Synopsis :
The world's first multipurpose continuous annealing line facility started operation in July 1980 at the cold rolling plant, Chiba Works, Kawasaki Steel Corporation (KSC) and achieved steel production of 15000t in September. Steels to be produced involves five types; high temper tinplate, low temper tinplate, non-oriented electrical steel, high-strength cold rolled sheet steel and ordinary cold rolled sheet steel. In order to produce these five steels a single continuous annealing line, several technical innovations have been achieved in the mechanical,electrical and instrumental fields such as steel strip cooling system by gas jeb as fast as 50Ž/s, intrafurnace tension control and steel strip temperature control. A unigue design and arrangement of cooling sections with multiple functions have also been developed by applying three modes of heat cycle. KSC has successfully eatablished the production system and operation technology for producing five types of high quality steel with high productivity at low cost.
