Gwiritsani ntchito zochitika za njerwa zopumira– zitsulo zotchinga za ladle

Njerwa zowonongeka zimagwiritsidwa ntchito popanga zitsulo za ladle ndipo zimakhala ndi nthawi yayitali ya moyo, ndipo ladleyo imakhalanso ndi malire a moyo. Ladle, yomwe imadziwikanso kuti ladle, ladle, ndi ladle yayikulu, ndi chida chofunikira chotenthetsera kwa opanga zitsulo, chomwe chimapangidwa makamaka ndi chipolopolo, chotchingira chotchinga, komanso makina otsetsereka a nozzle. Ladle imagwira ntchito monga kuyenga zitsulo zosungunuka. Kugwiritsa ntchito ladle lining mwachindunji zimakhudza linanena bungwe steelmaking. Choncho, pofuna kupititsa patsogolo moyo wa ladle pansi pa malo owonetsetsa kuti agwiritsidwe ntchito motetezeka, m’pofunika kuchepetsa kugwiritsidwa ntchito ndi mtengo wa zinthu zotsutsana ndi tani yachitsulo ndikuwonjezera kutentha kwa kutentha.

Ladle lining akhoza kugawidwa mu ntchito wosanjikiza, wosanjikiza okhazikika, slag mzere wosanjikiza, kutentha kutchinjiriza wosanjikiza ndi zina zotero. Kwa zinthu zosanjikiza zokhazikika, poganizira zinthu ziwiri zosungira kutentha ndi kulowa mkati mwachitsulo chosungunuka, ma aluminium apamwamba amasankhidwa. Pofuna kupititsa patsogolo ntchito yake yotsuka kutentha, njerwa ya mullite yopepuka imamangidwa pakati pa aluminiyamu yapamwamba kwambiri ndi chipolopolo chachitsulo.

Chigawo chogwira ntchito cha pansi pa ladle chimakhala ndi mphamvu yachitsulo chosungunuka komanso kupanikizika kwakukulu kwa static, kotero corundum castable imasankhidwa. Njerwa za magnesia-carbon zimamangidwa mozungulira njerwa zolowera mpweya wabwino komanso njerwa zapamphuno, zomwe zimathandizira kuphatikizika ndi kukonza ndikuletsa kukulitsa kwambiri. Kugwira ntchito kwa khoma lovala kumakhudzidwa ndi kuyamwa kwa kaboni kwachitsulo chosungunula, kukokoloka kogwedera ndi kukokoloka kwa slag panthawi yoyenga. Gawoli liyenera kukhala ndi kukana kukokoloka kwabwino, kukana kukokoloka, komanso kukana kwa okosijeni. Corundum castable imagwiritsidwa ntchito. Kumanga njerwa za magnesia-carbon pa mzere wa slag kumafuna mphamvu zotsutsa-oxidation ndi zotsutsana ndi kukokoloka.
