| Abstract: | Using engineering method, approximate mould condition and taking the surface as blending surface, the thixoforming force of 7075 alloy obtained by liquidus semi continuous casting was calculated. The results show that at the beginning and the ending of the thixoforming, the thixoforming force is 32 and 667.09?kN respectively. The calculated result, 667.9?kN, agrees well with the measured result, 721?kN between them there is a permissible error of 7.4%. [ |
