Kwishishini lokuvelisa, ukusetyenziswa kweizixhobo ezikumgangatho ophezulukwaye izixhobo zibalulekile ekuveliseni iimveliso ezikumgangatho ophezulu. Enye into enjalo edlala indima ebalulekileyo kwinkqubo yokuphosa intsimbi yiityhubhu yokungunda yobhedu. Ezi zityhubhu zisetyenziselwa ukuphosa ngokuqhubekayo kwentsimbi ukuqinisekisa ukuhamba kakuhle kunye nokuhamba kakuhle kwesinyithi esityhidiweyo. I-China ngomnye wabavelisi abahamba phambili betyhubhu zokubumba ubhedu, kunye neemveliso zabo, ezifana neTP2 ityhubhu yokubumba ubhedu, zifunwa kakhulu ngenxa yomgangatho wazo kunye nokuqina kwazo.

Iityhubhu yobhedu yecrystallizer, eyaziwa ngokuba ityhubhu yobhedu yokubumba, iyinxalenye ebalulekileyo kwinkqubo yokuphosa eqhubekayo. Umsebenzi wayo ophambili kukuququzelela ukuqiniswa kwentsimbi etyhidiweyo ukwenza i-slab eqinile. Umbhobho unika indawo egudileyo ukuze insimbi iqine, iqinisekisa umgangatho kunye nokunyaniseka kwemveliso yokugqibela. I-China inodumo olomeleleyo lokuvelisa iityhubhu zobhedu ezikhazimlayo ezikumgangatho ophezulu ezihlangabezana neemfuno ezingqongqo kushishino lokuvelisa.

Enye yeenzuzo eziphambili zokusebenzisa iityhubhu zaseTshayina zobhedu kunye neekristali kukuqhuba kwazo okuphezulu kwe-thermal. I-Copper yi-conductor egqwesileyo yokushisa, evumela ukuhanjiswa kobushushu ngokufanelekileyo ngexesha lenkqubo yokuphosa. Oku kunceda ekulawuleni ukuqina kwentsimbi kunye nokuqinisekisa ukupholisa okufanayo, okuyimfuneko ekuveliseni iimveliso zetsimbi eziphezulu. I-TP2 ye-copper mold tube, ngokukodwa, iyaziwa ngokuba yi-thermal conductivity egqwesileyo, iyenza ibe yinto ekhethwayo kubenzi bentsimbi.

Enye into ebalulekileyo ekuvelisweni kweetyhubhu zokubumba ubhedu kunye neekristali kukumelana kwazo nokunxiba kunye nokubola. Ezi zixhobo zibonakaliswe kumaqondo okushisa aphezulu kunye neemeko ezinzima ngexesha lenkqubo yokuphosa insimbi, kwaye kufuneka zixhathise iindawo ezinjalo ukuze zigcine ukusebenza kwazo. Iityhubhu zokubumba zobhedu zaseTshayina kunye neekristali zakhiwe ukuze zihlale, kunye nokumelana kwazo okuphezulu nokunxiba, ukukhukuliseka kunye nokubola. Ubomi obude buqinisekisa iindleko ezincinci kunye nokugcinwa kweendleko, okwenza kube yisisombululo esinendleko kubenzi bentsimbi.

Ukongeza ekomeleleni kwazo kunye ne-thermal conductivity, iityhubhu zaseTshayina zobhedu kunye neekristali ziyaziwa ngobungakanani bazo obuchanekileyo kunye nokuphela komphezulu ogudileyo. Ezi mpawu ziyimfuneko ekuqinisekiseni ukuphosa okuchanekileyo kunye nokuhambelana kwentsimbi, eyona nto ibalulekileyo ekuveliseni iimveliso eziphezulu. Nokuba yityhubhu yokungunda yobhedu ye-TP2 okanye naluphi na olunye uhlobo, abavelisi baseTshayina bazibophelele ekuhambiseni iimveliso ezihlangabezana neemfuno ezingqongqo kushishino lwemveliso.

Ukuqukumbela, iityhubhu zokubumba ubhedu lwaseTshayina kunye neekristali zidlala indima ebalulekileyo kwinkqubo yokwenziwa kwentsimbi. I-conductivity ephezulu ye-thermal, ukuchasana nokunxiba kunye nokugqwala, kunye nemilinganiselo echanekileyo ibenza babe zizinto eziyimfuneko ekuveliseni iimveliso zetsimbi ezikumgangatho ophezulu. Nokuba yityhubhu yokungunda yobhedu ye-TP2 okanye ityhubhu yekristali yobhedu, abavelisi baseTshayina bazuze udumo ngokuvelisa iimveliso ezikumgangatho ophezulu ezihlangabezana neemfuno ezingqongqo kushishino lwemveliso. Njengoko imfuno yensimbi ephezulu iqhubeka nokunyuka, indima ye-tubes mold mold yase-China kunye ne-crystallizers kwishishini lokuvelisa iya kuba yinto ebaluleke kakhulu.
