lus xws li chromium, magnesium, molybdenum, npib tsib xee, tungsten thiab vanadium, hloov cov feem pua ntawm cov ntsiab lus alloying thiab carbon, tsim ntau qib ntawm cov hlau no, uas txawv ntawm lawv cov khoom zoo..
Nyob rau hauv qhov no, lawv yog alloyed thiab carbon. Thiab qhov zoo ntawm carbon steel (tsuas yog hlau thiab carbon) nyob ntawm tus nqi ntawm C2 hauv nws. Ntawd yog, yog tias cov hlau no muaj txog li 0.3% carbon, ces nws yog hu ua mos los yog hlau. Thiab hauv cov khoom hlau, qhov feem pua ntawm cov khoom no yog nyob rau hauv thaj tsam ntawm 0.3-2.14%. Tab sistxhua qib ntawm no alloy muaj nws lub hom phiaj. Yog li, piv txwv li, cov txheej txheem hlau muaj siab plasticity, tsis yog hardened, yog yooj yim forged, welded thiab dov ob qho tib si nyob rau hauv txias thiab kub. Yog li ntawd, cov hlau me me yog cov khoom siv pheej yig rau ntau yam tsis-load-cov kabmob.
Cov qib nyuaj ntawm cov hlau no twb tau siv rau lwm lub hom phiaj. Yog li, piv txwv li, ntau tus neeg uas paub txog kev siv tshuab paub tias GOST steel 45 yog dab tsi. Qhov no alloy muaj 0.45% carbon. Cov hlau no tuaj yeem raug rho tawm haujlwm, txhim kho thiab txiav. Tom qab kev txhim kho, qhov chaw xws li txuas cov pas nrig, crankshafts, flywheels, iav rims, axles, bolts thiab lwm yam zoo sib xws yog tsim los ntawm nws. Nws kuj muaj peev xwm ua kom tawv tawv nrog HDTV. Thiab qhov no ua rau nws muaj peev xwm ua kom muaj zog, ntev thiab khiav shafts los ntawm nws, uas yog, qhov chaw uas yuav tsum muaj qhov siab hardness thiab nce hnav tsis kam nrog qis deformation.
Alloyed chromium steel yog dav siv hauv kev tsim kho tshuab. Qhov no twb yog cov khoom siv rau kev tsim khoom ntawm cov khoom muaj zog uas ua haujlwm nyob rau hauv lub teeb loads. Xws li cov hlau tsis yooj yim rau vuam, nws yuav tsum tau cua sov thiab tom qab kev kho cua sov. Yog li, piv txwv li, shafts, axles, rods, plungers, gearshafts, spindles thiab rings yog tsim los ntawm 40X steel. Nws yog tsim rau ua camshafts, crankshafts, racks, mandrels, bushings, nplhaib iav thiab lwm yam precision qhov chaw.
Tsicorrosion-resistant lossis stainless hlau kuj yog siv dav. Cov no yog cov npe xws li 40 X 13, 30 X 13, 12 X 13 thiab lwm yam. Cov alloys no yog cov khoom siv rau kev tsim cov ntsuas thiab txiav cov cuab yeej, cov khoom siv hauv tsev, koob carburetor, springs thiab lwm yam zoo sib xws uas ua haujlwm nyob rau hauv ib puag ncig corrosive thiab kub txog li 450 degrees. Thiab xws li hlau xws li ШХ15 yog hu ua pob-cov kabmob. Thiab cov plungers, plunger bushings, tso tawm lub rooj zaum thiab lub valve lawv tus kheej, pusher rollers, sprayer lub cev thiab lwm yam yog tsim los ntawm nws, uas yuav tsum muaj siab hardness, tiv taus lub zog thiab hnav tsis kam. Feem ntau, yog tias xav tau, qib steel tuaj yeem xaiv rau txhua lub hom phiaj.
