Factors Determining the Tolerance of Section Steel

The main factors affecting the dimensional tolerance of steel include raw material quality, processing technology, equipment accuracy and detection methods.

‌Raw material quality‌: The quality of raw materials directly affects the dimensional tolerance of steel. If the composition of the raw materials is uneven or there are defects, it will cause dimensional deviation of the steel during rolling.

‌Processing technology‌: The selection and execution of the processing technology have an important impact on the dimensional tolerance. For example, uneven heating or too fast cooling can easily cause steel deformation; improper positioning during cutting may lead to inaccurate cut edge length.

‌Equipment accuracy‌: The accuracy of the production equipment directly affects the dimensional tolerance of steel. Unstable equipment operation or insufficient accuracy of the measuring tool will lead to dimensional deviation.

Detection methods‌: The accuracy and reliability of the detection methods also affect the control of dimensional tolerance. The use of high-quality detection equipment and methods can improve the accuracy of dimensional tolerance.
