Suufka dhoobada ah ee foornada kululaynta

Dhogorta dhoobada ah waxaa laga sameeyaa dhalaalinta dhoobada saafiga ah ee sare leh, budada alumina, budada silica, ciidda chromite iyo walxo kale oo cayriin ah foornada korontada ee warshadaha heerkulka sare. Kadib isticmaal hawo la cadaadiyey si aad u afuufto ama mashiinka wareejiso si aad u wareejiso walxaha ceeriin ee dhalaalay qaab faybar ah, oo aad u ururiso faybarka iyada oo loo marayo ururin dhogor ah oo fiber ah si aad u samayso dhogorta dhoobada ah. Dhogorta dhoobada ah waa walxo dahaadh kuleyl oo waxtar sare leh, kaas oo leh astaamo miisaan fudud, xoog sare, iska caabin oksaydh wanaagsan, dabacsanaan kuleyl oo hooseeya, dabacsanaan wanaagsan, iska caabin daxal wanaagsan, awood kuleyl oo hooseeya iyo dahaar cod oo wanaagsan. Kuwa soo socdaa waxay sharraxayaan isticmaalka dhogorta dhoobada ah ee foornada kululaynta:

(1) Marka laga reebo qiiqa, marinnada hawada iyo salka foornada, bustayaasha dhogorta dhoobada ah ama qaybaha dhogorta dhoobada ah ayaa loo isticmaali karaa qaybaha kale ee foornada kululaynta.
(2) Bustaha dhogorta dhoobada ah ee loo isticmaalo dusha sare ee kulul waa inuu ahaadaa buste irbad lagu dhuftay oo dhumucdiisu tahay ugu yaraan 25mm iyo cufnaan dhan 128kg/m3. Marka loo isticmaalo fiilada dhoobada ah ama loox lakabka dusha sare ee kulul, dhumucdiisu waa inaysan ka yarayn 3.8cm, cufnaantuna waa inaysan ka yarayn 240kg/m3. Suufka dhoobada ah ee lakabka dambe waa buste irbad lagu dhuftay oo cufnaan badan leh ugu yaraan 96kg/m3. Tilmaamaha fiilada dhoobada ah ama loox lakabka dusha sare ee kulul: marka heerkulka dusha sare ee kulul uu ka hooseeyo 1095℃, cabbirka ugu badan waa 60cm × 60cm; marka heerkulka dusha sare ee kulul uu ka badan yahay 1095℃, cabbirka ugu badan waa 45cm × 45cm.
