The invention discloses a preparation method of an extra-high voltage safe power transmission tower. The preparation method comprises the following steps that firstly, the proportion of each part of a steel billet is regulated and controlled, and a steel billet material of each part with high strength and high weather resistance is prepared; then, the steel billet material is polished, so that the sum of the areas of the protrusions, the pitted surfaces and the pits on the surface of the steel billet material does not exceed 5% of the surface area of the steel billet material, the depth of the pits is smaller than 0.3 mm, the height of the protrusions is smaller than 1 mm, and the surface of the steel billet material subjected to polishing treatment is galvanized; steel billet assemblies subjected to surface treatment are welded, and the steel billet assemblies are assembled into a complete iron tower structural member; and finally, the surface of the iron tower structural member is coated with a protective layer, and anti-corrosion treatment is carried out. By the adoption of the preparation method, the iron tower structural part with high strength and high weather resistance can be prepared, the surface of the iron tower structural part is coated with an anti-corrosion protection layer, the anti-corrosion performance of the iron tower can be effectively improved, and the iron tower prepared through the preparation method has the long service life and can meet the requirement for long-time use of ultra-high voltage power transmission.
本发明公开了一种特高压安全输电铁塔的制备方法，包括以下步骤：首先，调控钢坯的各组分配比，制备高强度高耐候性的各组件的钢坯材料；然后，打磨钢坯材料，使得钢坯材料表面的凸起、麻面、凹坑的面积之和不超过钢坯材料表面积的5％，凹坑的深度＜0.3mm，凸起的高度＜1mm，并在打磨处理后的钢坯材料表面镀锌；焊接表面处理后的各钢坯组件，组装成完整的铁塔结构件；最后，在铁塔结构件的表面涂覆保护层，做防腐处理。采用本发明的制备方法，可以制得具有高强度、高耐候性的铁塔结构件，并在铁塔结构件的表面涂覆防腐保护层，可有效的提高铁塔的防腐性能，通过本发明的制备方法制备的铁塔具有悠长的使用寿命，可满足特高压输电的长时间使用。
