본 발명은 형강재 교정방법에 관한 것으로, 특히 H빔 형강재의 교정방식을 웨브 부위의 접촉방식이 아닌 플랜지 단부 부위의 접촉방식을 통해 교정이 이루어지도록 함으로써, 적은 압하력으로도 교정성이 향상되도록 한 형강재 교정방법에 관한 것이다.The present invention relates to a method for straightening the steel material, and in particular, the calibration method of the H-beam steel is made by the contact method of the flange end portion instead of the contact method of the web portion, thereby improving the correctability even with a small pressing force. To a method of straightening the shaped steel as much as possible.

일반적으로, 압연 H빔 형강재는 동일 수직면 내에 축심을 갖는 상,하 한 조로 이루어진 수평롤과 좌,우 한 조로 이루어진 수직롤로 구성된 압연기를 사용하여 열간압연에 의해 제조된다.In general, the rolled H-beam steel is manufactured by hot rolling using a rolling mill consisting of a horizontal roll composed of a pair of upper and lower pairs having an axis in the same vertical plane and a vertical roll composed of a pair of left and right pairs.

그 열간 압연된 H빔 형강재는 이후 냉각과정을 거치면서 휘거나 구부러져 직각도가 불량해지기 때문에 통상의 롤러 교정장치를 사용하여 교정하고 있는 실정이다.Since the hot rolled H-beam steel is then bent or bent during the cooling process, the squareness is deteriorated, so it is corrected using a conventional roller straightening device.

기존의 형강 교정방식은 도 1 및 도 2에 개략적으로 도시된 바와 같이, 상,하부에 각각 복수개 마련된 교정롤(20)(30)을 통과하면서 H빔 형강재(10)의 웨브(12)부위와 교정롤(20)(30)이 접촉되는 과정에서 발생되는 압하력에 의해 휘어진 부위가 교정되는 방식을 채택하고 있다.1 and 2, the conventional beam straightening method passes through the web 12 of the H beam shaped steel 10 while passing through a plurality of straightening rolls 20 and 30 provided in a plurality of upper and lower portions, respectively. It adopts a method in which the bent portion is corrected by the pressing force generated in the process of contact with the straightening rolls (20, 30).

And a plurality of upper and lower straightening rolls 20 and 30 for correcting by transmitting a pressing force to the flange 14 side of the H-beam steel 10 which is provided and transferred to the upper and lower portions of the 100, respectively. The upper and lower straightening rolls 20 and 30 are composed of stepped portions 22 and 32 provided to correspond to the flange 14 portions of the H beam shaped steel 10 described above.

더 상세히 설명하면, 그 상,하부 교정롤(20)(30)들은 기존의 것과 동일한 이 동방향을 가지며, 상부 교정롤(20)이 H빔 형강재(10)의 진입방향에 대해 축방향으로 좌,우 수평 이동되어 H빔 형강재(10)를 지지하고, 하부 교정롤(30)이 H빔 형강재(10)의 진입방향에 대해 좌,우 및 상,하 이동되어 실제로 H빔 형강재(10)측에 압하력을 제공하는 교정구조를 갖는다.In more detail, the upper and lower straightening rolls 20 and 30 have the same moving direction as the conventional one, and the upper straightening roll 20 is axially with respect to the entry direction of the H beam member 10. It is horizontally moved left and right to support the H beam member steel 10, and the lower straightening roll 30 is moved to the left, right and up and down with respect to the entry direction of the H beam member steel 10 is actually H beam member steel It has a correction structure for providing a pressing force on the (10) side.

앞서 설명한 상,하부 교정롤(20)(30)들의 이동에 의한 교정방식은 각각의 모터(25)(35)에 의해 상,하부 교정롤(20)(30)들이 이동되는 기존의 일반적인 교정기(100)에 설치된 것과 동일하므로, 이에 대한 자세한 설명은 생략하기로 한다.The above-described calibration method by moving the upper and lower calibration rolls 20 and 30 is a conventional general calibrator in which the upper and lower calibration rolls 20 and 30 are moved by respective motors 25 and 35. Since the same as that installed in 100, a detailed description thereof will be omitted.

