Modern steelworks involve the three production stages: steelmaking, refining, and continuous casting. In steelmaking–continuous casting, a ladle corresponds to the furnace (smelting molten steel converter) used in container production.
Ladles are generally cylindrical, with an open top, and a small offcentre casting nozzle in the base. They consist of an external steel shell (50-100 rnrn thick), and several layers of internal refractory lining (up to 400 mm). A refractory-lined steel lid can be used to cover the top of the ladle.
Under normal operating conditions, a vertical temperature gradient forms in the ladle. This thermal stratification is undesirable. It generally causes variations in casting temperature (degrading caster performance).

Viwanda vya kisasa vya kutengeneza chuma vina hatua tatu za utengenezaji: kutengeneza chuma, kuifuta, na kutengeneza chuma kwa kuendelea. Katika kutengeneza chuma <unk> kutengeneza chuma kwa kuendelea, chungu kinalingana na tanuru (kuyeyusha converter ya chuma iliyomwagika) inayotumiwa katika uzalishaji wa chombo. Ladles ni kwa ujumla cylindrical, na juu ya wazi, na ndogo offcentre kutupwa nozzle katika msingi. Ni pamoja na shell nje ya chuma (upana wa 50 rn) na tabaka kadhaa za ndani ya refractory (hadi 400 mm). Kifuniko cha chuma chenye mipako ya moto chaweza kutumiwa kufunika sehemu ya juu ya chungu. Chini ya hali ya kawaida ya uendeshaji, gradient ya joto ya wima huundwa katika chungu. Hii thermal stratification ni yasiyotakiwa. Ni kawaida husababisha tofauti katika joto kutupwa (kuharibu utendaji caster). Click to enlarge Kwa habari zaidi kuhusu ufumbuzi wetu refractory kwa ajili ya sekta ya chuma, tafadhali wasiliana nasi.
