description PROBLEM TO BE SOLVED: To provide a link type dummy bar and a continuous casting method. SOLUTION: The dummy bar 11 is formed by connecting an exclusive use body 12 and a common use body 13, which are arranged in the casting direction, by means of a connecting portion 14. The connecting portion 14 is configured such that three base blocks 14c having respective end faces connected to each other in the casting direction are arranged between two links 14a, 14b, and are connected by a connecting component 14d. The connecting component 14d is configured such that the exclusive use body 12 and one link 14a, and the common use body 13 and the other link 14b are connected by means of connecting pins 14da to 14dc by penetrating them in the width direction of a cast slab, and the links 14a, 14b and the base blocks 14c are fastened by fastening pins 14de via one leaf spring 14dd arranged in the casting direction across the upper sides of the links 14a, 14b and the base block 14c. The casting work is carried out by setting the length from the end surface of the exclusive use body 12 on the upstream side in the casting direction to the connecting pins 14dc to be 1.40 to 3.0 m. By the present invention, the variation of the level of the molten metal in a casting mold in the early stage of the casting work can be suppressed, and the surface quality of the cast slab can be improved, and the casting work can be stabilized.
