Steel - ib tug indispensable khoom

Niaj hnub nimno kev vam meej yog ib qhov nyuaj rau xav txog tej yam tsis muaj lub hlau. Txawv qib ntawm no cov ntaub ntawv uas yog siv zoo nyob qhov twg. Los ntawm nws yog ua raws li zoo tib yam khoom hauv tsev, thiab txoj kev seev. Tab sis tob steel - yog ib tug hlau hlau thiab cov pa roj carbon, txawm li cas los, raws li cov cam khwb cia hlau. Thiab kom paub qhov txawv rau lawv xwb qhov feem pua ntawm C2. Uas yog, yog hais tias tus hlau yog tsawg tshaj li 2,14% carbon, qhov no steel, thiab yog hais tias xav paub ntxiv - nws yog twb muab pov. Tab sis nyob rau hauv qhov tseeb, txhua steel muaj ntau yam impurities xws li silicon, phosphorus, sulfur thiab manganese. Ib tug metallurgical los ntawm kev ntxiv thereto hais xws li chromium, manganese, molybdenum, npib tsib xee, tungsten, thiab vanadium los hloov qhov feem pua ntsiab lus ntawm alloying ntsiab thiab cov pa roj carbon, ua ntau hom ntawm no hlau uas txawv ho nyob rau hauv lawv cov qualities.

Nyob rau hauv no hais txog, lawv yog doped thiab cov pa roj carbon. Thiab qhov zoo tshaj carbon steel (muaj thiaj tau tuaj ntawm cov pa roj carbon thiab hlau) yog nyob rau ntawm tus nqi ntawm cov C2 therein. Uas yog, yog tias nyob rau hauv xws li ib alloy muaj txog li 0.3% carbon, nws yog hu ua ib tug mos mos hlau los yog technical. Ib tug khoom steel feem pua ntawm no lub caij no yog nyob rau hauv ntau 0,3-2,14%. Tab sis txhua txhua tus qib ntawm cov hlau nws muaj nws lub hom phiaj. Piv txwv li, coj mus muag hlau muaj ib tug high ductility, tsis tawv, yooj yim forged, welded thiab kuav los tiag nyob rau hauv lub txias thiab nyob rau hauv lub kub lub xeev. Yog li ntawd, me me steel - ib tug kuj tsis tshua muaj nqi khoom siv rau ntau qhov chaw tsis nqa loads.

Khoom hom ntawm tus hlau tau siv rau lwm yam hom phiaj. Piv txwv li, muaj ntau yam miv technology tus neeg paub dab tsi GOST steel 45. ntawd yog, tus hlau muaj 0,45% carbon. Qhov no steel yog twb tau kalit, thiab txhim kho cov Tshuag tshem tawm cov txheej txheem. Los ntawm nws tom qab kev txhim kho kom yus paub meej li txuas rods, crankshafts, flywheels, ntiv nplhaib zog, shafts, bolts thiab cov zoo li. nws kuj muaj lub peev xwm los nto hardening los ntawm txoj kev loj. Qhov no ua rau nws tau los tsim therefrom zog, ntev thiab tsav tsheb shafts, i.e. qhov chaw uas yuav tsum tau muaj siab nto hardness thiab lub siab coj kuj nyob qis deformation.

Nyob rau hauv engineering siv lug hlau chrome hlau. Qhov no yog cov ntaub ntawv uas rau manufacturing high-zog qhov chaw uas ua hauj lwm thaum uas tsis muaj loadings. Xws li ib tug hlau yog nyuaj yuav tsum tau welded, nws yuav tsum tau cov cua kub thiab tom ntej thermal kho mob. Yog li, piv txwv li, los ntawm steel 40X ua shafts, axles, rods, pistons, pinion shafts, koob thiab rings. Nws yog haum rau qhov siv thiab ua cov cam thiab crankshafts, rods, mandrels, bushings, iav rims thiab lwm yam precision qhov chaw.

Tsis tas li ntawd lug siv thiab corrosion-resistant los yog stainless hlau. Qhov no cim xws li ib tug 40 X 13, 30 X 13, 12 X 13, thiab ntau lwm tus. Cov alloys yog cov khoom rau cov cov tonnage thiab txiav cov cuab yeej, cov neeg hauv tsev cov khoom, carburetor koob, springs thiab lwm yam xws li qhov chaw uas khiav lag luam nyob rau hauv corrosive npuas ntawm kub txog li 450 degrees. Ib tug steel xws li ib lub pob bearing ShKh15 hu. Thiab vim hais tias nws yuav ua rau lub plungers, nqus tes tsho, Saddles txhaj li qub lawv tus kheej thiab lub valve rocker chais, sprayers, thiab lwm tus lub cev qhov chaw uas yuav tsum tau muaj siab hardness, muaj zog thiab hnav kuj muaj kev sib cuag. Nyob rau hauv kev, yog xav steel stamp yuav khaws rau tej hom phiaj.
