预热
感应预热是一种在对材料或工件做进一步加工之前通过感应技术对其进行加热的工艺。
简介
使用预热的原因因行业而异。在电缆和电线行业中，电缆芯会在绝缘挤压之前进行预热。钢带会在酸洗和镀锌前进行预热。感应预热还可以在弯曲之前软化金属，以及备好管材进行焊接。移动预热解决方案有助于轴承组件的现场维修。
- 极为高效的预热，大大节约能源
- 循环时间短和连续自动匹配意味着单个感应器可以处理广泛的产品范围
- 体积小且易于集成到现有或规划的生产线中

Induction heating is increasingly used to remove the giant nuts and bolts in power stations’ turbines.
-
ENRX designs and builds specialised systems for steel strip and wire and cable pre-heating.
-
Minac units are frequently flown to oil platforms to perform repairs and maintenance.
