Kev piav qhia: T107 yog lub electrode tooj liab ntshiab nrog tooj liab ntshiab ua lub hauv paus thiab npog nrog cov dej ntws sodium tsawg-hydrogen. Siv DCEP (direct current electrode positive). Cov khoom siv kho tshuab zoo, tiv taus corrosion zoo rau huab cua thiab dej hiav txwv, tsis haum rau kev vuam tooj liab uas muaj oxygen thiab tooj liab electrolytic.
Daim Ntawv Thov: Nws feem ntau yog siv rau kev vuam cov khoom siv tooj liab xws li cov hlau tooj liab conductive, cov khoom siv pauv cua sov tooj liab, thiab cov kav dej hiav txwv rau cov nkoj. Nws kuj tseem siv tau rau kev vuam nto ntawm cov hlau carbon uas tiv taus kev xeb dej hiav txwv.
Cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov hlau vuam (%):
| Cu | Si | Mn | P | Pb | Fe+Al+Ni+Zn |
| >95.0 | ≤0.5 | ≤3.0 | ≤0.30 | ≤0.02 | ≤0.50 |
Cov khoom siv kho tshuab ntawm cov hlau vuam:
| Khoom sim | Lub zog tensile Mpa | Kev ntev % |
| Tau lees paub | ≥170 | ≥20 |
Pom zoo tam sim no:
| Txoj kab uas hla ntawm tus pas nrig (hli) | 3.2 | 4.0 | 5.0 |
| Kev vuamTam sim no (Ib) | 120 ~ 140 | 150 ~ 170 | 180 ~ 200 |
Daim Ntawv Ceeb Toom:
1. Lub electrode yuav tsum tau ci ntawm li 200 ° C rau 1 teev ua ntej vuam, thiab cov dej noo, roj, oxides thiab lwm yam impurities ntawm qhov chaw ntawm qhov vuam yuav tsum tau tshem tawm.
2. Vim yog lub thermal conductivity ntawm tooj liab, thiab qhov kub ua ntej ntawm cov ntoo uas yuav tsum tau welded feem ntau yog siab heev, feem ntau siab dua 500 ° C. Qhov loj ntawm qhov tam sim no vuam yuav tsum sib xws nrog qhov kub ua ntej ntawm cov hlau hauv paus; Sim ntsug luv luv arc vuam. Nws tuaj yeem siv rau kev txav mus los sib pauv kom txhim kho kev tsim vuam.
3. Yog xav vuam ntev dua, sim siv txoj kev vuam kauj ruam rov qab, thiab qhov ceev vuam yuav tsum ceev li sai tau.
Thaum vuam ntau txheej, cov slag ntawm cov khaubncaws sab nraud povtseg yuav tsum tau tshem tawm tag nrho; tom qab vuam, rauj lub vuam nrog lub taub hau tiaj tus rauj kom txo qhov kev ntxhov siab,
Txhim kho qhov zoo ntawm vuam.
