Nhau - High Alumina Bricks For Blast Furnace

High-alumina zvidhinha zvekuputira furnaces yakagadzirwa nepamusoro-giredhi bauxite seyakanyanya mbishi zvinhu, izvo zvakasungwa, zvakatsikirirwa, zvakaomeswa uye zvinopiswa pakupisa kwakanyanya.Izvo zvigadzirwa zvinoramba zvichishandiswa kugadzira kuputika kwemoto.

1. Zviratidzo zvemuviri uye zvemakemikari zvepamusoro alumina zvidhinha

2. Ndekupi zvidhinha zvakakwirira zvealuminium zvinoshandiswa mumoto unoputika?

High-aluminium zvidhinha zvakavakwa pachoto chevira chemoto unoputika.Iyo shaft yechoto inowanikwa muchikamu chepamusoro che blast furnace.Iyo dhayamita yaro zvishoma nezvishoma inowedzera kubva kumusoro kusvika pasi kuti ienderane nekuwedzera kwekupisa kwechaji uye kuderedza kukweshera kwemadziro echoto pakuchaja.Muviri wevira unogara muchoto chinoputika.50% -60% yehurefu hunobudirira.Munharaunda ino, jira rechoto rinoda kusangana nezvinodiwa zvakadaro, uye hunhu hwealumina akakwira zvidhinha zvakakwirira, kupfava kwakanyanya pasi pemutoro, acid resistance, alkali resistance, kuramba kwakasimba kukukurwa kweslag, uye kupfeka kwakanaka kuramba.Inogona kugutsikana, saka yakanyatsokodzera kuti blast furnace body igadzirwe nepamusoro alumina zvidhinha.

Izvo zviri pamusoro apa nhanganyaya kune yakakwira alumina zvidhinha zve blast furnaces.Mamiriro ekunze eiyo blast furnace yakaoma uye kune akawanda marudzi ezve refractory zvinhu zvinoshandiswa.High alumina zvidhinha ndeimwe yacho.Iko kune 3-5 tsanangudzo dzepamusoro alumina zvidhinha zvinoshandiswa.Robert's high alumina zvidhinha zvinogona kushandiswa mumhando dzakasiyana-siyana.Kana zvichidikanwa, tapota taura nesu.
