我們用于建筑行業(yè)的材料也是越來越多了，目前新型的建筑體系中鋼結構得到廣泛的應用。而西寧鋼結構廠房的主要構件是焊接H型鋼柱、梁、撐。這些構件在制作過程中都存在焊接變形問題，如果焊接變形不予以矯正，則不僅影響結構整體安裝，還會降低工程的可靠性。那么關于這種鋼結構的變形矯正方法都有哪些呢，并且現(xiàn)在施工中大都采用哪種矯正方法，下面這篇文章為大家詳細講解，大家一起來了解一下吧。
We are also using more and more materials in the construction industry, and steel structures are currently widely used in new building systems. The main components of the Xining steel structure factory building are welded H-shaped steel columns, beams, and braces. These components all have welding deformation issues during the production process. If the welding deformation is not corrected, it not only affects the overall installation of the structure, but also reduces the reliability of the project. So what are the deformation correction methods for this type of steel structure, and which correction methods are mostly used in construction now? The following article will explain in detail for everyone to learn about together.
在生產過程中普遍應用的矯正方法，主要有機械矯正、火焰矯正和綜合矯正。但火焰矯正是一門較難操作的工作，方法掌握、溫度控制不當還會造成構件新的更大變形。因此，火焰矯正要有豐富的實踐經驗。本文對鋼結構焊接變形的種類、矯正方法作了一個粗略的分析。
The commonly used correction methods in the production process mainly include mechanical correction, flame correction, and comprehensive correction. But flame correction is a difficult task to operate, and improper control of methods and temperature can also cause new and greater deformation of components. Therefore, flame correction requires rich practical experience. This article provides a rough analysis of the types and correction methods of welding deformation in steel structures.

鋼結構的主要構件是焊接H型鋼柱、梁、撐。焊接變形經常采用以下三種火焰矯正方法：
The main components of steel structures are welded H-shaped steel columns, beams, and braces. The following three flame correction methods are often used for welding deformation:
（1）線狀加熱法；
(1) Linear heating method;
（2）點狀加熱法；
(2) Point heating method;
（3）三角形加熱法。
(3) Triangle heating method.
下面介紹解決不同部位的施工方法。
Here are the construction methods for solving different parts.
以下為火焰矯正時的加熱溫度（材質為低碳鋼）
The following is the heating temperature for flame correction (made of low-carbon steel)
低溫矯正（500度～600度）：冷卻方式：水
Low temperature correction (500 ° C to 600 ° C): Cooling method: water
中溫矯正（600度～700度）：冷卻方式：空氣和水
Medium temperature correction (600 ° C to 700 ° C): Cooling method: air and water
高溫矯正（700度～800度）：冷卻方式：空氣
High temperature correction (700 ° C to 800 ° C): Cooling method: Air
綜合文中講解，大家可以大體了解到這種鋼結構材料在發(fā)生變形時的矯正方法都有哪些，并且，火焰矯正時加熱溫度不宜過高，過高會引起金屬變脆、影響沖擊韌性。16Mn在高溫矯正時不可用水冷卻，包括厚度或淬硬傾向較大的鋼材，希望文中介紹對大家有幫助作用。
Based on the comprehensive explanation in the article, everyone can have a general understanding of the correction methods for this type of steel structure material when it undergoes deformation. Moreover, the heating temperature during flame correction should not be too high, as excessive temperature can cause metal embrittlement and affect impact toughness. 16Mn cannot be cooled with water during high-temperature correction, including steel with a high thickness or hardening tendency. We hope that the introduction in this article will be helpful to everyone.
