Cov txheej txheem tseem ceeb tswj txoj kev ntawm quenching ntau lawm txheej txheem ntawm cov khoom siv hluav taws xob ntau zaus

1. Thaum lub sij hawm tsim cov txheej txheem, cov xaim hla lub log, cov log tsheb, cov phaj traction thiab lub thawv nyob rau hauv qhov chaw them nyiaj thiab nqa khoom yuav tsum xyuas kom meej tias qhov chaw ntawm cov hlau tsis raug puas.

2. Lub raj cua sov yuav tsum tau hloov ib zaug txhua peb lub hlis, thiab ua cov ntaub ntawv. Ceramic hais nyob rau hauv lub vibration tu lub thawv yuav tsum npog lub steel hlau nruj nreem, yog hais tias tsis, ntxiv nws nyob rau txhua lub sij hawm.

3. Thaum cov hlau xaim tawm ntawm lub cub tawg, nws yuav tsum tau muab cais rau ntawm lub spool, thiab tib lub sij hawm, lub phab ntsa ntawm lub cub tawg yuav tsum tsis txhob hnav.

4. Cov charcoal thiab npog tus neeg sawv cev ua ntej cov hlau xaim nkag mus rau cov kua txhuas yuav tsum tau khaws cia ntawm qhov tuab ntawm 10-15 cm. Tom qab txhua txoj kab hluav taws xob tsim tawm, cov hluav taws xob yuav tsum tau hloov, thiab cov hlau lead slag yuav tsum tau ntxuav tib lub sijhawm. Cov charcoal ntawm qhov chaw yuav tsum tau khaws cia noo. Thaum cov charcoal ua grey-dawb, cov charcoal yuav tsum tau hloov tam sim ntawd los xyuas kom meej tias cov charcoal npog nruj nreem kom tsis txhob muaj huab cua nkag mus thiab ua rau saum npoo ntawm cov hlau hlau yuav oxidized.

5. Lub voj voog ntawm tus neeg sawv cev npog hauv nruab nrab ntawm lub lauj kaub hlau yog ob lub hlis. Thaum nws siv rau ib hlis, 6 mus rau 8 lub hnab ntawm cov khoom nruab nrab yuav tsum tau ntxiv; Thaum nws yog lub hlis thib ob, tag nrho cov khoom siv nruab nrab tshiab (800 kg) yuav tsum tau hloov. Nyob rau tib lub sijhawm, ntxuav cov hmoov lead slag thiab cov hmoov lead oxide, thiab xyuas kom meej tias cov hmoov lead ua kua theem tau khaws cia rau hauv lub xeev ua haujlwm ntawm 430-450mm ( ntsuas ib lub lis piam ib zaug thiab ua cov ntaub ntawv. yuav tsum tau ntxiv rau lub sijhawm).

6. Thaum lub sij hawm siv lead ua av, vim yog co ntawm cov hlau hlau, yuav muaj ib qho tshwm sim ntawm “kev khawb qhov”, uas yuav tsum tau nqa nrog duav txhua lub sijhawm. Thaum cov hmoov txhuas tsis txaus, ntxiv rau lub sijhawm.

7. Thaum lub sij hawm kho cua sov ntawm cov hlau hlau, cov nyiaj them poob qis yuav tsum tau hloov kho raws li txoj kab uas hla ntawm cov hlau txias txias. Tom qab kev kho cua sov, txoj kab uas hla ntawm cov hlau yuav tsum tau ntsuas peb zaug ntawm lub taub hau, nruab nrab thiab tus Tsov tus tw ntawm cov hlau hlau. Thaum ci Φ3.0, Φ3.45, Φ3.8 steel hlau, hla-hlaws hlau seem ntawm lub taub hau ntawm txhua kauj ntawm kaum ntawm meters yuav tsum tau cim nrog xim daj, thiab cim kom meej meej ntawm daim ntawv tshaj tawm txhua hnub thiab daim npav ua haujlwm. .

8. Cov spools ua ntej thiab tom qab lub lauj kaub hlau lead thiab cov spools yuav tsum tau kuaj ib zaug txhua peb lub rauv kab tom qab ntau lawm. Yog tias qhov hnav hnyav, qhov kev taw qhia axial yuav tsum tau hloov kho lossis hloov.

9. Thaum lub sij hawm tsim khoom, nws yog nruj me ntsis txwv tsis pub cov hlau hlau yuav tsum tau twisted nyob rau hauv lub lauj kaub hlau lead, uas yuav ua rau cov hlau lead. Yog tias muaj cov hlau lead dai, nws yuav tsum tau ua raws sijhawm.

10. The cooling water temperature of the lead pot should be controlled below 60°C for 1# furnace and below 60°C for 2# furnace.

Hauv qab 80 ° C, lub qhov tshuaj tsuag yuav tsum tsis muaj kev cuam tshuam los xyuas kom meej tias cov hlau hlau tsis ua npuas ntau dhau thiab vapors thaum nws nkag mus rau cov kua qaub.
