12L14 Chitsulo Chodula Chaulere

A Chitsulo chokhala ndi sulfure ndi phosphorous yapamwamba kuposa masiku onse opangidwa kuti apange zigawo za zida zamakina othamanga kwambiri komanso zodziwikiratu. Chitsulo chaulere chimapangidwa ngati ndodo, ndipo chimakhala ndi 0.08-0.45 peresenti ya carbon, 0.15-0.35 peresenti ya silicon, 0.6-1.55 peresenti ya manganese, 0.08-0.30 peresenti ya sulfure, ndi 0.05-0.16 peresenti phosphorous. Kuchuluka kwa sulfure kumapangitsa kuti pakhale ma inclusions (mwachitsanzo, manganese sulfide) otayidwa m'mbali mwa njere. Zophatikizika izi zimathandizira kumeta ndikulimbikitsa kugaya komanso kupanga chip mosavuta. Pazifukwa izi, zitsulo zopanda malire nthawi zina zimaphatikizidwa ndi lead ndi tellurium.

12L14 ndi mtundu wa resulfurized ndi rephosphorized mpweya zitsulo kwa ufulu-kudula ndi Machining ntchito. Chitsulo chopangidwa (chitsulo chodziwikiratu) chimakhala ndi makina abwino kwambiri komanso mphamvu zochepa chifukwa cha zinthu zophatikizika monga Sulfure ndi lead, zomwe zimatha kuchepetsa kukana ndikuwongolera kumaliza ndi kulondola kwa magawo amakina. 12L14 zitsulo wakhala chimagwiritsidwa ntchito popanga mbali mwatsatanetsatane chida, mbali galimoto ndi mbali zofunika za mitundu yosiyanasiyana ya makina, ntchito mmene kuphatikizapo bushings, shafts, amaika, couplings, zovekera ndi etc.
