Hais txog qhov txias txias ntawm Hniav cov kav hlau stainless hlau hauv cov txheej txheem ntau lawm, cov kev tseev muaj kev xav tau ntawm no yog ntau heev. Piv txwv li, yog tias ntsuas kub tsis zoo, ua rau lub cim ntawm 316 thermal kev ntxhov siab thiab kev ntxhov siab, cov yeeb nkab steel yuav tawg lossis deform. Tom ntej no, Hangao Tech (Seko Machinery) yuav qhia nyob rau hauv kev nthuav dav ntawm kev paub ntawm kev tsim cov khoom zoo nkauj stainless kav rau cua txias:
Vim yog kev faib tawm ntawm sab hauv kev ua kom zoo nkauj thaum ua kom zoo nkauj stainless hlau raj yuav deformed, thiab kev ua qhov raug yog tsis tuaj yeem lav. Tsis tas li ntawd, tuav qhov feem ntau yog nquag muaj kev ntxhov siab uas muaj kev ntxhov siab. Tag nrho cov no stainless hlau hlua khi yuav tsum nres kev ntxhov siab tom qab ntxhib machining. Qhov kev tshem tawm ntawm kev ntxhov siab sab hauv annaling feem ntau yog kom kho cov raj hlau stainless hlau. Ntawm 500-550 ° C, nws tau siv yav tas los ntawm chav tsev kub txog li 50 mus rau 5 teev lossis ntau dua (nyob ntawm tus naj npawb ntawm cov chaw ua kom haum rau lub sijhawm ntev. Nws yog hu ua kev laus ntuj, tab sis tus qauv no dhau ntev thiab feem ntau tsis siv.
Thaum lub raj hlau tsis muaj zog dai cov raj yog txias, cov nplaim thiab ib co nyias feem ntau ua kom dawb, nyuaj, txho xim dawb. Yog li no, zoo tib yam stainless hlau zoo nkauj khau yuav tsum tau annealed los yog qauv los tshem tawm cov khoom tsis xws luag. Qhov annealing lossis qhov ntsuas kub feem ntau yog nruab nrab ntawm 850 thiab 950 ° C. Qhov ntsuas kub yog tswj hwm rau 1-2 teev, ua kom qab zib yog synthesite hauv graphite thiab Austenite (thawj theem ntawm graphitization). Peb li Kev ua lag luam online txuas ntxiv ci ntsa iab muaj peev xwm pab koj. Nws tsis tas yuav muaj preheating, nws tuaj yeem ncav cuag cov anealing zoo tshaj plaws nyob hauv 10 feeb tom qab pib.
Ntxiv mus, nws txuas nrog rau PLC system, koj tuaj yeem pom ncaj qha cov ntaub ntawv ntawm cov ntaub ntawv ntawm huab cua siab, dej ntws, ua haujlwm kub, ceev. Lub sijhawm tom ntej txias ntawm lub cub tawg, hloov pauv theem nrab thiab Eutectoid cementite yuav ua rau cov khoom siv hauv graphite (piv txwv li theem ob ntawm graphitization). Thaum kawg, Perlite tau ntxiv rau cov ferrite lossis ferrite matrix los txo qhov nyuaj thiab lub zog ntawm lub pov. Ib qho ntxiv, cov txheej txheem cementing yog 850-950 ° C, tab sis cov xis nyob hauv lub zog ua kom zoo nkauj, tuaj yeem tau txais cov khoom siv kom zoo nkauj ntawm lub zog thiab hardness ntawm lub hlaws matrix ua ke.
