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.
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.
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.
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.
