  • Publication number: 20260185173
    Abstract: A molten iron dephosphorization method uses a top and bottom blown converter charged with molten iron and slag, supplies the oxygen-containing gas from an inlet of a blowing main hole, and supplies a control gas from an opening toward an axial center of the blowing main hole through a control gas supply passage. A slag top-surface position measurement step includes continuously or intermittently measuring an arbitrary position in a top surface of the slag. A slag top-surface difference calculation step includes calculating a slag thickness that is a difference between the measured top-surface positions of the molten iron and the slag. A jetting condition adjustment step includes, using the obtained slag thickness, adjusting a jetting condition of the oxygen-containing gas jetted from the top-blowing lance into an appropriate range. The top-blown jetting condition is adjusted by comparing the slag thickness and the depth of a surface depression.

  • Patent number: 12584187
    Abstract: A method removes phosphorus from a phosphorus-containing substance. In the method, the phosphorus-containing substance that is used as a raw material for metal smelting or refining is reacted with a nitrogen-containing gas so that phosphorus in the phosphorus-containing substance is removed through nitriding. Prior to a treatment of a nitriding removal of phosphorus from the phosphorus-containing substance, a treatment is performed in which the phosphorus-containing substance is heated to an unmolten state temperature range so as to react with a reducing agent, thereby reducing at least a part of metal oxide in the phosphorus-containing substance.
