Yintoni umahluko phakathi izitena ezikhanyelayo nezitena ezibomvu?

1. Imathiriyeli ekrwada kunye nenkqubo yokuvelisa

1. Izitena eziphikisayo

Izitena eziphikisayo zizinto eziphikisayo ezenziwe ngodongwe olunqabileyo okanye ezinye izinto ezinqabileyo ezinqabileyo, ezikhanyayo eziphuzi okanye ezimdaka. Isetyenziswa ikakhulu ukwakha amaziko okunyibilikisa kwaye inokumelana namaqondo obushushu aphezulu ayi-1,580℃-1,770℃. Ikwabizwa ngokuba yi-firebrick.

2. Isitena esiBomvu

Kwimveliso yezitena, umlilo omkhulu usetyenziselwa ukutshisa izitena ngaphakathi nangaphandle, uze ucime umlilo ukuvumela i-oven kunye nezitena ukuba zipholile ngokwemvelo. Ngeli xesha, umoya kwi-oven ujikelezwe kwaye i-oksijini yanele, yenza umoya we-oxidizing ofanelekileyo, ukwenzela ukuba i-iron element kwizitena ifakwe kwi-iron trioxide. Ekubeni i-iron trioxide ibomvu, iya kubonakala ibomvu.
