Ithonya Lokungcola Ezakhiweni Zensimbi

Ngaphezu kwensimbi, i-carbon ne-alloy element, okunye ukungcola (okufana ne-manganese, i-silicon, isulfure, i-phosphorus, ukungcola okungasensimbi namanye amagesi, njenge-nitrogen, i-hydrogen, i-oxygen, njll.) kwinqubo yokuncibilikisa. Lokhu kungcola kunomthelela omkhulu kwikhwalithi yensimbi.

• Lapho i-manganese ikhona njengokungcola kwensimbi, imvamisa iba ngaphansi kuka-0.8%. Kuvela kwinsimbi yengulube ne-deoxidizer ferromanganese njengezinto zokusetshenziswa zokwenza insimbi. IManganese inekhono elihle lokususa i-deoxidation futhi ingakha i-MNS ngesulfure ukuqeda imiphumela eyingozi yesibabule. Iningi lale mikhiqizo yokuphendula ingena ku-slag futhi iyasuswa, bese kuthi ingxenye encane ihlale kusimbi bese iba yizinto ezingezona ezensimbi. Ngaphezu kwalokho, i-manganese ingaqedwa nge-ferrite ekamelweni lokushisa, elinomphumela othile wokuqinisa insimbi. I-Manganese nayo ingahlakazwa ku-cementite ukwakha i-alloy cementite. Kodwa-ke, lapho ama-manganese akhona njengokungcola okuncane, umphumela wawo kuzakhiwo zensimbi awubalulekile.
• Lapho i-silicon ikhona njengokungcola kwensimbi, imvamisa iba ngaphansi kuka-0.4%. Kubuya nakwinsimbi yengulube ne-deoxidizer. Ekamelweni lokushisa, i-silicon ingahlakazeka ku-ferrite futhi inomphumela othile wokuqinisa insimbi. Kodwa-ke, lapho i-silicon ikhona njengenani elincane lokungcola, umphumela wayo kuzakhiwo zensimbi awubalulekile.
• Isibabule ukungcola okulethwa ngensimbi yensimbi yengulube nophethiloli. Esimweni esiqinile, ukuncibilika kwesibabule ensimbi kuncane kakhulu, kepha kutholakala ngendlela ye-FES ngensimbi. Ngenxa yobupulasitiki obumpofu be-FES, insimbi enesibabule eningi iyabhidlika. Ngaphezu kwalokho, i-FES neFe bangakha i-eutectic enendawo ephansi yokuncibilika (985 ℃) futhi basabalalise emngceleni wokusanhlamvu we-austenite. Lapho insimbi ifutheliswa cishe ku-1200 ℃ ukucutshungulwa kwengcindezi eshisayo, i-eutectic emngceleni wezinhlamvu incibilikile futhi ukubopha phakathi kwezinhlamvu kuyabhujiswa, okwenza insimbi iqhekeze umngcele wokusanhlamvu ngesikhathi sokucubungula. Lesi simo sibizwa ngokuthi yi-hot brittleness. Ukuze uqede umphumela olimazayo wesibabule, okuqukethwe kwe-manganese ngensimbi kufanele kukhuphuke. I-Manganese nesibabule bakhetha i-manganese sulfide enezinga eliphakeme lokuncibilika (1620 ℃) ​​bese besabalalisa okusanhlamvu ngendlela eyimbudumbudu. Inempahla ethile yokubumba ekushiseni okuphezulu, ngaleyo ndlela igwema ukuqina okushisayo. I-Sulfide uhlobo lokufakwa okungekhona okwensimbi, olunganciphisa izakhiwo zemishini zensimbi futhi lwenze isakhiwo esishisayo se-fiber ngesikhathi sokugingqika. Ngakho-ke, isulfure imvamisa kungukungcola okuyingozi. Okuqukethwe kwesibabule ngensimbi kufanele kukhawulelwe ngokuqinile. Kepha insimbi enokuqukethwe kwesibabule okuningi ingakha ama-MNS amaningi. Enkambeni yokusika, i-MNS ingadlala indima yokuqhekeka kwe-chip futhi ithuthukise ukusebenza kwensimbi, okuyihlangothi elihle lesibabule.
• I-Phosphorus ithwalwa ngensimbi yensimbi yengulube. Ngokuvamile, yonke i-phosphorus ngensimbi ingaqedwa nge-ferrite. I-Phosphorus inomphumela oqinile wokuqinisa isisombululo, okwandisa amandla nobulukhuni bensimbi, kepha kwehlisa ubukhulu beplastiki nobulukhuni. Lokhu kungenelela kubucayi kakhulu emazingeni okushisa aphansi, ngakho-ke kubizwa ngokuthi ukubanda okubandayo. Ngokuvamile, kulindeleke ukuthi ukushisa okuguqukayo kokubandayo okubandayo kungaphansi kunokushisa okusebenzayo kwendawo yokusebenza ukuze kugwenywe ukubanda okubandayo. Ngesikhathi senqubo ye-crystallization ye-phosphorus, kulula ukukhiqiza ukuhlukaniswa kwe-intragranular, okwenza okuqukethwe kwe-phosphorus kwezinye izindawo kuphakame, okuholele ekwandeni kokushisa okubandayo okuguqukayo, okuholele ekubandeni okubandayo. Ukufakwa okubandayo kuyingozi ezingxenyeni zesakhiwo ezisebenza endaweni ebanda kakhulu nakwezinye izimo zokushisa eziphansi. Ngaphezu kwalokho, ukuhlukaniswa kwe-phosphorus nakho kwenza ifomu lensimbi liboshwe ngesakhiwo ngemuva kokugingqika okushisayo. Ngakho-ke, ngokuvamile, i-phosphorus nayo ingukungcola okuyingozi. Okuqukethwe kwe-phosphorus ngensimbi kufanele futhi kulawulwe ngokuqinile. Kodwa-ke, lapho okuqukethwe kwe-phosphorus kuphezulu, ukuqina kwensimbi yegobolondo kuphezulu, ngakho-ke kunenzuzo yokwenza insimbi yegobolondo nokwenza ngcono ukusebenza kwensimbi.
• Ukufakwa okungekona kwensimbi ngenkathi kwenziwa insimbi, inani elincane le-slag, imikhiqizo ye-refractory kanye ne-reaction ingangena ensimbi ewuketshezi bese yakha okungafaki okusansimbi. Isibonelo, ama-oxide, ama-sulfide, ama-silicates, ama-nitride, njll. Zizonciphisa izakhiwo zensimbi, ikakhulukazi ubukhulu beplastiki, ukuqina nokukhathala. Uma kungathi sína, kuzokwenza ukuqhekeka kwensimbi ngesikhathi sokwelapha okushisayo nokwelashwa kokushisa noma ukuphuka kabuhlungu kungazelelwe. Ukufakwa okungekhona okwensimbi nakho kukhuthaza ukwakheka kwesakhiwo esishisayo se-fiber nesakhiwo esiboshiwe, okwenza into i-anisotropic. Ezimweni ezimbi kakhulu, i-plasticity eguqukayo iyingxenye kuphela ye-longitudinal, futhi ubunzima bethonya bancipha kakhulu. Ngakho-ke, inombolo, ukwakheka, usayizi nokusatshalaliswa kokufakwa okungekhona okwensimbi kufanele kuhlolwe insimbi ebalulekile (njengokugoqa insimbi ethwele, insimbi yasentwasahlobo, njll.). Ngaphezu kwalokho, phakathi nayo yonke inqubo yokuncibilikisa insimbi, insimbi ihlangana nomoya, ngakho-ke amanye amagesi afana ne-nitrogen, i-oxygen ne-hydrogen ahlala amunwa yinsimbi engamanzi. Futhi zinomphumela omubi kwikhwalithi yensimbi.

