Isihloko: Ukuqonda ukusebenza kwe-ai-vacuum caster enezingqimbangezinsimbi eziyigugu nama-alloys

Ukusetshenziswa kobuchwepheshe obuthuthukisiwe kubalulekile lapho kukhiqizwa izinsimbi eziyigugu nama-alloys ekhwalithi ephezulu. Umshini wokuphonsa ovundlile we-vacuum uwubuchwepheshe obushintsha ngokuphelele inqubo yokukhiqiza. Le mishini emisha idlala indima ebalulekile ekukhiqizeni izinsimbi ezihlukahlukene eziyigugu nama-alloys, iletha ikhwalithi engavamile nokusebenza kahle. Kule bhulogi, sizocubungula ukusebenza okuyinkimbinkimbi kwe-vacuum eqhubekayo ye-vacuum, sihlole ukusebenza kwayo kanye nezinqubo ezibalulekile ezihilelekile ekukhiqizeni izinsimbi eziyigugu nama-alloys.

Ukusebenza kokuvundlilevacuum okuqhubekayo umshini wokuphonsaiqala ngokulungiswa kwezinto zokusetshenziswa. Izinsimbi eziyigugu nama-alloys akhethwe ngokucophelela futhi alungiselelwe inqubo yokuphonsa. Izinto zokusetshenziswa zincibilika esithandweni sokushisa okuphezulu ukuze zifinyelele esimweni esilungile soketshezi ukuze kuphonswe. Lapho insimbi encibilikisiwe ifinyelela izinga lokushisa nokuvumelana okufunayo, ingadluliselwa egumbini lokuphonsa lomshini.

Lapho insimbi encibilikisiwe yethulwa ekamelweni lokuphonsa, indawo ye-vacuum idlala indima ebalulekile ekuqinisekiseni ikhwalithi yenqubo yokuphonsa. Ukungabikho komoya nokunye ukungcola ekamelweni le-vacuum kusiza ukuvimbela i-oxidation kanye nokungcoliswa kwensimbi encibilikisiwe, okuholela kumkhiqizo wokugcina wekhwalithi ephezulu. Le ndawo ye-vacuum iphinde ivumele ukulawula okungcono kwenqubo yokupholisa, okuvumela ukukhiqizwa kokusakazwa okunembayo nokufana okufanayo.

Igumbi lokuthulula lomshini wokudonsa ovundlile we-vacuum eqhubekayo ifakwe uchungechunge lwezindlela zokupholisa ezinembayo. Lezi zindlela zenzelwe ukupholisa insimbi encibilikisiwe ngokushesha njengoba idlula ekamelweni, ngaleyo ndlela ikhuthaze inqubo yokuqinisa. Ngokulawula izinga lokupholisa, umshini ungakhiqiza ama-castings anezici ezithile ze-metallurgical, ukuqinisekisa izici ezifiselekayo zomkhiqizo wokugcina.

Esinye sezici eziyinhloko ze-vacuum evundlile eqhubekayo yikhono lokukhiqiza ukulingisa okude kobude obuqhubekayo. Ngokungafani nezindlela zendabuko zokulingisa lapho ubude bokuphonsa bungakhawulelwa, ama-vacuum caster avundlile angakhiqiza ubude obude bensimbi ekhonjiwe. Leli khono liwusizo ikakhulukazi ekukhiqizeni izinsimbi eziyigugu kanye nemikhiqizo ye-alloy, evame ukudinga ukukhishwa okude, okufanayo ukuze kuqhutshekwe nokukhiqizwa nokukhiqizwa.

Ukulawula okunembile kwejubane lokuphonsa kungenye ingxenye ebalulekile yokusebenza komshini. Ngokulawula isivinini sensimbi encibilikisiwe ngegumbi lokuphonsa, abakhiqizi bangakwazi ukufeza usayizi ofunwayo wokuphonsa kanye nezakhiwo. Leli zinga lokulawula libalulekile ekukhiqizeni izinsimbi eziyigugu zekhwalithi ephezulu kanye nemikhiqizo ye-alloy, lapho ukunemba kobukhulu kanye nokuvumelana kubalulekile.

Ngaphezu kwenqubo yokusakaza ngokwayo, i-vacuum continuous caster evundlile isebenzisa izinhlelo ezithuthukisiwe zokuqapha nokulawula. Lezi zinhlelo zivumela opharetha ukuthi baqaphe ngokucophelela amapharamitha ahlukahlukene wenqubo yokuphonsa, okuhlanganisa izinga lokushisa, izinga lokupholisa kanye nesivinini sokusakaza. Ngokuqhubeka nokuqapha nokulungisa le mingcele, abakhiqizi bangaqinisekisa ikhwalithi yokusakazwa engaguquki ehlangabezana nezidingo eziqinile zezinsimbi eziyigugu nokukhiqizwa kwengxubevange.

Umshini wokukhipha i-vacuum ovundlile oqhubekayo nawo ufakwe izindlela ezithuthukisiwe zokukhipha kanye nezindlela zokusika. Lapho insimbi encibilikisiwe iqina ibe ukubunjwa okuqhubekayo, imishini ingakhipha ukwakheka kwegumbi ngokunembile futhi isike ibe ubude obudingekayo. Le nqubo ezenzakalelayo iqinisekisa ukukhiqizwa okuphumelelayo kokulingisa okufanayo, okusezingeni eliphezulu okulungele ukuqhutshekiselwa phambili nokukhiqizwa.

Ukuguquguquka kwama-vacuum casters avundlile kuwenza alungele ukukhiqizwa kwezinhlobonhlobo zezinsimbi eziyigugu nama-alloys. Kungakhathaliseki ukuthi igolide, isiliva, iplatinamu noma ama-alloys akhethekile, umshini ungakwazi ukuzivumelanisa nezinto ezihlukahlukene futhi ukhiqize ukulingisa ngokunemba okukhethekile nokuvumelana. Lokhu kuvumelana nezimo kubalulekile ukuze kuhlangatshezwane nezidingo ezihlukahlukene zezimboni ezithembele ezinsimbi eziyigugu zekhwalithi ephezulu kanye nemikhiqizo ye-alloy.

Kafushane, ukusebenza kwe-vacuum evundlile eqhubekayo yensimbi eyigugu nama-alloys kuhilela uchungechunge lwezinqubo eziyinkimbinkimbi ezihlelwe ngokucophelela ukuze kuqinisekiswe ukukhiqizwa kwekhwalithi ephezulu. Kusukela ekulungiseni izinto zokusetshenziswa kuya ekulawuleni okunembile kwemingcele yokuphonsa, lo mshini umelela isiqongo sokuqanjwa kabusha kwezobuchwepheshe emkhakheni wokusakazwa kwensimbi. Ikhono layo lokukhiqiza ukusakaza kwefomu elide okuqhubekayo ngokunemba okukhethekile kobukhulu kanye nezakhiwo ze-metallurgical kuyenza ibe ithuluzi elibalulekile ekukhiqizeni izinsimbi eziyigugu ezisezingeni eliphezulu nemikhiqizo ye-alloy. Njengoba ubuchwepheshe buqhubeka nokuthuthuka, ama-vacuum aqhubekayo aqhubekayo azodlala indima ebalulekile ekulolongeni ikusasa lezinsimbi eziyigugu kanye nokukhiqizwa kwe-alloy.
