Bending and processing of extra-large angle steel for ultra-high-voltage transmission towers. 近日由居龙钢铁承制加工的特高压输电铁塔用特大规格角钢顺利交付相关建设单位

With the rapid development of the national power grid, extra-large angle steel is playing an increasingly important role in the construction of ultra-high-voltage transmission towers. Due to their large flange widths and thicknesses, these extra-large angle steels place higher demands on processes such as raw material inspection, cutting, bending, and galvanizing. To ensure effective quality control of transmission tower products throughout the production process, Julong Steel has comprehensively optimized its processing techniques for extra-large angle steel and implemented strict quality control measures.

随着国家电网建设的飞速发展，特大角钢在特高压输电铁塔应用中承担着越来越重要的作用，特大规格角钢肢宽与肢厚均较大，对原材料的检验、下料、制弯、镀锌等工序提出了更高的要求，为确保铁塔产品检验在生产过程中得到有效控制，居龙钢铁对特大角钢加工工艺进行全面优化，严格质量控制。

The processing of extra-large angle steel poses significantly greater challenges in terms of difficulty, manufacturing processes, and precision compared to standard-sized angle steel, and it demands much higher standards for processing technology and equipment. As the voltage levels of high-voltage transmission towers in China continue to rise, the loads on these towers are also increasing. Conventional angle steel can no longer meet engineering requirements, and the production of extra-large angle steel presents challenges for processing companies, driving significant advancements in manufacturing processes and quality control.

特大角钢加工难度和加工工艺及精度较普通规格角钢加工工艺、加工技术装备要求高许多。随着我国高压输电铁塔电压等级的不断提高，致使铁塔的荷载也在不断提高，常规的角钢已不能满足工程要求，特大规格角钢，给加工企业带来挑战，促使加工工艺和质量控制得以重大发展。
