Izitena zodongwe

1. Izitena zodongwe ezinyaweni ezenziwe nge-arch-foot zenziwe nge-50% yodongwe oluthambileyo kunye ne-50% yodongwe olomeleleyo oluqhotyoshelweyo, luxutywe ngokwemfuno ethile yesayizi yamasuntswana, kwaye emva kokubumba kunye nokomisa, zitshiswa kubushushu obuphezulu obuyi-1300 ukuya kwi-1400 ℃. Izitena ezakhiwe ngodongwe ziyimveliso etyhidiweyo engenamandla, enokumelana nokhukuliseko lwe-asidi ye-asidi kunye negesi eneasidi, kwaye inokumelana kancinci nezinto zealkaline. Izitena zodongwe zineempawu ezintle zokufudumeza umzimba kwaye ziyamelana nengqele ekhawulezayo kunye nobushushu obukhawulezayo.

Izitena ezenziwe ngodongwe eziveliswe yinkampani yethu zisekwe kwimveliso yezitena zodongwe eziqhelekileyo, kusetyenziswa izinto ezikumgangatho ophezulu zokulungisa izinto njengezona zinto ziphambili zenziwe, ukongeza ixabiso elifanelekileyo lezinto ezincedisayo kunye nezinye izongezo, emva kokugaya, ukuxuba kunye noxinzelelo oluphezulu Ukubumba, emva koko kugxothwe ngokufanelekileyo Kuguqula isigaba se-mullite yikristale kumaqondo obushushu, kwaye imveliso eseleyo inezinto ezinobuncwane ezifanelekileyo, ukuze kuqinisekiswe ukuba isitena esenziwe ngodongwe sine-refractoriness ephezulu, ubuninzi bexinene lobuninzi, i-porosity ephantsi, ukusebenza okuhle kobushushu obuphezulu kunye nozinzo lwevolumu elungileyo.

1. Ukuchithwa kwakhona kwezitena ezenziwe ngodongwe ngu-1580 ~ 1730 ℃.

2. Layisha ubushushu obuthambisa: Ngenxa yokuba izitena zodongwe zinendawo engamanzi kumaqondo obushushu asezantsi kwaye ziqala ukuthambisa umlinganiso, ziya kukhubazeka ukuba zichanekile kwimikhosi yangaphandle, ngoko ke ubushushu obuthambisa izitena zodongwe busezantsi kakhulu kunenkunkuma, kuphela malunga ne-1350 ℃.

3. Ukuxhathisa ngeSlag: Izitena zodongwe zizinto ezinokwenzakalisa ezingenamandla. Banokuxhathisa ukhukuliseko lwe-acid slag, kodwa ukumelana kwabo ne-alkaline slag kubuthathaka kancinci.

4. Ukuzinza kweThermal: Ukuqina okwandisayo kokuqina kwezitena zodongwe kuncinci, ngenxa yoko ukuzinza kwe-thermal kulungile. Inani lokupholisa amanzi kwi-850 ° C ngokubanzi li-10 ukuya kwi-15 amaxesha.

5. Uzinzo lwevolumu: Izitena zodongwe ziya kuphinda zisebenze kumaqondo obushushu aphezulu, anciphisa umthamo wezitena. Ngexesha elifanayo, isigaba samanzi siveliswa. Ngenxa yengxwabangxwaba yomphezulu wenqanaba lolwelo, amasuntswana aqinileyo asondelelene, iporosity isezantsi, kwaye umthamo wezitena uyancitshiswa. Ke ngoko, isitena sodongwe sinepropathi yokuncipha kwentsalela kubushushu obuphezulu. ,

2. Eyona njongo yezitena zodongwe:

1. Izitena zodongwe zisetyenziselwa ukwakha izitena zodongwe, izitovu zokudubula, izitovu ezishushu, amaziko entsimbi, amaziko avulekileyo kunye neziko lombane, apho izitena zodongwe zisetyenziswa kubushushu obusezantsi. Izitena zodongwe zisetyenziselwa imigqomo yentsimbi, izitena zeenkqubo zokuphosa, amaziko okufudumeza umlilo, amaziko okunyanga ubushushu, amagumbi okutsha, iiflu, iitshimini, njl njl.

