COPPER MOULD TUBE & DUMMY BAR
COPPER MOULD TUBE & DUMMY BAR
Casting tube known as crystallizer is the heart of continuous casting. Most of billet quality depends on the quality of tube. Tubes work under serious high-temperature condition, the material must have basic fea-tures such as good thermal conductivity, high strength, wear-resistance and sufficient .
the dummy bar is used to tract and leads cooled and solidified strand and pulls it out by the withdrawal and straightening machine. In order to avoid the deformation of dummy bar body due to heating, it is equipped with a cooling water pipe inside the bar body. It has the fea-ture of smaller deformation, long service life, simple structure and in-stallation, easy operation and maintenance.
