Description
Technical Field
The invention belongs to the technical field of refractory materials, and particularly relates to a flow guide pipe for alloy powder and a preparation method of the flow guide pipe.
Background
In recent years, industries such as metal 3D printing, metal injection molding, high temperature alloy and the like have rapidly developed, and the quality requirement of alloy powder is higher and higher. The granularity, the distribution, the purity, the production efficiency and the like of the alloy powder are related to the preparation process technology of the alloy powder. The method for preparing the alloy powder by gas atomization has the advantages of fine granularity, high sphericity, high purity, low energy consumption, environmental friendliness and the like, and becomes a main direction of the international development of high-performance alloy powder preparation technology in recent years.
The honeycomb duct is one of the key parts of the gas atomization process, and is required to withstand high temperature of not less than 1500 ℃ in service, withstand temperature difference thermal shock of 800 ℃ in height, withstand scouring and erosion of high-pressure and high-speed alloy liquid, be incapable of cracking and slag falling in service and have the diameter expansion of the honeycomb duct within 10 percent. In such a harsh service environment, the quality of the alloy powder and the continuity of the production are seriously affected by the defects of low strength, erosion resistance and the like of the existing boron nitride material. Although zirconia honeycomb duct products exist in China, the honeycomb duct products have the problems of easy cracking, slag falling, no resistance to corrosion of alloy liquid, serious diameter expansion and the like in service. The honeycomb duct made of the foreign zirconia material has the same use performance, but the density of the honeycomb duct is lower (the apparent porosity is 14 percent, and the volume density is 4.8g cm)-3) And poor oxidation resistance to desolvation, leading to severe diameter expansion in use.

A preparation method of a flow guide pipe for alloy powder is prepared by adopting an air atomization method and specifically comprises the following steps:
1) weighing raw materials in proportion, and uniformly mixing in a mixer;
2) pouring the uniformly mixed raw materials into an electric arc for high-temperature melting;
3) blowing the molten liquid by high-pressure gas to remove carbon to obtain zirconia balls;
4) crushing zirconia balls;
5) pouring the crushed zirconia fine powder into a granulator, adding a binding agent for granulation, and sieving; 6) pouring the granulated material into a mould, and performing mechanical pressing;
7) preserving the temperature of the machine-pressed blank in a silicon-molybdenum rod resistance furnace at 1700-1760 ℃ for 4-8 hours;
6) and (6) inspecting and warehousing the finished product.
Compared with the prior art, the invention selects six stabilizers, and the zirconium oxide is stabilized without phase change and is very stable in service by using the idea of high-entropy alloy for reference because the zirconium oxide has a fluorite structure. Meanwhile, the added stabilizer has a combustion-supporting effect to densify the material, so that the thermal shock resistance is excellent in use, the erosion and the scouring of the high-speed high-pressure alloy are resisted, more than two of the stabilizer can be repeatedly used, and the problems that the flow guide pipe in the gas atomization process is poor in thermal shock resistance, cannot resist erosion and scouring, and is serious in diameter expansion can be effectively solved.
