Abstract

1. 청구범위에 기재된 발명이 속한 기술분야1. TECHNICAL FIELD OF THE INVENTION

본 발명은 서로 이웃해 있는 압연기에 있어서 압연롤의 축심간의 거리를 롤 직경의 1.2배 이하로 설정한 압연장치를 사용함으로써 조열을 통과해서 소요 단면치수로 압연된 피압연재료를 유지가이드를 설치하지 않고 연신압연하는 가이드레스압연방법에 관한 것이다.The present invention does not provide a holding guide for the rolled material rolled to a required cross-sectional dimension by passing through heat by using a rolling apparatus in which the distance between the shaft centers of the rolling rolls is set to 1.2 times or less of the roll diameter in the rolling mills adjacent to each other. It relates to a guideless rolling method of stretching without stretching.

2. 발명이 해결하려고 하는 기술적 과제2. The technical problem to be solved by the invention

전기한 압연기에 부설된 유지가이드는 압연기에 설치된 압하장치에 의해 압연롤의 간격조정을 행한 경우에는 이것에 따라서 적당한 위치로의 조정이 필요하게 되며, 작업명령의 변경등에 따른 조정에 필요한 시간이 길어진다는 결점이 있었다. 또한, 유지가이드의 안내불량은 압연제품의 불량으로 이어지기 때문에 베어링의 유지보수와 롤러의 표면결함점검, 회전상화의 점검등을 빈번하게 행해야만 한다. 또한, 각 압연기사이에 유지가이드를 설치하므로 구조가 복잡하게 됨과 동시에 설비비가 높아지는 난점도 지적된다.The retaining guides attached to the above-mentioned rolling mills need to be adjusted to the appropriate positions according to this when the rolling rolls are adjusted by the rolling device installed in the rolling mills. There was a flaw. In addition, the poor guide of the retaining guide leads to the failure of the rolled product, so the maintenance of the bearing, the inspection of the surface defect of the roller, the inspection of the rotational flaw and the like must be frequently performed. In addition, since the maintenance guide is provided between the rolling mills, it is pointed out that the structure becomes complicated and the equipment cost increases.

3. 발명의 해결방법의 요지3. Summary of Solution to Invention

이웃해 있는 압연롤의 회전축심이 90°의 각도로 경사지게 차례로 배치된 2대의 압연기를 갖추며, 양 압연기에 있어서 압연롤의 축심간 거리를 롤직경의 1.2배 이하로 설정한 압연장치를 사용해서, 피압연재료의 패스라인에 따라서 전기한 압연장치를 소정간격으로 여러개 배치하고, 전기한 피압연재료를 전기한 압연장치에 통과시킴으로써 그 재료를 연신 압연하도록 한 것을 특징으로 하는 것을 특징으로 한다.The rolling mills of two adjacent rolling mills are arranged with the rolling centers inclined at an angle of 90 DEG in order, and using a rolling apparatus in which the distance between the centers of the rolling rolls is set to 1.2 times or less of the roll diameter. A plurality of rolling devices described above are arranged at predetermined intervals in accordance with the pass line of the rolling material, and the rolled material is passed through the rolling device described above to extend and roll the material.
