SELECTION AND DISCUSSION OF REDUCING AGENTS FOR FERROMANGANESE-SILICON SMELTING
The main reducing agent for ferromanganese-silicon smelting is coke,and there are only directional sugges-tions for the quality requirements of this part of coke,lacking specific quality standards.This article analyzes the chan-ges in the use of coke in ferromanganese-silicons and the development of the coke industry over the years.By compa-ring the chemical composition,crushing strength,wear resistance,reactivity,post reaction strength,and specific re-sistance of various types of coke,it is found that simply selecting reducing agents based on these indicator data cannot accurately determine the quality of coke used in ferromanganese-silicons.After comparative analysis,it is believed that the high-temperature specific resistance is the key to evaluating the coke used in the production of ferromanganese-sili-con.The coke used in the production of ferromanganese-silicon should be studied based on this indicator and provide an evaluation basis.
