Refractory bhora (kupisa kuchengetedza bhora)

1. Yakakwira alumina bhora ine hunhu hweakasimba oxidation kuramba uye slag kuramba. Iyo ceramic Refractory bhora inogona kutsiviwa uye kucheneswa, uye inogona kushandiswazve.

2. Main magadzirirwo ebara refractory: Φ40mm Φ50mm Φ60mm Φ70mm

3. Zvishandiso zvezvinhu zvinogadziriswa zvebhora zvakakamurwa kuita: yakakwira-aluminium, corundum, uye zirconium corundum.

4. Kune akawanda marudzi eanofungidzira mabhora, ayo anogona kushandiswa mune yakakwira uye yakadzika tembiricha yekushandura mafesi, vanochinja zvinhu, hydrogenation vashanduri, matangi ekuparadza, uye mabhora anokanganisa uye yekushisa michina yekushandura ayo anotsiviwa neanopisa mafesi mafesi mune yesimbi nesimbi indasitiri. .

5. Kuchengetedza kwekupisa porcelain mabhora anokanganisa ane zvakanakira simba rakakwirira uye kupfeka kuramba; hombe yekupisa kudziya uye kupisa kugona, kupisa kwakanyanya kuchengetedza; kupisa kuchengetedza porcelain mabhora ane kugona kwakanaka kwekushisa uye hazvisi nyore kutyora kana tembiricha ikangoerekana yachinja. Iyo yekupisa yekuchengetedza bhora inonyanya kukodzera kupisa kupisa yekuzadza yekupisa yekuchengetera mweya yekuparadzanisa michina uye iyo blast yevira gasi kudziyisa tirairi yesimbi chirimwa. Iyo yekupisa yekuchengetera bhora inopetenura kupisa kwemweya nemhepo, uye kupisa kwekuchengetedza ceramic bhora kunoita kuti tembiricha yemoto ikurumidze kusvika kune inotenderera simbi kupisa iyo billet. Zvinotarisirwa.

6. Yakakwirira alumina zvedongo Refractory mabhora, yakakwira alumina zvemukati, yakakwira density, yakakwira mehendi simba, yakanaka yekupfeka kuramba, yakadzikama kemikari zvivakwa, yakanakisa kupisa kuramba, yakakwirira alumina zvedongo mabhora anoshandiswa zvakanyanya, uye inogona kushandiswa semakemikari ekuzadza. Yakakwira alumina zvedongo mabhora anogona zvakare kushandiswa sekukuya midhiya. Yakakwira alumina zvedongo Refractory mabhora anoshandiswa zvakanyanya mumakemikari, mehendi, zvemagetsi, kuchengetedzwa kwezvakatipoteredza uye mimwe minda.

1. Yepamusoro-aruminiyamu refractory bhora rinowanzoreva izvo zvemukati zveAl2O3. Iyo yakakurumbira poindi ndeye zvemukati yealuminium oxide mune yakasvibirira bhora rinokanganisa. Iyo aruminiyamu yezvinyorwa inosarudza danho rezvimwe zvakasiyana zvivakwa. Naizvozvo, ndiyo huru yekuita index ye refractory bhora. Yakakwira-aruminiyamu inoratidzira mabhora anogona kuganhurwa mumhando ina maererano neiri aruminiyamu yezvinyorwa: yekutanga-chikamu chepamusoro aruminiyamu yezvinyorwa 75; yechipiri-chikamu chepamusoro-aluminium mabhora, ZN-65 ine 65% yezvigadzirwa zvealuminium; chechitatu-chikamu chepamusoro-aluminium mabhora, ane aruminiyamu zvemukati 55% Iyo ZN-55.

2. Kuwanda kwehuwandu hwehuwandu hwehuwandu hwesimba rakaoma rebhora rinodzora kusvika pahuwandu hwayo, uye iyo unit iri g / cm3. Kuwanda kwehuwandu kunonyanya kuratidza kuumbika kwebhora rinodzora. Kazhinji, huwandu hwehuwandu hwemabhora anokanganisa hwakabatana zvakanyanya nehukama hwavo uye kuumbwa kwemaminera. Mune bhora rinodzora, iko kukwirira kwehuwandu hwehuwandu, zvirinani kunaka kwechigadzirwa. Kuwanda kwehuwandu hwemhando ina dzemabhora anokanganisa ndeaya: giredhi yekutanga yakakwira alumina bhora ≥ 2.5; chechipiri giredhi yakakwirira alumina bhora ≥ 2.3; giredhi yechitatu yakakwirira alumina bhora ≥ 2.1.

3. Iyo inooneka porosity chiyero chevhoriyamu yeakavhurika pores ebhora refractory kune huwandu hwakazara. Kazhinji, iyo slag uye inokuvadza magasi muhovhoni inokanganisa iyo refractory bhora pachayo kuburikidza neakavhurika pores. Naizvozvo, zvinodikanwa kuti iyo inooneka porosity yebhora rinokanganisa idiki sezvinobvira. Iyo inooneka porosity yemhando ina dzeanodzora mabhora ndeaya: yekutanga-nhanho yakakwira-aluminium mabhora≤24%; yechipiri-chikamu chepamusoro-aluminium mabhora≤26%; chechitatu-chikamu chepamusoro-alumina mabhora≤28%.

4. Iko kumanikidza kwekumanikidza kukosha pane tembiricha yemukamuri ine simba rakakura pane kugadzirwa, kutakurwa uye mashandiro mashandiro ebhora rinokanganisa, saka yakakwira yekumanikidza kuramba kukosha kunodiwa. Chikwata chinoratidzwa muKN. Iko kushushikana kwekumanikidza kukosha kwemhando ina dzeanopokana mabhora pane tembiricha yemukati ndeaya: akakosha epamusoro aruminiyamu bhora ≥ 25; giredhi yekutanga yakakwira aluminium bhora ≥ 15; giredhi repiri rakakwira aluminium bhora ≥ 10; giredhi yechitatu yakakwira aluminium bhora ≥ 8.

5. Iyo tembiricha inodzikamisa tembiricha yebhora risingabvumike zvinoreva tembiricha iyo yainokanganisa panguva yekushandisa. Iyo yekuremerwa inodzikamisa tembiricha yemhando ina dzeanodzora mabhora ndeaya: akakosha-giredhi yakakwira-aluminium mabhora ≥1530 ℃; yekutanga-giredhi yakakwira-aluminium mabhora ≥1480 ℃; yechipiri-giredhi yakakwira-aluminium mabhora ≥1450 ℃; uye yechitatu-giredhi yakakwira-aluminium mabhora ≥1400 ℃.

6. Thermal kukatyamara kugadzikana ndiko kugona kweiyo Refractory bhora kuramba tembiricha shanduko mukukurumidza kutonhora uye nekukurumidza kupisa. Kuyera iyi indekisi yekuita yebhora refractory, inowanzo kuratidzwa muhuwandu hwenguva pasi pechimiro che1100 – kutonhora kwemvura. Iyo yekupisa yekuvhunduka kugadzikana kwemhando ina dzeanopokana mabhora ndeaya: akakosha epamusoro alumina bhora ≥ kagumi; giredhi yekutanga yakakwira alumina bhora, yechipiri giredhi yakakwirira alumina bhora, uye chechitatu giredhi yakakwira alumina bhora ≥ ka10.
