Xom ashyoga qo'yiladigan talablar quyidagilar:
(1) Molibdenni qovurish uchun S<0.10%, Cu<0.6%, and Pb<0.5%. The actual ingredients are: Mo48.5%~52%, S0.04%~0.07%, P0.01%~0.02%, Cu0.1%~0.5%, Pb0.2%~0.5%, FeO3%~5%, SiO28%~14%, CaO2%~4.5%. 5% to 10% of the total molybdenum is in the form of MoO2, which should be considered when calculating the reaction heat. The particle size is <15mm, of which >10 mm 10% dan kamroqni tashkil qiladi va<2mm accounts for about 60%. (2) Ferrosilicon powder contains Si75%~77%; the particle size is <1mm.
ferromolibden kukuni narxi
(3) Aluminum particles contain Al>90% va Cu<0.1%; the particle size is <3mm, and the part <0.5mm shall not exceed 30%.
(4) Iron ore contains Fe>65%, S<0.05%, P<0.05%, C<0.30%; particle size<1mm. Iron oxide scale or iron concentrate can be used instead.
(5) Po'lat qoldiqlari oddiy karbonli po'lat qoldiqlari va jingalak uzunligi<50mm.
(6) Fluorite contains CaF2>90%. Zarrachalar hajmi<3mm.
Ferro-molibden qotishmasining narxi
(7) Saltpeter contains NaNO3>90%. Eritma jarayonida chayqalishlar va baxtsiz hodisalar oldini olish uchun barcha xom ashyo yaxshilab quritilishi va namlikni o'z ichiga olmaydi. Xom ashyo hisoblangan nisbatga muvofiq aniq tortiladi, aralashtirgichga solinadi va bir tekis aralashtiriladi, so'ngra eritish pechiga qo'yiladi va yuqori ateşleme usuli yordamida eritiladi.
