Latest Patents

Zhiwen Zhang holds a patent for a revolutionary method for preparing low-cost clean steel. This method involves several critical steps:

1. **Preliminary Desulfurization**: The process begins with the desulfurization of the iron melt during blast furnace tapping and iron folding, utilizing a desulfurizing ball to enhance efficacy.

2. **Dephosphorizing and Controlling Sulfur**: During converter steelmaking, the process ensures that phosphorus (P) remains less than or equal to 0.014% and sulfur (S) less than or equal to 0.004% during tapping.

3. **Rapid Dephosphorization**: The method further includes rapid dephosphorization by slag-forming while controlling the carbon (C) content between 0.02% to 0.10%.

4. **Purification During RH Refining**: Finally, the steel melt undergoes purification in the RH refining stage by adding a purifying ball when a specific vacuum degree is reached.

This innovative approach not only enhances the quality of steel produced but also optimizes production costs, providing a competitive edge in the steel market.
