Isihloko: Ukuqonda ukusebenza kwe-i-vacuum caster evundlilengezinsimbi eziyigugu kanye nezinsimbi ezixubile

Ukusetshenziswa kobuchwepheshe obuthuthukisiwe kubalulekile lapho kukhiqizwa izinsimbi eziyigugu nama-alloy asezingeni eliphezulu. Umshini wokuphonsa oqhubekayo we-vacuum ovundlile uwubuchwepheshe obushintsha ngokuphelele inqubo yokukhiqiza. Lo mshini omusha udlala indima ebalulekile ekukhiqizweni kwezinsimbi eziyigugu nama-alloy ahlukahlukene, uletha ikhwalithi nokusebenza kahle okumangalisayo. Kule bhulogi, sizohlola ukusebenza okuyinkimbinkimbi kwe-caster evundlile evundlile evundlile, sihlole ukusebenza kwayo kanye nezinqubo ezibalulekile ezihilelekile ekukhiqizweni kwezinsimbi eziyigugu nama-alloy.

Ukusebenza kwe-horizontalumshini wokuphonsa oqhubekayo we-vacuumkuqala ngokulungiswa kwezinto zokusetshenziswa. Izinsimbi eziyigugu kanye nama-alloy akhethwa ngokucophelela futhi alungiselelwe inqubo yokubumba. Izinto zokusetshenziswa ziyancibilikiswa esithandweni sokushisa okuphezulu ukuze kufinyelelwe esimweni esifanele soketshezi lokubumba. Uma insimbi encibilikisiwe isifinyelele izinga lokushisa elifunekayo kanye nokuvumelana, ingadluliselwa ekamelweni lokubumba lomshini.

Uma insimbi encibilikisiwe ifakwa ekamelweni lokuphotha, indawo yokuphotha idlala indima ebalulekile ekuqinisekiseni ikhwalithi yenqubo yokuphotha. Ukungabikho komoya nokunye ukungcola ekamelweni lokuphotha kusiza ukuvimbela ukungcoliswa kwensimbi encibilikisiwe, okuholela emkhiqizweni wokugcina wekhwalithi ephezulu. Le ndawo yokuphotha ivumela nokulawulwa okungcono kwenqubo yokupholisa, okuvumela ukukhiqizwa kokuphotha okunembile nokulinganayo.

Ikamelo lokuthulula lomshini wokuphotha oqhubekayo we-vacuum ovundlile lifakwe uchungechunge lwezindlela zokupholisa ezinembile. Lezi zindlela zenzelwe ukupholisa insimbi encibilikisiwe ngokushesha njengoba idlula ekamelweni, ngaleyo ndlela kuthuthukiswe inqubo yokuqina. Ngokulawula izinga lokupholisa, umshini ungakhiqiza izinto eziphothayo ezinezakhiwo ezithile zensimbi, okuqinisekisa izici ezifiselekayo zomkhiqizo wokugcina.

Esinye sezici eziyinhloko zama-caster aqhubekayo e-vacuum avundlile yikhono lokukhiqiza ama-castings avundlile anobukhulu obude. Ngokungafani nezindlela zendabuko zokuphonsa lapho ubude bokuphonsa bungase bulinganiselwe, ama-caster e-vacuum avundlile angakhiqiza ubude obude bensimbi evundlile. Leli khono linenzuzo ikakhulukazi ekukhiqizweni kwezinsimbi eziyigugu nemikhiqizo ye-alloy, evame ukudinga ama-castings amade, afanayo ukuze kuqhutshekwe kucutshungulwe futhi kukhiqizwe.

Ukulawula isivinini sokukhipha izinto ngendlela eqondile kungenye isici esibalulekile sokusebenza komshini. Ngokulawula isivinini sensimbi encibilikisiwe egumbini lokukhipha izinto, abakhiqizi bangafinyelela usayizi kanye nezakhiwo zokuphonsa ezifiselekayo. Leli zinga lokulawula libalulekile ekukhiqizeni izinsimbi eziyigugu ezisezingeni eliphezulu kanye nemikhiqizo ye-alloy, lapho ukunemba kobukhulu kanye nokuvumelana kubalulekile.

Ngaphezu kwenqubo yokuphonsa ngokwayo, i-horizontal vacuum continuous caster isebenzisa nezinhlelo zokuqapha nokulawula ezithuthukisiwe. Lezi zinhlelo zivumela opharetha ukuthi baqaphe eduze amapharamitha ahlukahlukene enqubo yokuphonsa, okuhlanganisa izinga lokushisa, izinga lokupholisa kanye nesivinini sokuphonsa. Ngokuqapha nokulungisa njalo la mapharamitha, abakhiqizi bangaqinisekisa ikhwalithi yokuphonsa ehambisanayo ehlangabezana nezidingo eziqinile zezinsimbi eziyigugu kanye nokukhiqizwa kwe-alloy.

Umshini wokuphonsa oqhubekayo we-vacuum ovundlile uphinde ufakwe izindlela zokukhipha nokusika ezithuthukisiwe. Uma insimbi encibilikisiwe iqina ibe ukuphonsa okuqhubekayo, imishini ingasusa ngokunembile ukuphonsa ekamelweni bese iyisika ngobude obudingekayo. Le nqubo ezenzakalelayo iqinisekisa ukukhiqizwa okuphumelelayo kokuphonsa okufanayo, okuseqophelweni eliphezulu okulungele ukucutshungulwa nokukhiqizwa okuqhubekayo.

Ukuguquguquka kwama-vacuum casters avundlile kuwenza abe ngcono kakhulu ekukhiqizweni kwezinhlobo eziningi zezinsimbi eziyigugu kanye nama-alloy. Kungakhathaliseki ukuthi yigolide, isiliva, iplatinum noma ama-alloy akhethekile, umshini ungazivumelanisa nezinto ezahlukahlukene futhi ukhiqize ama-castings ngokunemba okukhulu kanye nokuvumelana. Lokhu kuguquguquka kubalulekile ekuhlangabezaneni nezidingo ezahlukahlukene zezimboni ezithembele ezinsimbini eziyigugu kanye nemikhiqizo ye-alloy esezingeni eliphezulu.

Ngamafuphi, ukusebenza kwe-vacuum continuous caster evundlile yezinsimbi eziyigugu nama-alloy kuhilela uchungechunge lwezinqubo eziyinkimbinkimbi ezihlelwe ngokucophelela ukuqinisekisa ukukhiqizwa kwezinsimbi eziyigugu nezihlanganisiwe. Kusukela ekulungisweni kwezinto zokusetshenziswa kuya ekulawulweni okunembile kwamapharamitha okuhlanganisa, lo mshini umelela isiqongo sobuchwepheshe emkhakheni wokuhlanganisa insimbi. Amandla awo okukhiqiza izinsimbi ezinde eziqhubekayo ezinokunemba okumangalisayo kanye nezakhiwo ze-metallurgical kwenza kube ithuluzi elibalulekile ekukhiqizeni izinsimbi eziyigugu nezihlanganisiwe ezisezingeni eliphezulu. Njengoba ubuchwepheshe buqhubeka nokuthuthuka, izinsimbi ezihlanganisiwe ezivundlile ngokungangabazeki zizodlala indima ebalulekile ekwakheni ikusasa lezinsimbi eziyigugu nokukhiqizwa kwe-alloy.
