เหล็กโครเมียม, โครเมียมและโลหะผสมเหล็กประกอบด้วยเหล็ก. เป็นสารเติมแต่งเหล็กโลหะผสมที่สำคัญชนิดหนึ่ง. Ferrochrome according to different carbon content is divided into high carbon ferrochrome (8% carbon for 4 ~ 6), the carbon ferrochrome (0.5 ~ 4% 6) containing carbon, low carbon ferrochrome (0.15 ~ 0.50% 6) containing carbon, low carbon ferrochrome (0.06%) containing carbon, superfine carbon ferrochrome (carbon is less than 0.03%), and silicon chromium alloy, ferrochrome nitride, ฯลฯ.

Low carbon ferrochrome intensified treatment more difficult, power consumption is big, the cost is high, 2% carbon ferrochrome under 6, suitable for stainless steel, acid steel smelting and other low carbon chromium steel. Carbon content more than 4% of ferrochrome, commonly used to ball bearing steel and auto parts with steel smelting, ฯลฯ. เกี่ยวกับ 5% of chromium ferrochrome, turn can be used as an alloy of iron and chromium

ใช้ XRF สเปกโตรมิเตอร์ในการวิเคราะห์การหาปริมาณเฟอร์โรโครม

X-ray Fluorescence Spectrometer (เอ็กซ์ – ray Fluorescence Spectrometer, hereinafter referred to as: XRF Spectrometer), is a rapid, nondestructive material measurement method. การเรืองแสงด้วยรังสีเอกซ์ (เอ็กซ์ – ray fluorescence, เอ็กซ์อาร์เอฟ) is to use high-energy x-rays or gammaRays hit material inspired subprime x-rays. This phenomenon has been widely used for elemental analysis and chemical analysis, especially in metal, กระจก, ceramics and construction materials of investigation and research, geochemistry, forensic medicine, archaeology and art use tablet of ferrochrome samples prepared by this case, coupled with the fly, scientific instruments designed for the analysis of ferrochrome manufacture EDX9000B spectrometer to analyze the determination of chromium iron, has obtained the good inspection Measuring accuracy and stability.
