For the defects of numbness points and surface oxidation during the continuous annealing stage,combined with the on-site hydrating system and production parameters,this article is optimized by optimizing the RTF segment and SF segment dew point Color defects.Mainly collecting on-site data,obtaining steel parameters,production process parameters,and moisturizing system nozzles.Calculate the Moore concentration of different steel types and different elements based on steel parameters,and calculate the concentration of surface dissolving oxygen according to the production process parameters and corresponding corresponding to the concentration of oxygen oxygen and corresponding correspondingly The critical Moore concentration of the element.By establishing the relationship between the opening of the nozzle of the moisture and the dew point temperature in the furnace,the nozzle opening degree is adjusted to complete the optimization of the dew point temperature.After the model is invested,the surface hemp is shallower,and the qualification rate of steel products has increased significantly.
