Kusiyana pakati pa ramming material ndi refractory castable

Kodi pali kusiyana kotani pakati pa refractory ramming material ndi refractory castable? Choyamba, zinthu ziwirizi zimagawidwa ngati zida zosasinthika zosasinthika. Refractory ramming material ndi njira yomanga yomwe imagwiritsa ntchito ramming ndipo imaumitsidwa ndi kutentha. Refractory castable ndi njira yomanga yothira, yomwe imatha kuumitsa popanda kutentha. Kodi pali kusiyana kotani pakati pa refractory ramming material ndi refractory castable? Kusiyana kwagona pa njira yomanga ndi kuumitsa. Chonde onani tsatanetsatane pansipa.

Tanthauzo la ramming ndi kuthira

1. Zida zomangira ramming, kusakaniza zomangira zomangira pamalopo, pogwiritsa ntchito chotola cha pneumatic kapena ramming yamakina, kukakamiza kwa mphepo sikuchepera 0.5MPa. Ziwalo zokhala ndi zinthu zochepa kapena zosafunikira kugwiritsa ntchito zimathanso kumangidwa ndi dzanja. Amapangidwa ndi kusakaniza refractory aggregates, ufa, binders, admixtures ndi madzi kapena zakumwa zina ndi gradation. Chifukwa chake, zomangira zomangira zomangira komanso zokanira zimakhala ndi chinyezi chochepa, mfundo zothina komanso zimagwira ntchito bwino kuposa zotayira komanso zokanira zazinthu zomwezo. The kuipa refractory refractory ramming zipangizo ndi wosakwiya kumanga liwiro ndi mkulu ntchito mwamphamvu, ndipo pali chizolowezi m’malo ndi youma kugwedera zipangizo ndi apamwamba refractory refractory castables.

2. Refractory castables. Zowonongeka zoponyedwa nthawi zambiri zimaponyedwa, kugwedezeka kapena kujambulidwa pamalo omwe amagwiritsidwa ntchito, ndipo amathanso kupangidwa kukhala ma preform kuti agwiritsidwe ntchito.

Ntchito ndi magulu

Kodi pali kusiyana kotani pakati pa zida za ramming ndi refractory castables? Refractory castables ali ndi madzi ochulukirapo ndipo amagwiritsidwa ntchito kwambiri. Magawo okhala ndi zida zomangira zocheperako kapena zosafunikira amathanso kumangidwa ndi dzanja. Zida zopangira ramming zimagawidwa molingana ndi zopangira: alumina yapamwamba, dongo, magnesia, dolomite, zirconium ndi silicon carbide-carbon refractory ramming zida. Refractory castables amagawidwa malinga ndi zipangizo: 1. Malinga ndi porosity, pali mitundu iwiri ya wandiweyani refractory castables ndi matenthedwe kutchinjiriza zipangizo refractory ndi porosity osachepera 45%; 2. Malingana ndi binder, pali ma hydraulic bonding ndi kugwirizana kwa mankhwala. , Condensation kuphatikiza ndi refractory refractory castables.

Refractory castable ndi refractory yopanda mawonekedwe yomwe imapangidwa ndikugwiritsidwa ntchito kwambiri. Amagwiritsidwa ntchito kwambiri popanga mitundu yonse ya ng’anjo yamoto yotenthetsera ndi zina. Amagwiritsidwa ntchito kwambiri muzitsulo, mafuta, mankhwala, zomangira, mphamvu zamagetsi, makina opangira makina opangira makina ndi zida zotenthetsera, komanso zinthu zamtengo wapatali zingagwiritsidwenso ntchito pophunzitsa ng’anjo.

Refractory ramming material ndi zinthu zambiri zopangidwa ndi silicon carbide, graphite, ndi calcined anthracite yamagetsi ngati zida zopangira, zosakanikirana ndi mitundu yosiyanasiyana ya zowonjezera ufa wa ultrafine, ndi simenti yosakanikirana kapena utomoni wophatikizika ngati chomangira. Amagwiritsidwa ntchito kudzaza kusiyana pakati pa zida zoziziritsira ng’anjo ndi zomangira kapena zomangira zosanjikiza zomangira. Zida zolimbana ndi moto zimakhala ndi kukhazikika kwa mankhwala, kukana kukokoloka, kukana abrasion, kukana kukhetsa, komanso kukana kutentha. Amagwiritsidwa ntchito kwambiri muzitsulo, zomangira, maphunziro azitsulo zopanda chitsulo, makampani opanga mankhwala, makina ndi ntchito zina zopanga.
