Kev lag luam kev xav hloov ua kom tiav; Silicon Futurate nqi qhib qis dua

Kev xav ua lag luam tau raug hloov tawm tsam, thiab cov cua kev lag luam rau cov khoom lag luam dub tau hloov dua tshiab. Ferrroalloy Cov nqi ua tiav tau qhib qis dua thiab tab tom ua lag luam qis dua, nrog lub ntsiab silicon hlau sib cog lus ntau dua 3% thiab lub ntsiab manganese silicon daim ntawv cog lus ntau dua 2%.
