Kev piav qhia: J555 yog lub electrode ntsug downward nrog cov txheej cellulose potassium siab. AC thiab DC dual-purpose. thaum vuam downward, cov hlau molten thiab slag yuav tsis ntws mus rau hauv qab. Nws muaj lub zog arc zoo thiab nkag mus. Kev vuam hauv qab tuaj yeem tsim rau ob sab thiab muaj kev vuam ceev ceev.
Daim Ntawv Thov: Siv rau kev vuam cov kav hlau tsis tshua muaj hlau.
Cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov hlau vuam (%):
| C | Mn | Si | S | P |
| ≤0.20 | ≥1.00 | ≤0.50 | ≤0.035 | ≤0.035 |
Cov khoom siv kho tshuab ntawm cov hlau vuam:
| Khoom sim | Lub zog tensile Mpa | Lub zog tawm los Mpa | Kev ntev % | Tus nqi cuam tshuam (J) -30 ℃ |
| Tau lees paub | ≥540 | ≥440 | ≥17 | ≥27 |
Kev tshuaj xyuas X-ray: qib II
Pom zoo tam sim no:
| (hli) Txoj kab uas hla ntawm tus pas nrig | 2.5 | 3.2 | 4.0 | 5.0 |
| (Ib) Vuam Tam Sim No | 45 ~ 75 | 80 ~ 120 | 130 ~ 160 | 170 ~ 190 |
Daim Ntawv Ceeb Toom:
Ua ntej siv, lub electrode yuav tsum tau ci ntawm 70-90 ° C rau 1 teev. Qhov kub yuav tsum tsis txhob siab dhau, txwv tsis pub cov cellulose hauv txheej yuav puas tsuaj.
Wenzhou Tianyu Electronic Co., Ltd. tau tsim muaj xyoo 2000. Peb tau koom nrog kev tsim khoom ntawmvuam electrodes, cov pas nrig vuam, thiab cov khoom siv vuam rau ntau tshaj 20 xyoo.
Peb cov khoom tseem ceeb suav nrog stainless hlau vuam electrodes, carbon hlau vuam electrodes,cov hlau tsis tshua muaj hlau vuam electrodes, cov electrodes vuam surfacing, cov electrodes vuam nickel & cobalt alloy, cov hlau tsis muaj zog & cov hlau tsis tshua muaj zog vuam, cov hlau stainless hlau vuam, cov hlau flux cored uas tiv thaiv roj, cov hlau vuam txhuas, cov hlau vuam submerged arc. cov hlau, cov hlau vuam nickel & cobalt alloy, cov hlau vuam tooj dag, cov hlau vuam TIG & MIG, cov hlau tungsten, cov hlau carbon gouging, thiab lwm yam khoom siv vuam & cov khoom siv tau.
