摘　　要：以220#、320#、1000#的电熔莫来石粉(EC95粉)为面层耐火材料原料,采用不同粒度配比的EC95粉进行陶瓷型壳面层料浆的配制,研究了粉液比相同条件下,粉料粒度对面层料浆粘度、板重、型壳表面粗糙度及铸件粘砂的影响。研究结果表明:粉液比在4∶1的条件下,以20%的220#EC95粉、65%的320#EC95粉、10%的1000#的EC95粉配制的面层料浆具有较优的涂挂性能,粘度在25 s,板重在4.10 g,表面粗糙度在2.16μm,制备的单晶型壳能解决叶片铸件的粘砂问题。By using 220#,320#,1000#electric melting mullite powder(EC95 powder)as raw material of the primary layer,the primary layer slurry with different ratio EC95 powder was prepared.Effect of powder particle size was studied on viscosity of slurry,plate weight,shell surface roughness and sand sticking of castings.The results showed that the slurry prepared with 20%220#EC95 powder,65%320#EC95 powder and 10%1000#EC95 powder at the ratio of 4∶1 had better coating performance.The viscosity was 25 s.The plate weight was 4.10 g and the surface roughness was 2.16μm.The single crystal shells were made by this process which can solve the problem of sand Sticking.
