Ukusasazeka uhlobo izitena breathable engundoqo

Igama Product: Ukusasazeka uhlobo izitena breathable engundoqo

Udidi: Uhlobo lokusasazeka kwesitena esiphefumlayo

Ezichithachithekileyo izitena ezingena ngaphakathi emoyeni ine-porosity ephezulu kunye nokuvumeleka. Kwimveliso yokwenyani, ngokudibanisa iikhabhoni eziqulathe iikhompawundi kumxube, izinto zinokutshiswa kubushushu obuphantsi ngaphandle kwentsalela, ke iporosity yokuqala ingafumaneka ngokutshisa izinto eziphakathi kubushushu obuphantsi. Ubunzima bohlobo-lwezitena ezivumayo zomoya zisasazwa ngeendawo ezingena phakathi ngobungakanani obahlukeneyo. Xa ukuvutha komoya kumisiwe ngexesha lokusetyenziswa, isinyithi kunye ne-slag kwiladle iya kungena kwiindawo ezinzulu zesitena esinokungena emoyeni ngezi pores, ngaloo ndlela zivelise indawo yokusebenza. Iindawo eziqinileyo. Xa i-ladle imisiwe okanye xa umoya uqaliswa kwakhona, umphezulu osebenzayo wezitena ezinokungena emoyeni uhlala ungenelelwa kwaye ukhukuliswe yintsimbi etyhidiweyo, ebangela ukuba ii-pores zivalwe, zikhutshwe okanye zihluthwe.

Performance:

1. Ukuxhathisa i-Slag

Ukuze kuphuculwe uxhathiso lwezixhobo ze-slag kunye nokumelana nokungena kwe-iron, i-Cr2O3 okanye inxenye ye-chromium corundum idla ngokudityaniswa kwi-corundum spinel izitena zomoya ezivumayo. I-Cr2O3 kunye ne-Al2O3 zinesakhiwo esifanayo sekristal. I-Cr2O3 ayiphuculi kuphela ukuxhathisa kwezinto ze-slag, kodwa ikwonyusa i-engile yokumanzisa phakathi kwezinto kunye nentsimbi etyhidiweyo, kwaye iphucula kakhulu ukucinywa kwemingxunya yezitena ezinokuphefumla ngenxa yokungena kwentsimbi etyhidiweyo.

Sebenzisa i-Cr2O3 umgubo ocolekileyo kunye ne-Al2O3 kubushushu obuphezulu ukwenza isisombululo esiqinileyo se-aluminium-chromium kunye nesigaba seglasi esele sine-chromium, isigaba esingamanzi esenziwe xa sidibana ne-slag kwinkqubo yokunyibilikisa intsimbi inyibilikile, ngaloo ndlela Ukuthintela i-slag eyenziwe ngentsimbi etyhidiweyo ekuchaphazelekeni kukonakala kwezitena; Kwangaxeshanye, inokufunxa i-iron oxide kunye ne-magnesium oxide kwi-slag, kwaye yenze i-spinel eshinyeneyo kumaleko osebenzayo wezitena zomoya, eziphucula ukuxhathisa kwe-slag kwisitena somoya.

Nangona kunjalo, emva kokongeza i-Cr2O3 kwimathiriyeli, emva kokudubula okushushu okanye ukusetyenziswa, i-Cr3 + ifakwe ioksijini kwi-Cr6 +, enetyhefu kwaye ingcolisa indalo. Ke ngoko, kulondolozo lwamandla kunye nokukhuselwa kwendalo esingqongileyo, ukusetyenziswa kweCr2O3 kufuneka kuthintelwe kangangoko kunokwenzeka, kwaye ngokubuyisela izinto ezingasetyenziswanga, ukusebenza kobushushu obuphezulu ngaphandle kokongeza iCr2O3 kunokufikelela kwinqanaba lokongeza iCr2O3.

2. ukumelana ukothuka Thermal

Eyona ndlela iphambili yomonakalo yezitena ezinokungena emoyeni ngumonakalo wokothuka oshushu. Ngokunyuka okuqhubekayo kweqondo lokushisa ngokuthepha, kukho umahluko omkhulu wobushushu phakathi kokusebenza kunye nomsebenzi ongaphakathi kwindawo yokusebenza yesitena somoya, esifuna ukuba umbandela ube nokuxhathisa okuphezulu kobushushu. Isigaba se-spinel singeniswa kwi-castable, kwaye ukuxhathisa ukutshitshiswa kwesitena esinokungena emoyeni kuya kuphuculwa.

I-oxide okanye i-non-oxide eyongezwe kwisitena somoya esenza isisombululo esomeleleyo ngesixa sobushushu obuphezulu, inyusa ubushushu obuphezulu besitena, iphucula ukuthamba kwesitena, kwaye iyakwala ukukhukuliseka kwesitena esingena umoya I-slag etyhidiweyo kwiladi. Emva konyango olushushu lobushushu kwisitena esinokungena emoyeni, ukusebenza kwaso kuyaphuculwa ukuhlangabezana neemfuno zokusetyenziswa.
