C型钢厂家选用全套双槽模具的整个送料过程大大提高了出钢作用，数控切开机的工作效率也大大提高。C型钢切开后，裂纹沿钢材的切削刃向基部延伸，裂纹的宽度为从前端到基部。逐步减少，在边缘构成厚的、低塑性区域。从切削刃的安排结构类似于受热区影响区的结构变化特征，C型钢存在不同程度的压应力，这是滞后开裂的重要原因。

The whole feeding process of the full set of double-groove die selected by the C-shaped steel manufacturer has greatly improved the tapping effect, and the working efficiency of the CNC cutting machine has also been greatly improved. After the C-section steel is cut, the crack extends along the cutting edge of the steel to the base, and the width of the crack is from the front end to the base. Gradually reduce to form a thick and low plastic area at the edge. The arrangement of cutting edges is similar to the structural change characteristics of the affected zone of the heating zone. There are different degrees of compressive stress in C-shaped steel, which is an important reason for delayed cracking.

济南C型钢厂认为，为了避免因C型钢因几何形状不利而引起淬火裂纹，通常应从两方面采取措施，一方面是在设计及加工制造上排除所有不利的因素。比如说对一些厚薄不均匀的材料，因截面变化较大而可能存在危险断面的C型钢，在设计上应力求做到避免这些情况。

Jinan C-beam steel plant believes that in order to avoid quenching cracks caused by unfavorable geometric shape of C-beam, measures should be taken from two aspects. On the one hand, all unfavorable factors should be eliminated in design and manufacturing. For example, for some materials with uneven thickness, C-shaped steel with dangerous section may exist due to large changes in section, we should strive to avoid these situations in design.

还有一方面是通过改善热处理技术解决问题，比如在淬火加热前于截面变化急剧处涂以硼砂，或以铁丝、石棉及火泥填塞，以防局部过热及减小因尺寸不均匀而引起的温差；采用分级加热的方法，减小因温差过大而引起的内应力；在C型钢性能的前提下，尽可能地选用冷却作用不太激烈的淬火介质，有助于减少裂纹的出现。

On the other hand, problems can be solved by improving the heat treatment technology, for example, before quenching and heating, apply borax at the places with sharp changes in section, or fill with iron wire, asbestos and fireclay to prevent local overheating and reduce the temperature difference caused by uneven size; Adopt the method of graded heating to reduce the internal stress caused by excessive temperature difference; On the premise of the properties of C-beam steel, the quenching medium with less intense cooling effect shall be selected as far as possible to help reduce the occurrence of cracks.

在C型钢生产过程中，很难避免冷却过程构成的板材剩余应力。因而，钢板切开变形严重影响客户运用。因而，控制冷却技能的优化和剩余应力场的猜测已成为炼钢职业的热点。

In the production process of C-beam, it is difficult to avoid the residual stress of the plate formed by the cooling process. Therefore, the cutting deformation of the steel plate seriously affects the customer's use. Therefore, the optimization of control cooling skills and the guess of residual stress field have become the hot spot of steelmaking profession.

In this work, the orbits of different orbits are extracted and tested, and the orbit extraction algorithm is verified. During the steel cutting process of C-shaped steel, bevel along the straight line to check the line and reinforcement. After three-dimensional reconstruction, it provides the function of reconstruction picture and orbit parameters, and in some cases, it summarizes the orbit error, supplies the tracking adjustment error algorithm, and carries out error adjustment on the lower computer through serial communication.
