### Analyzing metal material cooling intensity: A method for obtaining heat transfer coefficients

**ABSTRACT**

In laminar cooling, the cooling intensity is directly impacted by the heat transfer coefficient and affects the microstructure of metal materials, which in turn affects product performance. In order to determine the laminar cooling heat transfer coefficient, this study suggests a certain approach. Using the nozzle as the center, the dispersal form of coefficient of heat transfer as piecewise function formed a straight line and half sine wave was determined. It lays out the steps to take in experimental data, operating parameters, and structural parameters to get function's characteristic parameters. Experimental results confirm the method's correctness, and the effect of metal-specific characteristics on the temperature field was studied. A solid theoretical foundation for the field production process was provided by the mutual verification of the experimental and computed outcomes.
