1. Ibhola lensimbi elibunjiwe: insimbi ephansi ye-chromium, insimbi ye-chromium ephakathi, insimbi ye-chromium ephezulu kanye nensimbi ye-chromium ephezulu kakhulu (Cr12%-28%).
2. Ibhola lensimbi elenziwe nge-Forging: insimbi ye-alloy ephansi yekhabhoni, insimbi ye-alloy ephansi yekhabhoni, insimbi ye-manganese ephezulu kanye nebhola lensimbi ye-chromium molybdenum alloy engavamile yomhlaba:
Manje yiluphi uhlobo lwebhola lensimbi olungcono kakhulu? Manje ake sihlaziye:
1. Inkomba yekhwalithi yensimbi ye-chromium ephezulu: okuqukethwe kwe-chromium kungaphezu kuka-10%, okuqukethwe kwekhabhoni ku-1.80%-3.20% kubizwa ngokuthi insimbi ye-chromium ephezulu, izidingo zezinga likazwelonke lokuqina kwebhola le-chromium ephezulu (HRC) kumele zibe ngu-≥ 58, AK ≥ 3.0J/ cm inani lomthelela we
2. Inkomba yekhwalithi yensimbi ye-chromium ephansi: ngo-0.5% ~ 2.5%, okuqukethwe kwekhabhoni ku-1.80% -3.20% kubizwa ngokuthi insimbi ye-chromium ephansi, izidingo zobunzima bensimbi ye-chromium ephansi (HRC) ejwayelekile kazwelonke kumele zibe ngu-≥ 45, AK ≥ 1.5J/cm inani lomthelela we-2, Ibhola Eligoqekayo ukuqinisekisa ikhwalithi yebhola lensimbi ye-chromium ephansi, ukushisa okuphezulu noma ukwelashwa kokuguga kokudlidliza (ukuze kuqedwe ukucindezeleka kokuphonswa, njengenhloso) yebhola lensimbi elingaphezulu libomvu ngokumnyama ukukhombisa ukuthi umkhiqizo ube ukwelashwa kokushisa okuphezulu, njengokuthi ubuso bebhola lensimbi umbala wensimbi ubonisa umkhiqizo ngaphandle kokushisa.
3. Inkomba yekhwalithi yebhola lensimbi eyakhiwe: ene-0.1% ~ 0.5% (ibhola lensimbi eyakhiwe ngaphandle kwe-chromium), okuqukethwe kwekhabhoni okungaphansi kuka-1% kanye nebhola lensimbi elinokukhiqiza okuphezulu kokushisa, ubulukhuni obuthile bomphezulu webhola lensimbi eyakhiwe (HRC) ≥ 56 (yize ingafinyelela okungaphezu kongqimba lokucima ungqimba oluyi-15 mm noma ngaphezulu), ubulukhuni bebhola lensimbi ngenxa yezinto zensimbi eyakhiwe buvame ukuba ngama-degrees angu-30 kuphela. Ngaphansi kwezimo ezijwayelekile, ibhola lensimbi eyakhiwe ngokwelashwa kokucima amanzi, izinga lokuphazamiseka kwebhola lensimbi eyakhiwe liphezulu.
4. Ukuqhathaniswa kokumelana nokuguguleka: insimbi ye-chromium ephezulu kakhulu > insimbi ye-chromium ephezulu > ibhola lensimbi ye-chromium ephakathi > insimbi ye-chromium ephansi > ibhola lensimbi elihlanganisiwe.
Izinto zebhola lensimbi elingagugi:
Okuqukethwe kwe-Chromium kungu-1% - 3% kanti ubulukhuni be-HRC ≥ 45. Leli zinga lebhola lensimbi elingagugi libizwa ngokuthi ibhola eliyi-low chromium alloy cast. Amabhola e-chromium aphansi asebenzisa imodi ye-electrical furnace ephakathi nendawo, i-metal mold noma i-sand casting. Ukusebenza kwayo kufanelekile kwezinye izimayini ze-metallurgical, i-slag kanye nezinye izimboni, ezinokunemba okuphansi kokugaya kanye nokusetshenziswa okuphansi.
Okuqukethwe kwe-chromium yebhola lensimbi elingagugi kungu-4% kuya ku-6% kanye nobunzima be-HRC ≥ 47. Leli zinga libizwa ngokuthi amabhola e-alloy e-multi-element, aphezulu kunensimbi ye-chromium ephansi ebhekisela emandleni kanye nokumelana nokuguguleka. Okuqukethwe kwe-Chromium kungu-7% - 10% kanti ubunzima be-HRC ≥ 48 bungamabhola e-chromium alloy cast, okusebenza kwawo nezinye izici kuphakeme kunebhola lensimbi ye-alloy e-multiple alloy.
Okuqukethwe kwe-chromium yebhola lensimbi elingagugi ≥ 10% – 14% kanye nobunzima be-HRC ≥ 58. Amabhola e-chromium alloy cast aphezulu uhlobo lwebhola lensimbi elingagugi elinesilinganiso esiphezulu esisebenzayo kanye nokusebenza kahle kwezindleko emakethe yamanje. Uhla lokusetshenziswa kwalo lubanzi futhi lusetshenziswa ekubumbeni izinsimbi, usimende, amandla okushisa, ukukhishwa kwegesi ye-flue, izinto zikagesi, amakhemikhali, ipompo yokulunywa kwamanzi amalahle; ngakho-ke ibhola, impuphu ecolekile, i-slag, umlotha wempukane, i-calcium carbonate kanye nemboni yesihlabathi se-quartz. Umsebenzi walo ugqanyisiwe ikakhulukazi embonini yesimende, engakhuphula ukukhiqizwa futhi inciphise ukusetshenziswa kwamandla.
