Njerwa Zosasinthika za Magnesia
Njerwa zopinga za MagnesiaNdi zinthu zotsutsana ndi alkaline zomwe zimakhala ndi magnesium oxide (MgO) yoyera kwambiri (nthawi zambiri ≥85%) ndi periclase (MgO) ngati gawo loyambirira la kristalo. Zimapereka zabwino zazikulu monga kukana kwambiri komanso kukana kwambiri kukokoloka kwa slag ya alkaline, ndipo zimagwiritsidwa ntchito kwambiri m'mafakitale otentha kwambiri monga zitsulo ndi zipangizo zomangira. Cholepheretsa chawo chachikulu ndi kukana kutentha kwambiri.
Gulu:
Njerwa za Magnesia Zopangidwa ndi Sintered:
Kuchuluka kwa MgO kumayambira pa 91% mpaka 96.5%. Magiredi wamba amatchedwa 92 Magnesia Brick, 95 Magnesia Brick, ndi 97 Magnesia Brick.
Magiredi omwe amagwiritsidwa ntchito kwambiri (ma marks): MG, MZ.
Njerwa za Magnesia Zosakanikirana:
Kuchuluka kwa MgO kumayambira pa 95.5% mpaka 98.2%. Magulu ofanana amatchedwa Fused 95 Magnesia Brick, Fused 97 Magnesia Brick, ndi Fused 98 Magnesia Brick.
Magiredi omwe amagwiritsidwa ntchito kwambiri (ma marks): DM, MZ.
Kusakhazikika—Njerwa za magnesium zimakhala ndi mphamvu yolimba kwambiri, nthawi zambiri zimapitirira 2000°C.
Kutentha kofewetsa katundu—Kutentha koyambira kwa njerwa za magnesia komwe kumafewetsa katundu kumakhala kotsika kwambiri poyerekeza ndi kukana kwawo, pafupifupi 1530 ~ 1580°C.
Njerwa za magnesium zimakhala ndi mphamvu yabwino yotenthetsera kutentha—Njerwa za magnesium zimakhala ndi mphamvu yoyendetsera kutentha kowirikiza kangapo kuposa njerwa zadothi, ndipo mphamvu yawo yoyendetsera kutentha imachepa kutentha kukakwera.
Njerwa za magnesium sizimakhudzidwa ndi kutentha kwambiri—Zimatha kupirira kuzizira kwa madzi kwa mphindi ziwiri kapena zitatu zokha. Izi zimachitika chifukwa cha kuchuluka kwa kutentha komwe kumawonjezeka komanso kutentha kotsika, zomwe zimapangitsa kuti zikhale ndi vuto lalikulu la kutentha pakasintha kutentha mwachangu.
Kukana matope ndi kukana madzi—Njerwa za magnesium sizimalimbana ndi alkali koma sizimalimbana ndi asidi. Kupangidwa kwa magnesium ferrite ndi calcium magnesium olivine kumachepetsa kukana kwawo madzi. Chifukwa chake, kuletsa madzi kulowa m'madzi ndi kuteteza chinyezi ndikofunikira nthawi zonse.

Makampani Opanga Zitsulo ndi Zitsulo:
Amagwiritsidwa ntchito mu BOFs (Basic Oxygen Furnaces), EAFs (Electric Arc Furnaces), ndi ma ladle linings, komanso ma mixer ndi ferroalloy furnaces. Amalimbana ndi kukokoloka kwa nthaka kuchokera ku zitsulo zosungunuka ndi alkaline slags.
Makampani Opanga Zipangizo Zomangira:
Amagwiritsidwa ntchito m'malo oyaka moto ndi malo osinthira a ma uvuni ozungulira a simenti, komanso ngati zophimba ma uvuni a lime. Amapirira dzimbiri la alkali kuchokera ku clinker ndi scouring yotentha kwambiri.
Zitsulo zopanda chitsulo:
Amagwiritsidwa ntchito ngati zophimba ng'anjo zosungunulira ndi zotsukira ng'anjo zopangira mkuwa, nikeli, ndi zina zotero. Ndi yoyenera kutentha kwambiri komanso dzimbiri lochokera ku zitsulo zosungunuka zopanda chitsulo.
Ntchito Zina:
Amagwiritsidwa ntchito ngati zotchingira zida zotenthetsera kwambiri monga zobwezeretsanso ng'anjo yagalasi, zotenthetsera mankhwala zotenthetsera kwambiri, ndi zotenthetsera zinyalala.
Mafunso Ofunsidwa Kawirikawiri
Mukufuna thandizo? Onetsetsani kuti mwapita ku malo athu othandizira kuti mupeze mayankho a mafunso anu!
Ndife opanga enieni, fakitale yathu yakhala ikupanga zinthu zotsutsa kwa zaka zoposa 30. Tikulonjeza kupereka mtengo wabwino kwambiri, ntchito yabwino kwambiri yogulitsa zinthu zisanagulitsidwe komanso zitagulitsidwa.
Pa njira iliyonse yopangira, RBT ili ndi dongosolo lathunthu la QC la kapangidwe ka mankhwala ndi mawonekedwe ake. Ndipo tidzayesa katunduyo, ndipo satifiketi yaubwino idzatumizidwa ndi katunduyo. Ngati muli ndi zofunikira zapadera, tidzayesetsa momwe tingathere kuti zigwirizane nazo.
Kutengera kuchuluka kwa katundu, nthawi yathu yotumizira ndi yosiyana. Koma tikulonjeza kutumiza mwachangu momwe tingathere ndi mtundu wotsimikizika.
Inde, timapereka zitsanzo zaulere.
Inde, ndithudi, mwalandiridwa kupita ku kampani ya RBT ndi zinthu zathu.
Palibe malire, titha kupereka malingaliro abwino kwambiri komanso yankho malinga ndi momwe zinthu zilili.
Takhala tikupanga zinthu zopinga kwa zaka zoposa 30, tili ndi chithandizo champhamvu chaukadaulo komanso chidziwitso chambiri, titha kuthandiza makasitomala kupanga ma uvuni osiyanasiyana ndikupereka chithandizo chimodzi chokha.
