Iibhloko ezinkulu zokuphosa ze-sillimanite kunye neebhloko eziphikisayo eziyalelwe ngabathengi baseYurophu kwiziko leglasi zipakishwe kwaye zilindele ukuthunyelwa.-ikopi

Inkqubo yokuveliswa kwezi bhloko ibandakanya ukudibanisa kweendlela zendabuko kunye nezanamhlanje. Eyaziwayo ngokuhlala kunye nokuchasana nokushisa okuphezulu, iibhloko ze-Fireclay eziphonsiweyo zibunjwe ngononophelo kwaye zifakwe kwii-kilns ukufezekisa amandla afunekayo kunye nokuxinana. Ukuchithwa kweebhloko ze-sillimanite, ngakolunye uhlangothi, kubandakanya ukusetyenziswa kobuchwephesha obuphezulu bokudala izitena ezixineneyo, eziphakamileyo ezilungele ukusetyenziswa kwiziko leglasi.

Emva kokuba iibhloko zenziwe, zingena kwinkqubo yokulawula umgangatho ongqongqo ukuqinisekisa ukuba ziyahlangabezana nemigangatho engqongqo efunekayo kwizicelo zemizi-mveliso. Oku kubandakanya amandla oxinzelelo, ukuhanjiswa kwe-thermal kunye novavanyo lokumelana neekhemikhali. Izitena kuphela eziphumelele ezi mvavanyo zikhethiweyo ukupakishwa kunye nokuthunyelwa.

Inkqubo yokupakisha ibalulekile ekuqinisekiseni ukuba izitena zifika kwindawo eziya kuyo zinjalo. Ibhloko nganye ipakishwe ngononophelo kwaye ipakishwe kwiikhreyithi ukunqanda ukophuka ngexesha lokuhanjiswa. Ukupakishwa kweebhloko ze-cast sillimanite kufuna ingqalelo ekhethekileyo njengoko ubungakanani babo obukhulu kunye nobunzima bufuna ukhathalelo olongezelelweyo ukuqinisekisa ukuthutha okukhuselekileyo.

Nje ukuba iibhloko zipakishwe, zilungele ukuthunyelwa kwiindawo eziya kuzo eYurophu. Ulungiselelo lokuthumela ngaphandle izixa ezikhulu kangaka zezitena zifuna ukucwangciswa ngononophelo kunye nolungelelwaniso ukuze kuqinisekiswe ukuhanjiswa kwangethuba. Ezi zitena zilayishwa kwiikhonteyina zize zithuthelwe kumazibuko, apho ziye zilayishwe kwiinqanawa zemithwalo eziya phesheya kolwandle.

Ukuthunyelwa kumazwe angaphandle kwezi zitena zikumgangatho ophezulu ezityekisayo eYurophu bubungqina bobuchule kunye nobuchule bokwenza izitena. Abathengi baseYurophu bayaqaphela umgangatho ophezulu wezi zitena kunye nokubaluleka kwazo ekugcineni ukusebenza kakuhle kunye nokuthembeka kweziko zabo zeglasi. Imfuno yezi zitena ibonisa imfuno ekhulayo yezixhobo eziqhubela phambili zokuchasa kwizicelo zemizi-mveliso kwilizwekazi liphela.

Njengoko imarike yezitena ezichasene nehlabathi iqhubeka nokukhula, abavelisi bayaqhubeka nokuvelisa izinto ezintsha ukuhlangabezana neemfuno eziguqukayo zabathengi. Ukudibanisa iindlela zemveli ezifana nezitena zodongwe kunye neendlela zanamhlanje ezifana nezitena ze-sillimanite zivumela abavelisi ukuba bavelise uluhlu olubanzi lweemveliso ezikumgangatho ophezulu ukuhlangabezana neemfuno zamashishini ahlukeneyo.

Isishwankathelo, ukupakishwa kunye nokuthunyelwa kweebhloko ezinkulu ze-sillimanite kunye ne-refractory dongwe kubathengi baseYurophu kubonisa impumelelo ebalulekileyo kwishishini lokwenziwa kwezitena. Ukuthunyelwa kumazwe angaphandle kwezi zitena zodidi oluphezulu zombane kugxininisa ukuzibophelela kweshishini ekuhlangabezaneni nemfuno ekhulayo yemathiriyeli ephucukileyo kwizicelo zemizi-mveliso. Njengoko iimarike zehlabathi ziqhubeka nokuvela, abavelisi baya kuqhubeka bedlala indima ebalulekileyo ekuboneleleni ngezisombululo ezintsha zokuhlangabezana neemfuno zabathengi.
