3. Lub xeev thib ob thiab thib peb ntawm kev kho cua sov tom qab ua haujlwm txias yog raws li hauv qab no:
3. Qhov thib ob thiab thib peb ntawm kev kho cua sov tom qab ua haujlwm txias yog raws li nram no:
HR - ua haujlwm txias + kev ntxhov siab; HT - txias ua haujlwm + xaj kom muaj zog; HE - txias ua hauj lwm + kawg annealing
HR: HR01 - 1 / 4 nyuaj + kev ntxhov siab; HR02 - ib nrab nyuaj + thiab kev ntxhov siab; HR04 - nyuaj + thiab kev ntxhov siab; HR06 - nyuaj + thiab kev ntxhov siab; HR08 - elastic + thiab kev ntxhov siab; HR10 - siab elastic + thiab kev ntxhov siab; HR12 - tshwj xeeb elastic + thiab kev ntxhov siab; HR50 - kev kos duab + kev ntxhov siab; HR90 - fin forming + stress relief
HT: HT04 - nyuaj + xaj kom muaj zog; HT08 - elastic + xaj kom muaj zog
HE: HE 80 - hard drawing + end annealing
4. Qhov thib ob thiab thib peb theem sawv cev txoj kev ntawm annealing xeev (O):
Qhov thib ob thiab thib peb theem ntawm annealing xeev (O) muab faib ua ob txoj kev sawv cev: annealing kom tau raws li nominal nruab nrab grain loj thiab annealing kom tau raws li cov neeg kho tshuab zog.
1). Txoj kev qhia txog qib thib ob thiab qib thib peb annealing xeev uas ua tau raws li qhov nruab nrab nominal grain loj:
OS{{0}}Annealing nrog grain loj yuav tsum tau, peb tus lej ntxiv tom qab ntawd muab faib los ntawm 1000 yog qhov nominal nruab nrab grain loj, nyob rau hauv mm; Piv txwv li, qhov nominal nruab nrab grain loj ntawm OS005 yog 0.005mm, thiab nominal nruab nrab grain loj ntawm OS200 yog 0.2mm
2). Txoj kev qhia txog qib thib ob thiab qib thib peb annealing xeev uas ua tau raws li cov khoom siv tshuab:
O1--Casting xeev + kev kho cua sov; O2-- Kub forging + kev kho cua sov; O3-- Kub extrusion + kev kho cua sov; O4--Kev tho kub + kev kho cua sov; O{{8}Ntev thiab tempering annealing; O6--Kev sib tw; O7-- Ua tiav softening annealing; O8--Annealing rau cov khoom tshwj xeeb
O1: O10-- Casting + annealing (homogenization); O11-- Casting + nag lossis daus kub kho
O2: O20-- Kub forging + annealing; O25-- Kub dov + annealing
O3: O30-- Kub extrusion + Annealing; O40 - kub extrusion + nag lossis daus kub kho
O4: O40 - kub piercing + annealing
O5: O50 - lub teeb annealing
