FeCr SMS group What distinguishes high-carbon ferrochrome is the carbon content of 4-8%. Medium-carbon chrome alloys and low-carbon FeCr are produced in combined process stages. Now the annual production of the plant melt shop No. Along with Metix SMS group is a leading supplier of new FeCr furnaces and has also
CN104313309A - Technology and system for producing An electric furnace alloy smelting technology is omitted the latent heat of the stainless steel by a submerged arc furnace and AOD furnace duplex process. 60% other alloys of ferronickel water 35% high carbon ferro-chrome 5% quality
WO2001086006A2 - Improved process for the production of The carbon reduction process is carried out in a submerged arc furnace. C22C38/36 Ferrous alloys e.g. steel alloys containing chromium with more than 1.7% The reason is high carbon ferro chrome which is another variety of ferro chrome Addition of chromite ore and its smelting in a bath of normal liquid pig iron to
Ferroalloy Production - EPA 12.4.1 General. Ferroalloy is an alloy of iron with some element other than carbon. The principal ferroalloys are those of chromium manganese and silicon. Chromium In most cases the submerged electric arc furnace produces the desired product directly. It submerged arc process is a reduction smelting operation.
鉻鐵 / Ferro Chrome - 澄柏國際股份有限公司- NCM CORP 低矽高碳鉻鐵 Low Si High Carbon Ferro Chrome： Ferro-chrome Fe-Cr is an alloy comprised of iron Fe and chromium Cr . ore consisting oxides of Cr and Fe using an electric submerged arc furnace SAF Its melting point is greater than 1500 deg C and boiling point is in the range of 2700 deg C to 3000 deg C.
Control of silicon in high carbon ferrochromium produced in 18 Jul 2013 High carbon ferrochromium produced in a submerged arc furnace may contain as much as 4%Si. A high level of silicon in this alloy is not desired. practices lead to difficulties in tapping and to reduced recovery of chromium.
