    • PROBLEM TO BE SOLVED: To solve a problem, in which the inner peripheral shape of a coil, especially in the sideway-placing state, is deformed, by devising an annealing separating-agent. SOLUTION: As the annealing separating-agent, used when a steel sheet coated with the annealing separating-agent is wound in the coil-state and annealed at the temperature of ≥900°C, the one having 20-60% volume-shrinking ratio, is used. In this way, as the result for ensuring the surface pressure between the steel sheets after annealing, the deformation of the coil is prevented by keeping the frictional force between the steel sheets. Further, as the annealing separating-agent, magnesia is used as the main-material. COPYRIGHT: (C)2011,JPO&INPIT
