Seamless pipe continuous casting

Seamless billet piercing process according to the different requirements and the production methods can be divided: there ingot, billet, rolling slab, billet and forging a hollow slab.

If you press the tube cross-sectional shape, then you can also be divided into: round, square, octagonal and square wave-shaped tube and so on. Seamless steel pipe processes for continuous casting: steel continuously through a water-cooled mold, after continuous cemented crust pulled from beneath the mold exit by water cooling, after all the casting solidification process into billets.

Now a large number of applications is seamless production round billet continuous casting and rolling. Only for medium-sized ingot cycle pipe mill. Using rotary piercing round billet push piercing and piercing pressure is often used billet. Continuous casting round billet production is seamless application of more blanks on the current international, which is also a measure of a country's steel production technology logo. Continuous casting round billet with finished product rate, low cost, low power consumption, stable organizational performance characteristics, the mainstream tube development. Forging stock is often used on special alloy steel and rolling method is difficult to obtain or economic uneconomical.

Centrifugal casting method is mainly used for high-alloy steels and difficult perforated metal.
