Menene abubuwan da ke haifar da lalacewa tubali masu ratsa jiki?

1. Abubuwan sinadaran

1. Harin sinadari na narkakkar slag (ciki har da harin sinadari na narkakkar kurar tanderu). Gabaɗaya, shine babban abin da ke haifar da lalatawar rufin bulo mai jujjuyawa na tanderun da ke narkewa.

2. Chemical lalata na makera gas. Galibi yana nufin lalatawar iskar oxygen a hankali a cikin iskar iskar tanderu mai zafi a babban zafin jiki.

3. Chemical lalata tsakanin tubali refractory. Idan tubalin acidic da alkaline refractory sun haɗu tare, za a samar da mahaɗan fusible a wurin tuntuɓar a babban zafin jiki, yana haifar da lalacewa a lokaci guda.

4. Electrochemical yashewa. Anode (zinc) na baturin jan karfe-zinc. Ci gaba da kasancewa oxidized da lalata, ka’idar electrochemical yashwa na carbon refractory tubalin iri daya ne. A cikin tanda mai zafi mai zafi (irin su masu canza ƙarfe na iskar oxygen), lokacin da tubalin da ke ɗauke da carbon (kamar tubalin da aka ɗaure) aka haɗa su da sauran bulogin da ke da ƙarfi, ana iya samun batura. Narkakken slag yana daidai da electrolyte, kuma bulo mai ɗauke da carbon ɗin ya zama anode, kuma bulo mai jujjuyawar ya lalace saboda iskar oxygen.

2. Abubuwan jiki

1. Fatsawa na tubalin da ke hana ruwa gudu sakamakon canje-canje masu tsauri a yanayin zafi.

2. Yawan narkewar zafin jiki wanda ya haifar da yawan zafin jiki.

3. Reheating shrinks ko faɗaɗa, haifar da lalacewa ga tanderun jiki da kuma rage sabis rayuwa na refractory tubalin.

4. Ba daidai ba tanda, dumama mai yawa, wuce kima thermal fadada, halakar da tanderun jiki da kuma rage rayuwar refractory tubalin.

5. Ƙarfe na ruwa yana shiga cikin tubalin da ke daɗaɗawa ta hanyar raƙuman bulo na bulo na bulo, ko kuma ya shiga cikin ɓangarorin tubalin, kuma bayan ƙaddamarwa cikin yanayi mai ƙarfi, ƙarar yana faɗaɗa kuma ana haifar da damuwa, wanda ke hanzarta tsagewar tubalin. tubali.

Uku, abubuwan inji

1. Lokacin da aka ƙara kayan aiki, musamman ma kayan ƙarfe mai nauyi, tasirin injin akan ƙasan tanderun da bangon tanderun shine muhimmin dalilin fashewar bulo.

2. Ruwan karfen ruwa (kamar motsin narkakkar narkakkar wutar lantarki a cikin tanderun narkewa) yana haifar da lalacewa na inji a saman rufin tanderun na ciki.

3. Rufin wutar lantarki mai zafi ya lalace saboda tsananin ƙarfin da ya wuce kima, wanda ke haifar da gefen ciki na tubali mai raguwa don yin laushi da lalacewa.
