为解决冶金轧辊大面积激光涂敷的需要，研制了一套宽带激光自动涂敷系统．它由宽带扫描转镜和自动喷粉机组成，适用激光功率１～１０ｋＷ，既可用于宽带涂敷，又可直接用于聚焦窄带涂敷；单道一次涂敷宽度１０～３５ｍｍ连续可调，涂敷厚度０．２～８ｍｍ可控；送粉量０．５～２００ｇ／ｍｉｎ连续精密可调，送粉精度＜２％．它不仅适用于普通送粉，而且也适用于特殊条件下的微量送粉和大粉量送粉．送粉材料适应性广，不仅用于一般Ｎｉ基、Ｆｅ基等粉末，而且能用于ＷＣ、ＴｉＮ等硬质合金粉、Ｃｕ粉和超细微陶瓷粉，如Ａｌ２Ｏ３、ＺｒＯ２等，粉末粒度１６～１５０μ，送粉利用率高达９８％以上．该套系统采用专利结构制成，结构紧凑，外形美观，已用于轧辊的大面积涂敷和激光淬火、汽车凸轮轴激光淬火和熔凝处理、轧辊和曲轴等零件表面补焊等方面．
In order to solve the need of large-area laser coating of metallurgical rolls, a broadband laser automatic coating system was developed. It consists of a broadband scanning turn mirror and automatic duster, suitable laser power 1 ~ 10kW, can be used for broadband coating, but also can be used directly for narrow-band coating; single-pass coating width of 10 ~ 35mm continuously adjustable, Coating thickness of 0.2 ~ 8mm control; feeding capacity of 0.5 ~ 200g / min continuous precision adjustable, feeding accuracy of <2%. It not only applies to ordinary powder, but also for special conditions, the amount of powder and powder delivery of large quantities. The wide adaptability of the powder feeding material is not only used for general Ni-based and Fe-based powders, but also for cemented carbide powders such as WC and TiN, Cu powder and ultrafine ceramic powders such as Al2O3 and ZrO2, 150μ, powder utilization up to 98%. The system uses a patented structure, compact structure, beautiful appearance, has been used for large-scale roll coating and laser quenching, automotive camshaft laser quenching and fusion processing, roll and crankshaft and other parts surface welding and so on.
