Silicon Barium

Silicon barium alloy (Si Ba) ndi inoculant yapamwamba kwambiri. Ndi aloyi yachitsulo yokhala ndi ntchito zapamwamba. Silicon barium Manoculants amagwiritsidwa ntchito ku chitsulo chotuwira, chitsulo choponyera nodular, chitsulo choponyera ductile ndi chitsulo choponyera vermicular. The Ba, Ca etc. mankhwala zinthu mmenemo ndi okhazikika. Poyerekeza ndi luso la graphitization la ferro silicon, limatha kusintha makulidwe osiyanasiyana a kapangidwe kagawo ndi kuuma kofanana komanso kukulitsa kuchuluka kwa gulu la eutectic komanso kuthamanga kwachuma ndikuchedwa. Kuchulukirachulukira komweku, katemera wa barium silicon amatha kukulitsa mphamvu zamakokedwe apamwamba 20-30N/mm2 kuposa silicon ya ferro. Fananizani ndi ferro silicon, pamene kuchuluka kwa zowonjezera kumasintha, kuuma kwa kutayira kumakhala kochepa. Pambuyo Spheroidizing mankhwala a chitsulo chosungunula anawonjezera barium pakachitsulo amene sangathe kuwonjezera chiwerengero cha graphite mpira ndi kusintha roundness komanso kuthetsa cementite ndi kumwaza kapena kuchepetsa phosphorous eutectic.

Ntchito:
1. Kwa okosijeni ndi kusinthidwa kwachitsulo, chitsulo choponyedwa ndi ma alloys.
2. Ali ndi dephosphorizing action.
3. Chepetsani kuyera kwachitsulo chachitsulo
4. Kupititsa patsogolo kukhazikika kwa calcium muzitsulo zosungunuka, kuchepetsa kuphulika kwa calcium.
