Japanese economic industry
the fourth quarter of Japan's crude steel output will benefit from the strong demand of the domestic automotive industry, industrial and construction machinery industry, and is expected to achieve year-on-year growth.
What are the main sources of non-metallic inclusions in steel?
endogenous inclusions. It refers to the oxide formed by oxidation of elements during smelting, the deoxidation product formed during deoxidation, and the compound which is not melted in steel due to temperature drop and composition segregation during solidification.
How to deal with molten steel under the tapping process?
How to ensure the molten steel composition during the tapping process after the end point?
Is it correct to add more deoxidizer to molten steel, and the less oxygen in the steel must be? why?
Why is [Si] commonly used in blast furnace production to indicate furnace temperature?
Whether Si is reduced from liquid or gaseous, high temperatures are required. The higher the temperature of the hearth, the more Si is reduced into pig iron.
