Izitena zeSillimanite: Indlu yaMandla eNxaxheba kwiMisebenzi yoShishino

Kwiimeko zemizi-mveliso apho amaqondo obushushu aphezulu, uxinzelelo, kunye nokunxiba izinto zomngeni, izisombululo ezithembekileyo zibalulekile.Izitena zeSillimanitebagqame “njengehashe lomsebenzi,” elineepropathi ezikhethekileyo eziphakamisa ukusebenza kakuhle, ukunciphisa iindleko, kunye nokuphucula umgangatho wemveliso kuyo yonke isinyithi, iiseramikhi, kunye nokuveliswa kweglasi. Nasi isizathu sokuba belukhetho oluphezulu kwihlabathi liphela

1. Iimpawu eziphambili: Yintoni eyenza izitena zeSillimanite zibe yimfuneko

Ephuma kwi-aluminosilicate mineral sillimanite, ezi zitena zibonelela ngeenzuzo ezintathu ezingenakunqotshwa:

Ukuguquguquka okuphezulu kakhulu:Ngeqondo lokunyibilika elingaphezu kwe-1800°C, zixhathisa ubushushu obugqithisileyo (obubaluleke kakhulu ekunyibilikeni kwesinyithi nokunyibilika kweglasi, apho iqondo lobushushu lingaphezu kwe-1500°C) ngaphandle kokujija okanye ukuhla.

Ukwandiswa kobushushu obuphantsi:Izinga elingaphantsi kwe-1% kwi-1000 ° C lithintela ukuqhekeka kumothuko we-thermal, iqinisekisa ukuqina kwindawo yokupholisa ngebhayisikile efana neziko lokuqhushumba.

Ukuxhathisa okuPhezulu:Zixinene kwaye ziqinile, ziyamelana nokurhawuka kwisinyithi esinyibilikisiweyo/i-slag kunye nokhukuliseko lwekhemikhali olusuka kwi-acids/alkalis-isitshixo sokusetyenzwa kweekhemikhali kunye ne-metallurgy.

Ezi mpawu ziguqula izitena ze-sillimanite ukusuka "kwi-nice-to-have" ukuya ekubeni "kufuneka ube nayo" ukuze usebenze kakuhle.

2. I-Metallurgy: Ukuphucula iMveliso yeNsimbi kunye neNsimbi

Ishishini le-metallurgical lithembele kakhulu kwizitena ze-sillimanite zezixhobo ezigxininiswe ngubushushu:

ILinings yokuqhushumba kwesithando somlilo:Ukudibanisa "indawo eshushu" (i-1500-1600 ° C) yeentsimbi zokuvelisa isinyithi, zigqithisa izitena zomlilo zendabuko. Iplanti yentsimbi yaseIndiya ibone ixesha elide lokuhlala eziko kunye nama-25% eendleko eziphantsi zokulilungisa emva kokulitshintsha.

Tundish & Ladle Linings:Ukunciphisa ukungcoliseka kwesinyithi kunye nokwandisa ubomi belinen ukuya kuthi ga kuma-40% (ngokomenzi wentsimbi waseYurophu), aqinisekisa ukuphathwa kwentsimbi etyhidiweyo egudileyo.

Imikhumbi yeDesulfurization:Ukuxhathisa kwabo kwi-slag etyebileyo ngesulfure kugcina ukungaguquguquki, kunceda ukuhlangabezana nemigangatho engqongqo yokucoceka kwentsimbi

Kwi-metallurgists, izitena ze-sillimanite zilutyalo-mali olucwangcisiweyo kwimveliso

3. IiCeramics: Ukunyusa iThayile, iWare yeSanitary kunye neeCeramics zobuGcisa

Kwi-ceramics, izitena ze-sillimanite zisebenza iindima ezimbini eziphambili:

Kiln Linings:Ukugcina ubushushu obufanayo (ukuya kwi-1200 ° C) kwiindawo zomlilo, ukwanda kwazo okuphantsi kuthintela umonakalo. Umvelisi weethayile waseTshayina unciphise amatyala ombane nge-10% emva kokulungiswa ngokutsha, nge-15-20% esezantsi yokusetyenziswa kwamandla xa iyonke.

I-Raw Material Additive:Ground ibe ngumgubo (5-10% kwimixube), yongeza amandla omatshini (25% yamandla aphezulu aguquguqukayo) kunye nokuzinza kwe-thermal (30% ngaphantsi komonakalo wokothuka kwe-thermal) kwiiseramikhi zobugcisa.
