Quality control requirements for IPBL360 German standard H-beam.
I. Introduction. With the continuous development of construction projects, H-beam is an important building structure material, and its quality requirements are becoming more and more stringent. As a high-strength and high-quality steel, IPBL360 H-beam has been widely used in the construction industry. In order to ensure its quality and safety, the quality control requirements for IPBL360 H-beams are becoming increasingly stringent.
Second, the characteristics of IPBL360 German standard H-beam.
1.High strength: IPBL360 German standard H-beam has high yield strength and tensile strength, which can meet the bearing requirements of various complex structures.
2.Excellent processing performance: IPBL360 German standard H-beam has good welding performance and cutting performance, easy to process and assemble.
3.Environmental protection: The use of high-quality environmentally friendly materials in line with the requirements of green buildings.
3. Quality control requirements.
1.Quality control of raw materials.
Select high-quality iron ore, scrap steel and other raw materials to ensure that the chemical composition is qualified.
Raw materials are inspected for quality to ensure that there are no defects and impurities.
2.Production process control.
Advanced rolling technology and heat treatment technology are used to ensure the stability of steel structure and performance.
Strictly control the temperature, pressure, time and other parameters in the production process to ensure the consistency of product quality.
3.Dimensional and appearance quality control.
Ensure that the size of the H-beam meets the requirements of the national standard or German standard, and the error of length, width, height and other parameters is within the allowable range.
The appearance of the H-beam is inspected to ensure that the surface is smooth, free of cracks, bubbles and other defects.
4.Mechanical property test.
The mechanical properties of the finished H-beam are inspected, including tensile strength, yield strength, elongation and other indicators to ensure that they meet the requirements of the standard.
5.Non-destructive testing.
Ultrasonic testing, magnetic particle testing and other methods are used to carry out non-destructive testing on H-beam steel to ensure the internal quality of the product.
