Pane musiyano mukuru pakati pezvidhinha zvevhu uye yakakwirira alumina zvidhinha, asi musiyano uri papi?

Zvidhinha zvevhu zvine aluminium inokwana 35% -45%. Yakagadzirwa nevhu rakaoma clinker, yakasanganiswa nechidimbu chekukura zvinodiwa, inoumbwa uye yakaomeswa, uye inopiswa patembiricha ye1300-1400 ° C. Kupfurwa kwezvidhinha zvevhu ndiko kunonyanya kuita kuenderera mberi kupera mvura uye kuora kwekaolin kuumba mullite crystals. Zvidhinha zvevhu hazvina kusimba acidic refractory zvigadzirwa, izvo zvinogona kuramba kukukurwa kweasidhi slag uye acid gasi. Zvidhinha zvevhu zvine zvinhu zvakanaka zvekupisa uye zvinodzivirira kutonhora nekukurumidza uye nekukurumidza kupisa.

Zvidhina zvevhu

Mune tembiricha ye0-1000 ℃, huwandu hwezvidhinha hwevhu huchawedzera zvakaenzana nekuwedzera kwekushisa. Iyo mutsara yekuwedzera curve inosvika kumutsara wakatwasuka, uye mutsara wekuwedzera mwero ndeye 0.6% -0.7%. Kana tembiricha yasvika 1200 ℃, Kana tembiricha ikaramba ichikwira, huwandu hwayo hunotanga kudzikira kubva pakuwedzera kwepamusoro. Mushure mekunge tembiricha yechidhinha chevhu ichipfuura 1200 ℃, iyo yakaderera kunyungudika muzvidhinha zvishoma nezvishoma inonyunguduka, uye zvimedu zvakatsikirirwa kune mumwe nemumwe nekuda kwekunetsana kwepamusoro, zvichikonzera vhoriyamu shrinkage.

High-alumina refractory zvidhinha zvigadzirwa zvinoramba zvine aluminium zvinyorwa zvinopfuura 48%. Iko refractoriness uye mutoro unonyorovesa tembiricha ye-high-alumina zvidhinha zvakakwirira kudarika zvidhinha zvevhu, uye kupikisa kwavo kwe-slag corrosion zviri nani, asi kugadzikana kwavo kwekupisa hakuna kunaka sezvidhinha zvevhu. High alumina zvidhinha zvine high density, yakaderera porosity uye kupfeka kuramba. Kune mamwe misoro yechoto uye zvidzitiro zvechoto, zviri nani kushandisa yakakwirira-aluminium zvidhinha zvekugadzira masonry; zvisinei, kana chiri chidhinha chevhu chakananga che carbon furnaces, hazvina kukodzera kushandisa zvidhinha zvepamusoro-aluminium, nokuti zvidhinha zvepamusoro-aluminium zvinowanzoita kupeta pakupisa kwakanyanya. Cocked angle.

Yakakwirira alumina zvidhinha

Zvidhinha zvakakwirira zvealumina zvinonyanya kushandiswa kugadzira mbariro dzemavira anoputika, zvitofu zvinopisa, matenga echoto chemagetsi, mavira anoputika, mavira anodzoreredza, uye mavhiri anotenderera. Pamusoro pe, yakakwirira alumina zvidhinha anoshandiswa zvakanyanya seyakavhurika yemoto regenerative cheki zvidhinha, mapulagi ekudira masisitimu, zvidhinha zvemhino, nezvimwe zvakadaro, mutengo wezvidhinha zvakakwirira zvealuminium wakakwira kupfuura zvidhinha zvevhu, saka zvidhinha zvevhu zvinofanirwa kushandiswa uko ivhu refractory zvidhinha zvinogona kuzadzisa zvinodiwa. .
