Low Carbon Ferro Chrome Ferro Chrome is a type of ferroalloy that is used to manufacture ball-bearing steels, acid-resistant steels, tool steels and alloy steels. The electric arc carbothermic removal of chromite produces ferrochrome. In South Africa, Kazakhstan and India, which have significant domestic chromite resources, much of the global production is produced. The composition of Ferro chrome (FeCr) is iron and chromium consisting between 70% and 50% of chromium. The largest consumer of this metal is the stainless steel and tool steel. Ferro Chrome is chromium which confers a remarkable corrosion resistance to stainless steel. Application of Ferro Chromium Chromium is one of the most flexible and commonly used alloy elements in steel. It offers corrosion and oxidation resistance, is a mild hardening agent, increases wear resistance and facilitates the preservation of useful intensity at elevated temperatures. Chromium is an irreplaceable part of all stainless steels; in fact, more than 70% of all chromium used in steel making is present in many steels. Building alloy steels, most of which contain less than 3% Cr, are often used in the tonnage use of chromium. Tool steels, super alloys and other specialized metals, while also high in chromium content, are manufactured in smaller amounts and are therefore lower in over-all chromium applications. Chromium is most widely used as ferrochrome. The carbon level is the most significant factor in deciding the price difference between the various ferrochrome grades. The widespread move towards duplex processing practices such as AOD, CLU, etc. has led to a major increase in the use of high-carbon ferrochrome.

Ferro chrome (FeCr) is an ferro alloy of chromium and iron, containing 50% to 70% chromium. The ferro chrome is produced by electric arc melting of chromite, an iron magnesium chromium oxide and the most important chromium ore. It can divide into Charge FeCr, Carbon FeCr, Low carbon FeCr and Micro carbon FeCr

Step1: chrome ore raw material is processed by water washing. Step2, drying raw materials to remove water; Step3, drying raw materials into the vibrating screen, screening out the size of the customer needs; Step4, the size of the sieve for magnetic separation, the purpose of iron and silicon removal. After magnetic separation, the chromium content reached more than 46% and the silicon content was less than 1%. Step5: package the finished product.
