Kufotokozera Mwatsatanetsatane
The mchere zikuchokera njerwa dongo makamaka kaolinite (Al2O3 · 2SiO2 · 2H2O) ndi 6% ~ 7% zonyansa (potaziyamu, sodium, calcium, titaniyamu, chitsulo oxides). Kuwotcha kwa njerwa zadongo makamaka ndi njira ya kaolinite yowonongeka ndi kupanga makristasi a mullite (3Al2O3 · 2SiO2) kupyolera mu kutaya madzi m'thupi mosalekeza. Panthawi yowombera, SiO2 ndi Al2O3 mu njerwa zadongo zimapanga eutectic low-melting silicates ndi zonyansa, zomwe zimazungulira makristasi a mullite.
Njerwa zomangira dongo zimagawidwa kukhala njerwa zadongo zopangira ng'anjo zophulika, njerwa zadongo zopangira ng'anjo zotentha, ndi njerwa zazikulu zadongo zowotchera magalasi malinga ndi ntchito zawo.
Njerwa zadongo zopangira ng'anjo zophulika
Njerwa zadongo zopangira ng'anjo zophulika ndi njerwa zadongo zopangidwa ndi dongo losasunthika ngati zida zopangira ndipo zimagwiritsidwa ntchito pomanga ng'anjo yoyaka moto. Njerwa zadongo zopangira ng'anjo zophulika zimagwiritsidwa ntchito pammero, thupi, moto, pansi pa ng'anjo yaing'ono yophulika ndi thupi la ng'anjo zazikulu zophulika.
Dongo refractory njerwa kwa ng'anjo kuphulika amafuna mkulu refractory mphamvu kutentha firiji ndipo akhoza kukana ntchito yaitali ndi kuvala mlandu; kuchepa kwa voliyumu yaying'ono pansi pa kutentha kwakukulu ndi kugwira ntchito kwa nthawi yaitali, zomwe zimathandiza kusunga umphumphu wazitsulo; kutsika kowoneka bwino komanso Fe:O. Zochepa, kuchepetsa mpweya wa carbon mu pores, kupewa kukulitsa ndi kumasula njerwa zowonongeka pakagwiritsidwa ntchito ndi kuwonongeka; zinthu zochepa zosungunuka zimapangidwira. Njerwa zadongo zopangira ng'anjo zophulika zimagwira ntchito bwino kuposa njerwa zadongo wamba. [2]
Njerwa zadongo zopangira ng'anjo zoyaka moto
Njerwa zadothi zopangira ng'anjo zotentha zimapangidwa ndi dongo losasunthika ndipo zimagwiritsidwa ntchito popanga ng'anjo yoyaka moto. Njerwa zadongo zopangira ng'anjo zotentha zotentha zimagwiritsidwa ntchito m'ng'anjo zamoto, zipinda zosungiramo kutentha ndi makoma ogawa. Njerwa zadongo zopangira ng'anjo zowotcha zimafunika kuti zikhale ndi mphamvu yolimbana ndi kutenthedwa kwa kutentha, kutentha kwakukulu kofewetsa komanso kukwapula pang'ono.
China 3) Dongo refractory njerwa kwa ng'anjo otentha kuphulika amagawidwa m'makalasi atatu malinga ndi zizindikiro thupi ndi mankhwala: RN-42, RN-40 ndi RN-36. Zizindikiro zakuthupi ndi zamankhwala komanso kulolerana kowoneka bwino ndi izi:
(1) Pamene wosanjikiza mng'alu m'lifupi si wamkulu kuposa 0.25mm, kutalika si malire;
(2) Pamene wosanjikiza mng'alu m'lifupi ndi 0,26-0. 50mm, kutalika si wamkulu kuposa 30mm;
(3) Pamene wosanjikiza mng'alu m'lifupi ndi wamkulu kuposa 0.50mm, ndi wosayenerera. [3]
Njerwa zazikulu zadongo zowotchera magalasi
Njerwa zazikulu zadongo zowotchera magalasi ndi njerwa zadongo zowunira magalasi zolemera mayunitsi osachepera 50kg zomwe zimagwiritsidwa ntchito pomanga ng'anjo zamagalasi.
