Refractory Castable
Mafotokozedwe Akatundu
Refractory castablesndi osakaniza refractory aggregates, ufa ndi binders. Mukathira madzi kapena zakumwa zina, ndizoyenera kumanga pothira ndi kugwedera. Atha kupangidwanso m'magawo opangidwa kale ndi mawonekedwe odziwika ndi makulidwe ake pomanga ng'anjo yamoto yamafakitale. Pofuna kupititsa patsogolo thupi ndi mankhwala katundu ndi ntchito yomanga ya castables refractory, mlingo woyenera wa admixtures nthawi zambiri anawonjezera, monga plasticizers, dispersants, accelerators, retarders, wothandizila kukula, debonding-gelling wothandizira, etc. Komanso, kwa castables refractory ntchito m'madera ndi mphamvu makina kapena amphamvu matenthedwe kuchuluka kwa zinthu CHIKWANGWANI anawonjezera, ngati zitsulo matenthedwe kugwedezeka ndi kugwedezeka. kuchuluka kwambiri. Mu insulating refractory castable, ngati organic ulusi anawonjezera, izo osati kumapangitsanso kulimba, komanso kuthandiza kusintha matenthedwe kutchinjiriza katundu. Popeza zofunika zikuchokera zinthu castables refractory (monga aggregates ndi ufa, admixtures, binders ndi admixtures), coagulation ndi kuumitsa ndondomeko, njira zomangamanga, etc., ndi ofanana ndi konkire mu zomangamanga zomangamanga, poyamba ankatchedwakonkriti wonyezimira.

Kugwiritsa ntchito
1. Aluminiyamu yapamwamba kwambiri:Zotayidwa zapamwamba za aluminiyamu zimapangidwa makamaka ndi alumina (Al2O3) ndipo zimakhala zolimba kwambiri, kukana kwa slag komanso kukana kugwedezeka kwamafuta. Amagwiritsidwa ntchito kwambiri m'ng'anjo zotentha kwambiri komanso m'malo opangira zitsulo, zitsulo zopanda chitsulo, mankhwala ndi mafakitale ena.
2. Chitsulo CHIKWANGWANI kulimbikitsa castable:Chitsulo chachitsulo chokhazikika chokhazikika chimakhazikitsidwa pazitsulo wamba ndipo ulusi wachitsulo umawonjezedwa kuti uwonjezere kukana kwake kwa kutentha, kukana kuvala komanso kukana kwa slag. Amagwiritsidwa ntchito kwambiri mu ng'anjo, pansi pa ng'anjo ndi mbali zina muzitsulo, zitsulo, petrochemical ndi mafakitale ena.
3. Mullite castable:Mullite castable imapangidwa makamaka ndi mullite (MgO · SiO2) ndipo imakhala yabwino kukana kuvala, kukana komanso kukana kwa slag. Amagwiritsidwa ntchito kwambiri m'magawo ofunikira monga ng'anjo zopangira zitsulo ndi zosinthira muzitsulo, zitsulo ndi mafakitale ena.
4. Silicon carbide castable:Silicon carbide castable imapangidwa makamaka ndi silicon carbide (SiC) ndipo imakhala ndi kukana kwamphamvu kwambiri, kukana kwa slag komanso kukana kugwedezeka kwamafuta. Amagwiritsidwa ntchito kwambiri m'ng'anjo zotentha kwambiri, mabedi a ng'anjo ndi mbali zina zazitsulo zopanda chitsulo, mankhwala, ceramics ndi mafakitale ena.
5. Zoponyera simenti zochepa:amatanthauza zoponyedwa zokhala ndi simenti yochepa, zomwe nthawi zambiri zimakhala pafupifupi 5%, ndipo zina zimachepetsedwa mpaka 1% mpaka 2%. Makapu a simenti otsika amagwiritsa ntchito tinthu tating'onoting'ono tosapitilira 1μm, ndipo kukana kwawo kutenthedwa kwamafuta, kukana kwa slag ndi kukana kukokoloka kumakhala bwino kwambiri. Otsika simenti castables ndi oyenera linings ng'anjo zosiyanasiyana kutentha kutentha, ng'anjo kutentha, kilns ofukula, kilns rotary, ng'anjo yamagetsi chimakwirira, kuphulika ng'anjo pogogoda mabowo, etc.; zodzikongoletsera otsika-simenti castables ndi oyenera ophatikizikapo kutsitsi mfuti linings kwa kutsitsi zitsulo, mkulu kutentha kuvala zosagwira linings kwa petrochemical catalytic akulimbana reactors, ndi linings akunja Kutentha ng'anjo madzi kuzirala mapaipi.
