Rotative continuous caster, which was only one in service in Japan, was operated at Kciliin Works of Nippon Kokan K. K. from March 1974 to December 1977. In total, 1.5 millon tons of billets have been cast in the four years operation. During this period, various modifications of equipments and improvement of billet quality were carried out and contributed to the high productivity, over 40000 tons/month.
Advantages of RCC process over the conventional ingotmaking-billetting process are;
(1) Conditioning of billet is eliminated.
(2) Total yield through all the processes of pipemaking increases by approximately 17%.
(3) Energy saving of 3 × 105kcal/ton is achieved.
(4) Total processing time required is shortened by 80%.
