摘要
PROBLEM TO BE SOLVED: To provide a continuous casting method of a Cu-Zn-Si-based alloy, that allows an oscillation mark depth to be sufficiently reduced and, allows an ingot of superior surface quality to be produced as a result.;SOLUTION: The continuous casting method of Cu-Zn-Si-based alloy is provided, in which continuous casting is carried out by intermittently drawing out a rod-like or a tubular ingot consisting of Cu-Zn-Si-based alloy which has a Cu content of 69 mass% to 79 mass%, an Si content of 2.0 mass% or more and less than 4.0 mass%, and a cross-sectional area of 10,000 mm2 or less. In the continuous casting method of the Cu-Zn-Si-based alloy, an intermittent withdrawal cycle consists of: a withdrawal operation in which a maximum movement speed used in moving the ingot in a withdrawal direction is Dmax, and a movement speed toward the withdrawal direction is 0.1×Dmax or higher; and a stopping operation in which the movement speed toward the withdrawal direction is less than 0.1×Dmax. In the intermittent withdrawal cycle, a movement distance of the ingot in the withdrawal direction is 5 mm or more, and stopping operation time TS in one intermittent withdrawal cycle is three seconds or longer.;COPYRIGHT: (C)2014,JPO&INPIT
