本発明は形鋼圧延機に関し、剛性が高くそしてパスライ
ン変更及びパスシフトが容易に行なえる新規圧延機を提
供するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a shaped steel rolling mill, and provides a novel rolling mill that is highly rigid and allows for easy pass line changes and pass shifts.
周知のように圧延機では鋼材を噛み込むと圧延反力でハ
ウジング等が伸び、ロール間隙が変化する。即ち１．圧
延中のロール間隙Ｓは設定間隙をＳ。。As is well known, when a steel material is caught in a rolling mill, the housing and the like are elongated due to the rolling reaction force, and the gap between the rolls changes. Namely 1. The roll gap S during rolling is the set gap S. .

、圧延反力は最終的には圧延機スタンドで受けるので、
圧延機スタンドの変形、スタンドポストの伸びに対する
対策を別途考慮しなければ厚さ変化を完全に阻止するこ
とはできない。If the elongation of the housing etc. due to the rolling reaction force F is δ(F), then S = S. +δ(F). To deal with the change in the gap due to this rolling reaction force FK and the accompanying change in the thickness of the rolled material, a roll bending device applies a bending moment in the opposite direction to the bending moment generated by rolling to the rolls to reduce the gap between the rolls. It is conceivable to keep the thickness constant and eliminate thickness changes. However, since the rolling reaction force is ultimately received by the rolling mill stand,
Unless measures are taken to prevent deformation of the rolling mill stand and elongation of the stand post, thickness changes cannot be completely prevented.

ある。この結果、得られる形鋼製品の寸法にばらつきを
生じ、問題がある。In thin plate rolling, etc., a gauge meter method is used in which the elongation δ(F) of the housing etc. is predicted (calculated) and 80 is set so that the desired exit side plate thickness is obtained. However, although the elongation δ(F) of the housing, etc. is caused by the rolling reaction force, if we subdivide it, it is not due to the elongation of the stand post or the deformation of the roll (curving and flattening), etc., and the cause is also the structure of the stand. There are fixed types, such as, and variable types, such as the material of the rolled material and temperature, so it is difficult to accurately understand. In order to further improve controllability, it is necessary to increase the rigidity of each stand, roll, etc., but there are limits to this in terms of equipment. As a result, the dimensions of the obtained shaped steel products vary, which poses a problem.

らないという厄介さがある。Next, in universal rolling mills and caliber rolling mills that roll shaped steel, there is a pass shift that aligns the widthwise center of the steel material with the widthwise center of the rolling roll, and the heightwise center of the steel material and the center of the rolling gap between the rolling rolls. It is necessary to change the pass line to match. To align the center in the width direction, there is a method of moving the steel material using side guides, but this method has problems such as scratches on the steel material. In addition, there is a method for aligning the center in the height direction using a tilting cheeple, but in this method the centering is done by tilting the steel material from the horizontal, so the steel material enters the rolling mill diagonally. There are defects such as deviation of the center of the shaped steel. These problems can be solved by moving the rolling mill vertically and horizontally, but moving the entire mill, such as the rolling rolls and the housing that supports them, requires the cumbersome task of manipulating huge heavy objects. There is.
本発明は、上記の難点の全てを解決する新規な構造の形
鋼圧延機を提供しようとするものである。The present invention aims to provide a section steel rolling mill with a novel structure that solves all of the above-mentioned difficulties.
本発明では、圧延機のハウジングを従来のいわば一重式

をＦ、とすると
Ｆ ＝ Ｆ１＋ Ｆ。In the present invention, the housing of the rolling mill is changed from the conventional single-layer type to a double-layer type consisting of an outer fixed housing and an inner movable housing. A hydraulic cylinder is provided, and the inner housing is pressed by this hydraulic cylinder, and the rolling reaction force is supported by the outer housing. The total rolling reaction force is F, the pressing force by the hydraulic cylinder is Fl, and the force applied to the post of the inner stand. Let F be F = F1 + F.

