Ulwahlulo lwe izinto eziphikisayo yesamente ejikelezayo kwiziko

1. Umlomo we-kiln 0.6m wenziwe nge-corundum-resistant castable;

Isibane esingaphambili sekontini yesamente lelinye lamakhonkco abuthathaka kwiitoni ezininzi ezijikelezayo. Kwinkqubo yokuvelisa i-rotary kiln, umjikelo wokusebenza we-kiln lining ukhawulela ngokungqongqo ubomi benkonzo ye-kiln yonke. Ukongeza, ukwakhiwa kweqhosha le-kiln kunye ne-kiln lining nayo inzima kakhulu. Ulwakhiwo lwe-casting ngokubanzi lusebenzisa i-corundum-resistant castable. I-Corundum ekwazi ukumelana nokunxiba ayinayo kuphela ukuxhathisa okuqinileyo kunye nokumelana nomlilo ophezulu, kodwa inokumelana kakuhle neekhemikhali kunye nokuxhathisa ukothuka kwe-thermal. Okubaluleke ngakumbi, kulula ukwakha ngee-castables eziphikisayo. Iimeko ezinjalo zinokwenza ubomi benkonzo yebhoyila lula ukwandisa. Uphando lubonisa ukuba iinxalenye zesakhiwo ezisebenzisa i-corundum i-wear-resistant castable ine-avareji yobomi benkonzo engaphezulu kweenyanga ze-8.

Indawo yokupholisa yemitha eyi-1,

Ummandla wokwahlula kweemitha ezi-5 usebenzisa izitena ze-silicon mullite;

I-21.4-meter preheating zone ithatha izitena eziphezulu ze-aluminium ezichasayo;

Indawo yokudubula yeemitha ezingama-25 ithatha isitena se-magnesia chrome;

Ummandla wenguqu weemitha ezingama-20 wamkela izitena ze-spinel; indawo yokupholisa kunye nendawo yotshintsho ye-0.8m yecandelo leeko lesamente entsha yenkqubo eyomileyo ingakhetha izitena ze-silicon mullite okanye izitena ze-HMS ezingagugiyo.

2. I-1m yentsimbi ye-fiber enganyangekiyo enokugalelwa emlonyeni we-oven

Xa kuthelekiswa neziko elijikelezayo langaphambili, iqondo lobushushu lomsila omncinci lingaphantsi kwe-1000 ° C, kwaye linokufikelela malunga ne-700 ° C; iqondo lokushisa lomsila omkhulu we-kiln liphezulu njenge-1100 ° C, kwaye i-kiln tail ngokubanzi ayinayo i-skinning phenomenon. Kwiikhilni ezinomxholo ophezulu we-alkali okanye inani elincinci lamalahle aphezulu esulfure kwisidlo esikrwada, izinto ezinje ngealkali, isulfure, kunye neklorini zikhutshwa ngumphunga ngokuphindaphindiweyo kwaye ziqokelelwe, nto leyo ebangela ukuba amacandelo enze iiminerali ezinophawu lwe-crust, ngaloo ndlela zenza i-crusts i-kiln material , Enempembelelo enkulu kwimveliso kunye nokusebenza phantsi kwebhoyila. Ngemizamo yethu eqhubekayo, kwiminyaka yakutshanje, ukusetyenziswa kwe-fiber fiber-resistant-resistant castables okanye i-aluminiyam ephezulu yokunxiba i-castables kwi-rotary kilns iya kuphuculwa kakuhle.