Sicela ugcine umthombo nekheli lale ndatshana ukuze uphinde uprintwe:Ithonya Lokungcola Ezakhiweni Zensimbi

UMinghe Inkampani yeDie Casting anikezelwe ekukhiqizeni nasekuhlinzekeni ikhwalithi nokusebenza okuphezulu Izingxenye Zokulingisa (izingxenye zensimbi zensimbi zokufa zisebenza ikakhulukazi zibandakanya I-Thin-Wall Die Casting,I-Hot Chamber Die Casting,Cold Chamber die Casting), Insizakalo Eyindilinga (Insiza Yokulingisa,ICnc Machining,Ukwenza Okubandayo, Surface Treatment) .Noma ikuphi ukusakazwa kwe-Aluminium die, i-magnesium noma i-Zamak / zinc die casting nezinye izidingo zokuphosa zamukelekile ukuxhumana nathi.

Ngaphansi kokulawulwa kwe-ISO9001 ne-TS 16949, Zonke izinqubo zenziwa ngamakhulu emishini esezingeni eliphakeme yokufa, imishini ye-5-axis, nezinye izikhungo, ezisukela kuma-blasters kuya kumishini yokuwasha ye-Ultra Sonic.Minghe akagcinanga ngemishini esezingeni eliphezulu kepha futhi unobuchwepheshe iqembu lonjiniyela abanolwazi, ama-opharetha nabahloli ukwenza ukwakheka kwekhasimende kugcwaliseke.

Umenzi wenkontileka yokufa kwabasikiwe. Amandla afaka izingxenye ezibandayo ze-aluminium die casting ezivela ku-0.15 lbs. kuye ku-6 lbs., Ukusetha ushintsho olusheshayo, nemishini.
