Ukusebenza kanye nezici zezitini ezikhanyisayo ze-zirconium corundum

I-Zirconium corundum izitini ezikhanyisayo zenziwe nge-alumina yezimboni nesihlabathi se-zircon. Ngokwenqubo yokukhiqiza, izitini ezi-reflexory ze-zirconium corundum zingahlukaniswa zibe izitini ezihlanganisiwe zirconium corundum kanye nezitini zintathu zirconium corundum.

Umakhi wezitini owakhayo waseHenan, owakhiqiza ibhola owakhayo, isitini esincane sokufakwa, iZhengzhou Huaxin High Temperature Material Co., Ltd.

Izitini ezihlanganisiwe zirconium corundum zivame ukubizwa ngokuthi isitini esimhlophe sensimbi, esaziwa nangokuthi isitini se-corundum clinoptilolite. Ukwakheka kwamakhemikhali okuyinhloko kungu-350% ～ 70% Al2O, 220% ～ 40% ZrO, kanti okunye yi-SiO2. Izinto eziyinhloko zamaminerali yi-zircon (ZrO2), i-corundum (α-Al2O3) nesigaba sengilazi. Amakristalu e-Zircon akha amathambo esitini. I-Zirconia inephuzu lokuncibilika eliphakeme (2715 ° C) nokuzinza okuhle kwamakhemikhali. I-Zircon ibola kakhulu kwimidiya ene-asidi ne-alkaline, ikakhulukazi engilazini encibilikisiwe.

Izitini ezihlanganisiwe ze-zirconium corundum zisetshenziswa ezithandweni zengilazi nakwezinye izithandani zezimboni. Izingxenye zesithando somlilo sengilazi ezisetshenziswe esithandweni sokuncibilikisa ingilazi zifaka udonga lwaphezulu oluphezulu, isithando somlilo esincane, isithando esincane somlilo, uthango lolimi nodonga lwebele. Izinkinga ezilandelayo kufanele zinakwe ekusetshenzisweni kwezitini ezihlanganisiwe zirconia corundum.

Izinguquko ezingajwayelekile ekukhulisweni okushisayo. Ijika lokunwetshwa kwezitini ezihlanganisiwe ze-zirconia corundum likhombisa isigaba esingajwayelekile eduze ne-1000 ℃. Izinguquko eziguqukayo zenzeka ngaphakathi kukristalu we-Zr02, futhi ivolumu lishintsha kakhulu. Ngakho-ke, izitini eziqukethe i-ZrO2 akufanele zisetshenziswe ezindaweni lapho izinga lokushisa linyuka kakhulu cishe ngo-1000 ° C. Kuhhavini, ushintsho lokushisa phakathi kuka-900 ～ 1150 ℃ akufanele lube lukhulu kakhulu, ngokuvamile akufanele lweqe u-15 ℃ / h, futhi izinga lokushisa kufanele likhuphuke ngokuqinile. Ezinye izindawo kufanele zivikelwe emakhazeni, futhi ezinye izitini kufanele zisetshenziselwe ukuzivikela ekuqhekekeni.

RinUkunciphisa. Ngenqubo yokuthela, kuvame ukuvela izimbobo zokuncipha, umzimba wezitini unezimbotshana eziningi, futhi ukubumbana kubi. Ngakho-ke, lapho kwakhiwa udonga lwengilazi yokuncibilikisa ingilazi, umgodi wokuncipha uzokhula uye ngasesikhaleni. Uma isango libheke ngaphandle, lapho umzimba wezitini ukhukhuleka ube ungqimba omncane kakhulu, kuzodala izingozi zokuvuza kwengilazi. Isetshenziswa esikhaleni esingenhla selangabi somlilo, esinempilo ende, futhi ayikho inkinga yokuphunyuka kuketshezi lwengilazi. Ngakho-ke, itheku lokusakaza lisetshenziswa ngaphandle ukunweba impilo yesevisi.

③ Eutectic. Lapho isitini esihlanganisiwe se-zirconia corundum sixhumana nesitini sobumba, i-eutectic izovela ngo-1300 ℃. Ngakho-ke, lapho kukhethwa izinto zokuphikisa, kufanele kugwenywe izinto ezibucayi ze-eutectic zalezi zinto ezimbili.

Isitini se-sintered zirconium corundum sibizwa nangokuthi i-ceramic bonded aluminium silicon zirconium brick. Uma kuqhathaniswa nezitini ezihlanganisiwe ze-zirconium corundum, izitini zintambo zirconium corundum zinamakhemikhali afanayo, kepha zinenzuzo yokungabi nekhabhoni, okuqukethwe kwesigaba sengilazi ephansi, ukwakheka okufanayo, akukho ukuncipha, ukuzinza kokushaqeka okuhle kokushisa, ukumelana nokugqwala, njll.
