Ziziphi iimfuno ze impahla ye-lining yodonga lwesithando somlilo?

1. I-refractoriness eyaneleyo

Izinto eziphathekayo ezine-refractoriness ephezulu kune-1580 ° C zibizwa ngokuba yizinto eziphikisayo. Ukushisa okusebenzayo komgca wesithando somlilo se-induction ngokuqhelekileyo siphantsi kunokushisa kwentsimbi etyhidiweyo. Nangona kunjalo, ngokusekwe kwiimfuno zobomi bomgca wesithando somlilo, ubushushu obugqithisileyo okanye obuqhelekileyo bechibi elityhidiweyo kunye nedama elityhidiweyo kufuneka liqwalaselwe. I-refractoriness esetyenziswa kwisithando somlilo sentsimbi kunye nezixhobo ezinobushushu obuphantsi bokuthambisa zihlala zingakhuselekanga. Njengomrhumo wombane womlilo wentsimbi yokuhombisa,

I-refractoriness yayo kufuneka ibe yi-1650 ~ 1700 ℃, kwaye ubushushu bayo bokuthambisa kufuneka bube ngaphezulu kwe-1650 ℃.

2. Ukuzinza kakuhle kwe-thermal

Iziko lokungeniswa lixhomekeke kwi-electromagnetic induction ukutshintshisa amandla. Ukuze kuqinisekiswe ukuba isithando somlilo sinombane ophezulu, oku kwenza ukuba umbane wesithando somlilo usebenze kunye ne-radial enkulu yeqondo lokushisa. Ukongeza, iqondo lokushisa lomlilo wesithando somlilo lihlala litshintsha ngenxa yempembelelo yokutshaja, ukucofa, kunye nokuvalwa kwesithando somlilo ngexesha lenkqubo yokusebenza kwesithando somlilo, kwaye uphahla lwesithando somlilo luhlala luqhekeka ngenxa yokufudumeza okungalinganiyo, okunciphisa ubomi benkonzo. yophahla lweziko. Ke ngoko, njenge-refractory kwiziko lombane, kufuneka ibe nokuzinza okuhle kakhulu kwe-thermal.

3. Uzinzo lweekhemikhali olulungileyo

Ukuzinza kweekhemikhali zezinto eziphathekayo kuhambelana ngokusondeleyo nobomi bomgca wesithando somlilo. Izinto eziphathekayo akufanele zifakwe i-hydrolyzed kwaye zihluke kwiqondo lokushisa eliphantsi, kwaye akufanele lihlanjululwe ngokulula kwaye lincitshiswe kumaqondo aphezulu. Akufanele yenze lula izinto ezincibilikayo ezincibilikayo kunye ne-slag ngexesha lenkqubo yokunyibilika, kwaye akufanele iphendule ngeekhemikhali kunye nezisombululo zetsimbi kunye nezongezo, kwaye ayiyi kungcolisa izisombululo zetsimbi.

4. I-coefficient encinci yokwandiswa kwe-thermal

Umthamo kufuneka uzinzile ngokutshintsha kweqondo lokushisa, ngaphandle kokwandiswa ngokukhawuleza kunye nokunciphisa.

5. Ineempawu eziphezulu zoomatshini,

Kufuneka ikwazi ukumelana nokukhutshwa kwentlawulo yendawo xa isinyithi sikwiqondo lokushisa eliphantsi; xa intsimbi ikwimo yobushushu obuphezulu obunyibilikisiweyo, kufuneka ikwazi ukumelana noxinzelelo olungagungqiyo lwentsimbi etyhidiweyo kunye nefuthe elinamandla lombane elishukumisayo; ukugqoka ukuxhathisa kunye nokuxhatshazwa kwe-corrosion phantsi kokutshatyalaliswa kwexesha elide lentsimbi etyhidiweyo.

6. Ukugquma kakuhle

Umbane wesithando somlilo akufanele uqhube umbane phantsi kweemeko eziphezulu zeqondo lokushisa, ngaphandle koko kuya kubangela ukuvuza kunye neesekethe zesikhashana, okubangela iingozi ezinzulu.

7. Ukwakhiwa kwezinto eziphathekayo kukuhle, kulula ukuyilungisa, oko kukuthi, ukusebenza kwe-sintering kungcono, kwaye ukwakhiwa kwesithando somlilo kunye nokugcinwa kukulungele.

8. Izibonelelo ezininzi kunye namaxabiso aphantsi.

Akunzima ukubona ukuba iimfuno zezixhobo eziphikisayo kwiziko le-induction zingqongqo kakhulu, kwaye akukho phantse izinto zendalo eziphikisayo ezinokuhlangabezana nezi mfuno zingasentla. Oku kufuna ukukhethwa kwezinto ezifanelekileyo zokuphikisa ngokwemiqathango eyahlukeneyo yokusetyenziswa. Kwangaxeshanye, izibonelelo zamaminerali zendalo kufuneka zihlanjululwe, zidityaniswe kwaye zihlaziywe ukuze ukusebenza kwazo kuhambelane neemfuno zeziko lokungeniswa.
