Nzira dzekudzikisa corrosion mutengo we refractory lining muchoto
Kuburikidza nehuwandu hukuru hweslag kuramba bvunzo yekutsvagisa uye kushanda chaiko kweshanduko, imwe ruzivo rwekupokana kwekupokana kwerefractory linings inogona kuwanikwa:
(1) Kuumbwa kwesimbi yakanyungudutswa kune zvakakosha pahupenyu hweiyo refractory lining, zviri mukati mesilicon, sango, uye sarufa.
(2) Kunyanya kupisa kwekupedzisira kweshanduko kunotungamira mukudzikira kwehupenyu hwebiravira rechoto. Kana tembiricha yekupedzisira iri pamusoro pe1700 ° C, kuwedzera kwe10 ° C kuchawedzera zvakanyanya kukora kweiyo refractory lining yechoto.
(3) Kuwedzera alkalinity ye slag inobatsira kuderedza kuparara kwe slag kune yekutanga refractory.
(4) Kuwedzera iyo Mg0 yemukati mune slag inogona kuderedza kukora kweiyo slag pane refractory lining yevira.
(5) Kuwedzera iyo Fe0 yemukati mune slag kuchaita kuti kuonda kweiyo refractory zvinhu zvechoto chemoto kuwedzere.
(6) Muchikamu chekutanga chekushandura kushandura, nheyo ye slag inenge yakaderera, uye jira racho rakasvibiswa zvakanyanya. Dolomite slag inofanirwa kushandiswa kugadzira iyo Mg0 zvirimo muslag padyo nenzvimbo yakaguta.
(7) Fluorite zvakare inoshatisa tambo yevira, saka huwandu hwefluorite hwakawedzerwa hunofanira kudzikiswa zvakanyanya sezvinobvira.
(8) Pakati pe dolomite uye magnesia dolomite refractories, Mg0 ine zviri nani slag erosion resistance pane Ca0, asi kuvapo kweCa0 kunogona kuvandudza kupisa kwepamusoro kwe thermoplasticity uye slag kupindira kupikisa kwe refractories.
(9) Zvigadzirwa zvesimbi yekubikira refractories zvinodiwa kuti zvive nekuchena kwepamusoro. Semuenzaniso, magnesium dolomite jecha inoda kusvibiswa kwakakwana kweSiO2 + A12O3 + FeO pasi pe3%; zvimwe zvakadai semagnesia yakasanganiswa, graphite, nezvimwewo vanewo zvinodiwa zvakafanana.
