Ezi mfuno zilandelayo zibekwe phambili kwi-furnace wall refractory materials:

1. I-refractoriness eyaneleyo

I-refractoriness yayo kufuneka ibe yi-1650 ~ 1780 ℃, kwaye ubushushu bayo bokuthambisa kufuneka bube ngaphezulu kwe-1650 ℃.

2. Ukuzinza kakuhle kwe-thermal

Ubushushu bodonga lwesithando somlilo buhlala buguquka rhoqo, kwaye udonga lwesithando somlilo luhlala luqhekeka ngenxa yokufudumeza okungalinganiyo, okunciphisa ubomi benkonzo yodonga lwesithando somlilo. Ke ngoko, njenge-refractory kwiziko lombane, kufuneka ibe nokuzinza okuhle kakhulu kwe-thermal.

3. Uzinzo lweekhemikhali olulungileyo

Ukuzinza kweekhemikhali zezinto eziphathekayo kuhambelana ngokusondeleyo nobomi bodonga lwesithando somlilo. Izinto ezifakwe eludongeni zesithando somlilo akufanele zihlanjululwe nge-hydrolyzed kwaye zihluke kwiqondo lokushisa eliphantsi, kwaye akufanele lihlanjululwe ngokulula kwaye lincitshiswe kwiqondo lokushisa eliphezulu. Akufanele kube lula ukwenza izinto ezincibilikayo eziphantsi kunye ne-slag ngexesha lenkqubo yokunyibilika, kwaye akufanele iphendule ngeekhemikhali kunye nezisombululo zetsimbi kunye nezongezo, kwaye aziyi kungcolisa izisombululo zetsimbi. .

4. I-coefficient yokwandiswa kwe-thermal encinci

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

5. Ineempawu eziphezulu zoomatshini

Kufuneka ikwazi ukumelana nokukhutshwa kwentlawulo kwindawo yokushisa ephantsi; 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. Ukusebenza kakuhle kwe-insulation

Umbane wodonga lwesithando somlilo akufanele uqhube umbane kumaqondo aphezulu, ngaphandle koko kuya kubangela ukuvuza kunye neesekethe zesikhashana, ezibangela iingozi ezinzulu.

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

8. Izibonelelo ezininzi kunye nexabiso eliphantsi.