그 단턱부(22)(32)는 상기한 H빔 형강재(10)의 플랜지(14)부위와 접촉되는 상,하부 교정롤(20)(30)의 좌,우 외측 부위에 형성된 것으로서, 그 구조는 웨브(12) 부위의 단부에 대해 수직으로 마련된 H빔 형강재(10)의 내측 플랜지(14) 부위와 면접촉되는 접촉면(22a)(32a)과, 그 접촉면(22a)(32a)의 단부에 단턱지게 형성되어 H빔 형강재(10)의 플랜지(14) 단부에 위치한 팁 부위에 접촉되는 압하면(22b)(32b)으로 구성된다.The stepped portions 22 and 32 are formed on the left and right outer portions of the upper and lower straightening rolls 20 and 30 in contact with the flange 14 portion of the H-beam steel 10 described above. The structure has contact surfaces 22a and 32a in surface contact with portions of the inner flange 14 of the H-beam steel 10 provided perpendicular to the end portions of the web 12 portions, and the contact surfaces 22a and 32a. It is formed in stepped end and consists of the pressing surface 22b, 32b which contacts the tip part located in the edge part of the flange 14 of the H-beam steel 10.

또, 그 접촉면(22a)(32a)은 H빔 형강재(10)의 플랜지(14) 단부와 면접촉되는 부위와의 마찰을 고려하여 라운드진 형상으로 형성되는 것이 바람직하다.In addition, the contact surfaces 22a and 32a are preferably formed in a rounded shape in consideration of friction between a portion of the H-beam shaped steel 10 that is in surface contact with the end portion of the flange 14.

그리고, 접촉면(22a)(32a)과 압하면(22b)(32b) 사이에는 요홈부(22c)(32c)가 내측으로 형성되어 H빔 형강재(10)의 접촉시 여유공간으로 작용하게 된다.In addition, grooves 22c and 32c are formed inwardly between the contact surfaces 22a and 32a and the lower surfaces 22b and 32b to act as a clearance when the H beam shaped steel 10 is in contact.

그 여유공간인 요홈부(22c)(32c)는 단턱부(22)(32)의 압하면(22b)(32b)과의 접촉시 H빔 형강재(10)의 퍼짐을 방지하고 H빔 형강재(10)의 플랜지(14) 끝단이 일부 수용될 경우 교정롤(20)(30)로부터 이탈되는 것을 방지하는 기능을 갖는 것이 다. The recessed portions 22c and 32c, which are free spaces thereof, prevent the H-beam shaped steel 10 from spreading upon contact with the pressing surfaces 22b and 32b of the stepped portions 22 and 32 and the H-beam shaped steel. If the end portion of the flange 14 of the (10) is accommodated in part is to have a function to prevent the departure from the calibration roll (20) (30).

이러한 구조를 갖는 본 발명의 작용은 다음과 같다.The operation of the present invention having such a structure is as follows.

본 발명은 교정기(100)의 일측으로부터 타측으로 일방향으로 이송되는 H빔 형강재(10)의 웨브(12) 부위와 상,하부 교정롤(20)(30)의 외주면이 서로 이격되도록 함과 아울러, H빔 형강재(10)의 플랜지(14) 내측면과 상,하 양단부에 상,하부 교정롤(20)(30)의 단턱부(22)(32)가 각각 면접촉되도록 접촉시키면서 교정하는 방법을 채택하게 된다.The present invention is to be spaced apart from each other and the outer peripheral surface of the web 12 and the upper and lower calibration rolls 20, 30 of the H-beam steel 10 is transferred in one direction from one side of the straightener 100 to the other side And the upper and lower straight ends of the flange 14 of the H beam shaped steel 10 and the upper and lower straightening rolls 20 and 30 of the stepped portions 22 and 32 are in contact with each other so as to be in surface contact. The method will be adopted.

