Clay izitini ezikhanyisayo okwesithando somlilo

Izitini ze-clay refractory ze-blast furnaces kufanele zenziwe ngobumba obuphikisayo bolwelwesi lwezindonga zesithando somlilo. Izitini ze-clay refractory zezithando eziqhumayo zisetshenziselwa umphimbo, i-shaft, iziko, phansi komugqa omncane wesithando somlilo kanye ne-shaft yesithando somlilo esikhulu somlilo.

Izitini eziphikisayo zobumba zesithando somlilo zidinga amandla acindezelayo aphezulu ezinto ezingashi endaweni yokushisa yasekamelweni, ezingamelana nokulimala komsebenzi wesikhathi eside wezinto ezilahlwa kabusha; i-shrinkage encane yevolumu ngaphansi komsebenzi wesikhathi eside ekushiseni okuphezulu kunenzuzo ekugcineni ukujula komugqa wesithando somlilo; i-porosity ebonakalayo ephansi kanye ne-Fe:O. Amanzi aphansi anganciphisa ukunqwabelana kwesitshalo sekhabhoni emgodini we-vent futhi kuvimbele izitini eziphikisayo ekuvuvukeni nasekuxegisweni futhi zibhujiswe phakathi nayo yonke inqubo yokufaka isicelo; izinto ezincibilika phansi zikhiqizwa kancane. Izitini ze-clay refractory ze-blast furnaces zinezakhiwo ezingcono kunezitini zobumba ezijwayelekile.

Ukusatshalaliswa kwezingxenye eziphambanayo zezitini zobumba eziphikisayo zezithando eziqhumayo kunezidingo:

(1) Uma ingqikithi yobubanzi besipali ingeqi ku-0.25mm, ubude abunqunyelwe;

(2) Uma ingqikithi yobubanzi besipali ingu-0.26–0.5mm, ubude akumele budlule ku-15mm;

(3) Uma ingqikithi yobubanzi be-spall idlula u-0.50mm, akuvunyelwe.

Ukuqhekeka kwezingxenye eziphambanayo zezitini eziphikisayo zobumba kunezidingo:

(1) Uma ingqikithi yobubanzi besipali ingeqi ku-0.25mm, ubude abunqunyelwe;

(2) Uma ingqikithi yobubanzi besipali ingu-0.26–0.50mm, ubude akumele budlule ku-40mm;

(3) Ukuphalaza akuvumelekile lapho ububanzi buphelele bungaphezu kuka-0.5mm.
