Zigawo zikuluzikulu za zipangizo refractory monga njerwa zopumira, njerwa zomangira mphuno, ndi zomangira

Zipangizo Refractory chimagwiritsidwa ntchito zitsulo, luso mankhwala, mafuta ndi petrochemical, makina kupanga, processing mphamvu ndi minda ina mafakitale, amene ndalama yaikulu ntchito mu makampani zitsulo. Muzitsulo zazitsulo ndi ng’anjo zoyenga mumakampani opanga zitsulo, zipangizo zokanira zomwe zimagwiritsidwa ntchito ndi opanga zitsulo zimaphatikizapo njerwa zopuma, njerwa za nozzle block, zovundikira ng’anjo yamagetsi, zotayira, mchenga wamtsinje, njerwa za carbon magnesia, ndi zina zotero. zigawo zikuluzikulu ndi zowonjezera zowonjezera ndizosiyana kwambiri. Kuchokera kusanthula kwamankhwala, zida zotsutsa zimapangidwa ndi mchere, monga corundum, mullite, magnesia, ndi zina. Zigawo zazikuluzikulu zomwe ndi alumina ndi magnesia.

Ponena za chigawo chachikulu cha zinthu refractory, ndi masanjidwewo chigawo kuti amapanga katundu wa refractory, ndiye maziko a makhalidwe a zipangizo refractory, ndi mwachindunji amatsimikiza katundu wa mankhwala refractory. Mwachitsanzo, njerwa zopuma mpweya zimafunika kupangidwa ndi miyala yamtengo wapatali, ndiyeno zimapangidwira njira zokhwima komanso zomveka, kuti zitsimikizire kuti moyo wa njerwa zopumira zomwe zimagwiritsidwa ntchito ndi opanga zitsulo zimatha kukwaniritsa zofunikira. Zigawo zikuluzikulu za zipangizo refractory akhoza oxides (aluminium okusayidi, magnesium okusayidi, etc.), kapena zinthu kapena sanali okusayidi mankhwala (carbon, pakachitsulo carbide, etc.).

Malinga ndi chikhalidwe cha zigawo zikuluzikulu, zipangizo refractory akhoza kugawidwa m’magulu atatu: acidic, ndale, ndi zamchere. Acidic refractory zipangizo makamaka zipangizo okhala acidic oxides monga silicon okusayidi. Chigawo chachikulu ndi silicic acid kapena aluminium silicate, yomwe imapanga mchere pansi pa kutentha kwakukulu ndi zamchere. Waukulu mankhwala zigawo zikuluzikulu zamchere refractories ndi magnesium okusayidi, calcium okusayidi, etc. Common refractory mankhwala monga ngalande mchenga ndi ladle slide. Refractories osalowerera ndale ndi carbonaceous ndi chromium refractories. Kuphatikiza apo, ma refractories a aluminiyamu apamwamba (zomwe zili ndi aluminiyamu kuposa 45%) ndizosalowerera ndale zomwe zimakonda kukhala acidic, pomwe ma chromium refractories amakhala amchere kwambiri. Pazinthu zosalowerera ndale, zida zodziwikiratu za aluminiyamu zapamwamba zimaphatikizira njerwa zopumira, njerwa zotsekera, ndi zovundikira ng’anjo yamagetsi.

Kampani yathu ili ndi zaka 18 za kafukufuku ndi chitukuko, kupanga ndi kugulitsa zinthu zotsutsa monga njerwa zopumira, njerwa za nozzle block, castables, ndi mapepala ovomerezeka, mapangidwe apadera, ndi kukhazikitsa kokhazikika ndi kovomerezeka kwa ndondomeko iliyonse, kuti opanga zitsulo azigwiritsa ntchito. ndi mtendere wamumtima ndi chitonthozo.
