Abstract
PURPOSE:To control cooling in such a way as to avoid inducing martensite transformation by making the flow of cooling water zero only in the period when the ingot part cast just before the stoppage is located in each unit zone of a secondary cooling zone in performing continuous casting after temporary operation stoppage. CONSTITUTION:While the ingot part 1B cast just prior to stoppage of casting is located in the 1st unit zone 6Iof the secondary cooling zone, the cooling water of the 1st unit zone 6Iis closed to make the flow of the cooling water zero, and the cooling water is supplied to other unit zones 6II-6IV. When the part 1B goes across the 1st zone 6Iand the 2nd zone 6II, the cooling water of the zone 6II is also interrupted. Further when it passes by the zone 6Icompletely, and is located in the 2nd zone 6II and the 3rd zone 6III, the supply of the water to the zone 6Iis resumed and the cooling water of the zone 6III is interrupted. Thereafter, the cooling water of the unit zones where there is the part 1B is interrupted successively. The part 1B is in about a 5m range in the drawing direction.
