The following is directed to a coil-forming laying head system, and particularly, a coil-forming laying head system including a laying pathway structure.
In a typical rod rolling mill, as depicted diagrammatically in
Over the last several decades, the delivery speeds of rod rolling mills have increased steadily. With the increased speed in delivery of the hot rolled product, the forces exerted on the laying pipe are also increased, causing internal pipe surfaces to undergo wear. Wear of the laying pipe can lead to a reduced ability to deliver a stable ring pattern to the conveyor 22, which can affect the cooling and ultimately the end properties of the product. Replacement of a laying pipe is a time consuming and costly issue for a mill. The combination of larger than desired laying head pipe internal diameter and reduced rolling speeds have been implemented in order to schedule preventive maintenance pipe replacement during scheduled maintenance “downtime”. Conventional and current laying head pipes must be replaced after processing quantities of elongated material of approximately 2,000 tons or less, depending on diameter, speed and product composition.
Moreover, the fabrication of a conventional laying pipe is not simple. First a mandrel, which is used in the forming and contouring of the laying pipe must first be sourced. The formation of a mandrel having the precise contours necessary to form the laying pipe is a time consuming and costly venture. When forming the laying pipe on the mandrel, the laying pipe is first heated to a temperature above 900° C., which is a temperature that allows for manageable plastic deformation of the pipe by workers. The heated pipe is typically handled by workers and taken to the mandrel, where it is forcefully bent by hand around the mandrel using various hand tools to give it the appropriate three-dimensional shape. The process of handling and forming of the laying pipe is time-consuming and potentially hazardous for workers.
The industry continues to demand improvements in laying pipes to reduce mill downtime and reduce potentially hazardous conditions for workers.

The laying head system 30 can have a quill 50 can be configured to rotate about an axis 113. More particularly, the quill 50 can have a generally horn shape that is adapted to rotate about the axis 113. The laying head system may also include a laying pathway structure 60 and a pipe path support 70, which may be coupled to the quill 50. The laying pathway structure 60 and the pipe path support 70 may be configured to rotate about the axis 113 with the quill 50 during operation. The laying pathway structure 60 can be coupled to a pipe support 70 that is in turn coupled coaxially to the quill 50, so that all three components rotate synchronously about the quill 50 rotational axis 113. The quill 50 rotational speed can be selected based upon, among other factors, the elongated material M structural dimensions and material properties, advancement speed S, desired coil diameter and number of tons of elongated material that can be processed by the laying head pipe without undue risk of excessive wear.
The laying pathway structure 60 can define a hollow elongated cavity adapted to transport the elongated material M through its interior cavity. Aspects of the present invention allow the laying pathway structure 60 to include a laying head pipe. In fact, the laying pathway structure 60 may occasionally be referred to herein as a laying head pipe. The laying pathway structure 60 can have a generally helical axial profile of increasing radius, with a first end 62 that that is aligned with the rotational axis of quill 50 and configured to receive the elongated material M, which may be a metal product, which can be formed into a helical formation of rings. The first end 62 can be part of a proximal portion of the laying pathway structure 60. The laying pathway structure 60 can further include a second end 64 that can be part of a terminal portion of the laying pathway structure 60 displaced radially and axially from the proximal portion. The second end 64 can be spaced radially outwardly from and generally tangential to the quill 50 rotational axis 113 and thus discharges the elongated material M generally tangentially to the periphery of the rotating quill 50.
As illustrated, as elongated material M can be discharged from the second end 64, and may be directed into a guide 80 having guide rim segments 82 into which are formed a guide channel 84 having a helical pitch profile. As the elongated material M is advanced through the guide 80 it may be conformed into a helical formation of rings. The elongated material M can be configured into a helical formation of rings as the elongated material M traverses through the guide 80 and guide channel 84. The guide 80 can be coupled to the pipe support 70 and configured to rotate coaxially with the quill 50. The guide channel 84 rotational speed is substantially the same as the advancement speed S of the elongated material M advancement speed S, such that there may be essential no linear motion speed between the guide channel 84 and elongated material M, which may facilitate less wear of the surfaces of the guide channel 84 that contact the elongated material M.
A stationary end ring 90 can have an inner diameter that is coaxial with the quill 50 rotational axis 113 and circumscribes the second end 64 of the laying pathway structure 60 as well as the guide 80. The end ring 90 can counteract a centrifugal force imparted on the elongated material M as it is discharged from the laying head pipe 60 by radially restraining the elongated material M within the inner diameter surface of the end ring 90.
