| Abstract: | To analyze the microstructure,inclusion and gas element content of ER70S-6 wire rod produced by Tangsteel.Problems existing in original production process were found out.Process improvement measures were put forth.Si-Al-Ba compound deoxidizer was adopted to deoxidize,low carbon Mn-Fe alloy was replaced by low carbon and low phosphorous Si-Mn alloy.To control composition precisely and avoid LF furnace adjusting composition in large scope,molten steel cleanliness was improved.w(S) was controlled from 0.010% t... |
