鉻鐵礦粉325mesh Ferro Chromite flour 325目
別稱：鉻鐵礦粉325目,鉻粉325#,洛礦粉,洛鐵礦粉,鉻礦砂粉末,鉻鐵礦粉末, Chromite powder, Chromite flour, Iron chromite flour, Ferro Chromite flour, Iron Chrome flour, Iron chromium powder, Chromite flour 325#, Iron chromite powder 325mesh等等
鉻鐵礦粉325mesh Ferro Chromite flour 325目是一種天然的無機礦物粉末。它是一種以FeO和Cr2O3為主要成分的復合礦物。鉻礦粉的質(zhì)量來自于不同品位的鉻礦砂的品質(zhì)。我廠選用46-50%含量和40-42%的非洲鉻礦為原料，采用先進的研磨設(shè)備和備制方法，得到適合色料和鑄造冶金領(lǐng)域的鉻鐵礦粉。
Iron Chromite flour is a natural inorganic mineral powder. It is a composite mineral mainly composed of FeO and Cr2O3. The quality of chromite flour comes from the quality of chromite sand of different grades. Our factory uses African chromite with a content of 46-50% and 40-42% as raw materials, and adopts advanced grinding equipment and preparation methods to obtain chromite flour suitable for pigments and casting metallurgy fields.
