AI Technical Summary

Problems solved by technology

However, the carburizing process requires severe quenching from elevated treatment temperatures, which may distort the bend of the tube
The carburized layer was also found to be relatively brittle and to lose toughness at elevated temperatures due to exposure to hot rolled product

Embodiment Construction

[0043] Those of ordinary skill in the art, after considering the following description, will appreciate that the teachings of the present invention may be applied in laying heads of rolling mill coil forming apparatus, and more particularly in laying head elongated delivery path tubes or other methods for The equivalent elongated structure of a laying head. Aspects of the present invention facilitate extending the life of the laying path, enabling more tons of elongated material to be processed through the laying head prior to preventive maintenance replacement. For example, the processing speed of the laying head elongated material can be increased so that more tons of elongated material can be processed in a production shift without undue risk of laying path / tube failure.

Abstract

The invention relates to a rolling mill coil-forming laying head with path or pipe having laterally joined segmented construction. The rolling mill coil-forming apparatus includes a rotating quill that supports an elongated path hollow structure, such as a laying head pipe, for receiving elongated material after it has been rolled. The elongated structure is constructed of combinations of ferrous and non-ferrous dissimilar materials. Elongated path hollow structures are formed from adjoining, abutting segments, and can be constructed in any three dimensional compound curve shape that can replicate the smooth, continuous curve elongated material transport path of known laying pipes, or any other desired path. A pathway structure segment or plurality of segments may be constructed of a homogeneous material, or alternatively, different materials may be spliced or otherwise joined to form the composite, complete elongated path hollow structure. The adjoining segment portions may be nested within or circumscribe another pathway structure layer.
