Cold rolled steel strips for springs of color display tubes
Color display tubes are widely used in our daily life, often being used in TV and other similar display equipment, indicating that the usage of cold rolled steel strips to produce springs of color display tubes is increasing over time in the related industry. Therefore, it has become essential to uphold specific standards for producing such steel strips, such as YB/T110-1997 – cold rolled steel strips for springs of color display tubes.
This standard comprises basic requirements for cold rolled steel strips for springs of color display tubes, technical requirements of delivery, inspecting methods, signs attached to steel strips, process of inspect and examination as well as packaging and marking.
Cold-rolled steel strips for springs of color display tubes used in this standard are made of non-stainless steel according to YB/T203-1996. It goes into the same level of rolling and inter-selling as the cold-rolled strips obtained by the general nomenclature process and it has high strength, low carbon content and goes through a strong stretching process.
The basic requirements of cold rolled steel strips for springs of color display tubes are as follows:
1. The material used in the production of cold rolled steel strips for springs of color display tubes must be of non-stainless steel according to YB/T203-1996, making sure that it meets the requirements of chemical composition, mechanical properties, and surface quality.
2. The width of the steel strips must range between 12mm to 17mm according to the actual requirements. It is recommended that the steel strip should have a thickness of 0.3mm with a tolerance between 0.29mm and 0.32mm.
3. It is required that the steel strip should pass through eight stretches of the thickness reduction method, capable of 40% cold work hardening. The tensile strength of the steel strips should be between 290 MPa to 440 MPa and the elongation should be between 10% and 25%.
4. The surface of the steel strips should have a certain amount of white rust. If a smooth surface is required, the white rust should be removed through cleaning.
This standard for cold rolled steel strips for springs of color display tubes is essential for the industry in order to maintain high-quality steel strips used for springs of color display tubes. The utilization of cold rolled steel strips for springs of color display tubes is becoming increasingly important as more and more springs of color display tubes are being produced globally. The adherence to this standard promotes the quality control and effectiveness of the related products.
In conclusion, YB/T110-1997 for cold rolled steel strips for springs of color display tubes is essential for providing quality control of the springs of color display tubes, as well as maintaining the stability of steel strip materials used in production. The implementation of this standard thus brings benefit to the industry, maintaining a high-quality production and ensuring long-lasting springs of color display tubes.
