解决型钢变形问题及其施工环境条件是怎样的呢？事实上，型钢铣削时间过长，容易变形。为了解决这个问题，先要控制长工件的振动，这一点尤为重要。可以采用压在铣床平台上加工的方式，又或者用两个平口钳夹住。

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.

同时，采用适当的长工件加工工艺，如两次或三次粗加工，选择合适的工具，尽量锋利，避免工件应力变形，粗加工产生较小热量，也可考虑磨床磨削。因此，为了解决型钢的变形问题，主要是要控制其变形量，另外还要考虑长工件振动的因素，然后选择合适的加工工艺。

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，我们还应该注意一个问题，即型钢在负温下应该直接逐一检查其外观和质量。就型钢表面而言，局部区域不应有裂纹和颈部收缩。在这种情况下，型钢的安装实际上是一个基本的保证。

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.

当温度低于-20℃时，我们实际上会直接禁止型钢进行一系列冷弯操作。如果型钢在冬季负温下焊接，此时一定要小心，尽量安排在室内。如果焊接必须在室外进行，还应注意环境温度不应低于-20℃，下雪天不应进行焊接。

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.

济南型钢在室外焊接时，还应时刻注意风力。当风力超过3级时，应直接设置防风措施。对于焊接后未冷却的接头，必须禁止接触冰雪。

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.

此外要注意型钢运输和加工时，必须注意防止碰撞或划伤，同时为了安全着想，操作人员需要提前做好准备工作，更多事项就来我们网站http://www.jnhxtcg.com咨询吧。

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://www.jnhxtcg.com Consult.
