| titleOfInvention | Tailings is utilized to assist method and the Semi-steel making method of steelmaking slagging in duplex technique |
| abstract | The invention discloses in a kind of duplex technique and utilize tailings to assist method and the Semi-steel making method of steelmaking slagging, described steel-making tailings mixes with containing Si slag making materials and obtains mixing slag charge by it; Described mixing slag charge, when going out half steel, joins in ladle with half steel stream, and bottom blowing stirring is to carry out molten in advance to the mixing slag charge in ladle simultaneously; Go out after half steel terminates, be blended in steel-making converter and carry out semi-steel making.Present method has carried out pre-slagging to converter steelmaking slag charge, avoids in Converter to add a large amount of various slag charges and to cause in stove liquid steel temperature fluctuation frequent, affects carrying out smoothly of slag making, stabilizes terminal point control.Present method steel-making tailings is originally as useless tailings, and cost taken by themselves is low, directly enters in molten metal, can improve recovery rate of iron and energy efficient, effectively reduce production cost after fusing through steel-making chemical reaction.Present method covers on fluid surface after adding material melting, solves tapping process and to smolder problem, protect environment and worker health. |