側ハウジングポストにかかる力が小となる。例えば押圧

ングポストにがかる力Ｆ。Therefore, the force F received by the post of the conventional one-sided stand becomes the force F received by the inner one stand post in the present invention, and when receiving the same rolling reaction force, the force applied to the inner housing post is lower than that of the conventional one. becomes small. For example, if the pressing force F with the pressing device is F, = F, then the force F applied to the inner housing post.

点がある。It is also possible to set it to zero. Further, with such a structure, the inner housing can be made into a lightweight portion with low mechanical strength. Moreover, the elongation of the stand post due to the rolling reaction force F can be reduced to zero, and the elongation component of the stand post, which accounts for 20 to 50 inches of the elongation δ(F) of the housing, etc., can be removed, and the rigidity of the rolling mill can be increased accordingly. can be increased. In fact, the lighter the inner housing is, the easier it is to move, making it easier to shift passes and change pass lines when moving the rolling mill. Therefore, the pass line can be changed by moving the inner housing up and down using the suppression device for supporting the rolling reaction force, which has the advantage that no special device is required.

せ、パスシフトを行なう。For pass shifting, a cross beam extending perpendicular to the rolling direction is interposed between the upper and lower pressing devices and the inner housing, and the inner stand is supported by the upper and lower cross beams and moves in the direction perpendicular to the rolling direction. The pressing force of the hydraulic cylinder is applied to the upper and lower surfaces of the inner housing through the housing. A drive device such as a hydraulic cylinder is provided at one end of this cross beam, and this drive device is coupled to the inner housing, and the inner housing is moved by a predetermined distance in the lateral direction perpendicular to the rolling direction by operation of the drive device, resulting in a pass shift. Do the following.

、ミル剛性の改善を行なう。The spacing between the right boss) 2B and 2B is adjusted and fixed, making it possible to support rolls with different body lengths. It may not be a naive thing to say, but the inner housing tie rod 2C only receives the force that acts when the inner 1 housing moves, but it does not receive any abnormal force that acts during rolling or the vertical roll reaction force of universal rolling, which will be described later. . For these purposes, the abnormal force during rolling is caused to be absorbed by the outer housing by the coffin movement prevention wedge 17 of the inner stand, and the reaction force of one vertical roll is made to be absorbed by the outer housing. Note that 6 in Figure 4
0 is the key 200 guide member, which is attached to the two beams. Also, 31 is the load cell, 32 is the beam 2A and post 1
This is the nut that connects B. The rolling reaction force is a system of the roll chock 3', the rolling down device 5, and the beam 2A that pulls the post 1B, and the load cell 31 measures the reaction force and adjusts the pressing force of the inner cylinder 2 by the hydraulic cylinder 6.7. , improve mill rigidity.

I made it. As a result, the inner stand can be suppressed and controlled by the suppression device from the outer fixed stand to prevent the inner stand from deforming due to rolling reaction force and affecting the thickness of the rolled material. Great rigidity can be ensured for the rolling mill stand. In this case, the outer fixed stand is not directly involved in setting the spacing of the rolling rolls, so the strength limit
Deformations are allowed. Further, since the rolling reaction force is taken care of by the fixed outer stand, the weight of the movable inner housing can be reduced, and it is extremely easy to change the upper and lower pass lines by raising and lowering the hydraulic cylinder 6 that supports the movable inner housing. Furthermore, cross beams 8 and 9 are interposed between the hydraulic cylinder 6 and the movable inner housing in the lateral direction perpendicular to the rolling direction, and a movable inner housing 11111 is provided at one end of the cross beam to move the entire movable inner housing in the longitudinal direction of the cross beam. Since the housing moving device 11 is provided, a pass shift can be easily handled by horizontally moving the lightweight movable inner housing. Furthermore, by making it possible to adjust and fix the distance between the vertical posts of the movable inner housing, rolls with different body lengths can be used interchangeably, resulting in a flexible combination gin mill.
