研制了一种能从高粘度流体中去除马氏体相变不锈钢颗粒的磁选机。在化学品和食品等工业产品的加工过程中，不锈钢磨损碎屑从生产线的可移动部件中混入高粘度的工作流体中。有必要去除这些杂质，因为这些杂质可能是质量损失的因素。近年来，由于对工作流体粘度的要求增加到10以上，碎片的分离效率急剧下降。去除小于25微米的碎片变得更加困难。为解决这一问题，研制了超导高梯度磁选机。为了实现高粘性流体中碎屑的高效分离，本文通过计算和实验给出了该系统的设计原则。
A magnetic separator which can remove martensitic transformed stainless steel particles from highly viscous fluid was developed. In the process of industrial products such as chemicals and foods, stainless steel wear debris are mixed from the movable parts of the manufacturing line into highly viscous working fluid. It is necessary to remove these impurities, because these can be the factor of the quality loss. Recently, the separation efficiency of the debris is decreasing drastically because the requirement of the viscosity of the working fluid is increasing over 10 . It becomes more difficult to remove the debris with smaller than 25 micrometers. To solve the problem, superconducting high gradient magnetic separator was developed. We report the design guideline of the system based on the calculation and experiments to achieve high separation efficiency of the debris from the highly viscous fluid.
