Description

technical field [0001] The invention relates to the fields of metal additive manufacturing and gas atomization powder production, and in particular to a bottom hole type crucible induction melting gas atomization powder production device and method. Background technique [0002] Metal additive manufacturing technology is known as the "third revolution" technology. At this stage, it has been applied in aerospace, medical implants, automobiles, molds, and prototype design. In the future, it will be used in key complex parts of high-end equipment. There is a larger application space. Although metal additive manufacturing has been applied at this stage, limited by material technology, there are only 20 to 30 kinds of alloy materials that can be maturely processed through additive manufacturing. Many complex parts cannot be additively manufactured using their original design materials. Only 304 / 316 stainless steel and other mature materials can be used as substitutes, but the fi...

Problems solved by technology

In the early stage of new material composition design and optimization process, if the technical solution is used, it will cause a huge waste of equipment and materials

[0005]CN204545419U relates to bottom-hole crucible induction melting gas atomization powder making, but it is more focused on the overall structure of equipment in a larger range, and the structure of key positions in the equipment , assembly method and milling process and parameters are not mentioned

In addition, in the actual gas atomization powder making experiment or production, there will be problems of "leakage" between the catheter and the inner crucible and the problem of poor fit between the catheter and the stopper rod. The former will cause the atomization nozzle or equipment to be alloyed. The melt is "scalded", which will cause the catheter to block and prevent the subsequent atomization process. The patent does not mention such engineering problems

[0006]The CN207222887U technical solution also involves bottom-hole crucible induction melting, but in fact this patent is a device for preparing amorphous alloy strips, although it can meet the requirements of gas atomization single crucible melting And diversion needs, but this technical solution does not involve the technical points of gas atomization pulverization

Secondly, the alloy melt above 1300°C has a small viscosity coefficient and better fluidity. If the catheter and the crucible are not well matched, the alloy melt will leak. First, it will waste materials, and second, it may cause equipment damage.

Finally, the crucible of this technical solution adopts a "cylindrical" structure, and some melt at the bottom may adhere to the bottom surface more, resulting in material waste

[0007]The existing gas atomization powder making device and technical scheme cannot meet the trial production of small-scale customized new material alloy powder. This technical scheme only uses a set of melting power supply, coil And crucible, can realize small batch customized powder making
