瑞典一家公司制造了一种能检查1000℃左右的钢和其它金属板材和坯材表面缺陷的设备。这种设备能立即用热剥的方法,把各种缺陷修补好。 常用的工艺是把板材冷却到常温,然后作人工检查,把缺陷打磨掉。热轧时,还要将板材重新加热。瑞典研制的这种设备不要再重新加热,可以节省大量能源。 这种新设备是根据涡流技术设计的。 A company in Sweden made a device that checks the surface defects of steel and other metal sheets and blanks at about 1000 ° C. This equipment can immediately use thermal stripping method to repair a variety of defects. Commonly used process is to cool the plate to room temperature, and then for manual inspection, the defects polished. Hot-rolled, but also re-plate heating. The equipment developed by Sweden is not reheated and can save a lot of energy. The new equipment is based on eddy current technology.
