Babban tubalin arc na duniya

Babban tubalin ƙarfe na ƙarfe na aluminium abu ne mai tsayayya da tsaka tsaki, wanda zai iya tsayayya da lalata gurɓataccen acidic slag da alkaline slag. Saboda yana ƙunshe da SiO2, ikonsa na yin tsayayya da slag na alkaline yana da rauni fiye da na slag acidic. Bugu da ƙari, juriya na slag na samfuran alumina ma yana da alaƙa da kwanciyar hankali na samfuran a cikin slag. Gabaɗaya magana, bayan ƙwanƙwasa babban matsin lamba da harbe-harben zazzabi mai zafi, samfuran da ke da ƙananan porosity suna da juriya mafi girma.

Arc na tubalin arc na duniya shine semicircle, ɗayan ƙarshen shine tsagi. Komai kaurinsa, zai kasance mai sassauƙa da motsi. Saboda ba shi da ginshiƙi kuma yana da ɗan jujjuyawar girma, ana kuma iya gina shi cikin da’irar. Don haka ake kira arc na duniya, ana amfani da irin wannan tubalin a cikin ladle. A duniya baka high alumina refractory tubali ne yafi amfani a matsayin ciki rufi na karfe guga. Da farko yumbu ne. Yanzu sannu a hankali ana maye gurbinsa da babban tubalin alumina. Babban tubalin alumina na arc na duniya shine silicate na aluminium tare da abun alumina fiye da 48%. Inganci mai rikitarwa. An kafa shi kuma an ƙera shi daga bauxite ko wasu albarkatun ƙasa tare da babban abun ciki na alumina. Babban kwanciyar hankali na zafi, ƙanƙantar da kai sama da 1770 ℃. Tsarin juriya ya fi kyau.

An yi amfani da tubalin ƙirar arc na duniya gabaɗaya azaman rufin ladle. Da farko yumbu ne, amma yanzu sannu a hankali ana maye gurbinsa da manyan tubalin alumina. Dangane da yanayin amfani, mun yi imani cewa tubalin baka na duniya yana da fa’idodi masu zuwa:

1. Ƙarfin ƙarfi mai ƙarfi da juriya abrasion a zafin jiki na ɗaki. Kyakkyawan juriya na sunadarai, musamman slag acidic. Babban zazzabi mai saurin zazzabi yana da ƙanƙanta. Excellent anti-stripping performance.

2. Hanyoyin lanƙwasawa na iya motsawa da yardar kaina kuma suna iya komawa da baya don daidaita zagaye yayin sanya tubalin, don haka yana da kyau a gina tubalin da ba zai yuwu ba, kuma gibin tubalin zai iya kaiwa 1 mm gaba ɗaya. An rage kaurin bulo mai rufi, kuma ana ƙara ƙarfin ƙarfin gangar ƙarfe daidai.

3. Haɗin kai tsaye na bulo na arc na duniya ƙanana ne, wanda ya kai 70% ƙasa da madaidaiciyar haɗin keɓaɓɓun tubalin ƙyalli, wanda ke rage amfani da laka mai ƙima kuma yana adana farashin abubuwan amfani. Za’a iya daidaita girman zuwa kowane tsayin.

3. Tsawon rayuwar sabis, tare da ƙarin tubalin yumɓu na clinker ya ƙaru da 210%.

4. Daga rage yawan amfani da maganin naúrar, hakanan yana nuna fifikon arc na duniya mai girman aluminium. Kuma rage yawan amfani da naúrar na iya yin bayanin ragin da ya dace na abubuwan da ba na ƙarfe ba a cikin narkakken ƙarfe.

5. Bayan ci gaba da amfani, duba cewa juriya ta lalata sashe na babban tubalin alumina mai ƙarfi zuwa ƙyallen da keɓaɓɓen ƙarfe ya fi na bulo mai yumɓu mai yawa.

6. Ana iya amfani da bulo mai ƙyalli na arc na duniya idan ana yin bulo saboda zagaye a ƙarshen duka. Komawa gaba da baya don daidaita zagaye, don haka yana da kyau a gina tubalin da ba zai yuwu ba, kuma raunin bulo na iya kaiwa 1 mm gaba ɗaya.

7. Haɗin kai tsaye na tubalin arc na duniya ya fi ƙanƙanta, wanda shine 70% ƙasa da madaidaiciyar haɗin keɓaɓɓun tubalin ƙyalli, don haka lalacewar lalacewar narkakken baƙin ƙarfe yana motsawa sama da ƙasa da zurfi a cikin gandunan tubalin shine gyara.

8. Saboda inganta ingancin tubalin da ya hana, za a iya rage kaurin bulo na rufi, kuma ana iya ƙara ƙarfin gangar ƙarfe daidai gwargwado.

9. Saboda tsawon rayuwar sabis da yin bulo mai dacewa, aikin rage gangunan ƙarfe a bayan tanderu yana ƙaruwa kuma yawan amfani da ganga na ƙarfe yana ƙaruwa.
