Mar 12, 2021· Effective April 1, 2021 alloy surcharges on Ferromolybdenum, Nickel, LC & HC ferrochrome, HC ferromanganese and Ferrovanadium are outlined as follows. Alloy surcharges will be calculated monthly and charged as a separate line item to each invoice based on the steel grade.
Jul 14, 2020· Metallurgical industries use around 90% of mined ferrochrome-grade chromite ore from which stainless steel industry consumes about 80% in the form of charge chrome or high-carbon ferrochrome . Increasing demand of chromium in steelmaking industries and the gradual depletion of high-grade chromite ores have led to the extraction of chromium from ...
Intermediate-Carbon Ferrochrome Intermediate-carbon ferrochrome is a product of further refining of charge chrome. In essence, the silicon in the product is reduced to below 0.3%, and the C is reduced to less than 1.5%, for the lowest intermediate grade. This alloy is chiefly used as a trimming addition in certain stainless steel grades, in tool
Jul 10, 2018· The vast majority of Fe-Cr produced is the 'charge chrome'. It has a lower Cr to C ratio and is most commonly produced for use in stainless steel production. The second largest produced Fe-Cr ferro-alloy is the 'high carbon Fe-Cr (HC Fe-Cr) which has a higher content of Cr and is being produced from higher grade chromite ore.
stainless steelmaking, stainless steel process control and charge chrome refining. 1 INTRODUCTION In this document the process for refining charge chrome with the objective of making MC FeCr and some other refined charge chrome products is described. Such a process has been operated by Samancor Chrome in Witbank since 1986 .
Feb 19, 2016· South African charge chrome prices in Asia fell while Indian/Omani ferrochrome prices held stable this week, Platts assessments showed.
Ferrochrome is divided into high-carbon ferrochrome according to different carbon content, including charging grade ferrochrome (C≦10%), medium carbon ferrochrome (C≦4.0%), low-carbon ferrochrome (C≦0.5%), and micro-carbon Ferrochrome (C≦0.15%), etc. Also commonly used are silicon-chromium alloys and ferrochromium nitrides.
consumption, slag properties, and alloy grade. Figure 1 indicates the theoretical minimum amount of energy and reductants required for ferrochrome (FeCr) production utilizing either AC or DC furnaces for various raw material inputs. Influence of charge material on power consumption The type and combination of charge materials
Medium Carbon Ferrochrome Medium carbon ferrochrome is producedby further refining of charge chrome. The silicon in the product is reduced to below 0.3 percent, and carbon is reduced to less than 1.5 percent for the lowest intermediate grade. The process takes place in a convertor where the liquid charge chrome is bottom blown

Aug 30, 2019· South Africa, the previous ferrochrome hub before China took the lead, has supplied the clear majority of third-party ores to growing ferrochrome capacity in Asia, which has taken advantage of lower cost (yet lower grade) ores from the African country. South Africa's own ferrochrome industry, meanwhile, has stagnated and faces ongoing challenges.
Feb 19, 2016· Japan's spot import price of 60%-65% grade high-carbon ferrochrome rose to 64-65 cents/lb CIF Japan Friday, compared to 62-64 cents/lb CIF Japan a week ago. One Indian producer said 65 cents/lb CIF Japan was acceptable, but he has not offered to Japanese buyers.
