Ubwino njerwa zaumbali mu kumanga chitetezo moto

Njerwa zomangira zimatchedwa njerwa yamoto. Refractory yopangidwa ndi dongo losagwira moto kapena zinthu zina zokana. Wotumbululuka wachikasu kapena wofiirira. Amagwiritsidwa ntchito kwambiri pomanga ng’anjo zosungunulira, amatha kupirira kutentha kwa 1,580 ℃-1,770 ℃. Amatchedwanso firebrick. Refractory zinthu ndi mawonekedwe ndi kukula.

Njerwa zokanira zimagwiritsidwa ntchito kwambiri mumakampani okana. Chifukwa cha kukana kwawo kwakukulu, amakhala omasuka kwambiri poteteza moto. Njerwa zomangira zimadalira kwambiri aluminium oxide refractory. The apamwamba zili, ndi apamwamba refractory kutentha. Njerwa zomangira Kulimba kwake ndikwamphamvu kuposa njerwa zofiira wamba, ndipo ndikwabwinoko pakugwiritsira ntchito pomanga chitetezo chamoto.

Refractory njerwa mapu enieni

M’zomangamanga zambiri, chitetezo cha moto cha nyumba chimaperekedwa patsogolo, makamaka zomwe zili ndi kutalika kwa pansi kuposa 20 pansi. Zofunikira pazida zoteteza moto ndizovuta kwambiri. Gwiritsani ntchito firewall kudzipatula. Njerwa zokanira ndi zina mwazinthu zambiri zokanira. Mu zomangamanga zozimitsa moto, njerwa zamtundu wa dziko zimagwiritsidwa ntchito kwambiri. Kukula ndi 230mmx114mmx65mm, chitsanzo ndi T-3, ndi kulemera kwake ndi 3.5-3.7kg. Nthawi zina amagwiritsidwanso ntchito. Itha kugwiritsidwa ntchito ngati chowonjezera ku njerwa zomangira.

Njerwa zomangira nthawi zambiri zimapangidwa ndi dothi losasunthika pomanga. Refractory nthaka ali wamphamvu adhesion ndi refractoriness. Choncho, nthaka refractory chimagwiritsidwa ntchito refractory zomangamanga. Ngati pakufunika kukana moto pakumanga chitetezo chamoto, gwiritsani ntchito zomangamanga za simenti ya Refractory, refractoriness ya simenti ya refractory ndi pafupifupi 500 madigiri apamwamba kuposa dothi losakanizika.

Refractories nthawi zambiri amagawidwa m’magulu awiri, omwe ndi osawoneka bwino komanso opangira mawonekedwe. Ma refractories osaoneka bwino amatchedwanso castables, omwe ndi tinthu tating’onoting’ono ta ufa wopangidwa ndi mitundu yosiyanasiyana yamagulu kapena ma aggregates ndi zomangira chimodzi kapena zingapo. Ayenera kusakaniza ndi madzi amodzi kapena angapo ndikusakaniza mofanana akagwiritsidwa ntchito. Wamphamvu liquidity. Zipangizo zomangira zooneka ngati njerwa zimatanthawuza njerwa zosasunthika, zomwe mawonekedwe ake ali ndi malamulo okhazikika, ndipo zimatha kukonzedwanso kwakanthawi ngati pakufunika pomanga ndi kudula.
