Hlau yog qhov tseem ceeb ntawm tus hniav. Yog lawm, hlau tsis yog tsuas yog ntsuas ntawm rab riam zoo. Cov cim tseem ceeb suav nrog cov duab thiab lub ntsej muag tawv, qhov qib ntawm kev nplij siab ntawm nws tus kov, cov ntaub ntawv tau siv rau kev tsim khoom ntawm txhua lub ntsiab ntawm cov khoom Tab sis paub tsuas yog muaj pes tsawg leeg cov hlau, ib qho tuaj yeem ntsuas qhov zoo ntawm rab riam.
Txawm tias cov pib xyaum ua tuaj yeem tuaj yeem xav tias rab riam ua los ntawm cov hlau tsis zoo yuav ua rau nrawm thiab txhawm, thaum txha hniav ua rau cov qib nyuaj ntawm cov hlau uas muaj cov pa roj carbon ntau yuav tawg thaum ua kom hnyav. Yog li, nws yog qhov tseem ceeb heev ntawm no mus xaiv rau "lub ntsiab lus kub".
Dab tsi yog suav nrog hauv cov hlau
Hauv cov ntsiab lus yooj yooj yim, hlau tsuas yog ua ke ntawm hlau thiab carbon. Nyob rau tib lub sijhawm, yog tias cov alloy muaj cov pa roj carbon ntau dhau, ces qhov tshwm sim yuav raug muab pov tawm hlau, thiab yog tias, ntawm qhov tsis sib xws, tsawg dhau, tom qab ntawd, yog li ntawd, tin yuav tawm los. Tab sis nyob rau hauv lub kub txhais tau tias yog hlau. Cov qeb sib txawv ntawm cov hlau no tau txiav txim siab tsis yog los ntawm cov feem ntau ntawm cov pa roj carbon thiab hlau muaj nyob rau hauv nws cov muaj pes tsawg leeg, tab sis los ntawm ntau yam kev cuam tshuam thiab ntxiv uas muaj qhov sib txawv ntawm tus cwj pwm ntawm cov khoom lag luam steel. Feem ntau, muaj pes tsawg leeg ntawm cov hlau hauv cov sib txawv sib txawv xws li chromium, carbon, silicon, molybdenum, tungsten, nickel, vanadium, sulfur.
Hlau rau zus tau tej cov riam
KHVG steel, ib qho nyuaj-alloyed tsis kub-tsis xeb hlau ntawm siab hardness, tshwj xeeb yog nyiam ntawm cov kws ua txuj ci rau kev txiav cov cuab yeej. Vim tias qhov tseeb ntawm steel deforms me ntsis thaum quenching, cov hniav ua ntawm nws yog qhov yooj yim heev rau kev tsim khoom, txig hliav thiab muaj nruab nrog lub zog zoo ntawm cov txiav txiav. Nyob rau tib lub sijhawm, qib hlau no muaj qhov tsis muaj zog tiv thaiv corrosion, uas yog vim li cas cov khoom lag luam steel ntxiv ntxiv blued lossis chrome plated.
Kev kho mob steel
Lub 65X13 hom yog koom nrog cov pab pawg ntawm cov tub luam nrov tshaj plaws rau kev tsim riam. Daim ntawv "x" hauv lub npe ntawm qib thim cov xim chromium nyob rau hauv nws cov muaj pes tsawg leeg, uas yog hais txog hlau rau qhov kev txiav txim ntawm stainless hlau. Cov phais taub hau thiab lwm yam cuab yeej siv kho mob feem ntau yog ua los ntawm cov hlau no, raws li lub npe nws tus kheej qhia. Qhov no yog tus hlau mos, riam los ntawm nws tau nrawm dua, tab sis lawv kuj yooj yim npub, thiab qhov tsis zoo ntawm qhov tsis xws li suav nrog qhov tseeb tias nws tiag tiag tsis xeb. Kev kho mob steel yog siv rau kev tsim txhua yam ntawm cov neeg siv khoom lag luam hauv tsev rau riam riam ua haujlwm, nrog tus nqi ntsuas zoo tsim nyog.
Tuam hlau
Rau kev tsim cov cuab yeej kev lag luam, lub thwj cim, tes xuas tes, X6VF hom yog siv. Riam ua los ntawm qib steel no muaj cov txiav txiav hnyav tsis kam ua haujlwm ua ke nrog kev muaj zog zoo thiab tiv taus xeb. Cov cuab yeej steel yog qhov zoo tshaj plaws rau kev tsim cov rab riam luv luv.
