Resumo
This paper presents a theoretical, experimental, and practical study on the momentum balance equation, and the compensation factor “K” term, which is responsible to measure the lost energy of the oxygen jet going out nozzle until metallic bath. The complete domain about this factor and their correct application promote reductions process times and productivity gains, but it has not been a target of study by researchers in this area. Based on the study theoretical and experimental about momentum balance equation evolution the new equation proposed fixed a convergence problem existing in the last equation found in the literature. Three industrial application proposal of the equation was applied to the 340t converter. Effectiveness comparative of the blow profile between the new equations x Masazumi was made and the new equation got 23% of the effectiveness in jet penetration evaluation. The proposal to Slagsplashing profile can be calculate due to the equation convergence. This practice allows the preliminary analysis can be done before the application in the process converter. Similarly, the Burn bottom profile was proposed. The preliminary analysis will allow the practice to be evaluated and made safely, reducing the risk of accidents. The trial results show the importance of the increase the process parameters in the cold model trial thus representing the industrial process correctly. The values of the compensation factor “K” were obtained for different nozzles and conditions and can be applied in mathematical models.
