Kodi maubwino apakatikati pazitsulo zamoto zopangira zida zopangira ndi chiyani?

Ramming zakuthupi zimatanthawuza zinthu zosasunthika zomwe zimapangidwa ndi ramming (pamanja kapena pamakina) ndipo zimaumitsidwa pakatenthedwe pamwambapa kutentha. Zimapangidwa ndi kusakaniza magulu ophatikizira, ufa, zomangiriza, zokometsera, madzi kapena zakumwa zina ndimiyeso ina. Malinga ndi mtundu wazida zopangira, pali alumina apamwamba, dongo, magnesia, dolomite, zirconium ndi silicon carbide-carbon refractory ramming.

Zida zosagwira moto zofananira zimafaniziridwa ndi zida zina zamtundu. Zipangizo zouluka ndi zowuma kapena zowuma komanso zotayirira. Ambiri aiwo alibe zomatira asanapange. Chifukwa chake, kulumikizana mwamphamvu kokha ndi komwe kumatha kupeza mawonekedwe wandiweyani. Poyerekeza ndi zotumphukira ndi pulasitiki, zida zogwiritsa ntchito rammam zimakhala zolimba kwambiri komanso zimatha kutentha pamatentha. Komabe, zimadaliranso kusankha kwa zipangizo zamtengo wapatali, ndipo chiŵerengero choyenera cha pellets ndi ufa zimagwirizananso kwambiri.

Zinthu zopangira ramming ndi zotheka zonse ndizopangira, koma palinso kusiyana pakati pa ziwirizi:

1. Kusiyana kwa kapangidwe kazinthu zopangidwazo: Zinthu zomwe zimapangidwanso ndizopangika zopangidwa mosiyanasiyana zopangidwa ndi tinthu tating’onoting’ono ta ufa ndi chophatikizira chophatikizira ndi zowonjezera, zomwe zimamangidwa ndi ramming yamanja kapena yamakina.

2. Zida zopangira ma ramming zimaphatikizapo zida zopangira ma corundum, zida zapamwamba zopangira alumina, zida za silicon carbide, zida zopangira kaboni, zida za silicon, zida za magnesium, ndi zina zambiri. monga zopangira, zosakanikirana ndi zowonjezera zowonjezera za ufa wabwino kwambiri, simenti yosakanikirana kapena utomoni wambiri monga chomangira chopangidwa ndi zinthu zambiri. Amagwiritsidwa ntchito kudzaza kusiyana pakati pa zida zoziziritsira m’ng’anjo ndi zomangamanga kapena zodzaza ndi masanjidwe osanja.

1. Chosunthika ndi mtundu wa zinthu zopangidwa ndi granular ndi powdery zopangidwa ndi zida zotsutsa komanso kuchuluka kwa binder. Ndi fluidity mkulu, ndi oyenera unshaped zipangizo refractory anapanga ndi kuponyera njira. Zida zitatu zazikuluzikulu zotayika ndizofunikira kwambiri, zowonjezera komanso zosadetsedwa, zomwe zidagawika: gulu, ufa ndi binder. Zopangira zophatikiza zimaphatikizapo silika, diabase, andesite ndi waxstone.
