Cold Rolled Steel Coil Manufacturers To Processing Of Phase Diagrams

China supply cold rolled steel coil manufacturers in the practice of hot-dip galvanizing production, the temperature value of each point in the zinc liquid is less than 522.50C, the generated zinc slag only has bottom slag and surface slag, no scum BBC selected data from The effect of Luo Qun and his team, the initial concentration of aluminum in the zinc pot is 0.14070, the initial concentration of iron is 0.0177070, so we only need to study the phase diagram of these values. The mathematical method is used to simplify the fitting requirements of the data in the phase diagram. We think that there is only one turning point of 522.50C:5600C in 4600C:522.50C. After the fitting result, the principle of discriminating the type of zinc slag at each node of the zinc pot is as follows:

1. If the temperature value corresponding to this point is less than 522.50C, the temperature value at this point is substituted into the equation to obtain the iron concentration value corresponding to the transition point;
2. Substituting the obtained iron concentration value on the corresponding turning point with the temperature value of this point into the equation to obtain the aluminum concentration value corresponding to the turning point;
3. If the corresponding temperature value is greater than 522.50C, the temperature value is substituted into the equation and the equation to obtain the iron concentration values ​​at the two corresponding transition points;
4. Comparing the aluminum concentration value at the point in the zinc liquid with the aluminum concentration value at the turning point 2, 3, such as the aluminum concentration value is larger than the aluminum iron concentration value at the turning point 2, and using the equation to obtain the iron solubility, If the value on the transition point 3 is larger than the value on the transition point 2, and the solubility of the iron is obtained by using the equation, such as smaller than the value on the transition point 3, the solubility of the iron is obtained by using the equation;
5. Compare the iron concentration value at this point with the solubility value of iron. If the solubility value is greater than the solubility value, the iron element will be separated. The type of the material separated at this temperature can be used to calculate the quality of the zinc slag.
