Silica refractory brick is acid refractory uye ine yakanaka acid slag erosion resistance. Slica zvidhinha refractoriness pasi pemutoro inosvika 1640 ~ 1690 ℃, inoratidzika yekutanga kupfava tembiricha ndeye 1620 ~ 1670 ℃ uye yechokwadi density i2.35g/cm3. Silicon moto zvidhinha inogona kushanda mukupisa kwakanyanya kwenguva yakareba uye kuchengetedza vhoriyamu kugadzikana pasina shanduko. Silicon rectory zvidhinha ine zvinopfuura 94% SiO2 zvemukati. Silicate zvidhinha ine yakakwirira tembiricha simba uye yakaderera thermal kuvhunduka kuramba. Silicate moto zvidhinha zvinogadzirwa neakasikwa silica ore seyakagadzirwa, yakawedzerwa yakakodzera mineralizer kusimudzira quartz mumuviri wakasvibira wakashandurwa kuita tridymite uye kupiswa zvishoma nezvishoma kuburikidza tembiricha ye1350 ~ 1430 ℃ mukuderedza mamiriro ekunze. Kana kupisa kusvika 1450 ℃, pane account 1.5 ~ 2.2% yehuwandu hwekuwedzera vhoriyamu. Iyi mushure-yekuwedzera ichaita kuti kubatana-kucheka kuvharwa uye kuve nechokwadi kuti chivakwa chinochengetedza mhepo yakanaka impermeability uye kusimba kwechimiro.

Zvivakwa zveSilica Fire Brick

Yakanaka asidi erosion kuramba,
High tembiricha simba,
High refractoriness: 1690 ~ 1710 ° C,
Yakakwirira RUL: inenge 1620-1670 ℃,
Volume kugadzikana pakupisa kwakanyanya,
Good thermal shock resistance.

Kuumbwa kweSilica Fire Brick

Silicon fire block idhinha refractory iyo silica content inopfuura 93%, 50% -80% ye tridymite, 10% -30% ye cristobalite, quartz uye girazi chikamu, nezve 5% -15%. Iyo mineralological kuumbwa kwesilicate zvidhinha inonyanya kuyera quartz uye quartz, pamwe nediki diki quartz uye vitreous. Scale quartz, quartzite quartz uye yakasara quartz inoshanduka zvakanyanya muhuwandu nekuda kwekushandurwa kwekristaro chimiro pakudzika kwakadzika, saka kugadzikana kwekupisa kwesilicate refractory zvidhinha hakuna kunaka pakudziya kwakaderera. Mukushandisa maitiro, pasi pe800 ℃ kunonoka kupisa uye kutonhora, kuitira kuti udzivise kutsemuka. Saka haifanirwe kunge iri pasi pe800 ℃ tembiricha inosvetuka muchoto.

Silica Fire Brick Manufacturing Process

Silicate zvidhinha zvemoto zvinogadzirwa kubva ku quartzite ine diki diki ye mineralizing agent. Kana yapiswa nekupisa kwakanyanya, silica refractory zvidhinha mineral composition inoumbwa nescale quartz, quartzite quartz, girazi uye mamwe akaomarara echikamu matissue akaumbwa pakupisa kwakanyanya, uye AiO2 yemukati inodarika 93%. Pakati pezvidhinha zviri nani zvakapiswa silica, zviri mukati mechiyero chequartz ndicho chepamusoro, chinoverengera 50% ~ 80%. cristobalit yaitevera, ichiverengera chete 10% kusvika 30%. Zviri mukati mequartz uye girazi chikamu chinoshanduka pakati pe5% ne15%

Kushandiswa kweSilica Fire Brick

Silica moto zvidhinha zvinonyanya kushandiswa sezvinhu zvinodzivirira zvekudzivirira madziro ekamuri yekubikira uye combustor muhovheni yecoke, kamuri inodzoreredza uye homwe ye slag muchoto chesimbi yakavhurika, kunyura mugomba uye girazi rinonyunguduka choto, uye imwe nzvimbo inotakura uremu uye kumusoro muceramic. honi yekupfurisa. Silicate zvidhinha zvakare inogona kushandiswa kune huremu nzvimbo mukupisa kwakanyanya uye pamusoro peasidhi yakavhurika yevira remoto.
