Clay zvidhinha zvinopesana nokuda kwemoto unopfuta

Clay refractory zvidhinha zve blast furnaces inofanira kugadzirwa nevhu refractory yemucheka wekuputika kwevira madziro. Clay refractory zvidhinha zve blast furnaces anoshandiswa pahuro, shaft, hearth, pasi pediki blast furnace lining uye muchoto wechoto chemoto mukuru.

Clay refractory zvidhinha zve blast furnace inoda kusimba kwepamusoro kwezvimisikidzo zvisingatsva nemoto patembiricha yekamuri, izvo zvinogona kuramba kukuvadzwa kwebasa kwenguva refu kwezvinhu zvakashandiswa zvakare; diki vhoriyamu shrinkage pasi pebasa renguva refu pakupisa kwakanyanya kunobatsira kuchengetedza kunzwisisika kwebindu rechoto; yakaderera inooneka porosity uye Fe:O. Iyo yakaderera mvura yemukati inogona kuderedza kuunganidzwa kwekabhoni chirimwa mugomba remhepo uye kudzivirira zvidhinha zvinoramba kubva pakuzvimba uye kusunungura uye kuparadzwa panguva yese yekushandisa; zvinhu zvakaderera zvinonyungudika zvinogadzirwa zvishoma. Clay refractory zvidhinha zve blast furnaces zvine zvivakwa zviri nani pane zvakajairika zvidhinha zvevhu.

The cross-section spallation yevhu refractory zvidhinha zve blast furnaces ine zvinodiwa:

(1) Kana hupamhi hwese hwe spall husingapfuuri 0.25mm, kureba hakuna kukwana;

(2) Kana iyo yese spall hupamhi iri 0.26 ~ 0.5mm, kureba hakufanirwe kudarika 15mm;

(3) Kana hupamhi hwese spall hunopfuura 0.50mm, inorambidzwa.

Iwo ma-cross-sectional cracks evhu refractory zvidhinha ane zvinodiwa:

(1) Kana hupamhi hwese hwe spall husingapfuuri 0.25mm, kureba hakuna kukwana;

(2) Kana iyo yese spall hupamhi iri 0.26 ~ 0.50mm, kureba hakufanirwe kudarika 40mm;

(3) Spalling inorambidzwa kana huwandu hwese hunopfuura 0.5mm.
