Development and Production of Forklift Nodular Cast Steering Knuckle in DISA Line
This paper mainly introduces the technical requirements of forklift steering knuckle and the casting process in DISA line.In view of the problems encountered in the process development,such as the shrinkage hole of the riser neck,the sand hole of the casting and the unqualified performance of the test bar,the corresponding solutions were put forward by analyzing the casting process.By adopting the bottom pouring system and the top ball riser feeding,improving the core print structure of the hot sand core,adding Cu,Cr and other alloying elements during melting,adopting the measures of first-inoculation in the transfer ladle and second-inocu-lation in the casting process,the high performance forklift steering joint castings have been successfully produced on the DISA line.
