Common quality problems of angle steel:
1. Surface quality problems: There are burrs, scales, rust and other problems on the surface of angle steel, which affect the appearance and service life.
2. Dimensional accuracy problems: The dimensional accuracy of angle steel is not enough, which may cause failure to fit or deviation during use, affecting the assembly accuracy.
3. Chemical composition problems: The chemical composition problems such as impurities and inclusions in the angle steel may lead to the decline of mechanical properties such as strength and toughness.
4. Internal quality problems: There are quality problems such as cracks and defects inside the angle steel, which may cause safety hazards such as breakage during use.
Solutions to quality defects of angle steel:
1. Surface treatment: Surface treatment of angle steel during the production process, such as pickling and sandblasting, can effectively remove burrs, scales, rust and other problems, and improve the surface quality of angle steel.
2. Precision control: During the production process, the dimensional accuracy is strictly controlled to reduce dimensional deviation and improve assembly accuracy.
3. Quality control: Establish a complete production quality control system to monitor the chemical composition and internal quality of angle steel, and promptly discover and deal with problems.
4. Material selection optimization: Select high-quality raw materials to reduce chemical composition problems such as impurities and inclusions in angle steel, and improve the mechanical properties of angle steel.
Advantages of angle steel:
Angle steel is a commonly used building structure material with the following advantages and characteristics:
1. High strength: The cross-sectional shape of angle steel is equilateral, with high strength and can withstand large loads. Angle steel is made of cold-bent or hot-rolled steel plates, and its strength is much higher than that of ordinary steel, and it can withstand large loads.
2. Stable structure: The cross-sectional shape of angle steel is a right angle, which makes it have good stability when subjected to force and can resist deformation and distortion.
3. Convenient construction: The cross-sectional shape of angle steel is regular, easy to cut and connect, and the construction process is simple and convenient.
4. Rich specifications: The specifications of angle steel are diverse, which can meet the needs of different projects, such as L-shaped angle steel, equilateral angle steel, etc.
5. Good corrosion resistance: Angle steel can be galvanized, sprayed and other anti-corrosion treatments to improve its corrosion resistance and extend its service life.
6. Low cost: Angle steel is a common building material with relatively low cost and is suitable for a large number of engineering structures.
Application areas of angle steel:
1. Construction field: Angle steel is widely used in the construction field, such as building structures, stair handrails, railings, doors and windows, etc.;
2. Machinery manufacturing: Angle steel can be made into various mechanical components, such as machine bases, profiles, supports, etc.;
3. Transportation: Angle steel can be used to manufacture transportation facilities such as bridges, tunnels, and highway guardrails;
4. Energy field: Angle steel is also widely used in electricity, petroleum, chemical industry and other fields.
In short, the quality problems of angle steel need to be paid attention to and solved in the production process. Only by strengthening quality control and supervision and improving product quality can we better meet the needs of the construction industry.
