| Abstract: | This paper describes the temperature fields and solidification process in armoured steel castings under all kinds of conditions. By using the finite element method and graphic technology with the aid of computer, the formation mechanism of hot tearing of castings with resin bonded sand cores has been revealed. Different casting tests were simulated with the aid of CAD technique and the results were used in foundry to remedy the serious cracking scrap problems and to produce high-quality castings. |
