Stainless hlau tubeKev kho cua sov lub hom phiaj tseem ceeb yog hloov cov yeeb nkab sab hauv hlau matrix qauv, txhim kho lub hardness ntawm stainless hlau yeeb nkab, tab sis vim nws tsis yog qhov tseem ceeb hloov cov yeeb nkab morphology, thiab yog li tsis tuaj yeem txhim kho lub zog thiab toughness ntawm stainless hlau raj.Stainless hlau raj quenching kub yuav tsum tau xaiv nyob rau hauv qhov tseem ceeb kub ntawm 30-70℃, vim tsis zoo thermal conductivity ntawm steel, lub sij hawm tuav yog feem ntau txog ob zaug nce dua hlau.

Lub caij no, txhawm rau txo qis kev ntxhov siab, ua ntej quenching yuav tsum nyob rau hauv huab cua ua ntej txias, roj quenching nruab nrab feem ntau siv quab yuam kom tsis txhob quench cracking kuj tuaj yeem siv roj thaum ntxov (txias rau 200-300.℃) cua txias txoj kev.Tom qab stainless hlau raj quenching, martensite matrix qauv tuaj yeem ua los yog troostite tom qab tempering tempered rau hauv sorbite, uas yog quenching, tempering txheej txheem thiab tempered stainless hlau yeeb nkab lwm cov yeeb nkab yog tsis muaj qhov tseem ceeb sib txawv tom qab quenching yuav tsum tempered stainless hlau.Stainless hlau tseem tuaj yeem yog isothermal quenching isothermal quenching nruab nrab yuav yog roj kub lossis nitrate, piv txwv li, ntawm 830-870℃, thiab ces rhuab quenched 280-350℃isothermal nitrate.Cov yeeb nkab steel quenching lossis isothermal quenching, txhim kho cov khoom siv dag zog dua li cov hlau cam khwb cia zoo ib yam zoo kawg li.

Txhawm rau txhim kho lub npoo hardness thiab hnav tsis kam ntawm cov yeeb nkab steel hlau, muaj tshuaj lom neeg cov khoom kub zaus lossis cov khoom siv sib npaug zaus ntawm cov ntawv thov.Siab, nruab nrab zaus nto hardening nrog lub sij hawm cua sov yog luv, tsawg oxidation thiab decarbonization, deformation yog me me, thiab yooj yim ua hauj lwm, lub cua kub kub yog feem ntau 850-950.℃, stainless hlau yeeb nkab vim tsis zoo thermal conductivity, thiab tsawg melting point, lub cua sov tus nqi tsis ceev heev, txwv tsis pub nws yuav tawg los yog melting.Siab, nruab nrab zaus ua stainless hlau raj tsis tsuas yog tuaj yeem txhim kho qhov tawv tawv thiab hnav tsis kam, tab sis kuj tseem txhim kho lub zog qaug zog, ua kom muaj kev pab cuam lub neej, lwm yam, Lub Tshuab Hluav Taws Xob Hluav Taws Xob tiv tauj saum npoo ntawm cov cua sov yog ib qho piv txwv ntawm stainless hlau. tube nto hardening.Yuav kom tau txais ib lub koom haum zoo matrix los xyuas kom meej cov hlau tsis muaj steel raj hauv qhov chaw hardening thiab cov khoom siv tshuab tuaj yeem tau txais tom qab siab hardness, kev kho cua sov saum npoo ua ntej qhov zoo tshaj plaws ua ntej normalizing lossis quenching thiab tempering kho.
