冷弯是济南C型钢加工中的重要工序。虽然说冷弯后会有一个矫正过程，但经过一段时间后，变形还是很严重的，可见C型钢的残余应力很大。到目前为止，人们在选择型钢时，仍然需要注意其质量，以减少选择劣质钢的可能性。

Cold bending is an important process in the processing of Jinan C-beam. Although there will be a correction process after cold bending, the deformation is still very serious after a period of time. It can be seen that the residual stress of C-beam is very large. So far, people still need to pay attention to its quality when selecting profile steel to reduce the possibility of selecting inferior steel.

在评价C型钢产品的优劣时，首先要从表面质量入手，优良型钢的表面是镜面，没有凹凸不平的表面和颗粒。出现这种情况，说明所用材料中杂质较多，直接影响型钢的质量，此类产品会造成各种应用故障，增加人们的生产成本。

When evaluating the advantages and disadvantages of C-shaped steel products, the first step is to start with the surface quality. The surface of the excellent section steel is a mirror, without uneven surface and particles. This situation indicates that there are many impurities in the materials used, which directly affect the quality of the section steel. Such products will cause various application failures and increase people's production costs.

二是考虑型钢的厚度，人们在选择C型钢时，需要根据实际需要来选择，因为型钢的厚度直接影响其承载强度。如果大型建筑物需要具有优良承载能力的型钢，则必须选择厚壁钢。如果选择厚壁薄的碳钢，则根本无法承受相应的重量，从而增加了发生事故的概率。

The second is to consider the thickness of the section steel. When selecting the C-section steel, people need to select it according to the actual needs, because the thickness of the section steel directly affects its bearing strength. If large buildings need section steel with excellent bearing capacity, thick-walled steel must be selected. If thick and thin carbon steel is selected, it cannot bear the corresponding weight at all, thus increasing the probability of accidents.

选择型钢时除了要注意细节外，一般情况下，人们对型钢进行淬火时需要了解内部不同的材料，然后掌握相应的淬火温度。温度对整体淬火效果影响很大，如果温度没有达到理想状态，将加工好的型钢直接放入冷却液中，内部组织变化不大，直接浪费成本淬火。

In addition to paying attention to the details when selecting the section steel, generally, people need to know the different materials inside and then master the corresponding quenching temperature when quenching the section steel. Temperature has a great impact on the overall quenching effect. If the temperature does not reach the ideal state, the processed section steel will be directly put into the cooling liquid, and the internal structure will not change much, which will directly waste the cost of quenching.

另外，不同型钢的淬火温度不同，需要详细了解相关资料，才能保证温度达到理想状态。当沉浸在冷却液中时，要毫不犹豫地直接浸入，这样可以使整个型钢的冷却效果保持恒定。更多相关内容就来我们网站http://www.jnhscg.com咨询吧！

In addition, the quenching temperature of different section steels is different, so it is necessary to know relevant information in detail to ensure that the temperature reaches the ideal state. When immersed in the coolant, it should be immersed directly without hesitation, so that the cooling effect of the whole section steel can be kept constant.
