Ukusakaza Ukukhubazeka Okujwayelekile

Ama-casting ayisithupha ajwayelekile amaphutha'izimbangela kanye nendlela yokuvimbela, hhayi ukuqoqakuzobaukulahlekelwa kwakho! ((Ingxenye 1)

Inqubo yokukhiqiza yokusakaza, izici ezinomthelela kanye nenkinga yokukhipha noma ukwehluleka akunakugwenywa, okuvame ukuletha ukulahlekelwa okukhulu ebhizinisini. Namuhla, ngizokwethula izinhlobo eziyisithupha zokukhubazeka okujwayelekile kanye nesixazululo, ngethemba ukuthi kuwusizo embonini ye-Foundry.

1I-Porosity (amabhamuza, imbobo yokuklinya, iphakethe)

1)Izici:I-Porosity ikhona ngaphakathi kwendawo yokuphonsa noma izimbobo, ziyindilinga, ziyi-oval noma ezimise ngendlela engavamile, ngezinye izikhathi izimbotshana eziningi zakha isisindo somoya ngaphansi kwesikhumba ngokuvamile esimise okwepheya. Khipha imbobo umumo ongajwayelekile kanye nendawo emangelengele. I-Pocket iyindawo eqondile endaweni ebushelelezi. I-pore ekhanyayo ibonakala ngokuhlola, i-pinhole ingatholakala ngemva kokucubungula ngomshini.
2)Izimbangela:
l Izinga lokushisa langaphambi kokushisa kwesikhunta liphansi kakhulu, insimbi ewuketshezi idlula ohlelweni lokuthela ipholisa ngokushesha kakhulu.
l Umklamo ongemuhle we-mold exhaust, amagesi awakwazi ukukhishwa ngaphandle kokuvinjwa.
l Upende awumuhle, ukhipha umoya omubi ngokwawo, okuhlanganisa nokushintshashintsha kwawo noma amagesi okubola.
l Izimbobo zomgodi wesikhunta kanye nemigodi, emva kokuba insimbi ewuketshezi ithelwa emigodini, ukunwetshwa okusheshayo kwegesi yomgodi ecindezelwe insimbi ewuketshezi ukwenza imbobo eklinyiwe.
l Umgodi wesikhunta uyagqwala futhi awukahlanzwa.
l Izinto ezisetshenziswayo (ama-cores) agcinwe ngendlela engafanele, ngaphandle kokushisisa ngaphambi kokusetshenziswa.
l I-ejenti yokwehlisa kabi, noma umthamo ongafanele noma ukusebenza ngendlela engafanele.
3) Indlela yokuvimbela:
l isikhunta ukuze sishise ngokugcwele, ukumboza (i-graphite) usayizi wezinhlayiyana akufanele kube kuhle kakhulu futhi kube nokuphefumula okungcono.
l Sebenzisa indlela yokulingisa etshekile.
l Izinto ezingavuthiwe kufanele zigcinwe endaweni eyomile nengenisa umoya, lapho zisetshenziselwa ukushisa kuqala.
l Khetha umphumela we-deoxidation omuhle wokunciphisa (i-magnesium).
l Izinga lokushisa lokuthela akufanele libe phezulu kakhulu.

2 Ukuncipha

1) Izici:I-shrinkage iyimbobo emangelengele engaphezulu ekhona ngaphezulu noma ngaphakathi kokubunjwa. Ukuncipha kancane kuwukuncipha okuncane okuhlakazekile kokusanhlamvu okumahhadla, okuvame ukwenzeka ekubunjweni eduze komgijimi, izimpande eziphakamayo, izingxenye eziwugqinsi, ukushuba kodonga kanye nendiza enkulu.

2) Izimbangela:
l Izinga lokushisa elisebenzayo lesikhunta alihlangabezananga nezidingo zokuqina kokuqondisa.
l Ukukhetha okungalungile kokugqoka, ukujiya kokugqoka akulawulwa ezingxenyeni ezahlukene.
l Isikhundla sokulingisa ekwakhiweni kwesikhunta asifanele.
l Umklamo wesikhuphukeli wehlulekile ukufeza indima ngokugcwele.
l Izinga lokushisa liphansi kakhulu noma liphezulu kakhulu.

3)Ungakuvimbela kanjani:
l Ukwandisa izinga lokushisa lesikhunta.
l Ukulungisa ukujiya kokunamathiswa okufuthwe ngendlela efanayo.Lapho upende uwa futhi udinga ukwakheka, akumele kwakheke ukunqwabelana kopende wendawo.
l Ukushisisa isikhunta sendawo noma ukufakwa kwasendaweni kusetshenziswa izinto zokufaka ezishisayo.
l Setha indawo eshisayo ibhulokhi yethusi bese upholisa indawo.
l Ukuklama irediyetha esikhunjeni, noma ngezinga lokupholisa elisheshayo ezindaweni zasendaweni ezifana namanzi, noma ukufafaza amanzi ngaphandle kwesikhunta.
l Ngocezu olubandayo olukhiphekayo, olubekwe ngokushintshana ngaphakathi kwembobo, ukuze kugwenywe lapho ukukhiqizwa okuqhubekayo, ukupholisa ngokwakho akwanele.
l Ukuklama idivayisi yokucindezela phezu kwesikhuphukeli sesikhunta.
l Ukuklama uhlelo lokungena ngokunembile, ukukhetha izinga lokushisa elifanele lokuthulula.

Izimbobo ezi-3 ze-slag (i-flux slag ne-metal oxide slag)

1) Izici:Imbobo ye-slag iyizimbobo ezikhanyayo noma ezimnyama ekubunjweni, konke noma ingxenye yomgodi yayigcwele i-slag. Ukwakheka okungajwayelekile, indawo encane ye-flux slag akulula ukuyithola, ngemva kokususwa kwe-slag, bese kukhombisa imbobo ebushelelezi. Okujwayelekile kusatshalaliswa engxenyeni engezansi yendawo yokuphonsa, eduze komgijimi noma ekhoneni lokuphonsa, i-oxide slag isakazwa kakhulu esangweni elinezikhala eduze kwendawo, kwesinye isikhathi ibe ngamaflakes noma ifu elingajwayelekile elinesemishi elishwabene noma leshidi, noma ama-flocculent castings, imvamisa iphuka isangweji nge-oxide. Ingenye yezimbangela eziyinhloko zokuklama imifantu.

2)Imbangela:Umgodi we-slag ubangelwa ikakhulukazi i-alloy smelting kanye nenqubo yokukhipha (kuhlanganise ne-gating system design engalungile), isikhunta ngokwaso asibangeli umgodi we-slag, futhi ukusebenzisa isikhunta sensimbi kungenye yezindlela eziphumelela kakhulu zokugwema i-slag.

3) Indlela yokuvimbela:
l Ukuklama isistimu yokugenca ngokunembile, noma sebenzisa isihlungi se-cast fiber.
l Ukusebenzisa indlela yokuthela ethambekele.
l Ukukhetha i-ejenti yokuhlanganisa futhi ulawule ikhwalithi ngokuqinile.

Amanye amaphutha okulingisa amathathu azoqhubeka ngesonto elizayo. Siyabonga.
