Ayyukan samarwa ya nuna cewa mahimmancin barbashi na bulo na silica na yau da kullun shine 2 ~ 3mm, kuma lokacin da ake amfani da ma’adini na jijiya azaman albarkatun ƙasa, matsakaicin girman barbashi shine kusan 2mm.

Halayen gyare-gyare na tubalin silica sun fi nunawa a cikin bangarori uku: halayen gyare-gyare na blank, da hadadden siffar tubali da babban bambanci a cikin inganci guda ɗaya.

Silicon billet ƙananan kayan filastik ne, don haka ya kamata a ƙara matsa lamba na gyare-gyare yadda ya kamata. Tubalin siliki na Coke oven suna da sifofi masu rikitarwa, nauyi ɗaya, wasu kuma suna da kauri na 160mm, don haka yana da kyau a yi amfani da gyare-gyaren gefe biyu. Idan an karɓi hanyar yin ƙirar girgiza, fa’idodinsa sun fi bayyane. Tubalin siliki za su faɗaɗa ƙarar lokacin da aka kora su, don haka ya kamata a rage girman ƙirar bulo daidai.

Bulo na siliki zai fuskanci canjin lokaci yayin aikin harbe-harbe, wanda ke kawo matsaloli ga harbe-harbe. Don haka, ya kamata a yi la’akari sosai da yadda ake canza yanayin jiki da sinadarai na jikin murhu, da siffa da girman jikin da ba shi da lahani, da kuma sifofin jikin kiln da kyau.
