GCr15 kulul oo duuban baararka wareegsan

GCr15 waa bir caam ah oo loo isticmaalo in lagu soo saaro kubbadaha iyo faraantiga xajinta. Alaabtu waxay leedahay sifooyin isku mid ah oo kiimiko ah, boqolkiiba hoose ee walxaha waxyeelada leh, nadiifinta sare, carbide si fiican loo qaybiyay, tayada sare ee wanaagsan. Waxa kale oo ay leedahay sifooyin baaxad weyn oo balaastiig ah, tayada daawaynta kulaylka deggan, labis, iyo engegnaanta sare, caabbinta xirashada sare, xoogga sare ee taabashada daalka. Waxay leedahay hanti mashiineed heer sare ah ka dib markii spheroidize annealing. GB GCr15 birta sidata waa GB heerka Alloy Bearing steel, Waxay iska leedahay kaarboon tayo sare leh, chromium alloy, birta manganese. GB GCr15 guryaha waa chromium, manganese daawaha birta qeexan. GCr15 waxay u dhigantaa AISI 52100, DIN 100Cr6. Codsiyada badankoodu way is beddeli karaan.

Daaweynta kulaylka La Xiriira

• Burburinta GCr15 Aloy sida birta

Si tartiib ah u kuleyl ilaa 790-810 ℃ una ogolow waqtiyo ku filan, u ogolow birta in si fiican loo kululeeyo, Kadibna si tartiib ah ugu qabooji foornada. Siyaabaha kala duwan ee wax u dhimi kara waxay heli doonaan qallafsanaan kala duwan. Birta sida GCr15 waxay heli doontaa Hardness MAX 248 HB (Brinell hardness).

• Deminta iyo heerkulka GCr15 Alloy birta sidata

Si tartiib ah loo kululeeyo ilaa 860°C,kadibna lagu demiyo saliid hel 62 ilaa 66 HRc adkeysi Heerkulka sare ee heerkulka: 650-700 ℃, qabow hawo, hel adkaanta 22 ilaa 30HRC. Heerkul hoose: 150-170 ℃, Qabow  in ari, hel adkaanta 61-66HRC.

• Shaqada kulul iyo shaqada qabow ee GCr15 Alloy birta

Birta GB GCr15 kulul waxay ku shaqayn kartaa 205 ilaa 538°C.

Codsiyada

GB GCr15 birta waxaa si weyn loogu isticmaalaa codsiyada kala duwan ee loo isticmaalo in lagu xidho ee mashiinada wareega. Codsiyada caadiga ah sida mashiinnada waalka, matoorada iyo qalabka ku rakiban, culeyska sare ee taayirrada, boolal, boolal laba madax leh, gears, mishiinka gubashada gudaha. Mashiinnada korantada, qalabka mishiinada, cagafyada, qalabka birta duuban, mishiinka caajiska ah, gaadiidka tareenka, iyo mishiinada gudbinta mishiinka macdanta ee kubada birta, rullaluistemadka iyo shaft sleeve, iwm.
