【考案の詳細な説明】 本考案は、つば付きの圧延ロールを設けてなる鋼材圧延
装置に関するものである。[Detailed Description of the Invention] The present invention relates to a steel material rolling apparatus provided with a flanged rolling roll.

この種の装置として例えば熱間圧延設備にふする幅調整
用又は幅大圧下用の籾圧延装置があるが、と力らの幅圧
延の際、圧下量が大きい程、圧延後の板製品はそのエツ
ジ部に線状疵又はラミネーション等が多発し、品質、歩
留り共に低下する。As an example of this type of equipment, there is a paddy rolling equipment for width adjustment or large width reduction, which is similar to hot rolling equipment, but during width rolling, the larger the amount of reduction, the greater the plate product after rolling. Linear flaws or laminations occur frequently at the edges, resulting in a decline in both quality and yield.

この主な原因は、前記幅圧延ロールによる幅圧延の際に
発生するドツグボーン形状を該つばにより抑制するため
、鋼材側端肩部の***部とつばとの圧接により焼付きが
発生したり、つばの回転方向に片寄って、重なり部分が
生じたりすることが掲げられる。The main reason for this is that the collar suppresses the dogbone shape that occurs during width rolling by the width rolling rolls, so seizure occurs due to pressure contact between the raised part of the shoulder on the side edge of the steel material and the collar. It is mentioned that the parts are shifted in the direction of rotation, resulting in overlapping parts.

そこでこの防止策として該つばに圧延油を塗布すること
が適切であるといえる。Therefore, it can be said that it is appropriate to apply rolling oil to the brim as a preventive measure.

本考案者等は圧延油の塗布方法としてスプレィ方式を採
用してみたがつばの圧延面にのみ圧延油を塗布すること
が困難であり主圧延面にも塗布されたり流下されること
が多いため主圧延面と鋼材端面とがスリップし、噛込み
不良、キャンバナ発生等の問題が発生し好オしぐなかっ
た。The inventors of the present invention tried using a spray method as a method of applying rolling oil, but it was difficult to apply rolling oil only to the rolled surface of the brim, and the oil was often applied to the main rolling surface as well, or it was washed down. The main rolling surface and the end surface of the steel material slipped, causing problems such as poor engagement and generation of camber, which did not go well.

本考案はこのような問題を有利に解決するものであり、
幅圧延ロールのつばのみに確実に圧延油を塗布するロー
ル塗油装置を設置した鋼材圧延装置を提供するものであ
る。The present invention advantageously solves these problems,
The present invention provides a steel rolling machine equipped with a roll oil application device that reliably applies rolling oil only to the brim of a width rolling roll.

This method reliably applies the required amount of oil only to a' and lb', and thereby, for example, in the case of the width rolling roll 1, without impairing the width rolling ability of the steel material S by the main rolling surface 1F,
There is no seizure due to pressure contact between the ribs la, lb and the raised portion S□yS2 of the shoulder portion on the side end of the steel material S due to rolling, and the raised portions S□, S2 are biased in the plane rotation direction of the ribs 1a, lb. It also reliably prevents overlapping.
