下面介绍几种正在工业上使用或试用着的有成效的流动粒子炉。一、用电阻丝(带)加热的流动粒子炉用电阻丝(带)加热的流动粒子炉也分低温、中温和高温,可以热处理有色金属,如铝、铜及其合金,也可以热处理合金钢及其他碳钢,各国都在研究,使用和推广。美国波音航空公司建有数百台大大小小的流动粒子炉,从实验规模的小炉子到工业设备的大炉子都有,用他们对工件进行加热和冷却处理,成功地把36吋长的合金钢扇形环(A.I.S.I_(4330)-m)进行淬火冷却。工件加热到870℃后放在温度为320℃的流动粒子炉中保温2小时。经过粒子炉处理的合金钢扇形环其挠曲度小于0.001时。在普通的淬火介质中淬火时,由于工件形状复杂,挠曲度要大得多。
Here are a few of the industrially used or tried-out mobile particle furnaces. First, the use of resistance wire (with) heated particle furnace resistance wire (with) heated mobile particle furnace is also divided into low temperature, medium temperature and high temperature, you can heat treatment of non-ferrous metals, such as aluminum, copper and their alloys, but also heat treatment of alloy steel And other carbon steel, all countries are studying, using and promotion. Boeing America built hundreds of large and small mobile particle furnaces, ranging from small experimental stoves to big industrial furnaces, heating and cooling the workpieces to successfully transfer 36-inch-long alloy steel Fan ring (AISI_ (4330) -m) for quench cooling. The workpiece was heated to 870 ° C and placed in a flow particle oven at a temperature of 320 ° C for 2 hours. After the particle furnace alloy steel fan ring deflection of less than 0.001. Quenching in the ordinary quenching medium, due to the complexity of the workpiece shape, the deflection is much larger.
