Ukusakaza centrifugal - indlela yokuthola izikhala olunembile

Ukusakaza centrifugal - indlela yokukhiqiza izikhala Castings, ogxile imiphumela force centrifugal phezu mass esincibilikisiwe impahla. Foundry, waziphatha womshini izikhala okwenyanga futhi Castings anolaka, has ezihlukahlukene izindlela ekubunjweni: hlala, e isikhunta esihlabathini-ubumba, emakhilayoni ekubunjweni ekhethekile, ngaphansi kwengcindezi, njll Kodwa izinga etholwe asakazwe elilungile liphakathi asakazwe centrifugal.

Empeleni, indlela olugxile ukuthi ngenkani centrifugal okokusebenza oncibilikisiwe nombala sisakazeka ebusweni engaphakathi isikhunta namafomu crystallizing elingenalutho nge imingcele edingekayo. Ungacabangi ukuthi le ndlela isebenza izinsimbi kanye Alloys yabo kuphela. Eqinisweni, ekubunjweni imikhiqizo yepulasitiki busakazeke ngokungavamile. Kodwa amapulasitiki benezingane eziningi izici ezidinga kubhekwe uma usebenza nabo. Injection Plastic ngokuvamile eyenziwa ngaphansi kwengcindezi, esinikela imikhiqizo ezikhethekile ukunemba.

Ezimweni eziningi, izinhlobo ezahlukene ekusakazeni zisetshenziselwa ukukhiqiza metal Castings. Ngakho, ekubunjweni centrifugal kunezinzuzo eziningana :. Ayikho voids nomgodi slag inclusions ku okuholela yabalingisi, Isidlulisilwazi impahla, kukhuphuke bafake metal ukumelana, okuyinto ibangelwa isakhiwo iyunifomu, njll Izinzuzo esemqoka le ndlela zibizwa ngokuthi ukonga okwalotshwa workpiece kanye nokwehla okuphawulekayo yinkimbinkimbi yonke inqubo inqubo (ngenxa isilinganiselo maximal isakaza umkhiqizo osuphelile).

Ukusakaza centrifugal enezinto eziningi "lokususa". Lezi zihlanganisa: ukuthola olungalungile evele mahhala workpiece, ukuthambekela sengeta amafomu ngokwahlukana impahla zibiza (ngenxa nezidingo anda ukunemba ntathu).

imishini Special asetshenziswa centrifugal asakazwe indlela. Ziyahlukahluka bebheke eksisi ujikeleza - mpo, ovundlile futhi ithambekele-eksisi (iqiniso, kudala kuyaqabukela esetshenziswa). Imishini kanye eksisi eqonde ngqo phezulu ezisetshenziswa emasimini ukukhiqiza ukudla encane sobude amalunga nomehluko omncane izinyathelo (amasongo, pistons, emikhonweni nokunye okunjalo). Imishini nge eksisi evundla ujikeleza avumele ukuthola eside sobude ephezulu ukucacisa Castings nge ukushuba odongeni eyodwa. Ngokufanayo ezihlelwa indlela sensimbi amapayipi. Le ndlela iyona ezivamile. Ukusebenzisa asakazwe centrifugal angakhiqiza amapayipi nge izindonga 80 300 mm (kuye ngokuthi imishini esetshenziswa). Into kuphela ukuthi kufanele nakanjani akhumbule yokuthi ngale ndlela, ukucindezeleka yangaphakathi kwenzeka izikhala. Ngakho-ke, ngemva kokuthola Castings ezidingekayo ukuqhuba annealing.

centrifugal ekubunjweni indlela futhi sikulungele kwezinye izingxenye preform, okuyinto bakha umzimba zokuvukela umbuso. Ethandwa kakhulu ukucacisa asakazwe indlela isetshenziswa ekukhiqizeni amalunga kusukela izinsimbi non-ayoni (le ndlela ikuvumela ukuba ugcine izinto ezibizayo).
