Khoom Taw qhia
| Ntsiab lus qeb | Lub cim | Tshuaj lom neeg cov tshuaj lom neeg ntau npaum li cas (%) | Tub Ntxhais Kev Ua Haujlwm & Cov Lus Qhia |
|---|---|---|---|
| Cov ntsiab lus loj | C | 0.07 ~ 0.15 | Kev tswj hwm Weld lub zog: Cov ntsiab lus qis dhau lawm ua rau muaj zog tsis txaus, thaum ntau cov ntsiab lus yooj yim ua rau vuam cracks thiab txo nruj. |
| Mn | 1.40 ~ 1.85 | 1. Tubtxib Tes Haujlwm Loj yog lub ntsiab deoxidizer kom txo cov paj oxygen hauv weld thiab tiv thaiv porosity; 2. Refines nplej kom txhim kho Weld lub zog thiab tawv; 3. Txhim kho cov pas dej Funten. |
|
| Si | 0.80 ~ 1.15 | 1. Pab cov deoxidization muaj zog, ua haujlwm synergistically nrog MN kom txo cov pa oxygen; 2. Ua kom muaj weld hardness thiab lub zog; 3. Txhab rau Arc thiab txo cov ncauj lus. |
|
| Kev tsim txom cov impurity ntsiab | P | Tsawg dua los yog sib npaug rau 0.025 | Ib qho kev txwv tsis pub muaj kev phom sij uas yooj yim ua rau "kub brittleness" ntawm weld (txo cov vaj ntxwv thaum muaj kev tawg siab); Yuav tsum tau tswj hwm ntawm qib qis heev. |
| S | Tsawg dua los yog sib npaug rau 0.025 | Ib qho kev ua phem rau kev ua phem uas yooj yim "ntawm Weld (kev txo qis ntawm cov kev phom sij ntawm qis, nquag muaj kev pheej hmoo ntawm cov kab nrib pleb kub. | |
| Residual ntsiab | CU | Tsawg dua los yog sib npaug rau 0.50 | Feem ntau yog cov khoom seem uas tau qhia los ntawm cov ntaub ntawv raw; Ib qho me me tuaj yeem txhim kho wull corrosion tsis kam, tab sis cov ntsiab lus ntau dhau yuav ua rau kub tawm. |
| Ni | Tsawg dua los yog sib npaug rau 0.30 | Ib tug residual keeb nrog me ntsis cuam tshuam rau weld kev ua haujlwm; Tus qauv tsuas yog qhia cov kev txwv sab saud (tsis yog ib qho khoom lag luam). | |
| Cr | Tsawg dua los yog sib npaug rau 0.20 | Ib tug residual keeb; Ib qho me me tuaj yeem ua rau muaj zog me me, tab sis cov ntsiab lus ntau dhau yuav nce siab Weld tsis muaj peev xwm, yog li cov qauv teeb tsa ib qho kev txwv sab saud. | |
| Mo | Tsawg dua los yog sib npaug rau 0.15 | Ib qho seem uas tseem tshuav nrog kev cuam tshuam me ntsis ntawm Weld nruj; Tus qauv tsuas yog qhia cov kev txwv sab saud (tsis yog ib qho khoom lag luam). | |
| V | Tsawg dua los yog sib npaug rau 0.05 | Ib qho khoom seem uas tsis muaj qhov cuam tshuam tseem ceeb rau kev ua tau zoo thaum cov ntsiab lus tsawg heev; tus qauv teeb tsa ib qho kev txwv sab saud. |
