サブマージアーク耐摩耗性複合鋼板
サブマージアーク耐摩耗性複合鋼板: プロセスの特性と用途
1. 高い生産率
Submerged arc cladding boasts a high production rate due to its use of large currents, typically between 300-500A and sometimes reaching up to 900A. これにより、高い蒸着速度が可能になります.
2. Mechanization and Automation
プロセスは高度に機械化され、自動化されています. It produces a cladding layer with stable performance and an attractive appearance, rarely exhibiting defects like pores or slag inclusions. The welders do not need advanced skills, yet the resulting submerged arc composite steel plates offer excellent wear resistance.
3. Clean and Safe Operation
The arc is completely covered by flux, preventing spatter and reducing cleaning efforts. さらに, アーク放射はありません, eliminating the need for special protective gear for the operator.
4. 機器の制限
The equipment used is large and difficult to move, 現場での被覆工事が困難になる. Flux must be dried and stored properly before use.
5. Heat and Dilution Concerns
The heat transferred to the workpiece is higher than in other arc welding methods, resulting in a high dilution rate. To achieve the desired performance, 2-3 layers are often necessary. Due to the significant thermal gradient, preheating and slow cooling are usually required to prevent cracking. しかし, if the preheating temperature exceeds 315℃, slag removal can become difficult.
6. Suitable Workpiece Types
The process creates a large molten pool, making it suitable only for horizontal position surfacing. It is ideal for cylindrical and large flat workpieces but not for small parts.
アプリケーション
Submerged arc surfacing is the most widely used method for surfacing iron-based materials. It is commonly employed for surfacing corrosion-resistant layers on the inner walls of large-diameter containers and for adding wear-resistant layers to rolling mill rollers. This method is also the primary way to produce wear-resistant composite steel plates.
