| Ukukhethwa kwezinto eziqhelekileyo zokuphosa | |
| Izinto eziphathekayo | Iimpawu kunye nezicelo |
| Grey cast iron | Ubumanzi obulungileyo, isantya esincinci sokucutheka ngexesha lokupholisa, amandla aphantsi, iplastiki kunye nokuqina, imodyuli elastiki iyahluka phakathi kwe-80000 ~ 140000MPa kunye ne-microstructures ezahlukeneyo, amandla acinezelayo ngama-3 ~ 4 amaxesha aphezulu kunamandla okuqina, ukumelana nokunxibaukusebenza kunye nokufunxa ukungcangcazela.Ayinabungozi ekusikeni kwaye inomsebenzi olungileyo wokusika.Ukusebenza kwe-welding kumbi.Ayinakusetyenziswa ixesha elide ngaphezu kwe-300 ~ 400℃.I-85% ~ 90% izinga lemveliso yentsimbi. |
| Mintsimbi ethambileyo | Ukusebenza kwentsimbi kubi ngakumbi kuneyentsimbi engwevu kwaye ingcono kuneyentsimbi.Isetyenziselwa ukwenza iicastings ezincinci ezinodonga oluncinci ezineemfuno ezithile zokuqina kunye nokuqina.Ukuxhathisa okulungileyo kokubola kunye nokusebenza kakuhle kokusebenza.Ukuqina kwempembelelo yi-3 ~ 4 amaxesha amakhulu kune-grey cast iron. |
| Intsimbi yentsimbi | Ukusebenza kwentsimbi kubi kakhulu kunokwentsimbi engwevu, kwaye ithande ukuba neziphene.Ukusebenza kokusika kulungile, kwaye unyango lobushushu lunokwenza utshintsho lwalo kuluhlu olubanzi.Amandla okuqina angaphezulu kunalawo entsimbi etyhidiweyo kunye nentsimbi ephosiweyo, kwaye umlinganiselo wamandla esivuno ukuya kumandla okuqina uphezulu kunentsimbi etyhidiweyo kunye nentsimbi.Iplastiki yeyona igqwesileyo kwintsimbi etyhidiweyo, kwaye ukuqina kwempembelelo ayilunganga njengentsimbi, kodwa inkulu kakhulu kuneyentsimbi engwevu.Inokusebenza kakuhle kobushushu obuphantsi.Amandla okukhathala aphezulu, kufutshane nentsimbi ye-45, kodwa uvakalelo lokuxinzelela uxinzelelo lungaphantsi kunelo lwentsimbi.Ukumelana nokunxiba kakuhle, ukumelana nobushushu kunye nokumelana nokugqwala.I-vibration attenuation ratio yentsimbi, i-ductile iron kunye ne-grey iron yi-1: 1.8: 4.3.isetyenziswa ngokubanzi njengamalungu abalulekileyo. |
| Intsimbi yeGrafite eQaniweyo | Iimpawu zomatshini ze-vermicular graphite cast iron cast ziphakathi kwentsimbi engwevu kunye ne-ductile iron, kwaye inokuqina okuhle, ukumelana nobushushu kunye nokumelana nokunxiba.Ukusebenza kwayo kubhetele kune-ductile iron kwaye isondele kuleyo yentsimbi engwevu.Amandla ayo afana nentsimbi ye-ductile, kwaye ine-anti-vibration efanayo, i-thermal conductivity kunye neempawu zokuphosa kwi-iron grey, kodwa iplastiki engcono kunye nokumelana nokukhathala kunentsimbi engwevu.I-iron edibeneyo ye-graphite cast iron ngokuqinisekileyo iya kuba nenani elithile le-nodular graphite.Ukunyuka kwe-graphite ye-nodular kuya kwandisa amandla kunye nokuqina, kodwa ngeendleko zokuphazamisa ikhono lokuphosa lentsimbi etyhidiweyo kunye nokuwohloka kokusebenza kunye nokuhanjiswa kwe-thermal of castings. |
| intsimbi | Ukusebenza kwe-casting kumbi kakhulu, i-fluidity ihlwempuzekile, kwaye ukucutheka kukhulu, kodwa kuneempawu eziphezulu ezibanzi zoomatshini, oko kukuthi, amandla aphezulu, ukuqina kunye neplastiki.Amandla okuqina kunye namandla acinezelayo aphantse alingane.Ezinye iintsimbi eziphosiweyo ezikhethekileyo zineempawu ezikhethekileyo ezifana nokumelana nobushushu kunye nokumelana nokubola |
| Yenza ingxube ye-aluminium | I-alloys ye-aluminiyam yi-1/3 kuphela yobuninzi bentsimbi kwaye isetyenziselwa ukwenza izakhiwo ezahlukeneyo zokukhanya.Ezinye ii-alloys ze-aluminiyam zinokomelezwa ngonyango lobushushu ukuze zibe neempawu ezibanzi ezingcono.Njengoko ubukhulu bodonga bukhula, amandla ayancipha kakhulu. |
| ubhedu olutyhidiweyo | Yahlulahlulwe yangamacandelo amabini: ubhedu lwetin kunye ne-Wuxi bronze.Ubhedu lwe-tin lunxibe kakuhle kunye nokumelana nokubola, ukomelela okuphezulu kunye nokuqina, ukusebenza kakubi kokuphosa, kwaye kulula ukuhlukana kunye nokushwabana.Ukucima akunasiphumo someleza.Ubhedu lwe-Wuxi luqhele ukusetyenziswa kwibronzi ye-aluminiyam okanye ubhedu olukhokelayo, olunokusebenza kakubi.I-Aluminiyam yobhedu inamandla aphezulu, ukumelana nokunxiba kunye nokuxhathisa ukubola.Ubhedu olukhokelayo lunamandla aphezulu okudinwa, ukuguquguquka okuqinileyo kwe-thermal kunye nokumelana ne-asidi |
| Phosa ubhedu | Ukuncipha okukhulu, ukomelela okuphezulu ngokubanzi, iplastikhi elungileyo, ukuxhathisa okulungileyo kokutya kunye nokunganyangeki.Ukusebenza kakuhle kokusika |
