1. Yog vim li cas:
Kev tshem tawm ntawm kev ntxhov siab sab hauv:Hauv kev tsim thiab ua cov yeeb nkab stainless hlau fittings, xws li stretching, dabtsi yog khoov thiab molding txheej txheem, loj sab hauv kev ntxhov siab yog qhia. Lub xub ntiag ntawm kev ntxhov siab sab hauv cuam tshuam rau kev ruaj ntseg thiab kev ua haujlwm ntawm cov khoom siv thiab tuaj yeem ua rau deformation, tawg thiab lwm yam teeb meem. Annealing tuaj yeem tshem tawm cov kev ntxhov siab sab hauv.
Restoration ntawm toughness: Stainless hlau yuav ua hauj lwm hardening thaum lub sij hawm ua, ua cov khoom ntau nkig. Annealing tuaj yeem ua rau cov nplej loj hlob rov qab los ntawm cov txheej txheem recrystallization, rov ua kom lub zog thiab ductility ntawm cov khoom, yog li txhim kho kev ua haujlwm thiab kev pabcuam lub neej ntawm cov yeeb nkab fittings.
Kev txhim kho ntawm lub koom haum qauv:Thaum lub sij hawm ua, cov qauv ntawm cov hlau tsis muaj steel yuav hloov, nrog cov nplej tsis sib xws los yog cov nplej tsis zoo. Annealing tuaj yeem ua rau cov nplej rov ua kom sib npaug, tsim kom muaj lub koom haum ruaj khov, yog li txhim kho cov khoom siv kho tshuab ntawm cov khoom.
Txhim kho corrosion kuj:Kev tiv thaiv oxide txheej ntawm cov khoom siv hlau tsis muaj steel hlau yuav raug puas tsuaj tom qab ua hauj lwm hardening. Annealing kev kho mob tuaj yeem pab kho thiab txhim kho cov txheej txheem oxide nyob rau saum npoo ntawm stainless hlau, yog li txhim kho nws cov corrosion kuj.
2. Txheej txheem
Cua sov:Stainless hlau nias-hom fittings yog rhuab mus rau ib tug tej yam kub thiab txias, feem ntau ntawm 950 degree thiab 1150 degree. Qhov ntsuas kub no nyob ntawm qhov tshwj xeeb alloy ntawm stainless hlau. Qhov ntsuas kub no nyob ntawm qhov tshwj xeeb alloy muaj pes tsawg leeg ntawm stainless hlau.
Tuav:Tom qab cua sov rau lub hom phiaj kub, ib lub sij hawm ntawm lub sij hawm yog tuav los xyuas kom meej ib tug uniform kub nyob rau hauv lub workpiece, tso cai rau cov kev ntxhov siab nyob rau hauv tag nrho tso tawm thiab cov khoom qauv yuav tsum tau kho. Lub sijhawm tuav yog nyob ntawm qhov loj thiab tuab ntawm lub workpiece, feem ntau ntawm ib nrab teev thiab ob peb teev.
Slow Cooling:Tom qab annealing, lub workpiece yuav tsum tau ua kom txias maj mam kom tsis txhob muaj kev ntxhov siab tshiab los ntawm kev tsim los ntawm kev ua kom txias sai. Cov txheej txheem ua kom txias tuaj yeem yog qhov cua txias hauv huab cua lossis txias txias hauv qhov cub. Cov txheej txheem txias sib txawv yuav muaj kev cuam tshuam rau cov khoom siv kawg.
3. Cov txiaj ntsig
Kev ntxhov siab:Tom qab annealing, residual stresses nyob rau hauv stainless hlau fittings raug tso tawm, txo qhov kev pheej hmoo ntawm kev ntxhov siab vim distortion thiab cracking.
Txhim kho toughness:Lub annealed stainless hlau regains nws toughness thiab ductility thiab yog zoo dua los tiv thaiv cov kev nyuaj siab ntawm tom qab ua thiab siv.
Uniformity ntawm lub koom haum:Cov qauv nplej yog homogenized, txo cov teeb meem xws li grain ciam teb corrosion thiab txhim kho cov khoom siv thiab kev pab lub neej ntawm cov khoom.
Txhim kho corrosion kuj:los ntawm cov annealing los kho thiab ntxiv dag zog rau saum npoo passivation txheej, txhim kho corrosion kuj ntawm stainless hlau yeeb fittings, tshwj xeeb tshaj yog nyob rau hauv hnyav ib puag ncig nyob rau hauv daim ntawv thov ntawm lub neej.
Ua kom tiav, annealing yog ib feem tseem ceeb ntawm cov txheej txheem ntawm kev ua cov hlau tsis muaj steel xovxwm fittings, los ntawm kev kho annealing, koj tuaj yeem txhim kho qhov kev ua tau zoo ntawm cov fittings kom ntseeg tau tias lawv muaj kev ntseeg siab thiab siv tau ntev.
