I-Alumina Refractory Raw Materials Technology Exchange ka-2017 yaphetha ngempumelelo, yabelana ngobuhlakani bemboni kanye nokuqanjwa okusha kwezobuchwepheshe.

Ngomhla zingama-21 kuMbasa, 2017, "i-Alumina Refractory Raw Materials Technology Exchange Conference" ebilindelwe ngabomvu yabanjelwa eShandong. Ingqungquthela ihlelwe ngokuhlanganyela yi-Shandong Zhongnai High Temperature Materials Co., Ltd. (ngemuva kwalokhu ebizwa ngokuthi "Shandong Zhongnai") kanye ne-Shandong Hengjia High Purity Refractory Raw Materials Co., Ltd. (ngemuva kwalokhu ebizwa ngokuthi "i-Hengjia High Purity"). Izinkampani ezaziwayo ezingaphezu kuka-60 kanye nezicukuthwane ezingaphezu kuka-120 ezivela ezweni lonke zahlangana ndawonye. I-China Refractory Industry Association kanye nenkundla yezindaba i-China Refractory Window Network ibambe iqhaza ekubikeni kuwo wonke umcimbi futhi yanikeza ukusekelwa okuqinile ekubanjweni ngempumelelo kwalo mcimbi.

Umcimbi wokuvula le ngqungquthela ubusingathwe nguMnu. Chen Zhiqiang, owayengunjiniyela omkhulu weLuoyang Refractory Research Institute kanye nowayengumphathi-jikelele we-Elkem Asia Pacific. UMnu. Liu Wei, uMongameli we-China Refractory Industry Association kanye noSihlalo we-Shandong Refractory Group Co., Ltd., kanye noMnu. Sun Jian, uNobhala Wekomidi Leqembu laseLinchi Town, E-Zouping County, Idolobha lase-Binzhou, eSifundazweni SaseShandong, bethula izinkulumo ngokulandelana, bezwakalisa ukuhalalisela kwabo ngokubamba ngempumelelo le ngqungquthela nokwamukela kwabo okufudumele izihambeli.

Enkulumweni yakhe yokuvula, uMnu. Liu Wei waveza ukuthi imboni yeSifundazwe SaseShandong ephikisayo ibilokhu ihlinzeka ngamandla aqhubekayo okuthuthukisa imboni ngokuqongelela kwayo okujulile kwezobuchwepheshe kanye nomoya wokusungula. Kodwa-ke, eminyakeni yamuva nje, ngenxa yokuqhubeka kokwehla kwesidingo sezinto eziphikisayo, okuhambisana nomthelela wezingcindezi eziningi ezifana nezinqubomgomo zoxhaso lwezimali kanye nokuvikelwa kwemvelo, imboni ibhekene nezinselele ezingakaze zibonwe ngaphambili. Ikakhulukazi, inqubomgomo yokuncishiswa kwamandla okukhiqiza ngendlela eyinqaba eyethulwa yiDolobha laseZibo yehlise umthamo wokuqala wokukhiqiza wamathani ayizigidi ezi-3.3 kuya kumathani ayizigidi eziyi-1.5, okwaletha izinselele ezinkulu ekuthuthukisweni okusimeme kwamabhizinisi.

Bebhekene nesimo semakethe esiyinkimbinkimbi, u-Shandong Zhongnai kanye no-Hengjia Gaochun baye baqhubeka bekhulisa utshalomali lwabo ocwaningweni nokuthuthukiswa kwezobuchwepheshe futhi bathuthukisa ngempumelelo uchungechunge lwezinto ezingavuthiwe ezintsha, njenge-alumina micropowder kanye nemikhiqizo yochungechunge lwe-corundum emise okwepuleti. Ngokusebenza kwabo okuhle kakhulu kanye nekhwalithi ezinzile, ziye zasetshenziswa kabanzi futhi zaqashelwa kakhulu izinkampani eziphikisayo ekhaya nakwamanye amazwe. Lokhu akulethanga nje kuphela isithunzi esihle semakethe enkampanini, kodwa futhi kwaba negalelo elihle ekuthuthukiseni izinga eliphelele lemboni ephikisayo.

Lo mhlangano wokushintshisana ngezobuchwepheshe uhlanganise ndawonye ochwepheshe bezobuchwepheshe bokuphikisa abaphezulu abavela ekhaya naphesheya ukuze babelane ngemiphumela eminingi yocwaningo lwesayensi olusezingeni eliphezulu kanye nemininingwane yezimboni. Ekuqaleni komhlangano, uMphathi-Jikelele u-Shao Changbo wethule umbiko wokuvula ngendikimba ethi "Ingxoxo ngokusetshenziswa kwe-corundum emise okwepuleti kanye ne-α-Al2O3 ezintweni eziphikisayo". Wenza ukuhlaziywa okujulile kwezici zokusebenza, inqubo yokukhiqiza kanye nezindawo zokusetshenziswa kwe-alumina micropowder kanye nemikhiqizo yochungechunge lwe-plate-shaped corundum, futhi wachaza indima ebalulekile yale mikhiqizo ezintweni eziphikisayo kanye nezindlela zabo zokuthuthukiswa zesikhathi esizayo.

