China Zirconia Corundum Brick fekitari nevagadziri | Rongsheng

Tsanangudzo Pfupi:

Zirconia corundum brick rudzi rwemuviri wakachena wakasimba wakagadzirwa kubva kualuminium powder uye inenge 65% ZrO2 uye 34% SiO2 ine zircon jecha mukati, uye zirconia corundum firebrick inodururwa muforoma mushure mekunyungudutswa muchoto chemagetsi. zirconia corundum moto zvidhinha ndezveasidhi refractory zvinhu zvine hunhu hwakasiyana-siyana hwepamusoro mechanical simba, yakanaka yekupisa kuvhunduka kusagadzikana, yakakwirira refractoriness pasi pemutoro, kusimba kwekukukurwa kwevhu uye high density uye nezvimwe. zirconia corundum refractory zvidhinha zvinogona kushandiswa zvakanyanya muvira regirazi, Ladle, choto chakachena chesimbi, simbi isina-ferrous simbi inonyungudutsa choto uye zvichingodaro.

zircon corundum block inogadzirwa ine yakagadzikana zircon jecha uye pamusoro pe64% zircon zvemukati. zircon corundum fire block inodururwa mu mold mushure mekunyungudutswa muchoto chemagetsi. iyo lithofacies chimiro chine eutectoid uye girazi zvikamu zve corundum uye zirconium plagioclase. zircon corundum refractory block petrographic chimiro chakagadzirwa ne eutectoid uye girazi chikamu che corundum uye zirconium clinopyroxene. zircon corundum zvidhinha zvine zvimiro zvekusimba kwesimba remagetsi, yakanaka yekupisa kuvhundutsa kuramba, yakakwirira refractoriness pasi pemutoro, kusimba kwekukukurwa kwevhu uye kusimba kwepamusoro.

Zvivakwa zveZirconia Corundum Brick

  • High refractoriness pasi pemutoro,
  • Yakanakisa thermal shock resistance,
  • Good corrosion resistance,
  • High mechanical simba,
  • Great creep resistance,
  • High density.

Zirconia Corundum Brick Manufacturing Process

Zirconia corundum zvidhinha inofarira zviyero zve1: 1 zircon jecha uye indasitiri alumina poda uye wedzera mashoma vhoriyamu yeNaZO, B20 mumiriri wemusanganiswa mushure mekusanganiswa zvakakwana kuburikidza nekunyungudutswa uye kudururira muforoma pakupisa kwakanyanya kwe1900 ~ 2000 ℃ zvichikonzera kuti chidhinha chakakandwa chine 33. % ZrO2 zvemukati. Pahwaro, tora chikamu che desilicication zircon jecha seyakagadzirwa kugadzira chidhinha chakasanganiswa chine 36% ~ 41% ZrO2 zvemukati.

Kurongeka kweZirconia Corundum Brick

AZS-33
AZS33 zirconia corundum zvidhinha dense microstructure inoita kuti girazi rirambe riripo pakukukurwa kwegirazi kuita risiri nyore kugadzira matombo kana kumwe kukanganisa, uye mukana wekugadzira mabhuru madiki egasi wakadzikira.

AZS-36
Mukuwedzera kune imwechete eutectic seAZS-33 zirconia corundum firebrick, AZS-36 zirconia corundum zvidhinha nekuda kwekuwedzera kweketani-se-zirconia makristasi, uye zvinyorwa zvegirazi zvakaderera.

AZS-41
AZS-41 zirconia corundum moto zvidhinha ine mamwe yunifomu kugoverwa kwezirconia makristasi, mu zirconia corundum series, kurwisa kwayo kwekukukurwa ndiko kwakanyanya.

Kushandiswa kweZirconia Corundum Brick

Zircon corundum zvidhinha zvinonyanya kushandiswa muvira indasitiri choto, girazi remagetsi choto, siraidhi honi yesimbi nesimbi indasitiri, sodium metasilicate indasitiri yevira yekuramba kunyura kwemakemikari uye mechaniki pakupisa kwakanyanya.
