C型鋼切割效果及其應力問題的解決

來源:http://www.ebassfish.com/ 日期:2020-12-10 發布人:jiangucaigang
C型鋼的應用可以說是相當的廣泛,不僅可以作為鋼結構建筑中的檁條、墻梁;也可以自行組合成輕量型屋架、托架等建筑構件。不管是哪種用途,都會涉及到C型鋼的切割。由于不同的切割方法有著不同的切割效果,因此需要按照客戶的要求進行適當的選用。
The application of C-section steel can be said to be quite extensive. It can not only be used as purlin and wall beam in steel structure building, but also can be combined into lightweight roof truss, bracket and other building components. No matter what kind of use, it will involve the cutting of C-section steel. Due to different cutting methods have different cutting effect, it is necessary to select the appropriate one according to the requirements of customers.
一般情況下,C型鋼在鋼結構中應用的話,它的切割盡可能選擇在剪切機上或鋸床上進行,尤其是對于薄壁型鋼屋架。
Generally, if C-section steel is used in steel structure, its cutting should be carried out on shear machine or sawing machine as far as possible, especially for thin-walled steel roof truss.

之所以這么建議,是因為這里要去下料要準確,易電動鋸割法做為適合,不僅工效高,而且斷面光滑平整、質量好,切割誤差非常的小。
The reason for this proposal is that the blanking should be accurate, and it is suitable for the electric sawing method, which is not only highly efficient, but also has smooth and smooth section, good quality and very small cutting error.
C型鋼也可以采用氣割的方式,但為了提高氣割質量,盡量采用小口徑噴嘴,并在切割后用錘子輕輕敲打,使切口平整,滿足各種用途的要求。跟其他冷彎型鋼一樣,C型鋼生產過程中面臨的問題是內應力的問題,由于材料存在較大的內應力,一旦投入使用的話有可能會發生變形,從而影響其使用效果。
However, in order to improve the quality of gas cutting, a small diameter nozzle should be used as far as possible. After cutting, the hammer should be used to gently tap the cut to make the cut smooth and meet the requirements of various uses. Like other cold-formed steel, the problem of C-section steel in the production process is the problem of internal stress. Due to the large internal stress of the material, once put into use, it may deform, thus affecting its use effect.
C型鋼的應力沒有辦法避免,在冷彎C型鋼的開卷、滾剪、閉卷等工藝過程中,都會增加一定的內應力,主要的是通過機械強制變形導致冷彎C型鋼具有一定的應力。除此之外,冷彎C型鋼如果沒有噴涂底漆,那么除銹和鈍化工藝也將會使得它的內應力釋放出來,造成彎曲和扭變。
There is no way to avoid the stress of C-section steel. In the process of uncoiling, rolling shear and closing coil of cold-formed C-section steel, certain internal stress will be increased. The main reason is that the cold-formed C-section steel has certain stress through mechanical forced deformation. In addition, if the cold-formed C-section steel is not sprayed with primer, the rust removal and passivation process will also release its internal stress, resulting in bending and torsion.
在沒有辦法避免的情況下,只能通過合理的操作來減少應力的產生,作為生產廠家和用戶而言,也要關注這方面的問題,確保冷彎C型鋼能被廣泛的運用。
In the case of no way to avoid, only through reasonable operation to reduce the stress, as manufacturers and users, should also pay attention to this issue, to ensure that cold-formed C-beam can be widely used.
