Sebenzisa iimeko zezitena eziphikisayo kwiziko
Imiqathango yokusetyenziswa kwe izitena ezenza izitena kwiziko
Kwiimeko eziqhelekileyo, injongo ephambili yezitena eziphikisayo kwi-kiln lining kukuphucula ukusebenza kakuhle kwe-lining, kunokulibazisa ukuveliswa ngenxa yomonakalo wezitena eziphikisayo ngexesha lokucubungula. Ngoko ke, izitena eziphikisayo zesithando somlilo kufuneka zikhethwe ngokuhambelana nobomi kunye nokusebenza kakuhle kwesithando somlilo. Isitena esichasayo sisixhobo se-inorganic non-metallic esinomda wokumelana nomlilo ongaphezulu kwe-1580°C. Ukushisa okuphezulu kunye nokungazinzi komthwalo wezitena eziphikisayo, oko kukuthi, iimpawu zokunganyibiliki kunye nokuthambisa phantsi kweqondo lokushisa eliphezulu kunye nemigangatho yokungabikho komthwalo, kuthiwa yi-refractoriness, ebonisa iimpawu ezisisiseko zezitena eziphikisayo.
Izitena ezichasayo, njengezona zinto ziphambili kwiifurnas eziphezulu zokushisa kunye nezinye izibonelelo ze-thermal, ziyakwazi ukumelana nemiphumo eyahlukeneyo yomzimba kunye noomatshini. Ke ngoko, le migangatho ilandelayo kufuneka ifezekiswe:
(1) Ukuze kuhlangatyezwane neemfuno zokusetyenziswa kobushushu obuphezulu, kufuneka kube neempawu zokungathambi kwaye zinganyibiliki kwiqondo lokushisa eliphezulu ngokwaneleyo.
(2) Iyakwazi ukumelana nomthwalo wesithando somlilo kunye noxinzelelo oluhlala lusebenza ngexesha lokusebenza, alukho amandla olwakhiwo, kwaye aluthambi, lukhubaze kwaye luwa kumaqondo aphezulu. Ibonakaliswa ngokubanzi ngobushushu bokuthambisa umthwalo.
(3) Kwiqondo lokushisa eliphezulu, umthamo uzinzile, kwaye umzimba we-oven okanye umzimba wokuthulula awuyi kudilika ngenxa yokwandiswa okugqithisileyo kwemveliso, okanye ukuqhekeka ngenxa yokunciphisa kakhulu, ngaloo ndlela ukunciphisa ubomi benkonzo. Ngokuqhelekileyo qwalasela i-coefficient yokwandiswa kwe-thermal kunye ne-reheating shrinkage (okanye ukwandiswa).
(4) Izitena eziphikisayo zichaphazeleka kakhulu ngeemeko zesithando somlilo. Ngenxa yokutshintsha kakuhle kweqondo lokushisa kunye nokufudumala okungalinganiyo, umzimba wesithando somlilo uwonakaliswa lula. Ke ngoko, kuyafuneka ukuba ube nenqanaba elithile lokuxhathisa ukothuka kwe-thermal.
(5) Ngethuba lokusetyenziswa, izitena eziphikisayo zihlala zixutywe ngesisombululo se-liquid, i-gaseous okanye i-solid organic matter, ebangela ukuba imveliso ibe ne-corrod kwaye yonakaliswe. Ngoko ke, imveliso iyadingeka ukuba ibe neqondo elithile lokumelana nokubola.
(6) Kwinkqubo yokufakwa kwesicelo, izitena eziphikisayo zihlala zigqweswa ngamadangatye ahamba ngesantya esiphezulu kunye nothuli, i-corrosion ye-corrosion yentsimbi engamanzi kunye ne-slag etyhidiweyo, kunye nomonakalo wokungqubana phakathi kwesinyithi kunye nezinye izinto eziluhlaza. Ngoko ke, kuyafuneka ukuba ube namandla okwaneleyo kunye nokuxhathisa ukubola.
