Mukufuna njira zodalirika zopewera kutentha kwambiri m'mafakitale?SK34 firebricksNdi chisankho chodalirika cha zitsulo, kupanga magalasi, zoumbaumba, ndi zina zotero. Zopangidwa ndi mankhwala enieni komanso kutentha kwapamwamba, njerwa izi zimapereka kulimba kwapadera komanso magwiridwe antchito, kukhala maziko a uvuni ndi ng'anjo zogwira ntchito bwino padziko lonse lapansi.
1. Makhalidwe Aakulu a SK34 Firebricks
Ma firebricks a SK34 amadziwika bwino chifukwa cha kukhazikika kwawo bwino pa kutentha, mphamvu ya makina, komanso kukana dzimbiri, zomwe zimachokera ku kupanga kwapamwamba komanso kusakaniza zinthu zoyeretsedwa bwino. Zinthu zazikulu ndi izi:
- Kulekerera Kwambiri Kutentha Kwambiri:Pokhala ndi SK34 (kukana kwa 1710–1750°C) yokhala ndi kukana kwa 1350°C pansi pa katundu (RUL) pa 0.2 MPa, amagwira ntchito modalirika pa kutentha kwapakati mpaka kwakukulu popanda kufewetsa kapena kusintha, zomwe ndizofunikira kwambiri pakukonzekera kutentha nthawi zonse.
- Zodzoladzola Zamankhwala Zokonzedwa Bwino:Pokhala ndi alumina 34–42% (Al₂O₃) ndi <2.5% ferric oxide (Fe₂O₃), amalimbana ndi kukokoloka kwa asidi ndipo amachepetsa kuwonongeka kokhudzana ndi utsi, zomwe zimawonjezera nthawi yogwira ntchito m'mafakitale ovuta.
- Kapangidwe Kolimba & Kokhuthala:Ndi kuchuluka kwa 2.15–2.20 g/cm³ komanso mphamvu yozizira yophwanyira ≥30 MPa, zimapirira kusweka ndi kugwedezeka. Kuchepa kwa ma porosity (19–23%) kumachepetsa kutayika kwa kutentha ndipo kumaletsa kulowa kwa zinthu zosungunuka, kusunga mawonekedwe ake.
- Kukhazikika Kwambiri kwa Kutentha kwa Kutentha:Pokhala ndi kukula kwa mzere kwa 0.6% pa 1000°C ndi ±0.3% kusintha kwa mzere kosatha pa 1350°C (maola awiri), zimapirira kusinthasintha kwa kutentha mwachangu popanda kusweka kapena kuphulika, kuchepetsa kukonza ndi nthawi yopuma.
- Kukula Kosinthasintha:Zimapezeka mu kukula koyenera (230×115×25 mm, 230×115×75 mm) ndi mawonekedwe apadera (arch, corbel bricks), zimagwirizana ndi zida zotenthetsera zokhazikika komanso zapadera, zomwe zimapangitsa kuti zikhale zosavuta kugwiritsa ntchito.
2. Ntchito Zofunika Kwambiri Zamakampani
Kugwira ntchito bwino kwa SK34 firebricks kumawapangitsa kukhala ofunikira kwambiri m'magawo ofunikira:
Zachitsulo:Pogwiritsa ntchito ziwiya zamagetsi zozungulira, ziwiya zoyatsira magetsi, ziwiya zoyatsira magetsi, ndi ziwiya zoyatsira magetsi popanga zitsulo/chitsulo, zimalimbana ndi kukokoloka kwa chitsulo chosungunuka ndi slag, zomwe zimapangitsa kuti njira zosungunulira zitsulo zikhale zokhazikika.
Galasi ndi Zoumbaumba:Zabwino kwambiri pa uvuni wosungunuka magalasi ndi ma uvuni a ceramic, kukana kutentha kwambiri komanso kukhazikika kwa kutentha kumasunga kutentha kofanana, kofunikira kwambiri pakupanga magalasi ndi kuwotcha kwa ceramic.
Mphamvu ya Mankhwala ndi Kutentha:Amagwiritsidwa ntchito m'zipinda zamakina opangira mankhwala, zotenthetsera zinyalala, ndi zipinda zoyatsira moto za boiler, amapirira mpweya wowononga komanso kutentha kwambiri, zomwe zimapangitsa kuti ntchito ikhale yotetezeka komanso yogwira mtima.
Magawo Ena:Imagwiritsidwanso ntchito m'ma cupolas a foundry, ma uvuni a njerwa, ndi makina otenthetsera mafakitale, zomwe zimagwirizana ndi zosowa zosiyanasiyana zamafakitale zomwe zimafuna kutentha kwambiri.
Sankhani zitini za moto za SK34 kuti zigwire bwino ntchito pa kutentha kwambiri. Zogulitsa zathu zikukwaniritsa miyezo yapamwamba yapadziko lonse, yokhala ndi mayankho osinthika kuti agwirizane ndi zosowa zanu. Lumikizanani nafe lero kuti mudziwe momwe zitini za moto za SK34 zingathandizire magwiridwe antchito a zida zanu komanso kukhala ndi moyo wautali.