6. Zomangira zosamva kuvala:Zigawo zazikulu za ma castables osagwirizana ndi kuvala amaphatikiza zophatikizika, ufa, zowonjezera ndi zomangira. Kuvala zosagwira refractory castables ndi mtundu wa zinthu amorphous refractory chimagwiritsidwa ntchito zitsulo, petrochemicals, zomangira, mphamvu ndi mafakitale ena. Nkhaniyi ili ndi ubwino wokana kutentha kwambiri, kukana kuvala, ndi kukana kukokoloka. Amagwiritsidwa ntchito kukonzanso ndi kuteteza zingwe za zipangizo zotentha kwambiri monga ng'anjo ndi ma boilers kuti awonjezere moyo wautumiki wa zipangizozo.
7. Ladle castable:Ladle castable ndi amorphous refractory castable zopangidwa ndi apamwamba aluminiyamu bauxite clinker ndi pakachitsulo carbide monga zipangizo zazikulu, ndi koyera aluminiyamu simenti binder, dispersant, shrinkage-umboni wothandizira, coagulant, CHIKWANGWANI kuphulika-umboni ndi zina zina. Chifukwa imakhala ndi zotsatira zabwino pagawo logwira ntchito la ladle, imatchedwanso aluminium silicon carbide castable.
8. Opepuka insulatory refractory castable:Opepuka insulating refractory castable ndi refractory castable yokhala ndi kulemera kopepuka, mphamvu yayikulu komanso magwiridwe antchito abwino kwambiri amafuta. Amapangidwa makamaka ndi ma aggregates opepuka (monga perlite, vermiculite, etc.), zinthu zokhazikika zotentha kwambiri, zomangira ndi zowonjezera. Amagwiritsidwa ntchito kwambiri pazida zosiyanasiyana zamafakitale zotentha kwambiri, monga ng'anjo zamafakitale, ng'anjo zotenthetsera kutentha, ng'anjo zachitsulo, ng'anjo zosungunula magalasi, ndi zina zotero, kupititsa patsogolo mphamvu zogwiritsira ntchito mphamvu ndi kuchepetsa mphamvu.
9. Corundum castable:Ndi ntchito yake yabwino kwambiri, corundum castable yakhala chisankho choyenera pazigawo zazikulu za ma kilns otentha. Makhalidwe a corundum castable ndi mphamvu zambiri, kutentha kwakukulu kofewetsa katundu ndi kukana kwa slag, etc. Kutentha kwa ntchito ndi 1500-1800 ℃. pa
10. Magnesium otayidwa:Amagwiritsidwa ntchito kwambiri pazida zotentha kwambiri, amalimbana kwambiri ndi dzimbiri za alkaline slag, index yotsika ya okosijeni komanso osaipitsa chitsulo chosungunuka. Choncho, ali ndi chiyembekezo chochuluka chogwiritsira ntchito makampani opanga zitsulo, makamaka pakupanga zitsulo zoyera ndi mafakitale opangira zipangizo zomangira. pa
11. Dongo loponyedwa pansi:Zigawo zikuluzikulu ndi dongo clinker ndi dongo kuphatikiza, ndi zabwino matenthedwe bata ndi zina refractoriness, ndipo mtengo ndi otsika. Nthawi zambiri amagwiritsidwa ntchito pazitsulo za ng'anjo zamagulu ambiri, monga ng'anjo zowotcha, ng'anjo zowotchera, ma boilers, ndi zina zotero. Ikhoza kupirira kutentha kwina kwa kutentha kwa kutentha ndikugwira nawo ntchito yotetezera kutentha ndi kuteteza thupi la ng'anjo.
12. Dry castables:Zowuma zowuma zimapangidwa makamaka ndi zophatikizika, ufa, zomangira ndi madzi. Zosakaniza zodziwika bwino zimaphatikizapo clay clinker, tertiary alumina clinker, ultrafine powder, CA-50 simenti, dispersants ndi siliceous kapena feldspar impermeable agents.
Zowuma zowuma zimatha kugawidwa m'mitundu yambiri malinga ndi momwe amagwiritsidwira ntchito komanso zopangira. Mwachitsanzo, ma castables owuma osasunthika amagwiritsidwa ntchito makamaka m'maselo a aluminiyamu a electrolytic, omwe amatha kulepheretsa kulowa kwa ma electrolyte ndikukulitsa moyo wautumiki wa maselo. Komanso, youma refractory castables ndi oyenera hardware, smelting, makampani mankhwala, zitsulo sanali achitsulo ndi mafakitale ena, makamaka mu makampani zitsulo, monga rotary uvuni kutsogolo ng'anjo pakamwa, azingokhala ng'anjo, ng'anjo mutu chivundikiro ndi mbali zina.