Embikweni olandelayo, uSolwazi Ye Guotian ovela eSikoleni Sesayensi Yezinto Zokusebenza kanye Nobunjiniyela eNyuvesi yaseZhengzhou unikeze umbiko othi "Ithonya Le-Micropowder Morphology on the Fluidity of Pumped Castables in Pipelines", uhlongoze umthelela obalulekile we-micropowder morphology ku-fluidity of castables, futhi wanikeza isiqondiso sobuchwepheshe esiqondiswe kochwepheshe bemboni. UDkt. Xu Guotao, uchwepheshe oyinhloko wezinto eziphikisayo e-Wuhan Iron and Steel Research Institute, uhlaziye izinselele zobuchwepheshe nezisombululo zezinto ezingavuthiwe ze-alumina ohlelweni lwensimbi lwezinto eziphikisayo ngokombono wokusetshenziswa kwemboni yensimbi, futhi wanikeza isipiliyoni esiwusizo somkhakha.

UMnu. Gu Ligang, owayenguMqondisi we-R&D we-Vesuvius Asia Pacific, wethula imiphumela yokuhlolwa kwezinsimbi ezingenasimende ze-silica-alumina, wabonisa ukusetshenziswa kwe-binder entsha ethi "Si Ao" ezintweni eziphikisayo, futhi wafakazela ukusebenza kwayo okuhle kakhulu ngedatha namashadi. USolwazi Wang Zhoufu wase-Wuhan University of Science and Technology wabelane ngombiko othi "Hydration Behavior and Regulation of Hydrable Alumina", echaza kabanzi ngokusetshenziswa kwe-alumina ekwazi ukumelana ne-hydratable ezintweni eziphikisayo ze-amorphous kanye nomthelela wokuziphatha kwayo kwe-hydration ezintweni ezibonakalayo.

Ekupheleni kwalo mhlangano wokushintshisana ngezobuchwepheshe, uMnu. Jiang Hong ulethe umbiko othi "Ingxoxo Ngokusetshenziswa Kwezinga Eliphezulu Le-Refractory Aggregates and Powders in Iron Trench Materials" ezivakashini, eqhubeka nokudingida isimo samanje namathemba okusetshenziswa kwama-refractory aggregates kanye nezimpushana ezintweni zensimbi, futhi egcizelela izinzuzo ezibalulekile zokumelana nokushaqeka kwe-tabular corundum.

Phakathi nomhlangano, izihambeli ziphinde zavakashela i-Shandong Zhongnai kanye ne-Hengjia High Purity Company, futhi zazuza ukuqonda okujulile ngezimpumelelo ezivelele zenkampani ocwaningweni nasekuthuthukisweni nasekukhiqizeni izinto eziphikisayo. Ukuze kuqinisekiswe ukuzinza kwekhwalithi yomkhiqizo, u-Shandong Zhongnai kanye no-Hengjia Gaochun batshale imali engaphezu kwezigidi ezingu-8 zamayuan ukuze basungule isikhungo sokucwaninga nokuthuthukiswa kwe-alumina-based refractory, esihlome ngemishini yokuhlola ethuthukisiwe njengama-microscopes ama-electron, imitshina yesigaba se-XRD, kanye nemishini yokuhlola ukumelana nokushaqeka okuzenzakalelayo okuzenzakalelayo. Lolu chungechunge lokutshalwa kwezimali kwe-R&D luhlinzeka ngosekelo oluqinile lwezobuchwepheshe lokuqinisekisa ikhwalithi yomkhiqizo futhi lwenza inkampani inikeze amakhasimende ngezinsizakalo zokuhlola impahla eluhlaza ezinembe kakhudlwana nangokwesayensi.

Lo mhlangano wokushintshana ngobuchwepheshe awuzange nje unikeze inkundla yokuxhumana okujulile kwabahlanganyeli, kodwa futhi ubonise ubuchwepheshe obuvelele kanye nempumelelo emisha ye-Shandong Zhongnai kanye ne-Hengjia High Purity emkhakheni wezinto zokusetshenziswa kwe-alumina refractory. Ngale ngqungquthela, ochwepheshe bezimboni baxoxisane nezindlela zokuthuthuka nezindlela ezintsha zobuchwepheshe zezinto eziphikisayo, zinikeza isiqondiso esibalulekile kanye nogqozi lwentuthuko yesikhathi esizayo yemboni.

Abahlanganyeli ngokuvamile bazwakalise ukuthi le ngqungquthela bekungekona nje ukwabelana ngobuchwepheshe, kodwa futhi iqoqo lobuhlakani bemboni. Babheke ngabomvu izingqungquthela ezifanayo esikhathini esizayo ezizoletha imibono emisha kanye nempumelelo embonini. U-Shandong Zhongnai no-Hengjia Gaochun bathembele emoyeni wabo "wobungcweti, ukugxilisa ingqondo nokugxila", ukugxila kukhwalithi yomkhiqizo kanye nocwaningo nokuthuthukiswa kwezobuchwepheshe, futhi ngokuqhubekayo bakhuthaze ukuthuthukiswa kwezinto ezingavuthiwe ezisekelwe ku-alumina-based refractory. Ngokuzayo, ngokuqinisekile bazoba sesikhundleni esibaluleke kakhulu ezimakethe zasekhaya nezangaphandle futhi bafake isandla ngamandla ekususeni imboni yempahla eqinile yezwe lami.
