Izingxenye zemishini ezisele, izingxenye zensimbi ezimpunga
I-Grey Cast Iron inokusebenza okuhle kokuphonsa, ukujuluka okuhle, ukumelana okuhle, ukusebenza okuhle kokusika kanye nokuzwela okuphansi kwe-notch .
Izakhiwo zensimbi empunga
① imiphumela yokwakheka kwamakhemikhali . ukukhiqizwa ikakhulukazi kulawula ingxenye esezingeni eliphakeme yekhabhoni ne-silicon {{1} Lapho i-carbon ne-silicon quality fraction iphezulu kakhulu, ishidi le-graphite likhulu kakhulu futhi likhulu, futhi i-graphite entantayo ebusweni bamanzi wensimbi, ukunciphisa ukusebenza kwe-carbon kanye ne-silicon ku-grey cast iron kuvame ukulawulwa ku-2% ~ 4% c; 1 {. 0% ~ 2.0% si; I-0.5% ~ 1.4% mn.
② Ithonya lesivinini esipholile: ngaphansi kwezimo ezithile zenqubo yokuphonsa, ijubane elipholile lokuphola linomthelela omkhulu odongeni olungaphezulu, ijubane le-carbon linesikhathi esigcwele, i-athomu yokushisa inesikhathi esigcwele, izicubu zokushisa zamakamelo kulula ukwakha izicubu zensimbi; Kepha izingxenye ezincishisiwe ezibikwe ngodonga kwinqubo yokupholisa zishesha kakhulu, kulula ukwakha izicubu zensimbi ezimhlophe .
Ukwelashwa okushisa kwensimbi engwevu empunga kungashintsha kuphela inhlangano ye-matrix, hhayi ukwakheka kwe-graphix, ngakho-ke akunakwenzeka ukuthuthukisa kakhulu izindawo zokushisa zensimbi empunga kanye nokuqinisa ubulukhuni, ukuthuthukisa ubulukhuni bendawo nokugqoka
Susa ukucindezelwa kwangaphakathi
Ukuqeda ukucindezelwa okuphonsa okubangelwa ukupholisa okungalingani ngesikhathi senqubo yokuqina, futhi ukuvimba ukonakala nokuqhekeka kwenqubo yesikhathi eside, ngakho-ke i-degree yemvelo idlale isikhathi eside, le ndlela ibiza ngokuthi "le ndlela ibizwa nge-" Le ndlela ibizwa ngokuthi "yimvelo ukuguga ", i-iron enkulu engwevu empunga ingathatha le ndlela ukuqeda ukucindezelwa okuphonsa [4] .
Ukuqhafaza okuvela eceleni
Ukuze uqede izicubu zomlomo ezimhlophe, zehlisa ubulukhuni, uthuthukise ukusebenza kokusika
Icala liqinisa
Thuthukisa ubulukhuni obungaphezulu futhi unwebe impilo yensiza . ngokwesibonelo, indawo esebenzayo yodonga lomshini we-cylinder umkhono we-cylinder umkhono we-cylinder sleeve we-cylinder sleenes ye-cylinder sleeve ye-cylinder ({1}} Izindlela ezijwayelekile zokufudumeza (okuphakathi nendawo) ukuguda
Amashadi ashisayo: Izingxenye zemishini, izingxenye zensimbi ezimpunga, izingxenye ze-China Mechanical Spare, abakhiqizi be-Iron-cast-cast izingxenye, abahlinzeki, ifektri