이때, 단턱부(22)(32)의 압하면(22b)(32b)이 H빔 형강재(10)의 플랜지(14) 단부와 접촉되어 있으므로, H빔 형강재(10)의 웨브(12)부위는 도면에 도시된 바와 같이 상,하부 교정롤(20)(30)과 이격된 거리(ℓ)를 유지하게 되고, 그 갭(GAP)으로 인해 상호간의 접촉이 이루어지지 않아 응력 전달이 차단된다.At this time, since the pressing surfaces 22b and 32b of the stepped portions 22 and 32 are in contact with the ends of the flanges 14 of the H-beam steel 10, the web 12 of the H-beam steel 10 The part maintains the distance (l) spaced apart from the upper and lower straightening rolls 20 and 30, as shown in the drawing, the gap (GAP) is not in contact with each other due to the stress transmission is blocked. .

여기서 압하력은 하부 교정롤(30)에서 상승되는 이동력에 의해 H빔 형강재(10)의 플랜지(14) 단부에 주로 작용하고, H빔 형강재(10)의 플랜지(14) 내측면에 접촉되는 접촉면(22a)(32a)은 H빔 형강재(10)을 단순 지지하는 기능을 갖게 된다.Here, the reduction force mainly acts on the end portion of the flange 14 of the H beam member steel 10 by the moving force lifted from the lower straightening roll 30, and is applied to the inner surface of the flange 14 of the H beam member steel 10. The contact surfaces 22a and 32a to be in contact have the function of simply supporting the H beam shaped steel 10.

또한, 하부 교정롤(30)을 상측으로 무리하게 이동시켜 큰 압하력을 부여하지 않더라도 용이하게 H빔 형강재(10)의 교정이 이루어지게 되므로, 교정성이 향상되고 웨브(12)와 플랜지(14) 부위의 경계부위에 전달되는 응력을 최소화할 수 있게 된다.In addition, even if the lower straightening roll 30 is forcibly moved upward, even if it does not give a large reduction force, since the straightening of the H-beam shaped steel 10 is easily performed, the correctability is improved and the web 12 and the flange ( 14) It is possible to minimize the stress transmitted to the boundary of the site.

즉, 본 발명은 교정기(100)의 상,하부 교정롤(20)(30)이 H빔 형강재(10)의 웨브(12) 부위에 접촉되어 교정되는 것이 아니라, H빔 형강재(10)의 플랜지(14) 부 위에만 접촉되어 교정되므로 교정이 용이하며 특정부위에 과도한 응력 전달로 인한 크랙 발생을 억제할 수 있는 이점을 갖는다.That is, in the present invention, the upper and lower straightening rolls 20 and 30 of the straightener 100 are not corrected by being in contact with the web 12 portion of the H beam shaped steel 10, but the H beam shaped steel 10. Since only the flange 14 of the contact portion is in contact with the correction, it is easy to calibrate and has the advantage of suppressing the occurrence of cracks due to excessive stress transfer to a specific portion.

이상과 같이 설명한 본 발명은 교정기의 상,하부 교정롤을 H빔 형강재의 플랜지 부위에만 접촉시켜 교정할 수 있도록 한 것인 바, 이에 따르면 본 발명은 H빔 형강재의 웨브 부위가 아닌 플랜지 부위만을 상,하부 교정롤이 접촉되어 압하력을 전달하여 교정하도록 함으로써, 기존의 압하 교정방식보다 적은 힘의 압하력으로도 교정이 용이하게 이루어질 뿐만 아니라, 특정 부위인 웨브와 플랜지 부위의 경계부위측에 과도한 응력이 전달되는 것을 방지하여 크랙 발생을 억제시키는 유용한 효과를 갖는다.As described above, the present invention allows the upper and lower straightening rolls of the straightener to be contacted with only the flange portion of the H beam shaped steel, so that the present invention is corrected according to the present invention. The upper and lower straightening rolls are brought into contact with each other to transmit the reduction force, so that the correction can be easily performed even with a reduction force of less force than the conventional reduction method. It has a useful effect of preventing the transfer of excessive stress to the crack suppression.
