Brick na Silica don Coke Oven
Brick na Silica don Coke Oven
Yana amfani: ana amfani dashi da yawa a cikin masu gyara tanda na coke, chute da ɗakunan ƙonewa
Tubalan siliki galibi kayan ƙin acid ne waɗanda suka haɗa da tridymite, cristobalite da ƙaramin adadin ma’adini da matakan gilashi.
Features:
Abubuwan silica sun wuce 94%. Hakikanin gaskiya shine 2.35g/cm3. Yana yana da juriya ga acid slag yashewa. Ƙarfin ƙarfin zafin zafin da ya fi girma, fara zafin zafin kayan aiki shine 1620 ~ 1670 ℃. Ba zai lalace ba bayan amfani na dogon lokaci a babban zazzabi. Ƙarancin kwanciyar hankali na zafi (1 ~ 4 sau na musayar zafi a cikin ruwa) Ana amfani da siliki na halitta azaman kayan abu, kuma ana ƙara adadin ma’adinai don inganta juzu’in ma’adini a cikin koren jiki zuwa phosphorite. Sannu a hankali an harba shi a 1350 ~ 14 30 ℃ ƙarƙashin rage yanayi. Lokacin zafi zuwa 1450 ℃, za a sami kusan 1.5 ~ 2.2% na jimlar faɗaɗa girma. Wannan faɗaɗawar sauran zai sa haɗin gwiwa da aka yanke da ƙarfi kuma tabbatar da cewa masonry yana da ƙoshin iska mai kyau da ƙarfin tsari. A lokaci guda, yana da fa’idodin tsawon rayuwar sabis da rage yawan kuzarin makamashi.
