COMBINED TREATMENT EQUIPMENT FOR HOT DIP GALVANIZING OF STEEL PLATE AND CONTINUOUS ANNEALING.

摘要

A hot dip galvanized steel plate manufacturing path (1A) that guides a steel plate (1) that has been annealed in a continuous annealing furnace (10) to hot dip galvanizing equipment (20) and a cold rolled steel plate manufacturing path (1B) wherein the steel plate (1) that has been annealed in the continuous annealing furnace (10) avoids the hot dip galvanizing equipment are provided. Also provided, on an outlet of the continuous annealing furnace (10), is a sealing device (50) for preventing penetration of air from the cold rolled steel plate path (1B) into the continuous annealing furnace (10).
