Yintoni isitena sokufakelwa kwe-thermal esikhaphukhaphu kwaye yintoni ukusetyenziswa kwayo?
Iyintoni isitena esilula sokufakelwa kwe-thermal kwaye yintoni na ukusetyenziswa kwayo?
Yintoni isitena esikhaphukhaphu sokugquma i-thermal? Njengoko igama libonisa, izitena ezilula ngokwentelekiso ezinomsebenzi wokugquma ubushushu zisetyenziselwa kakhulu ukugcinwa kobushushu kunye nokugquma ubushushu, ukonga amandla kunye nokunciphisa inkunkuma yamandla obushushu.
1. Izitena zodongwe ezilula
Le mveliso yimveliso ye-refractory lightweight, enomxholo we-AL2O3 we-30% -46%, isitena esinqandayo sokugcina ukushisa. Izinto eziphambili zezinto eziluhlaza ziyi-clinker yodongwe okanye i-clinker yodongwe olula kunye nodongwe lweplastiki oluveliswa ngendlela enokutsha. Izinto eziluhlaza zixutywe namanzi ukwenza udaka lweplastiki okanye udaka, olukhutshiweyo okanye luphoswe kwaye lomiswe kwindawo ene-oxidizing kwi-1250 ° C-1350 ° C.
2. Izitena ezikhaphukhaphu eziphezulu ze-alumina
Ikwaziwa ngokuba sisitena sokufakelwa kwe-alumina ephezulu ye-thermal, yinto ekhanyelayo ekhanyelayo kunye nomxholo we-alumina ongaphezulu kwe-48%, ikakhulu yenziwe yi-mullite kunye neglasi okanye i-corundum. Ubuninzi bobuninzi buyi-0.4 ~ 1.359 / cm3. I-porosity yi-66% ~ 73%, kwaye amandla oxinzelelo yi-1 ~ 8MPa. Ukumelana kakuhle nokothuka kwe-thermal;
Izitena ezikhaphukhaphu eziphezulu ze-alumina ngokubanzi zisebenzisa i-bauxite clinker ephezulu ye-alumina, yongeza udongwe oluncinci, kwaye emva koko usebenzise indlela yomoya okanye indlela ye-foam ukuphosa ngendlela ye-slurry emva kokuba iphantsi, kwaye emva koko umlilo kwi-1300 ~ 1500 ℃. I-alumina ye-industrial ngamanye amaxesha ingasetyenziselwa ukutshintsha inxalenye ye-bauxite clinker.
Ifanelekile kwi-internal lining kunye nobushushu bokufakelwa kobushushu be-oven, kunye neendawo ezingagqwaliswanga kwaye zihlanjululwe ngezinto ezinamandla ezinobushushu obuphezulu obutyhidiweyo. Xa udibana ngqo nedangatye, iqondo lobushushu bomphezulu akufunekanga lidlule kwi-1350°C.
3. Izitena ze-Mullite, ezaziwa ngokuba zizitena ze-mullite ezikhaphukhaphu okanye izitena ze-mullite zokufakelwa kwe-thermal, zenziwe nge-high-alumina bauxite clinker njengeyona nto iphambili ekrwada, kusetyenziswa amagwebu okanye iindlela zekhemikhali ukwenza isakhiwo se-porous, kwaye izithako zixutywe ngamanzi. sisitena esikhusela ubushushu esenziwe ngodongwe lweplastiki okanye udaka, olukhutshiweyo kwaye lugxothwe kwiqondo lokushisa eliphezulu.
Ubungakanani obuqhelekileyo be-mullite ye-poly light brick 230 * 114 * 65mm, ngokuqhelekileyo ubuninzi be-bulk yi-0.6-1.2g / cm3, kwaye ubushushu bokusetyenziswa yi-1300-1550 degrees. Ubume kunye nobukhulu bunokwenziwa ngokweemfuno zabathengi. Ngokutsho kobushushu bokusebenza, i-JM-23, i-JM-26, i-JM-28 inokwahlulwa ibe ziindidi ezintathu. Imveliso inokuqhagamshelana ngokuthe ngqo nomlilo, kwaye ineempawu zokumelana nokushisa okuphezulu, ubunzima bokukhanya, ukuhanjiswa kwe-thermal ephantsi, kunye nefuthe elibalulekileyo lokonga amandla.
