Lub ntsiab txhais ntawm caij nplooj ntoos hlav steel yog dab tsi?
Lub caij nplooj ntoos hlav steel yog cov khoom siv hlau tshwj xeeb uas paub txog nws cov elasticity thiab plasticity zoo heev. Nws yog ib qho hlau uas muaj ntau yam, xws li carbon, silicon, manganese, sulfur, phosphorus thiab lwm yam. Cov ntsiab lus thiab feem ntawm cov ntsiab lus no ua lub luag haujlwm tseem ceeb hauv cov yam ntxwv ntawm lub caij nplooj ntoos hlav steel, txiav txim siab nws cov khoom tseem ceeb xws li hardness, ductility thiab corrosion kuj.
Dab tsi yog qhov kev ua tau zoo ntawm lub caij nplooj ntoos hlav steel?
High elasticity: Lub ntsiab feature ntawm lub caij nplooj ntoos hlav steel yog ib tug high degree ntawm elasticity. Nws tuaj yeem tiv taus ntau qhov deformation yam tsis muaj kev tawg, nrog kev muaj zog resilience thiab rov qab muaj peev xwm. Txawm hais tias compressed, khoov los yog ncab, lub caij nplooj ntoos hlav steel sai sai rov qab mus rau nws lub qub qub, ua kom hloov elastic thiab lub zog cia. Qhov no ua rau lub caij nplooj ntoos hlav steel muaj ntau yam kev siv hauv ntau qhov chaw, xws li tsheb, tshuab, hluav taws xob, rooj tog thiab lwm yam.
High durability: Vim cov yam ntxwv ntawm cov khoom nws tus kheej, lub caij nplooj ntoos hlav steel muaj zoo heev durability. Nws tuaj yeem tswj xyuas cov khoom siv kho tshuab ruaj khov nyob rau hauv lub sijhawm ntev ua haujlwm siab zaus, thiab tsis yooj yim los tsim cov yas deformation thiab qaug zog tawg. Qhov no ua rau lub caij nplooj ntoos hlav steel dav siv nyob rau hauv ntau yam ntawm cov cuab yeej tseem ceeb thiab cov khoom siv elastic.
Zoo plasticity: Lub plasticity ntawm lub caij nplooj ntoos hlav steel txhais tau hais tias nws cov khoom muaj peev xwm tswj tau ib tug tej yam degree ntawm ductility thiab yooj thaum lub sij hawm deformation. Nws muaj cov khoom ua haujlwm txias txias zoo, thiab nws qhov hardness thiab lub zog tuaj yeem txhim kho los ntawm cov txheej txheem kho cua sov xws li cua txias thiab quenching, thaum tswj tau qee qhov qib ntawm plasticity. Qhov no ua rau lub caij nplooj ntoos hlav steel yooj yim rau kev ua thiab tsim thaum lub sijhawm tsim khoom.
Classification ntawm caij nplooj ntoos hlav steel
1. Kev faib tawm raws li tshuaj muaj pes tsawg leeg
Raws li GB / T 13304 tus qauv, lub caij nplooj ntoos hlav hlau tau muab faib ua cov hlau tsis muaj hlau (carbon caij nplooj ntoos hlav steel) thiab hlau hlau caij nplooj ntoos hlav raws li nws cov tshuaj muaj pes tsawg leeg.
carbon
Plain caij nplooj ntoos hlav steel
Cov ntsiab lus ntawm cov pa roj carbon monoxide (feem ntau) ntawm carbon caij nplooj ntoos hlav steel feem ntau yog {{0}}.62% rau 0.90%. Raws li nws cov ntsiab lus manganese, nws tau muab faib ua cov ntsiab lus ntawm manganese (feem ntau) (0.50% ~ 0.80%) xws li 65, 70, 85 thiab siab dua manganese cov ntsiab lus (feem ntau) (0.90 ~ 1.20% ), xws li 65Mn ob pawg.
Alloy caij nplooj ntoos hlav steel
Alloy caij nplooj ntoos hlav steel yog cov hlau uas yog raws li cov pa roj carbon steel thiab txhim kho cov khoom siv kho tshuab, hardenability thiab lwm yam khoom ntawm cov hlau los ntawm kev ntxiv ib lossis ob peb alloying ntsiab kom tsim nyog kom tau raws li qhov yuav tsum tau muaj ntawm ntau yam springs.
Cov khoom tseem ceeb ntawm alloy caij nplooj ntoos hlav steel series yog silicon manganese caij nplooj ntoos hlav steel, silicon chromium caij nplooj ntoos hlav steel, chromium manganese caij nplooj ntoos hlav steel, chromium vanadium caij nplooj ntoos hlav steel, tungsten chromium vanadium caij nplooj ntoos hlav steel thiab hais txog. Raws li cov koob no, qee qib tau ntxiv cov ntsiab lus hlau xws li molybdenum, vanadium lossis boron txhawm rau txhim kho qee yam ntawm lawv qhov kev ua tau zoo.
Tsis tas li ntawd, qee cov qib raug xaiv raws li lub caij nplooj ntoos hlav steel los ntawm lwm hom hlau, xws li cov khoom siv zoo carbon steel, cov cuab yeej carbon steel, cov cuab yeej siab ceev steel, stainless hlau.
Thib ob, raws li kev tsim khoom thiab kev ua haujlwm tau muab cais tawm
A. Kub dov (forged) steel muaj xws li kub dov round steel, square steel, ca steel, steel phaj, forged round steel, square steel.
