- 摘要:
- 通过正交试验研究了耐火材料粉末种类、粉末目数、助熔剂种类、焙烧温度对3D打印用精密铸造粉末的高温抗压强度、高温抗拉强度、尺寸收缩率、表面粗糙度的影响。结果表明,确定的3D打印用精密铸造粉末的最终材料为添加氧化铜的325目锆英粉在1400℃下焙烧得到抗压强度为45.42 MPa、抗拉强度6.78 MPa、尺寸收缩率为6%、表面粗糙度Ra为3.45的高性能型壳。
The influences of refractory powder types,mesh number of powders,flux types and calcination temperature on the high temperature compressive strength,high temperature tensile strength,size shrinkage and surface roughness of precision casting powder for 3D printing were studied by orthogonal experiment.The results show that the final materials of 3D-printing precision casting powder is 325-mesh zirconia powder with copper oxide and roasted at 1400℃to obtain a high-performance shell with compressive strength of 45.42 MPa,tensile strength of 6.78 MPa,dimensional shrinkage rate of 6%and surface roughness Ra of 3.45.
