Title:
管又は棒を製造する装置及び方法
Document Type and Number:
Japanese Patent JP2007533579
Kind Code:
A
Abstract:
A process for producing tubes or rods is provided. The process includes providing a settable liquid and producing a strand by drawing the liquid from a nozzle in a drawing direction. The result of this is that the settable liquid emerges through an annular gap formed by the nozzle with the desired production throughput at the temperature which is above the devitrification temperature. The settable liquid cools as it flows down an outer and/or an inner surface of a displacement body so that, by the end of the displacement body, the settable liquid has a sufficiently high viscosity to be drawn in stable form at the desired production throughout without flowing more quickly than the drawing rate as a result of its own weight.
