Raws li kev ua tau zoo thiab kev siv cov xwm txheej, nws tuaj yeem muab faib ua cov hlau zoo tib yam caij nplooj ntoos hlav steel thiab tshwj xeeb alloy caij nplooj ntoos hlav steel. Lub caij nplooj ntoos hlav steel muaj kev ua tau zoo tshaj plaws, nrog rau kev ua tau zoo ntawm metallurgical zoo (siab purity thiab uniformity), zoo deg zoo (kev tswj nruj ntawm deg tsis xws luag thiab decarburization), thiab meej cov duab thiab loj.
Lub caij nplooj ntoos hlav steel yog hais txog cov hlau tshwj xeeb siv rau kev tsim cov springs thiab elastic Cheebtsam vim nws elasticity nyob rau hauv quenched thiab tempered xeev. Lub elasticity ntawm cov hlau yog nyob ntawm nws lub peev xwm los ua kom elastic deformation, uas ua rau nws tuaj yeem tiv taus ib qho kev thauj khoom hauv ib qho kev teev tseg yam tsis muaj deformation mus tas li tom qab tshem tawm cov load. Lub caij nplooj ntoos hlav steel yuav tsum muaj cov khoom zoo heev, xws li cov khoom siv kho tshuab (tshwj xeeb tshaj yog elastic txwv, lub zog txwv, yield ratio), los tiv thaiv elastic txo kev ua tau zoo (piv txwv li los tiv thaiv elastic txo kev ua tau zoo, tseem hu ua kev tiv thaiv kev ua haujlwm), qaug zog kev ua haujlwm, hardenability, lub cev thiab Cov khoom siv tshuaj lom neeg (kub tsis kam, kub tsis kam, oxidation tsis kam, corrosion kuj, thiab lwm yam). Txhawm rau ua kom tau raws li cov kev xav tau saum toj no, lub caij nplooj ntoos hlav steel muaj qhov zoo ntawm cov khoom siv hlau zoo (siab purity thiab uniformity), zoo deg zoo (kev tswj nruj ntawm qhov tsis xws luag thiab decarburization), thiab cov duab thiab qhov loj me.
Kev faib tawm
Carbon caij nplooj ntoos hlav steel
Cov ntsiab lus ntawm cov pa roj carbon ntau (feem ntau) ntawm cov pa roj carbon caij nplooj ntoos hlav steel feem ntau yog nyob nruab nrab ntawm {{0}}.62% thiab 0.90%. Raws li nws cov ntsiab lus manganese, nws tuaj yeem muab faib ua ob pawg: cov ntsiab lus manganese dav dav (feem ntau) (0.50% ~ 0.80%) xws li 65, 70, 85, thiab ntau dua manganese cov ntsiab lus (feem ntau. ) (0.90 ~ 1.20%) xws li 65Mn
Alloycaij nplooj ntoos hlav steel
Alloy caij nplooj ntoos hlav steel yog cov hlau uas txhim kho cov khoom siv kho tshuab, hardenability, thiab lwm yam khoom ntawm cov pa roj carbon steel los ntawm kev ntxiv ib lossis ob peb lub ntsiab lus alloying kom tsim nyog, txhawm rau ua kom tau raws li qhov yuav tsum tau ua rau kev tsim ntau yam springs.
Tsis tas li ntawd, qee qib ntawm lub caij nplooj ntoos hlav steel kuj raug xaiv los ntawm lwm yam hlau, xws li cov khoom siv hlau zoo, cov cuab yeej carbon steel, cov cuab yeej siv ceev ceev, thiab cov hlau tsis muaj steel.
txheej txheem kev ua tau zoo
Springs yog siv nyob rau hauv kev cuam tshuam, kev vibration, los yog lub sij hawm ntev cyclic kev nyuaj siab, yog li lub caij nplooj ntoos hlav steel yuav tsum muaj siab tensile zog, elastic txwv, thiab siab qaug zog. Nyob rau hauv cov nqe lus ntawm technology, nws yuav tsum tau hais tias lub caij nplooj ntoos hlav steel muaj tej yam hardenability, tsis yooj yim rau decarburize, thiab muaj zoo nto zoo, uas yog ib tug high-zoo carbon structural steel nrog ib tug carbon cov ntsiab lus WC nyob rau hauv qhov ntau ntawm 0 .6% -0.9%. Alloy caij nplooj ntoos hlav steel yog tsuas yog ua los ntawm silicon manganese series hlau, uas muaj ib tug me ntsis qis carbon cov ntsiab lus thiab tsuas yog txhim kho nws cov kev ua tau zoo los ntawm kev nce cov ntsiab lus ntawm silicon (Wsi); Tsis tas li ntawd, muaj alloy caij nplooj ntoos hlav steels ua los ntawm tungsten, tungsten, thiab vanadium. Nyob rau hauv xyoo tas los no, ua ke nrog Suav cov peev txheej thiab ua raws li cov kev xav tau ntawm cov thev naus laus zis tshiab rau kev tsim tsheb thiab tsheb laij teb, ib hom hlau tshiab tau tsim los ntxiv cov ntsiab lus xws li boron, niobium, thiab molybdenum rau silicon manganese steel, ncua kev pabcuam. lub neej ntawm springs thiab txhim kho lawv zoo.
