如果型鋼出現尺寸超差問題的話，您需要及時根據問題的特征找出相應的原因，才能對應的做出控制方法，達到處理的目的。下面濟南型鋼廠家為您講解。

If the size of the section steel is out of tolerance, you need to find out the corresponding reasons according to the characteristics of the problem in time to make corresponding control methods and achieve the purpose of treatment. Next, Jinan section steel manufacturer will explain to you.

缺陷特征

Defect characteristics

濟南型鋼截面幾何尺寸不符合標準規定要求的統稱。當與標準尺寸相差過多時，則呈現畸形。這類缺陷名目繁多，大多以產生部位及超差程度加以命名。如不圓度超差、長度超差等。

The general term for the geometric dimensions of Jinan section steel that do not meet the requirements of the standard. If there is too much difference from the standard size, it will be deformed. There are many names of such defects, most of which are named by the location and out of tolerance. Such as out of roundness and out of tolerance length.

產生原因

Cause

孔型設計不合理；孔型磨損不均，新舊孔配合不當；軋機各部分（包括導衛裝置）安裝不良，安全臼破裂；軋機調整不當；鋼坯溫度不均，單根溫度不均產生局部規格不合，整根低溫鋼產生全長規格不合，偏大。

The pass design is unreasonable; Uneven wear of the hole pattern, improper matching of new and old holes; All parts of the rolling mill (including the guide device) are poorly installed, and the safety mortar is broken; Improper adjustment of rolling mill; Uneven billet temperature, uneven temperature of a single piece will result in partial non conformance, and the whole low temperature steel will result in non conformance of the whole length, which is too large.

控制方法

Control method

正確進行軋機各部件的安裝；完善孔型設計，加強軋機調整操作；注意孔型磨損情況，新換成品孔時，根據具體情況，考慮同時更換成品前孔等有關孔型；提高鋼坯加熱質量，達到鋼坯溫度均勻；有的異形材，由于矯直后截面形狀變化，可能影響某一尺寸不合規定，此時可重新矯直消除缺陷。

Correctly install all parts of the rolling mill; Perfect pass design and strengthen adjustment operation of rolling mill; Pay attention to the wear of the pass. When replacing the finished hole, consider replacing the front hole of the finished product and other relevant passes according to the specific situation; Improve the billet heating quality to achieve uniform billet temperature; For some profiled materials, due to the change of section shape after straightening, a certain dimension may be affected. At this time, they can be straightened again to eliminate defects.
