Ukomisa, ukufudumeza kunye nokugcinwa kwezinto ezifakwe kwi-sement kiln castables

I-castable eqinisiweyo okanye eyomisiweyo isenamanzi ashiyekileyo asemzimbeni kunye neekhemikhali, kwaye emva koko ifudunyezwe ukuya kuma-300 ℃ ukuze ibe ngumphunga kwaye ikhuphe amanzi, kwaye onke amanzi ayakukhutshwa. Ngenxa yokuba i-castable inesakhiwo esixineneyo, izinga lokufudumeza kufuneka licothe ukunqanda ukunyuka kobushushu ngokukhawuleza. Uxinzelelo olubangelwa ukuphuphuma ngokukhawuleza okuphezulu kunye nomswakama kubangela umonakalo we-castable.

Inkqubo yokomisa kunye nokufudumeza kwenkqubo ye-kiln ngamanye amaxesha ayinakuhlangabezana neemfuno zokomisa kwi-preheater kunye ne-calciner (i-grate epholileyo, i-kiln hood kunye ne-tertiary air duct idibana nenkqubo yokomisa kunye nokufudumeza kwenkqubo ye-kiln, kwaye ayidweliswanga ngokwahlukileyo), ngoko ke, Inkqubo yokufudumala yokubhaka ye-oven system ekhankanywe ngezantsi kufuneka idibaniswe neemfuno zeli candelo. Ukuba ubushushu benkqubo ye-oven bufikelela kuma-600 ° C (ngokuxhomekeke kwiqondo lobushushu legesi yokukhupha kumsila), i-preheater yokuqala ayihlangabezani neemfuno zokomisa, kunye nexesha lokugcinwa kobushushu kwi-600 ° C kufuneka. kwandiswe.

Ixesha lokunyanga lebhetshi yokugqibela yee-refractory castables alikho ngaphantsi kwe-24h kwiqondo lokushisa malunga ne-25 ° C (kwii-castable ze-samente eziphantsi, ixesha lokunyanga kufuneka landiswe kwi-48h ngokufanelekileyo). Emva kokuba i-castable ifumene amandla athile, susa i-formwork kunye nenkxaso. Ukubhaka kunokwenziwa emva kokumisa kwe-24h. Ukuba iqondo lokushisa liphantsi kakhulu, ixesha lokunyanga kufuneka landiswe.

Thatha ubushushu begesi yokukhupha kwi-kiln tail njengomgangatho, kwaye usebenzise izinga lokushisa kwe-15 ° C / h de lifike kwi-200 ° C, kwaye ligcine iiyure ezili-12.

Phakamisa iqondo lokushisa ukuya kwi-400 ° C kwiqondo lokushisa elingu-25 ° C / h, kwaye ugcine ubushushu obungaphantsi kwe-6h.

Phakamisa ubushushu ukuya kwi-600 ° C kwaye ugcine ubushushu bungekho ngaphantsi kwe-6h. Le miqathango mibini ilandelayo ziimeko eziyimfuneko nezaneleyo zokubhaka i-calciner kunye ne-preheater system:

Xa iqondo lobushushu le-refractory castable kumngxunya othululwayo we-cyclone preheater kufutshane nesigqubuthelo se-silicon sifikelela kwi-100℃, ixesha lokumisa aliyi kuba ngaphantsi kwe-24h.

Kumnyango womngxuma womgangatho wokuqala we-cyclone preheater, isiqwenga seglasi esicocekileyo sasetyenziselwa ukunxibelelana nerhasi ye-flue, kwaye akukho kuvuza komswakama kwiglasi. Ixesha lokugcinwa kobushushu yayiziyure ezi-6.
