Ntchito yayikulu ya njerwa zotsekera ndikusunga kutentha ndikuchepetsa kutaya kutentha. Njerwa zotsekereza sizimalumikizana mwachindunji ndi lawi lamoto, ndipo njerwa zamoto nthawi zambiri zimalumikizana ndi lawi. Njerwa zamoto zimagwiritsidwa ntchito makamaka kupirira lawi lamoto wowotcha. Nthawi zambiri imagawika m'mitundu iwiri, yomwe ndi yosawerengeka Yosaoneka bwino komanso yowoneka ngati yokanira.
Zosawoneka Zosasinthika
The castables refractory zakuthupi ndi wosakaniza powdery tinthu wopangidwa ndi zosiyanasiyana aggregates kapena aggregates ndi mmodzi kapena kuposa binders. Kugwiritsa ntchito kuyenera kusakanizidwa ndi chakumwa chimodzi kapena zingapo, ndi madzi amphamvu.
Zowoneka Zowonekera
M'mikhalidwe yabwino, mawonekedwe a njerwa zotsutsa amakhala ndi kukula kwake, amathanso kusinthidwa malinga ndi zofuna za makasitomala.
Kusiyanitsa Kwakukulu Pakati pa Njerwa Zoyimitsa Zomangamanga & Zamoto
1. Insulation Performance
The matenthedwe madutsidwe njerwa kutchinjiriza zambiri 0.2-0.4 (avereji kutentha 350±25°C) w/mk, ndi matenthedwe madutsidwe wa njerwa firebrick ndi pamwamba 1.0 (avereji kutentha 350±25°C)w/mk Choncho, kutchinjiriza matenthedwe. Kugwira ntchito kwa njerwa zotsekereza ndikwabwino kuposa njerwa zamoto.
2. Kukana
The refractoriness wa njerwa insulatory zambiri pansi madigiri 1400, ndipo refractoriness wa njerwa refractory ndi pamwamba 1400 madigiri.
3. Kuchulukana
Njerwa zotsekereza ndi zida zotchinjiriza zopepuka, kachulukidwe ka njerwa zotsekera nthawi zambiri ndi 0.8-1.0g/cm3 ndipo kachulukidwe ka njerwa zomangira zimakhala pamwamba pa 2.0g/cm3.
Mapeto
Mwachidule, njerwa yotsutsa imakhala ndi mphamvu zambiri zamakina, moyo wautali wautumiki, kukhazikika kwamankhwala abwino, kusagwirizana ndi mankhwala ndi zinthu komanso kukana kwabwino kwa kutentha, komanso kutentha kwambiri kosatha kutentha kumatha kufika 1900 ° C. Njerwa za refractory ndizoyenera kugwiritsidwa ntchito pazosintha zotsika kwambiri za kutentha, osintha, otembenuza ma hydrogenation, akasinja a desulfurization, ndi ng'anjo za methanation zamafuta a feteleza amafuta kuti azigwira ntchito yomwaza zakumwa za gasi, kuthandizira, kuphimba, ndi kuteteza zoyambitsa. Njerwa zozimitsa moto zitha kugwiritsidwanso ntchito mu masitovu otentha ndi zida zosinthira zotenthetsera m'makampani azitsulo.
Njerwa zamoto zimakhala ndi ubwino wochuluka kwambiri, mphamvu zambiri, kukana kuvala, kukana bwino kwa dzimbiri, kutsika kwa kutentha kwapakati, kutentha kwakukulu, phokoso lochepa, moyo wautali wautumiki, ndi zipangizo zosaipitsa. Ndi njira yabwino yopera yomwe ili yoyenera makina osiyanasiyana opera.
Njerwa zokanira ndi njerwa zosungunulira ndizosiyana kwambiri, kugwiritsa ntchito kwawo chilengedwe, kukula kwake ndi ntchito sizili zofanana. Zida zosiyanasiyana zidzagwiritsidwa ntchito m'malo osiyanasiyana. Pogula zinthu, tiyenera kusankha mtundu wa zinthu zokanira zomwe zili zoyenera kuti tigwiritse ntchito molingana ndi momwe tilili.
