Ua ntej, preheating:
1. Rau qhov ua haujlwm nrog cov duab nyuaj lossis cov kev hloov pauv sib txuas thiab tuab tuab, nws yuav tsum yog preheated
2. Cov txheej txheem ntawm preheating yog: ib lub preheating rau 800 ℃, theem nrab-theem nrab yog 500 ~ 550 ℃, qhov ntsuas kub nce siab yuav tsum tau txwv
Ob, Cua Sov:
1. Muaj cov tsis yog cov neeg nyob hauv qhov chaw ua haujlwm, nrum thiab av stainless hlau workpiece, feem ntau tsis nyob hauv qab ntsev ua cua sov cua sov
2. Xyuas kom meej tias qhov workpiece yog rhuab rau lub sijhawm txaus. Xam cov tuab tuab ntawm cov workness (qhov tiag tiag tuab (qhov tseeb tuab lias los ntawm workpiece duab coefficient) los ntawm hais txog lub rooj 5-16 thiab rooj 5-17
Peb, Tu:
1. Lub workpiece thiab fixture yuav tsum muaj roj, seem ntsev, pleev xim thiab lwm cov khoom txawv teb chaws ua ntej kev kho cua sov
2. Cov ntawv siv rau thawj zaug hauv cov cua tshuab hluav taws xob yuav tsum tau degassed thiab lim kom ua ntej tsawg kawg hauv qab lub zog ua haujlwm yuav tsum tau los ntawm kev ua haujlwm
Plaub, rauv chaw thau khoom:
1. Nyob rau hauv cov txheej txheem ntawm kev kho cua sov, deformable workpiece yuav tsum tau rhuab rau ntawm ib qho tshwj xeeb fixture
2. Lub workpiece yuav tsum muab tso rau hauv thaj chaw ua cua sov zoo
