| Abstract: | The production process for economically smelting molten phosphorus-containing weathering steel by low slag method without adding the lime is successfully developed according to the characteristics of the weathering steel.And also these effects of the above-mentioned smelting process on the tap-to-tap cycle,content of phosphorus in molten steel at the end point of blowing,oxygen consumption,consumption of the fluxes and blowing loss of molten steel are analyzed.The actual operations show that the oxygen-blowing time is shortened by 1.14 min per heat when the process is applied by the converter and further more the production capacity is increased,production cost is reduced and economic benefits are achieved. |
