smaller than a linear system. Can Eng also added a force recirculation system for low temperature operation and integrated robotic part handling. Can Eng’s Basketless Heat Treating System utilizes one
rotary hearth furnace for solution treatment, one rotary furnace for aging and a small quench system that does not require large pits in the facility floor. Instead of heating and quenching large baskets loaded with parts at one time, a single part or a small group of parts are placed into a smaller system more frequently, eliminating the need for baskets and reducing fuel consumption by 40%. Additionally, the system requires fewer mechanical components to operate—a single circulation fan and drive—which leads to less maintenance. In situations where more precision is required, particu-
larly for thin-wall parts with various cross-sections, Can Eng developed a Precision Air Quench (PAQ) system that enables uniform cooling to reduce residual stresses. Coupled with the basketless heat treat system, the PAQ system fur- ther reduces the size of the quenching system. Te basketless heat treat system’s one-part-in, one-part-out

design reduces inventory and allows castings to be brought to solution and aging temperature 30% more quickly than in conventional roller hearth systems. Te temperature profile of parts is more uniform, since the parts are no longer packed into
的高度会增加，但占地面积还不变。这种系统的占地面 积比原来小了33%。Can Eng也增加了用于低温生产的 强制循环系统和工件自动处理系统。
Can Eng的无料筐热处理系统采用一个转底炉用于 固溶处理，一个回转窑用于时效处理，一个不需要很大 占地的小型淬火系统。单个工件或一组工件被快速地放 置在更小的系统中，这样就不需要使用料筐，并减少了 40%的燃料消耗，而之前需要在同一时间对整个料筐 进行加热和淬火。除此之外，系统的机械零部件也变少 了，使得维护变得更加容易，例如采用单独的循环风机 和动力。
在一些需要精密处理的条件下，尤其是横截面复杂的 薄壁件，Can Eng发明了精密空冷（PAQ）系统来保证铸 件各部分的均匀冷却，以降低残余应力。和无料筐热处理 系统一样，PAQ系统进一步减小了淬火部分的尺寸。
无料筐热处理系统部分热处理的设计减少了铸造设备 的库存，与传统的转底炉系统相比，固溶和时效时间加 快了30%。零件内部的温度场分布更加均匀，因为这部
分不会像先前一样被装入料筐中。 ■ 获得更多信息请登陆

Dutch Pump Maker Bets on 3-D Printing 荷兰Pump制造公司看好3D打印的发展
Sand casting molds from 3-D printers offer numerous
advantages, from shorter throughput times and less follow- up work to better surface quality of unfinished castings. Pump manufacturer Nijhuis, Winterswikj, Te Nether-
lands, casts pump housings and wheels weighing up to 800 kg. Te Dutch firm develops and builds pumps made-to- measure, so short prototype production times are important. To meet this prototype demand, Nijuis has concluded sev- eral projects with printing technology from voxeljet, Fried-
通过3D打印机制造出的砂型具有众多优势，例如更 短的生产时间，更少的用于后期进行表面处理的工序 等。
泵制造商Nijhuis（Winterswikj，荷兰）铸造了重 达800千克的箱体和车轮。这家荷兰公司生产的泵都是 按照客户要求量身定做的，因此缩短原型的研发时间 就显得尤为重要了。为了达到这样的要求，Nijuis已经
