Annealing yog txheej txheem kev kho cua sov rau stainless hlau welded kav.Nws lub hom phiaj yog txhawm rau tshem tawm cov kev ntxhov siab uas seem, ruaj khov qhov ntev, thiab txo qhov nyiam ntawm deformation thiab tawg.
Dab tsi yog annealing ntawm 2205 stainless hlau yeeb nkab?
Nrog rau cov yeeb nkab uas ua los ntawm kev ua haujlwm txias, carbide nag lossis daus, lattice defects, thiab cov qauv tsis sib xws thiab muaj pes tsawg leeg yuav ua rau corrosion tsis kam ntawm stainless hlau poob.Lub sijhawm no, kev kho mob annealing (lossis kev daws teeb meem) yog xav tau.
Vim li cas 2205 stainless hlau yeeb nkab annealed?
Txo qhov hardness ntawm steel thiab txhim kho cov yas kom yooj yim txiav thiab txias deformation ua
Kho cov nplej, homogenize steel qauv thiab muaj pes tsawg leeg, txhim kho cov khoom steel lossis npaj rau kev kho cua sov tom ntej
Tshem tawm cov seem sab hauv kev ntxhov siab hauv cov hlau kom tsis txhob deformation thiab tawg.
2205 stainless hlau raj annealing txheej txheem
Hauv kev tsim khoom, cov txheej txheem annealing yog dav siv.Raws li lub hom phiaj sib txawv ntawm annealing xav tau los ntawm lub workpiece, muaj ntau yam txheej txheem annealing, feem ntau siv yog kev ntxhov siab nyem annealing, ua tiav annealing thiab spheroidizing annealing.
Kev nyuaj siab nyem annealing.Cov cuab yeej siv rau kev ntxhov siab annealing ntawm stainless hlau tubes yog ib qho txuas ntxiv ci ntsa iab rau cov hlau stainless, uas yog hom muffle ci ntsa iab annealing rauv.Qhov chaw tiv thaiv roj tau txais cov ammonia decomposition rauv thiab yog nruab nrog cov khoom siv roj purification. Hangao Tech (SEKO Machinery) tau ua tiav cov qauv kev hloov pauv ntawm lub tshuab hluav taws xob muffle, tshem tawm cov txheej txheem ntawm kev siv mesh conveying thiab hloov nws nrog txuas txuas ib leeg-tub rau cov menyuam conveying ntawm kab.Cov cuab yeej muaj cov yam ntxwv ntawm kev tswj hwm qib siab, kev txuag hluav taws xob zoo tshaj plaws, kev saib xyuas yooj yim, thiab lwm yam. Qhov chaw cua sov ntawm tag nrho cov kab siv PID tsis siv neeg ntau thaj tsam kub tswj.Stainless hlau kav dej kub-kho los ntawm peb Thaum tshav kub kub preservation stainless hlau yeeb nkab ci annealing rauv txo deformation thiab xyuas kom meej lub ellipticity ntawm cov kav dej.
Stainless hlau strips yog sib npaug ntawm cov khoom noj khoom haus, xa mus rau lub qhov cub annealing los ntawm txoj siv conveyor, rhuab mus rau 1050-1080 ℃ nyob rau hauv kev tiv thaiv ntawm ib puag ncig tswj, thiab tom qab ntawd khaws cia rau lub sijhawm luv luv, tag nrho cov carbides tuaj yeem yuav yaj nyob rau hauv lub qhov cub annealing.Nyob rau hauv cov qauv austenite, thiab tom qab ntawd txias txias kom qis dua 350 ° C, cov khoom siv supersaturated, uas yog, cov qauv unidirectional austenite tuaj yeem tau txais.
Ua kom tiav.Nws yog siv los kho cov qauv coarse superheated nrog cov khoom siv tsis zoo tom qab casting, forging thiab vuam ntawm nruab nrab thiab qis carbon steel.Ua kom sov lub workpiece mus rau qhov kub ntawm 30-50 ° C saum toj no qhov kub ntawm tag nrho cov ferrite hloov mus rau hauv austenite, tuav rau ib lub sij hawm, thiab maj mam txias nrog lub cub tawg.Thaum lub caij txias, lub austenite hloov dua siab tshiab, uas tuaj yeem ua rau cov qauv hlau nyias nyias..
Spheroidizing Annealing.Nws yog siv los txo qhov siab hardness ntawm cov cuab yeej steel thiab bearing steel tom qab forging.Lub workpiece yog rhuab mus rau 20-40 ° C siab tshaj qhov kub ntawm cov hlau pib tsim austenite, thiab maj mam txias tom qab tshav kub preservation.Thaum lub sij hawm txias txheej txheem, lamellar cementite nyob rau hauv lub pearlite ua spherical, yog li txo cov hardness.
