Kana inopisa blast furnace iri kushanda, iyo insulation ceramic board yechoto lining inobatwa nekuchinjika kwakasimba kwekushisa panguva yekupisa kwekuchinjana, kukukurwa kwekemikari kweguruva kunounzwa nekuputika kwevira regasi, mechanical load, uye kukukurwa kwegasi rinopisa. Zvikonzero zvikuru zvekukuvadzwa kwekupisa blast furnace lining ndezvi:
(1) Kushushikana kwekushisa. Paunenge uchipisa moto unopisa moto, tembiricha yekamuri yekupisa yakakwira zvakanyanya, uye tembiricha yechoto yepamusoro inogona kusvika 1500-1560 ℃. Kupisa zvishoma nezvishoma kunoderera kubva kumusoro kwechoto pamwe chete nemadziro echoto uye cheki zvidhinha; Munguva yekupihwa kwemhepo, mhepo inotonhora inotonhorera inovhuvhuta kubva pasi peiyo regenerator uye zvishoma nezvishoma inopisa. Sezvo chitofu chinopisa chinopisa chinogara chichipisa uye chichipa mhepo, jira rekupisa rinopisa uye zvidhinha zvecheki zvinowanzoita kukurumidza kutonhora uye kupisa, izvo zvinoita kuti masonry iparadze uye peel.
(2) Kuora kwemakemikari. Iro gasi remarasha uye kupisa kunotsigira mhepo ine humwe huwandu hwealkaline oxides. Madota mushure mekupisa ane 20% iron oxide, 20% zinc oxide uye 10% alkaline oxides. Zvizhinji zvezvinhu izvi zvinobudiswa kunze kwechoto, asi zvishomanana zvacho zvinonamatira pamusoro pemuviri wechoto uye kupinda mukati mechidhinha chechoto. Nokufamba kwenguva, simbi yekubikira yesimbi ye ceramic ndiro uye zvimwe zvimiro zvichakuvadzwa, kudonha, uye simba richaderedzwa.
Nyaya inotevera tichaenderera mberi nekuzivisa zvikonzero zvekukuvadzwa kweinsulation ceramic boardye hot blast furnace lining. Ndapota ramba wakatarisa!
