1.Casting karfe ball: low chromium karfe, matsakaici chromium karfe, high chromium karfe da super high chromium karfe (Cr12% -28%).
2.Forging karfe ball: low carbon gami karfe, matsakaici carbon gami karfe, high manganese karfe da rare duniya chromium molybdenum gami karfe ball:
Yanzu wane irin ƙwallon karfe ne ya fi kyau? Yanzu bari mu bincika:
1.High chromium karfe ingancin index: chromium abun ciki ne fiye da 10%, da carbon abun ciki a 1.80% -3.20% ake kira high chromium karfe, da bukatun na kasa misali high chromium ball hardness (HRC) dole ne ≥ 58, AK ≥ 3.0J/cm ƙimar tasiri na
2.Low chromium karfe ingancin index: tare da 0.5% ~ 2.5%, da carbon abun ciki a 1.80% -3.20% ake kira low chromium karfe, da bukatun na kasa misali low chromium karfe taurin (HRC) dole ne≥ 45, AK ≥ 1.5J / cm tasiri darajar 2, Rolling Ball domin tabbatar da ingancin low chromium karfe ball high zafin jiki tempering ko vibration. jiyya na tsufa (domin kawar da danniya na simintin gyare-gyare, kamar haƙiƙa) na filin ƙwallon ƙarfe yana da duhu ja don nuna cewa samfurin ya kasance babban maganin zafin jiki, kamar filin ƙwallon ƙarfe shine launin ƙarfe yana nuna samfurin ba tare da fushi ba. .
3.Forged karfe ball ingancin index: tare da 0.1% ~ 0.5% (kirgire karfe ball ba tare da chromium), da carbon abun ciki a kasa 1% da karfe ball da high zafin jiki forging masana'antu, wasu ƙirƙira karfe ball surface taurin (HRC) ≥ 56 ( ko da yake zai iya cimma fiye da quenching Layer kawai 15 mm ko makamancin haka), karfe ball saboda ƙirƙira karfe ball abu taurare ikon core taurin ne kullum kawai 30 digiri. A karkashin yanayi na al'ada, ƙirƙira ƙwallon ƙarfe ta hanyar maganin kashe ruwa, ƙirƙira ƙwallon ƙwallon karya yana da girma.
4.Comparison na lalacewa juriya: super high chromium karfe> high chromium karfe> matsakaici chromium karfe ball> low chromium karfe> ƙirƙira karfe ball.
Abubuwan ƙwallon ƙarfe mai jure lalacewa:
Abubuwan da ke cikin Chromium shine 1% - 3% da taurin HRC ≥ 45. Wannan ma'auni na ƙwallon ƙarfe mai jure lalacewa ana kiransa ƙananan ƙwallon simintin ƙarfe na chromium. Ƙananan ƙwallan chromium suna ɗaukar matsakaicin mitar wutar lantarki, ƙirar ƙarfe ko yanayin simintin yashi. Ayyukansa ya dace da wasu ma'adinan ƙarfe, slag da sauran masana'antu, waɗanda ke da ƙarancin daidaiton niƙa da ƙarancin cinyewa.
Wear-resistant karfe ball ta chromium abun ciki ne 4% zuwa 6% da taurin HRC ≥ 47. Wannan ma'auni ake kira Multi-element gami bukukuwa, wanda shi ne mafi girma fiye da low chromium karfe magana ga ƙarfi da kuma sa juriya da. Abubuwan da ke cikin Chromium shine 7% - 10% kuma taurin HRC ≥ 48 shine ƙwallan simintin simintin gyare-gyare na chromium, waɗanda aikinsu da sauran abubuwan da suke yi sun fi girman gami da ƙarfe mai tsayi.
Sawa-resistant karfe ball ta chromium abun ciki ≥ 10% - 14% da taurin HRC ≥ 58. High chromium gami simintin bukukuwa ne wani irin lalacewa-resistant karfe ball tare da high zartar kudi da kyau kudin yi a halin yanzu kasuwa. Its aikace-aikace kewayon ne fadi da kuma amfani da karfe, ciminti, thermal ikon, flue gas desulfurization, Magnetic kayan, sinadaran, kwal ruwa slurry famfo; ball saboda haka, superfine foda, slag, tashi ash, calcium carbonate da ma'adini-yashi masana'antu. Ayyukansa yana da mahimmanci musamman a cikin masana'antar siminti, wanda zai iya ƙara yawan samar da makamashi da kuma rage yawan makamashi.
