Billet cannot come out of mould tube on its own for the first time in casting. It needs to be pulled out using a dummy bar. Whenever there is a breakout, this dummy bar has to be inserted into the mould tube again to pull out the new billet. This is called re-stranding. There are two types of dummy bars. One is a flexible link type or chain type of dummy bar and the other one is the rigid dummy bar. With the rigid dummy bar, the re-stranding time is negligible. With a flexible dummy bar, re-stranding time is longer resulting in lowering the temperature of LM in the ladle that often demands re-furnace. Flexible dummy bars demand skilled labor as the head needs to be guided always. The rigid dummy bar is automatic, self-guided, safer, and faster. We offer it because it makes the caster more reliable and efficient. Others are not willing to offer as rigid dummy bar involves technology and higher cost to the manufacturer.
