Njerwa za Flow Steel
Mafotokozedwe Akatundu
Njerwa zachitsulo zoyendatchulani njerwa zosanjikizana zomwe zimayalidwa m'mizere ya mbale ya pansi kuti ilumikizane ndi njerwa zachitsulo ndi nkhungu ya ingot, yomwe imadziwika kuti ndi njerwa yothamanga. Amagwiritsidwa ntchito kwambiri kuti achepetse kukana kwachitsulo chosungunuka ndikuletsa kutayikira kwachitsulo. Makhalidwe akuluakulu amaphatikizapo kukana kutentha kwa kutentha, kukana kuvala, madzi abwino, kuyika kosavuta komanso kukana moto wabwino.
1. Gulu potengera zinthu:
(1) Dongo:Uwu ndiye mtundu wofunikira kwambiri wa njerwa zachitsulo zoyenda, zopangidwa ndi dongo wamba. Ngakhale mtengo wake ndi wotsika, ndi wocheperako pakukana moto komanso moyo wautumiki, ndipo ndi woyenera mphero zing'onozing'ono zachitsulo kapena zochitika zogwiritsa ntchito kwakanthawi.
(2) aluminiyamu yapamwamba:Njerwa yachitsulo yothamangayi imakhala ndi aluminiyamu yambiri, imakhala ndi mphamvu yabwino kwambiri yolimbana ndi moto, ndipo imatha kukhala yokhazikika m'malo otentha kwambiri. Nthawi zambiri amagwiritsidwa ntchito m'mabizinesi akuluakulu azitsulo, makamaka popanga zitsulo zomwe zimafunikira kupirira kutentha kwanthawi yayitali. pa
(3) Zambiri:Makhiristo ooneka ngati singano amakhala ndi mawonekedwe amtundu wa netiweki, omwe amatha kuteteza kukokoloka ndi chitsulo chosungunuka. Pakali pano ndi nkhani wamba.
2. Gulu mwa magwiridwe antchito:
(1) Njerwa zapakati
Amagwiritsidwa ntchito m'dera lapakati la chitsulo chosungunuka, chothandizira njira yothamanga komanso yofunikira kwambiri
refractoriness ndi kukokoloka kukana.
(2) Njerwa Zogawa Chitsulo
Amagwiritsidwa ntchito popatutsa chitsulo chosungunuka ku nkhungu zosiyanasiyana. Zodziwika bwino zimaphatikizapo mabowo awiri, atatu, ndi quadruple, malingana ndi zofunikira za ndondomeko.
(3) Njerwa za Mchira
Zomwe zili kumapeto kwa kayendedwe kazitsulo, zimapirira zitsulo zosungunuka ndi kutentha kwakukulu ndipo zimafuna kukana kusweka.

Kugwiritsa ntchito
Njerwa zachitsulo zoyendaamagwiritsidwa ntchito makamaka poponyera pansi, kukhala ngati njira yopangira zitsulo zosungunuka kuti ziyende kuchokera ku ladle kupita ku nkhungu za ingot, kuonetsetsa kuti zitsulo zosungunuka zigawidwe bwino pa nkhungu iliyonse ya ingot.
Ntchito Yoyambira
Njerwa zachitsulo zoyenda, kupyola mkati mwake mopanda kanthu, zimaonetsetsa kuti chitsulo chosungunula chikuyenda molunjika, kuti chisakhudze nkhungu za ingot ndikuchepetsa kulephera kwamapangidwe komwe kumachitika chifukwa cha kutenthedwa komweko. Komanso, katundu wawo refractory amalola kupirira kukhudza thupi ndi zochita za mankhwala a mkulu kutentha zitsulo zosungunuka, kuteteza zonyansa kulowa zitsulo ndi kukhudza khalidwe lake.
Mbiri Yakampani
Malingaliro a kampani Shandong Robert New Material Co., Ltd.ili mu Zibo City, Province Shandong, China, amene ndi refractory zinthu kupanga m'munsi. Ndife makampani amakono omwe amaphatikiza kafukufuku ndi chitukuko, kupanga, kugulitsa, kapangidwe ka ng'anjo ndi zomangamanga, ukadaulo, ndi zida zotumizira kunja. Tili ndi zida zonse, ukadaulo wapamwamba, mphamvu zolimba zaukadaulo, mtundu wabwino kwambiri wazinthu, komanso mbiri yabwino. Fakitale yathu imakhala ndi maekala opitilira 200 ndipo zotulutsa zowoneka bwino zowoneka bwino zimakhala pafupifupi matani 30000 ndipo zida zosapanga dzimbiri ndi matani 12000.
Zogulitsa zathu zazikulu za zida zokanira zikuphatikizapo: zinthu zamchere zotsutsa; zotayidwa silicon refractory zipangizo; zinthu zosapanganika zokanira; kutchinjiriza matenthedwe refractory zipangizo; zida zapadera zokanira; zinchito refractory zipangizo mosalekeza kuponya kachitidwe.
Mafunso Ofunsidwa Kawirikawiri
Mukufuna thandizo? Onetsetsani kuti mwayendera mabwalo athu othandizira kuti mupeze mayankho a mafunso anu!
Ndife opanga zenizeni, fakitale yathu ndi yapadera popanga zida zokanira kwa zaka zopitilira 30. Timalonjeza kupereka mtengo wabwino kwambiri, ntchito yabwino kwambiri yogulitsiratu komanso yogulitsa pambuyo pake.
Panjira iliyonse yopanga, RBT ili ndi dongosolo lathunthu la QC la kapangidwe kake ndi zinthu zakuthupi. Ndipo tidzayesa katunduyo, ndipo chiphaso chabwino chidzatumizidwa ndi katunduyo. Ngati muli ndi zofunikira zapadera, tidzayesetsa kuti tikwaniritse.
Malingana ndi kuchuluka kwake, nthawi yathu yoperekera ndi yosiyana. Koma tikulonjeza kutumiza mwamsanga ndi khalidwe lotsimikizika.
Inde, timapereka zitsanzo zaulere.
Inde, ndithudi, ndinu olandiridwa kukaona RBT kampani ndi katundu wathu.
Palibe malire, titha kukupatsani malingaliro ndi yankho labwino kwambiri malinga ndi momwe mulili.
Takhala tikupanga zida zodzitchinjiriza kwa zaka zopitilira 30, tili ndi chithandizo champhamvu chaukadaulo komanso luso lolemera, titha kuthandiza makasitomala kupanga ma kilns osiyanasiyana ndikupereka ntchito imodzi.
