Summary

The influences of water temperature and roll speed on the cooling rate in thickness direction of ultra heavy plate are experimentally investigated in the present work. The results indicate that the water temperature and roll speed have influences on total heat transfer coefficient and heat transfer type near surface of plate, and affect the cooling rate in thickness direction by changing temperature gradient distribution. The cooling rate in thickness direction decreases as the water temperature and roll speed increase, and the decreasing range of cooling rate has relations with cooling region, cooling intensity, quenching time, and thermal conductivity of plate.
