Cov Lus Qhia Txog Khoom
Cov Cim Npe Khoom
PIAV TXOG:
COBALTHARD 1FC coverd electrode yog qhov nyuaj tshaj plaws hauv pawg ntawm cov cobalt alloys siv rau kev hnav khaub ncaws kub siab uas cuam tshuam nrog kev xeb. Cov khoom tso rau hauv cov alloy no muaj ntau cov chromium carbides uas cuam tshuam rau kev hnav khaub ncaws zoo heev. Kev ntxiv ntawm tungsten ua rau qhov kub siab hardness thiab matrix toughness rau kev nplaum zoo heev thiab cov khoom tawg tsis kam hnav. Nws sib txuas zoo nrog txhua yam hlau, suav nrog stainless.
COV NTAWV THOV:
Cov tawv ntawm cov taub hau valve, cov nplhaib foob ntawm cov twj tso kua mis siab thiab cov khoom ntawm cov crushers.
Qhov nyuaj ntawm cov hlau vuam: 50 - 56 HRC (520- 620 Hv)
COV TSHUAJ YEEM NTAWM COV HLAU WELD (%):
| C | Si | Mn | Cr | W | Co |
| 2.15 | 0.47 | 1.03 | 31.25 | 12.72 | Bal |
TXOJ KEV VUAM: Tiaj, Ntsug, SAUM TOJ KAWG
Qhov Loj Muaj Thiab Cov Tam Sim No Pom Zoo (DC +):
| Loj (dia. hli) | 3.2 | 4.0 | 5.0 |
| Ntev (hli) | 350 | 350 | 350 |
| Tam sim no ntau yam (Amp) | 90 – 120 | 110 – 150 | 140 – 180 |
COV LUS CEEV TXOG KEV SIV:
Ua ntej kom sov ntawm 300ºC thiab ntau dua feem ntau.
Siv cov pas ntsuas kub PHILARC lossis lub ntsuas kub PHILARC interpass los txiav txim siab seb qhov kub puas ua tiav ua ntej vuam.
Nws zoo rau kev ua kom sov tom qab vuam ntawm 600ºC thiab qeeb qeeb txias tom qab vuam kom tiv thaiv kev tawg.
Ua ntej siv, ziab cov electrodes ntawm 150-200ºC rau 30 - 60 feeb. Siv cov qhov cub ziab PHILARC uas siv tau yooj yim.
Yav dhau los: ECoCr-A (Cobalt 6) Cobalt Hardfacing & Hnav-resistant Welding Electrode Tom ntej no: ENiCrFe-3 Electrodes rau Nickel
