Umehluko phakathi kokuphonsa ibhola lensimbi kanye nokwakha ibhola lensimbi

I-1.acasting ibhola lensimbi: i-chromium ephansi, insimbi ye-chromium ephakathi, i-chromium steel ephezulu ne-super high high chromium steel (CR12% -28%).

2.rging ibhola lensimbi

Manje yiluphi uhlobo lwebhola lensimbi oluhamba phambili? Manje ake sihlaziye:

I-1.High Chromium Steel Ikhwalithi Yezinga: Okuqukethwe kwe-chromium kungaphezulu kwe-10%, okuqukethwe yi-carbon ku-1.80% -3.20% kubizwa ngenani le-chromium ephezulu ye-chromium (HRC) kumele kube yinani le-≥ 58, ak 3.0 / cm

2.low i-chromium yensimbi yekhwalithi yekhwalithi: nge-0.5% ~ 2.5%, okuqukethwe yi-carbon ku-1.80% -3.20% inani le-chromium lensimbi eliphansi, ukuqhafaza ibhola eliphansi lokushisa i-chromium ibhola lokushisa le-chromium Ingcindezi, efana nenhloso) yensimbi yensimbi ebomvu emnyama ukukhombisa ukuthi umkhiqizo ube yindlela yokushisa ephezulu yokushisa, efana nensimbi yensimbi yombala wensimbi ikhombisa umkhiqizo ngaphandle komoya obonisa umkhiqizo ngaphandle komoya.

3.Ngokwakhiwa ikhwalithi yekhwalithi yensimbi Ngaphansi kwezimo ezijwayelekile, ibhola lensimbi elenziwe ngomuthi ocimisa amanzi, inani lensimbi yensimbi ephukile liphezulu.

I--4.comRarison of Ukumelana Nezinto Eziphakeme

Izinto zensimbi evimbela insimbi engazweli:

Okuqukethwe kwe-chromium kungu-1% - 3% kanye nobulukhuni HRC ≥ 45. Leli Zinga lebhola elivimbela insimbi yokugqoka libizwa nge-chromium alloy cast ibhola. Amabhola we-chromium aphansi amukela imvamisa kagesi ephakathi nendawo, isikhunta sensimbi noma imodi yokusakaza isihlabathi. Ukusebenza kwayo kulungele izimayini ezithile zensimbi, i-slag kanye nezinye izimboni, ezinokunemba okuphansi nokudla okuphansi.

Okuqukethwe kwensimbi yensimbi engavikeli ukugqoka kungu-4% kuya ku-6% no-Hardness Hrc ≥ 47. Leli Zinga libizwa ngokuthi amabhola we-multi-element, okuphezulu kwensimbi ephansi ebhekisa emandleni nasekugqokeni ukumelana futhi. Okuqukethwe kwe-chromium kungu-7% - 10% kanye nobulukhuni HRC ≥ 48 amabhola we-chromium alloy aphonsa amabhola, okusebenza kwawo nezinye izici eziphakeme kune-alloy steel ephezulu ephezulu.

Okuqukethwe kwensimbi evinjelwe kwensimbi ye-chromium ≥ 10% - 14% nobulukhuni HRC ≥ 58 Uhla lwalo lwesicelo lubanzi futhi lusetshenziselwa i-metallurgy, usimende, amandla we-thermal, ukuphelelwa yigesi kwe-flue, impahla kazibuthe, iphampu yamanzi, amakhemikhali, amakhemikhali amanzi athambile; Ngakho-ke, ibhola le-superfine powder, i-slag, i-fly ash, calcium carbonate kanye nomkhakha wesihlabathi we-quartz. Umsebenzi wayo uqokonyiswe ikakhulukazi embonini yensimbi, engakhuphula ukukhiqizwa nokunciphisa ukusetshenziswa kwamandla.
