Heating device and method for preparing diffusion alloy powder for detachable tube furnace

Abstract

The invention provides a heating device and method for preparing diffusion alloy powder for a detachable tube furnace. The device comprises a furnace tube, a flange, an air outlet, a stirring structure, an air inlet and a motor. The flange is used for fixing the furnace tube on a tube furnace body, and the stirring structure is connected with the motor and fixed on the flange, so that the stirringstructure is arranged on a central shaft of the furnace tube. The air inlet and the air outlet are used for feeding and discharging gas. Materials are put into the furnace tube, and the materials areuniformly heated by controlling the stirring rate and the stirring structure. The device can be used in various types of tube furnace hearths, is convenient to disassemble, avoids the waste of laboratory resources, and saves the experiment cost. Moreover, the stirring structure is used for mixing materials, so that the problems of poor air tightness and stability of the tubular furnace caused byrotating the furnace body are avoided. The composite powder prepared by the device can be used in the fields of 3D printing, cold spraying, powder metallurgy and the like.

Description

technical field [0001] The invention relates to a heating device and method for preparing diffusion alloy powder, which is mainly used in the preparation of diffusion alloy powder in a tube furnace. [0002] technical background [0003] Most of the powder heating devices in the existing tube furnace rotate the furnace body to achieve the uniformity of material heating. However, such a heating method makes the tube furnace only used for heating powder and cannot be used for other heating experiments, which often increases the cost of experiments. At the same time, during the rotation of the furnace body, it is easy to cause the problems that the entire furnace body is not tightly sealed and the stability of the equipment is not high. Contents of the invention [0004] The technical problem to be solved by the present invention is to design a device for preparing composite powder that is detachable, uniform in heating, good in sealing performance, and stable in equipment op...