2. Izitena zodongwe ziyimichiza ene-asidi engenamandla, enokuthintela ukhukuliseko lwe-slag ene-asidi kunye negesi ene-asidi, kwaye inokumelana kancinci nezinto zealkaline. Izitena zodongwe zineempawu ezintle zokufudumeza umzimba kwaye ziyamelana nengqele ekhawulezayo kunye nobushushu obukhawulezayo.

3. Ukubuyiselwa kwezitena zodongwe kuyathelekiswa nokwenziwe ngezitena zesilika, ukuya kuthi ga kwi-1690 ~ 1730 ℃, kodwa iqondo lobushushu elithambileyo liphantsi komthwalo lingaphezulu kwama-200 ℃ ezantsi kunalawo wezitena zesilica. Ngenxa yokuba isitena sodongwe sinee-mullite crystals ezinobunkunkqele obuphezulu, ikwaqulathe phantse isiqingatha senqanaba lokunyibilika eliphantsi.

Kwiqondo lobushushu elingu-4 ~ 0 ℃, umthamo wezitena zodongwe uyanda ngokufanayo nokwanda kwamaqondo obushushu. Umjikelo wokwandiswa komgama ulinganiselwe kumgca othe ngqo, kwaye inqanaba lokwandiswa komgama li-1000% ~ 0.6%, elisiqingatha nje kuphela saloo zitena zesilica. Xa ubushushu bufikelela kwi-0.7 ℃ kwaye buqhubeke ukwanda, ivolumu yayo iya kuqala ukuncipha kwixabiso lokwanda. Intsalela eshiyekileyo yezitena zodongwe ikhokelela ekukhululekeni kwamalungu omdaka kumatye, oko kuyeyona nto iphambili kwizitena zodongwe. Xa ubushushu budlula i-1200 ° C, izinto ezinyibilikayo eziphantsi kwizitena zodongwe ziyanyibilika ngokuthe ngcembe, kwaye amasuntswana acinezelwe ngokuqinileyo ngokuchasene nomnye ngenxa yexinzelelo lomhlaba, okukhokelela ekunciphiseni kwevolumu.

5. Ngenxa yobushushu obuthomalalisa ubushushu bezitena zodongwe, iyancipha kumaqondo obushushu aphezulu, kwaye ukuqhuba kwayo kwe-thermal yi-15% -20% isezantsi kunaleyo yezitena ze-silica, kwaye amandla ayo oomatshini abi kakhulu kunalawo ezitena zesilica. Ke ngoko, izitena zodongwe zinokusetyenziselwa injongo yesibini yeecoke ze-coke. Amacandelo afana nodonga lokutywina lwe-regenerator, izitena ezincinci zokufakelwa kwezitena kunye nezitena zokujonga indawo yokuhlaziya, izitena zomnyango wezitena, uphahla lomlilo kunye nezitena zerin, njl njl.

3. Udongwe olwenziwe ngokutsha:

1. Iimveliso zahlulwe zangamabakala amathathu (NZ) -42, (NZ) -40 kunye (NZ) -38 ngokwemiqondiso yomzimba kunye neekhemikhali.

2. Ukuhlelwa kwemveliso kungqinelana nezibonelelo zeYB844-75 “Uhlobo kunye nenkcazo yeeMveliso eziPhambeneyo”. Ngokubanzi yahlulwe yohlobo oluqhelekileyo, uhlobo ngokubanzi, uhlobo olukhethekileyo, uhlobo olukhethekileyo, kwaye lunokwenziwa ngokukodwa ngokweemfuno zomsebenzisi.

3. Ubume kunye nobungakanani bemveliso buhlangabezana neemfuno ze-GB2992-82 “Ngokubanzi ngokuBumba kweBrick kunye neSayizi”. Ukuba akukho hlobo lwezitena lufunwa ngumthengi kumgangatho osemgangathweni, luya kuveliswa ngokwemizobo yomthengi.

4. Ubukhulu bezitena zodongwe T-38: 230 * 114 * 65/55

Ukusetyenziswa kwezitena zodongwe ezinyaweni: zisetyenziswa ikakhulu kwizibhuseli ze-thermal, iigilns kilns, iicement kilns, iizichumisi zegesi ezichumisayo, iivenkile zokuqhushumbisa, amaziko ashushu, iindawo zokubamba, izitovu zombane, izitena zokuphosa nokugalela intsimbi, njl.

Iimpawu zomzimba kunye neekhemikhali:
