I-Ceramic Sand for Lost Foam Casting

Incazelo emfushane:

Isihlabathi se-Ceramic se-Foundry sisebenza kahle futhi: izidingo eziphansi zemishini yokwelapha isihlabathi, ukusetshenziswa kwamandla okuphansi kanye nezindleko eziphansi zokwelashwa kwesihlabathi. Izinga lokutholwa kwesihlabathi lifinyelele ku-98%, likhiqiza imfucuza encane. Ngenxa yokungabikho kwe-binder, isihlabathi sokugcwalisa igwebu elahlekile sinezinga eliphezulu lokubuyisela kanye nezindleko eziphansi, ezifinyelela ku-1.0-1.5kg/ton yokusetshenziswa kwesihlabathi sokubunjwa.

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Eminyakeni yamuva nje, amabhizinisi alahla amagwebu alahlekile athintwe izinto eziningi, okuholele emazingeni aphansi afanelekayo okuphonswa kwe-cast. Phakathi kwazo, izindleko eziphezulu zokukhiqiza zokulingisa, izinga eliphezulu lokukhubazeka kanye nekhwalithi ephansi kube yizinkinga ezintathu ezinkampanini ezilahlekile zokuphonsa igwebu eChina. Indlela yokuxazulula lezi zinkinga nokuthuthukisa ukusebenza kwezindleko zemikhiqizo yokusakazwa kusenesikhathi kube ngomunye wemisebenzi ephezulu yezinkampani ezisunguliwe. Njengoba sonke sazi, ukukhethwa kwesihlabathi enqubweni yokubunjwa kuyingxenye ebalulekile yenqubo yonke. Uma isihlabathi singakhethiwe kahle, sizothinta sonke isimo. Ngakho-ke, amabhizinisi alahlekile aphonsa amagwebu kufanele enze imizamo eyengeziwe ekukhetheni isihlabathi.

Ngokusho kwedatha efanelekile, izinkampani eziningi ze-Foundry ziye zathuthukisa ukukhetha kwazo kwesihlabathi, zenqaba isihlabathi se-quartz esinentengo ephansi noma isihlabathi se-forsterite, futhi zisebenzisa uhlobo olusha lwesihlabathi se-ceramic ye-foundry ukuthuthukisa inkinga yokuphonsa. Lolu hlobo olusha lwesihlabathi lunezinzuzo zokungaguquguquki okuphezulu, uketshezi oluhle, ukufinyeleleka kwegesi ephezulu kanye nokuminyana kwenqwaba okufanayo ngesihlabathi se-quartz. Ixazulula izingqinamba ekukhiqizeni ukusakaza ngezinga elithile, futhi ikhathazeke kakhulu yimboni yamazwe ngamazwe yokusungula. Izinkinga ezintathu ezinkulu zezindleko zokuphonsa, izinga elingasebenzi kahle kanye nekhwalithi yezinkampani ezilahla igwebu ezilahlekile ziye zadanjiswa ngempumelelo, futhi isihlabathi se-ceramic se-foundry sithandwa amabhizinisi amaningi.

Inzuzo

● High refractoriness (＞1800°C)，can be used for casting various materials. There is also no need to use different sand type according to material.

● Izinga lokufuna kabusha eliphezulu. Izinga lokutholwa kwesihlabathi lifinyelele ku-98%, likhiqiza imfucuza encane.

● I-fluidity enhle kakhulu nokusebenza kahle kokugcwalisa ngenxa yokuba yindilinga.

● Ukunwetshwa kwe-Thermal okuphansi kanye nokuqhutshwa kwe-Thermal. Ubukhulu bokusakaza bunembe kakhulu futhi ukuhanjiswa okuphansi kunikeza ukusebenza okungcono kwesikhunta.

● Ukuminyana kwenqwaba ephansi. Njengoba isihlabathi sokwenziwa se-ceramic sicishe sibe uhhafu wokukhanya njengesihlabathi se-ceramic esihlanganisiwe (isihlabathi sebhola elimnyama), i-zircon ne-chromite, singaphenduka cishe kabili inani lezibunjwa ngeyunithi ngayinye yesisindo. Ingase futhi isingathwe kalula kakhulu, ukonga abasebenzi kanye nezindleko zamandla okudlulisa.

● Ukunikezwa okuzinzile. Amandla onyaka angu-200,000 MT ukugcina ukunikezwa okusheshayo nokuzinzile.
