Embodiment

[0039] Embodiment: a kind of embedded type spinning pipe, as figure 1 As shown, it includes an outer tube 1, and the outer tube 1 is sequentially arranged as a straight line introduction section 1A, a curved deformation section 1B and a stable section 1C along its input end to the output end, and the straight line introduction section 1A, the curved deformation section 1B and the stable section 1C are integrally formed . The material of the outer pipe 1 is a thermally stable material commonly used in existing single-layer spinning pipes, such as 10CrMo918.

[0040] Such as figure 2 As shown, it also includes an inner pipe 2, the inner pipe 2 is a straight pipe made of wear-resistant material, and the wear-resistant material can be duplex stainless steel, high-speed steel, precipitation hardening stainless steel, high manganese steel, ductile iron, etc. The axial dimension of the inner tube is smaller than that of the outer tube, preferably 500-1000 mm; the inner tube 2 and...

Abstract

The invention discloses a material selection method for an embedded spinning tube and an internal tube material of the embedded spinning tube. The inner tube made, the inner tube is a straight tube, its axial dimension is smaller than the axial dimension of the outer tube, the inner tube is inserted into the outer tube from the straight lead-in section of the outer tube, and the two are fixed at the inlet end; The outer tube is made of heat stable material. The embedded spinneret of the present invention can apply the whole pipe made of high wear-resistant material to the traditional spinneret, solve the problem that the spinneret is easily worn locally, prolong the service life of the spinneret, and improve production quantity.

Description

technical field [0001] The invention relates to the technical field of spinning tubes, in particular to an embedded spinning tube and a method for selecting the inner tube specification of the embedded spinning tube. Background technique [0002] The laying head is the key equipment on the high-speed wire rod finishing mill production line, located between the water cooling section of the finishing mill's post-control cooling line and the loose coil conveyor. As one of the most important parts of the laying machine, the wire is changed from a linear motion to a spiral motion under the comprehensive action of the driving force, relative inertia force, friction force, and positive pressure caused by the pinch rod and the laying machine. , forming a stable coil with a diameter of about Ф1080mm, which is ejected from the spinning tube. [0003] The paper titled "Study and Improvement on the Spatial Curve of the Spinning Tube of High-speed Wire Laying Machine" published in the J...
