1. galvanized kav thiab fixtures yuav tsum tshem tawm cov khoom txawv teb chaws xws li roj, residual ntsev, thiab pleev xim rau ua ntej thermal kho;
2. Cov khoom siv hauv lub tshuab nqus tsev rau thawj zaug yuav tsum tau nqa tawm ua ntej ntawm lub tshuab nqus tsev vacuum xav tau los ntawm workpiece;
3. Nyob rau hauv lub workpiece uas yooj yim deform thaum lub sij hawm thermal kho, cua sov yuav tsum tau ua nyob rau hauv ib tug tshwj xeeb fixture. Txoj kev preheating yog: 1 preheating ntawm 800 degree C, thiab theem nrab preheating ntawm 500-550 degree C thiab 850 degree C. Qhov kub ceev ceev ntawm ib lub sij hawm yuav tsum tau txwv;
4. Rau workpieces nrog ib tug ntse hloov nyob rau hauv cov duab los yog cross-section, thiab zoo thickness workpiece, preheating yuav tsum tau ua;
5. Cov neeg ua haujlwm, castings thiab welded qhov chaw uas tsis muaj qhov pores, thiab stainless hlau workpieces uas tau ua tiav thiab tsim feem ntau tsis haum rau cua sov hauv lub qhov cub ntsev;
6. Raws li qhov ua tau zoo thiab cov thickness ntawm lub workpiece (qhov tseeb thickness yog multiplied los ntawm cov duab coefficient ntawm workpiece), cov cua kub ntawm cov yeeb nkab galvanized yuav tsum muaj lub sij hawm txaus rwb thaiv tsev;
7. Martiner stainless hlau thiab kub-resistant steel galvanized yeeb nkab quenching nws yog txias kom txog rau thaum chav tsev kub yuav tsum tau ntxuav, sib sib zog nqus-txias kev kho mob los yog rov qab. Lub sijhawm luv ntawm vuam thiab kev kho cua sov tom ntej yuav tsum tsis pub tshaj 4 teev;
8. Ntxuav alkaline ntxuav, dej -soluble tu tus neeg saib xyuas, chlorine hnyav, tshuaj tsuag thiab lwm yam kev raws li qhov yuav tsum tau thiab nto tej yam kev mob ntawm cov kav dej galvanized;
9. Tom qab kho, qhov txo qis dehuminar yuav tsum tau ua hauv qab qhov hluav taws kub qub. Cov duab yog qhov nyuaj los yog qhov loj yuav tsum nruj workpieces. Tom qab kev kho, siv ib lub fixture los muab cov hluav taws los kho nws;
10. Thaum qhov kev ua tau zoo ntawm cov kav dej galvanized yog tsis tsim nyog, rov ua dua thermal kev kho mob tuaj yeem ua tau, tab sis tus naj npawb ntawm cov quenching rov qab los yog cov khoom siv tshuaj feem ntau tsis ntau tshaj ob zaug. Kev rov ua dua ntawm cov yeeb nkab galvanized tsis suav tias yog kev kho dua tshiab. Cov xwm txheej quenching lossis qis-kub rov qab ntawm cov phooj ywg-generated stainless hlau thiab kub-resistant steel workpiece yuav tsum tau preheated ua ntej rov quenching, annealing los yog kub rov qab.
