Identifikazzjoni ta 'kwalità ta' trab tal-kromju tal-ħadid b'karbonju għoli

Ferrokrom tal-karbonju għoli bħala xiri kbir ta 'prodotti, huwa importanti ħafna li jiġi identifikat tajjeb jew ħażin tiegħu. Il-produzzjoni tal-ferrokrom tal-karbonju għoli teħtieġ materja prima ferroalloy huma minerali tal-kromju, kokk u silika, sabiex taġġusta t-tip ta 'gagazza, jeħtieġ li żżid ċertu ammont ta' rmied abjad jew dolomit, manifatturi ta 'ferrokrom tal-karbonju għoli għal materja prima huma rekwiżiti għoljin ħafna, jeħtieġu għolja kontenut ta 'elementi utli, prestazzjoni tajba, daqs tal-partiċelli tajjeb, u ħafna iffrankar tal-enerġija u tnaqqis fil-konsum.
