12L14 Kudula kwaulere

A Zitsulo zoposa nthawi zonse za sulfur ndi phosphorous zomwe zimapangidwa kuti zipangidwe ndi zigawo zothamanga kwambiri komanso zida za semiatomatic. Zitsulo zodula zaulere zimapangidwa mu mawonekedwe a ndodo, ndipo ili ndi 0,08-0,45 peresenti ya kaboni, 0.15-0,35 peresenti silicon, 0.6-1.55% manganese, 0.08-0.30 peresenti sulfur, ndi 0.05-0.16 peresenti phosphorous. Zolemba zapamwamba zimayambitsa kukhazikitsidwa kwa zophatikizika (mwachitsanzo, Mangudese Sulfatide) omwe adataya mbewu. Izi zimathandizira kubereka ndikuthandizira kukopera komanso kosavuta. Pazifukwa izi, zitsulo zaulere nthawi zina zimathandizira kuti azitsogolera ndi mawu.

12L14 Ndi mtundu wa kubwezeretsanso masitete a fodya odulira ndi kugwiritsa ntchito njira zodulira. Chitsulo champhamvu (chitsulo chokha) chili ndi mphamvu zambiri komanso mphamvu zotsika chifukwa cha zinthu zoyatsira ngati zinthu zokongola ngati zisungunuke ndikuwongolera kuthetsa ndi kuwongolera magawo. 12L14 Zitsulo zagwiritsidwa ntchito kwambiri popanga zida zowongolera magawo, magawo amtundu wamagalimoto ndi magawo ofunikira pamitundu yosiyanasiyana
