The Prediction of the Mechanical Properties of Gray Cast Iron Based on the Anatomy Experiment of the Engine Cylinder Head

Abstract

In order to predict the mechanical property during the actual production of gray cast iron, to qualify the casting for the requirement of mechanical property and to control the cost, in this paper a series of anatomy and mechanical property experiments are conducted based on the automobile engine cylinder head processed through the actual production. The actual Brinell Hardness (HB) and the pouring parameters of the cast iron are acquired through the experiment. According to the pouring parameters, the cooling curve is obtained through the Inte CAST software simulation and the cooling rate is also calculated. Based on the existing property prediction model, the Brinell Hardness property prediction model of the engine cylinder head is deduced. The prediction results conform well to the actual data results.
