High carbon ferrochrome is a carbon reduction product intermittently outgoing from the furnace. It is produced from ferrochrome minerals in the electric smelting furnace for continuous smelting by using the silica as flux and carbon as reducing agent.

    High Carbon Ferrochrome is the solid solution of chromium, ferrum and carbon, complex compound of chromium, ferrum and carbon. The essential component is （Cr、Fe）7C3, silver-white metal, brittle. The specific weight is 6.5-6.7g/cm3, bulk specific weight is 3.8-4.0t/m3. The melting point is 1550℃, electric conduction. High Carbon Ferrochrome fulfill GB/T5683-1996 standard.

    High carbon ferrochrome is lump shape, each weight ≤15kg, size less than 20×20mm, no more than 5% of the total weight. No sonims inside. The product will crush, package and deliver according to buyer’s requirement.

    High carbon ferrochrome is the Base Material of Stainless Steel.

    Chromium is the only element to determine the attribute of stainless steel. All stainless steel contains chromium.

    In 1954, Krivsky came up with reducing the partial pressure of CO by vacuum or mixed gas (argon-oxygen) refining to produce stainless steel.

    In 1965, German Witten Company developed VOD Method, using high carbon ferrochrome produce stainless steel.

    In 1968, American Jocelyn Company developed AOD Technology to produce stainless steel by using high carbon ferrochrome.

    From now on, high carbon ferrochrome became the base material to produce stainless steel.

    Mintal Group introduce 2×69MVA OPKTM preheating closed furnace from Outotec. It can preheat the raw material and recycle the gas, which is low carbon, energy saving, environment friendly. The annual output is 300,000 tons high carbon ferrochrome.
