解決型鋼變形問題及其施工環(huán)境條件是怎樣的呢？事實(shí)上，型鋼銑削時(shí)間過長，容易變形。為了解決這個(gè)問題，先要控制長工件的振動(dòng)，這一點(diǎn)尤為重要。可以采用壓在銑床平臺(tái)上加工的方式，又或者用兩個(gè)平口鉗夾住。

What is the solution to the deformation of section steel and its construction environmental conditions? In fact, the milling time of profile steel is too long and it is easy to deform. In order to solve this problem, it is particularly important to control the vibration of long workpiece. It can be processed by pressing on the platform of the milling machine, or clamped with two flat jaw pliers.

同時(shí)，采用適當(dāng)?shù)拈L工件加工工藝，如兩次或三次粗加工，選擇合適的工具，盡量鋒利，避免工件應(yīng)力變形，粗加工產(chǎn)生較小熱量，也可考慮磨床磨削。因此，為了解決型鋼的變形問題，主要是要控制其變形量，另外還要考慮長工件振動(dòng)的因素，然后選擇合適的加工工藝。

At the same time, adopt appropriate long workpiece processing technology, such as two or three rough machining, select appropriate tools and be as sharp as possible to avoid workpiece stress deformation, rough machining will produce less heat, and grinder grinding can also be considered. Therefore, in order to solve the deformation problem of profile steel, the main thing is to control its deformation, in addition to considering the vibration of long workpiece, and then choose the appropriate processing technology.

此外，我們還應(yīng)該注意一個(gè)問題，即型鋼在負(fù)溫下應(yīng)該直接逐一檢查其外觀和質(zhì)量。就型鋼表面而言，局部區(qū)域不應(yīng)有裂紋和頸部收縮。在這種情況下，型鋼的安裝實(shí)際上是一個(gè)基本的保證。

In addition, we should also pay attention to a problem, that is, the appearance and quality of section steel should be directly checked one by one under negative temperature. As far as the profile steel surface is concerned, there should be no cracks and neck shrinkage in local areas. In this case, the installation of section steel is actually a basic guarantee.

當(dāng)溫度低于-20℃時(shí)，我們實(shí)際上會(huì)直接禁止型鋼進(jìn)行一系列冷彎操作。如果型鋼在冬季負(fù)溫下焊接，此時(shí)一定要小心，盡量安排在室內(nèi)。如果焊接必須在室外進(jìn)行，還應(yīng)注意環(huán)境溫度不應(yīng)低于-20℃，下雪天不應(yīng)進(jìn)行焊接。

When the temperature is lower than -20 ℃, we will actually directly prohibit a series of cold bending operations of section steel. If the section steel is welded under negative temperature in winter, be careful and try to arrange it indoors. If welding must be carried out outdoors, it should also be noted that the ambient temperature should not be lower than -20 ℃, and welding should not be carried out in snowy days.

濟(jì)南型鋼在室外焊接時(shí)，還應(yīng)時(shí)刻注意風(fēng)力。當(dāng)風(fēng)力超過3級時(shí)，應(yīng)直接設(shè)置防風(fēng)措施。對于焊接后未冷卻的接頭，必須禁止接觸冰雪。

When Jinan section steel is welded outdoors, attention should also be paid to the wind at all times. When the wind force exceeds level 3, wind prevention measures shall be directly set. The joints that have not cooled after welding must not be exposed to ice and snow.

此外要注意型鋼運(yùn)輸和加工時(shí)，必須注意防止碰撞或劃傷，同時(shí)為了安全著想，操作人員需要提前做好準(zhǔn)備工作，更多事項(xiàng)就來我們網(wǎng)站http://m.qianhairuiben.com咨詢吧。

In addition, pay attention to prevent collision or scratch when transporting and processing section steel. At the same time, for the sake of safety, operators need to make preparations in advance. For more matters, please come to our website http://m.qianhairuiben.com Consult.
