.4100 The Qb Cylinder Head Casting Production And Quality Control

Kunming Yunnei Dongli Co.,Ltd introduced into a air flow squeeze moulding line of German compang KW in 1995, It is used to produce cylinder-head and cylinder-block of " 100 series" diesel engine mainly? The KW moulding line is 90' s international level and advanced and automatic casting produce line,, Based on the complex of castings, the moulding machine can adopt three ramming methods: Squeezing ramming Squeezing ramming and opposite squeezing Squeezing ramming and opposite squeezing and airpressplus, the moulding line has an interface of man.machine conversation, it' s successful use broke the intrinsic machine molding and close production mode of our company New equipments new technique new process, and faces to new questionsoIn this paper, Introduce the foundry technology and equipments of 4100QB cylinder-head; The produce capacity of the KW moulding line have achieved 1100 regular molds per day, and produce 25 thousand tons eligible castings per year; This paper apply and combine the latest casting theories and plenty of experimentation datum, Discuss the reasons of defective casting and the resolvents in production process on rupture of vent-pipe core dispersed shrinkage at nozzle blowhole and so onand the cylinder-head reject rate reaches ≤3%, Quality of casting is advanced in china, It achieves high technicality and economic effectiveness And afford the resolvents of quality control for producing cylinder-head casting of else series diesel engine It is direct production technology reconstruction practicability, and process high theory level and high applied worthiness It supplies use for reference for the foundry industry to introduce into the moulding line...
