【考案の詳細な説明】
本考案は多段圧延機における通板ガイド、詳しくは、パ
スラインを挾んで上下一対対向配置される通板ガイドの
うち上部通板ガイドに関するものである。[Detailed Description of the Invention] The present invention relates to a threading guide in a multi-high rolling mill, and more specifically, to an upper threading guide among the threading guides arranged in a pair of upper and lower sides opposite to each other with a pass line in between.
知られるように、圧延機の前後面には圧延材を円滑に案

ールに対する圧延油を噴射供給せしめる所謂クーラント
油の供給へラダーを兼用させることが行なわれる。As is known, threading guides are arranged on the front and rear surfaces of a rolling mill to smoothly guide the rolled material, but due to the structure of a multi-high rolling mill, it is difficult to secure sufficient space in the rolling mill housing. Instead, the rudder is also used to supply so-called coolant oil, which injects and supplies rolling oil to the rolling rolls to the plate passing guide.
ところで一般にこの多段圧延機は単スタンド圧延機とし

面性状を低下せしめる原因となっていた。By the way, this multi-high rolling mill generally performs reciprocating (reparing) rolling as a single stand rolling mill.
Therefore, depending on the direction of rolling, the supply of coolant oil from the threading guide is repeatedly stopped so that coolant oil is supplied to the inlet side of the rolling mill depending on the direction of rolling. Even if the coolant oil remains in the piping to the upper threading guide or in the upper threading guide as a supply header, it may leak out and drip onto the rolled material, making it difficult to dispose of the wound coil. Furthermore, in the case of performing a post-treatment process such as annealing treatment, thermal decomposition of the coolant oil causes deterioration of its surface properties.

である。The present invention was developed in view of the above-mentioned points, and its purpose is to provide an upper plate passage guide that can prevent coolant oil from dripping when the supply of coolant oil is stopped. , a threading guide disposed on the front and rear surfaces of a multi-high rolling mill having a coolant oil supply passage for a plurality of rolling rolls therein, an oil drain groove that crosses the coolant oil supply passage and slopes forward; is cut into the bottom of the supply passage, and a side groove is provided along the side wall of the outermost supply passage so as to communicate with the oil drain groove.
以下図示の実施例にもとづいて本考案に係る通板ガイド
を説明する。The threading guide according to the present invention will be explained below based on the illustrated embodiment.

支承するバックアップロール５が配置されている。In the figure, 1 is a housing of a multi-high rolling mill, which includes a pair of work rolls 2, a first intermediate roll 3 that supports them, a second intermediate roll 4 that supports them, and finally a backup roll 5 that supports the roll group. is located.
６はその先端がワークロール２に隣接するように適宜の

で、パスラインを中心に上下対称位置に配置される。Reference numeral 6 denotes a sheet passing guide that is attached to the rolling mill housing 1 by appropriate means so that its tip is adjacent to the work roll 2, and is arranged vertically symmetrically with respect to the pass line.

３が開設されている。As shown in detail in FIGS. 2 to 4, the threading guide 6 is provided with a plurality of coolant oil supply passages 8 on a guide member 7 whose lower surface is a smooth threading surface, and crosses the supply passages. Oil drain grooves 9 inclined toward the work roll 2 side are carved at arbitrary intervals at the bottom of the supply passage 8.
Along the side wall 11 of the outermost supply passage 8' in the supply passage 8 provided in the sheet passing guide 6 so as to communicate with the
An open side groove 10 is provided at the front end of the plate passing guide 6, and a cover 12 is fixed with bolts or the like to the upper surface of the partition wall 7' provided on the guide member 7 so as to cover the entire supply passage 8. Connection hole 1 for supplying coolant oil to the rolling roll (not shown) is provided at the end of the work roll.
3 have been established.
上述のような構成を有する本考案に係る通板装置におい
て、圧延が図中右方向から左方向に向かって行なわれる
とき圧延ロールのクーラント油は供給管から接続孔１３
を通して供給され通板ガイド６、即ち、各供給通路８の
先端からワークロール２に噴射供給される。In the sheet passing device according to the present invention having the above-mentioned configuration, when rolling is performed from the right direction to the left direction in the figure, the coolant oil of the rolling rolls flows from the supply pipe to the connection hole 13.
The material is supplied through the sheet passing guide 6, that is, from the tip of each supply passage 8, and is injected and supplied to the work roll 2.
いま、圧延方向が切換えれらると、圧延材の出側に相当
する通板ガイド６に対するクーラント油の供給が遮断さ
れるが、供給管あるいは一通板ガイド６に設けられた供
給通路８内に残存するクーラント油は、各供給通路８を
流下してくると排油溝９に流入し、捕捉されてこの排油
溝９を通りさらに供給通路８′に設けた側溝１０を通り
、通板ガイド６の先端両側位置から排出されることにな
る。Now, when the rolling direction is switched, the supply of coolant oil to the plate passing guide 6 corresponding to the outlet side of the rolled material is cut off, but the coolant oil is not supplied to the supply pipe or the supply passage 8 provided in the single plate guide 6. When the remaining coolant oil flows down each supply passage 8, it flows into the oil drain groove 9, is captured, passes through this oil drain groove 9, and further passes through the side groove 10 provided in the supply passage 8', and then passes through the plate passing guide. 6 will be discharged from both sides of the tip.
従って、この排油溝９は通板ガイド６の可能な限り先端
に近づけて設けるのが好ましいものであり、排油溝の数
、巾、深さなど必要性に応じて決定されるべきである。Therefore, it is preferable to provide this oil drain groove 9 as close to the tip of the plate passing guide 6 as possible, and the number, width, and depth of the oil drain grooves should be determined according to necessity. .

効果は大なるものである。As is clear from the above explanation, by carving an oil drain groove across the coolant oil supply passage and further providing side grooves that communicate with the oil drain groove along both sides, this oil drain groove guides the sheet threading. Alternatively, since the coolant oil flowing out from the supply pipe is captured and discharged to the outside through the side groove, it is possible to effectively prevent excess coolant oil from dripping onto the rolled material. The material can be handled easily, and furthermore, the deterioration of surface properties caused by coolant oil in the annealing process can be prevented, and other effects are significant.
