摘要

In a continuous hot-dip metal coating process into which a heat-treating furnace, e.g. non-oxidizing type or Sendzimir type is included, surface flaws of traveling strip produced by deposits of metallic oxides on hearth rolls of said furnace can be prevented by cooling the hearth rolls, preferably at less than 200 DEG .
