Peb theem thiab cov teebmeem hauv cov txheej txheem anealing

Hauv kev forging txheej txheem ntawm stainless hlau, 'annealing ' yog ib qho txheej txheem tseem ceeb. Annealing yuav tsum siv kev siv hluav taws xob, cov khoom siv annealing spnealing yog tsuas yog siv rau kev kho cua sov ua tiav rau cov huab cua tiv thaiv. Cov kev ua tau zoo sib txawv, qhov yuav tsum tau rau kev ci annealing rauv taws yog txawv, thiab kev kho cua sov kev lag luam tsis zoo ib yam. Cov txheej txheem kev kho cua sov raws li 300 series Austenitic Stainless hlau yeeb nkab yog cov kev kho teeb meem. Tus yuam sij rau txheej txheem kho cua sov no yog qhov txias nrawm rau hauv qab 35 ° C, tsim nyog cua sov kom nrawm nrawm mus tau txais cov qauv ua kom qeeb kom tau txais cov qauv siv qeeb.

Thiab, peb theem ntawm 'analing ' yuav ua rau koj cov yeeb nkab yeeb nkab ci ci thiab ruaj khov. Firstly theem cua sov, cov yeeb nkab theem, cov yeeb nkab stainless hlau yog nyob rau hauv cov kab ke kaw, thiab nws yog qhov tsim nyog yuav tsum tau kaw thiab tsis pub cua toking. Vim tias nws yog rhuab nyob rau hauv kev txo cov cua ntawm cov roj hauv cov roj thiab tib yam kub tau rov qab mus rau cov khaub ncaws hnav thiab zoo nkauj. Thib ob, rwb thaiv tsev theem, ntsuas kub ntawm cov yeeb nkab stainless hlau yog insulationing thiab ruaj khov rau ib lub sij hawm ntawm cov ciaj ciam ntawm cov khoom sib txawv chromium tsis txaus thiab tsis txhob muaj ntau tiam neeg ntawm intercraphion. Cov yeeb nkab steel tom qab kev kho mob stabiliat muaj cov khoom siv zoo dua thiab xeb kuj. Qhov thib peb, theem txias txias, cov yeeb nkab stainless siv cov txiaj ntsig me me kom tsis txhob ua kom sov, thiab kev txiav txim siab tsis muaj oxidation thiab kev txiav txim siab tsis muaj oxidation thiab zoo corrosion tsis kam.

Nyob rau hauv cov txheej txheem ntawm annealing, tseem muaj qee qhov yuav tsum tau ua rau lub rauv taws, thiab saib xyuas kom muaj kev tiv thaiv kom muaj kev tiv thaiv hluav taws xob. Lub annealing rauv siv hydrogen raws li cov roj tiv thaiv. Thaum Hydrogen Leaks, nws tuaj yeem ua rau muaj kev txaus ntshai kom sawv thiab khaws hauv cov qauv ntauwd. Yog li peb yuav tsum nqis tes ua kev ntsuas kom muaj kev nyab xeeb.
