Ruzivo rweChigadzirwa
Matagi eChigadzirwa
TSANANGURO:
COBALTARD 1FC covered electrode ndiyo yakanyanya kuomarara muboka re cobalt alloys inoshandiswa pakuora kwakanyanya pakupisa. Madhayi e alloy iyi ane huwandu hwakawanda hwe chromium carbides inokanganisa kuramba kupisa kwakanyanya. Kuwedzerwa kwe tungsten kunowedzera kuomarara pakupisa kwakanyanya uye kusimba kwe matrix kuti inamire zvakanaka uye irambe yakasimba pakuora. Inobatanidza zvakanaka nesimbi dzese, kusanganisira stainless steel.
ZVINOSHANDISWA:
Kuisa pamusoro pemisoro yemavharuvhu, mhete dzekusimbisa dzakagadzirwa nepombi ine simba rakawanda uye zvikamu zvemacrusher.
KUOMA KWESTEAL DEPOSIT YEWELD: 50 – 56 HRC (520- 620 Hv)
KUUMBIKA KWEMAKEMIKIRI AKAJAIWA EWELD STAR (%):

Nzvimbo Yekunamira: Yakati sandara, Yakamira Mudenga, Pamusoro
Saizi dziripo uye dzinokurudzirwa (DC +):
| Saizi (dhayamita mm) | 3.2 | 4.0 | 5.0 |
| Kureba (mm) | 350 | 350 | 350 |
| Range Yazvino (Amp) | 90 - 120 | 110 - 150 | 140 - 180 |
ZVINOKOSHA PAMUSORO PEKUSHANDISA:
Pisa pa300ºC zvichikwira zvakanyanya.
Shandisa PHILARC tembiricha inoratidza matanda kana PHILARC interpass tembiricha gauge kuti uone kana tembiricha yakakodzera yawanikwa usati wabatanidza.
Zvinoshanda kupisa pa600ºC uye kutonhora zvishoma nezvishoma mushure mekunamira kuti zvisatsemuke.
Omesai maerekitirodhi pa 150-200ºC kwemaminitsi 30 - 60 musati mashandisa. Shandisai maovheni ekuomesa anotakurika ePHILARC.
Yakapfuura: ECoCr-A (Cobalt 6) Cobalt Hardfacing & Welding Electrode Inodzivirira Kupfeka Zvinotevera: ENiCrFe-3 Electrodes eNickel
