HOT-DIP GALVANIZING FACILITY AND CONTROLLING METHOD THEREOF

PROBLEM TO BE SOLVED: To provide a hot-dip galvanizing facility having a direct-fired alloying furnace, which responsively and stably controls a temperature of a metallic sheet, and inhibits a surface defect from occurring due to a poor degree of alloying. SOLUTION: The hot-dip galvanizing facility...

Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a hot-dip galvanizing facility having a direct-fired alloying furnace, which responsively and stably controls a temperature of a metallic sheet, and inhibits a surface defect from occurring due to a poor degree of alloying. SOLUTION: The hot-dip galvanizing facility has a structure in which a flame heating burner 52 is arranged in a lower part of a direct-fired alloying furnace 5, and a distance between the metallic sheet (S) and the burner can be changed.
