Abstract

The invention provides a double-high-bar hole pattern rolling system suitable for multi-specification and multi-size production. The double-high-bar hole pattern rolling system is used for solving theproblem that in the prior art, multiple hole pattern systems are needed for production of double high bars of different specifications. The double-high-bar hole pattern rolling system sequentially comprises a roughing mill unit, an intermediate rolling unit, a pre-finishing mill unit and a finishing mill unit in the rolling direction; the roughing mill unit is of a flat-roller hole-free pattern rolling structure; the intermediate rolling unit comprises a hole-free pattern rolling structure and a hole pattern rolling structure, and the bar is sequentially subjected to hole-free pattern rollingand hole pattern rolling in the intermediate rolling unit; the pre-finishing mill unit adopts the same hole pattern rolling structure; and the finishing mill unit adopts the same hole pattern rollingstructure, more than one rack is arranged in the finishing mill unit, and the roll gap of each rack in the finishing mill unit is adjustable. The double-high-bar hole pattern rolling system can adaptto a wider size rolling range, the spare amount of dies such as rollers, roll collars and guides can be greatly reduced, and the capital occupation of enterprises is reduced.

Description

Technical field [0001] The invention relates to steel rolling process design, in particular to a double-high-bar rolling pass system suitable for production of multiple specifications and sizes. Background technique [0002] At present, both domestically and internationally, the double-high-bar rolling pass system adopts multiple pass design, and the production of different specifications of steel adopts different pass systems. [0003] On the one hand, the existing technology will greatly increase the spare capacity of molds such as rolls and guides, which will bring huge capital occupation pressure to enterprises; on the other hand, when changing specifications, it will increase the number of replacements of movement, roll rings and guides. It is not conducive to production organization, reduces production efficiency, and increases enterprise production costs. Summary of the invention [0004] In view of the above-mentioned shortcomings of the prior art, the purpose of the presen...
