Problems solved by technology

[0005] The reason is that there are two other possibilities for this problem: first, the factors considered are not comprehensive enough, such as the positional relationship between the individual bottom guns, the dissipation speed of the bottom blowing airflow

Abstract

The invention discloses a prediction method for the lowest mixing time of a ladle, which establishes a prediction formula for the mixing time based on the mixing time data tested by a hydraulic modeland the geometrical characteristics of the model to predict and estimate the lowest mixing time of the hydraulic model. The blending time prediction formula is applied to the actual ladle prediction by comparison. The invention provides a new formula for predicting the lowest mixing time of the ladle, which has high accuracy; Used in laboratory research or industrial technology to reduce duplication of effort in obtaining data. At the same time, the invention further deduces the factors influencing the lowest mixing time of the ladle, and determines the physical meaning of the formula.

Description

technical field [0001] The invention belongs to the technical field of metallurgy, and in particular relates to a method for predicting the minimum mixing time of a ladle. Background technique [0002] In the refining and soft blowing process of the ladle, the stirring efficiency of the bottom blowing and the minimum mixing time are unmeasurable and can only be estimated by experience. In order to study the influence of different bottom blowing models on the stirring efficiency, the researchers designed the corresponding cold model based on the similarity principle, and calculated the bottom gun stirring efficiency of the ladle through the research of the model. As the most important parameter to measure the mixing model, the minimum mixing time is the core to compare the advantages and disadvantages of different models. However, no matter whether the bottom blowing components use air bricks or bottom guns, there are many ways to arrange them. There is no certain standard f...
