描述

硬化焊条 are specially designed consumables for hardfacing or overlay welding, 提供 极高的耐磨性和抗冲击性 to industrial equipment.
They are commonly used to deposit a wear-resistant layer 在 steel surfaces, 管道, and tubes, extending the service life of machinery in 矿业, 水泥, 力量, 和物质处理行业.

Types of Hardened Welding Consumables

1. Hardfacing Welding Rods

材料: 通常 碳化铬, 高碳钢, or cobalt alloys.
形式: Stick, wire, or flux-cored rods.
堆焊硬度: 50–65 HRC depending on alloy.
应用领域:
- 破碎机衬里, 料斗, 铲斗边缘
- 搅拌机叶片, 螺旋输送机, 瀑布
- Shredder blades and impact surfaces

优点:

Easy to use in manual or semi-automatic welding
Deposits uniform hardfacing layers 具有优异的耐磨性
适合于 repairing or reinforcing worn parts

2. Hardfacing Tubes / 管道

定义: Tubes or pipes that have a hardfacing overlay welded or lined internally.
目的: Protects pipelines carrying abrasive slurry, 矿石, 煤炭, 或沙子 from erosion and wear.
覆盖材料: Chromium carbide or tungsten carbide layers applied inside or outside the tube.
