Q345NH weather-resistant steel plate

When the composition of molten steel in Q345NH weather-resistant steel plate is dispersed, the slope of liquidus temperature dispersion curve is large, while the temperature dispersion curve of molten steel is steep and has a small slope, which is not conducive to the long-term growth of dendrites in one direction, and prevent the development of columnar crystal bands.

The carbon content of Q345NH weather-resistant steel plate is high, the thermal conductivity of steel is poor, the molten steel is poured into the mold cavity, the heat conduction process is slow, the temperature is not easy to uniform, so the temperature difference in the molten steel is large, the slope of the temperature distribution curve is large, and the curve shape becomes steeper.

In addition, because of the fast growth rate of wear-resistant flat crystals and the relatively fast growth rate of dendritic crystals in liquid, the simple and rough crystal structure is conducive to the composition of columnar crystals.
