Kusiyana pakati pa mpira wachitsulo ndikusiya mpira wachitsulo

Kutentha kwachitsulo: Chitsulo chotsika cha chromium, chapamwamba chromium steum, chisanu chachikulu cha chromium ndi super chromium snomium snomium (CR12% -28%).

2.Foning Steel Mpira: Wotsika kaboni tentholo, kaboni kaboni chitsulo, chitsulo chachikulu cha manganese ndi chozungulira pansi chremium

Tsopano ndi mtundu wanji wa mpira wabwino kwambiri? Tsopano tiyeni tisanthule:

1.High chromium steel Index: Chromium zomwe zilipo 10%, zokhudzana ndi mpweya mu 1.80% -3.20% amatchedwa phlemium mpira wa chromium (HRC) iyenera kukhala yabwino kwambiri

2.ow chromium steum index; .

3.Fent steel mpira wabwino: ndi 0.1% ~ 0.5% (Stear) Yopanda Zachitsulo (HRC) madigiri. Nthawi zambiri amakhala ndi mpira wachitsulo ndi mafuta owuzira madzi, kuchuluka kwa khola losweka ndi lalitali.

4.COMMARING OGING Kukana: Super Chromium snomium steel> Chromium snomium steel> sing'anga chromium snoel mpira> Chromium Steels.

Zinthu za mpira wowonongeka kwambiri:

Chromium zomwe zili ndi 1% - 3% ndi kuuma kwa HRC ≥ 45. Muyezo wocheperako wachitsulo umatchedwa chromiamu stofi. Mipira yotsika yotsika ya chromium imatengera ntchentche yoyaka ikuluikulu, chitsulo chazitsulo kapena mchenga. Kuchita kwake ndi koyenera kwa migodi ina yachitsulo, slag ndi mafakitale ena, omwe amachepetsa kufoka kolondola komanso kuwononga pang'ono.

Zovala zosalimba za mpira ndi 4% mpaka 6% ndi kulimbika hrc ≥ 47. Muyezo uwu umatchedwa mipira yambiri, yomwe ndi yapamwamba kwambiri ya chromium yomwe ikutanthauza kulimba mtima komanso. Chromium zomwe zili ndi 7% - 10% ndi kuuma kwa HRC ≥ 48 ndi chromium alloy amaponya mipira, yomwe magwiridwe ake ndi ena apamwamba kuposa alloy.

Vorium yolimbana ndi Chromium ya mpira ≥ 10% - 14% ndi kuuma kwa HRC ≥ 58. Mitundu yake ili ndi yambiri ndipo imagwiritsidwa ntchito ku metalliggy, simenti, mphamvu yamafuta, mafuta osungunuka, pampu yamadzi, madzi am'madzi olerera; Mpira Chifukwa chake, ufa superfine, slag, kuuluka phulusa, calcium carbonate ndi mafakitale a Quartz. Ntchito yake imafotokozedwa makamaka mu makampani a simenti, omwe amatha kuwonjezera kupanga ndikuchepetsa kugwiritsa ntchito mphamvu.
