越来越多的制造商正在用感应热处理取代渗碳工艺,只因感应热处理的快速加热与冷却的精确控制可以得到他们所需要的金相组织。感应热处理的优点:
1. 很小的淬火变形 感应淬火只加热工件表面,避免了透热,快速加热与冷却减少了变形,减少了加工费用与校直工序。
2. 优越的金相组织 工件只在表面加热 ,加热周期短,避免了组织粗大。
3. 较高投入产出 生产周期短,支持高投入产出和流水线生产。
4. 可采用密集的设备安装 感应设备需要很少的安装地面,并可立式安装以减少安装场地。
- Ability to harden extremely large workpieces – Induction hardening can treat very large workpieces (e.g., 6-meter-diameter rings).
- Production scheduling flexibility – Like the microwave oven in your kitchen, induction heating is instant on/instant off, with no need for lengthy warm-up, cool-down cycles. Production planners have greater freedom when scheduling small lot sizes and one-off parts.
- On-line quality control – Modern induction systems feature energy monitoring systems and hardness checkers for automated on-line QC of each and every workpiece while it is in process.
- Reduced energy consumption – Induction hardening primarily heats the surface instead of the entire workpiece. The heating cycle is necessarily short, and total energy consumption is low.
- Low emissions – Induction hardening produces essentially no CO2 emissions.
