This paper presents a technique for controlling the pressure of a molten metal when using a new type of iron casting method called sand mold press casting to realize high productivity and obtain high-quality *** past test results using this method showed a casting yield of 90% to 95%,while conventional methods only show a casting yield of 60% to 70%.Although the press casting method does not require a sprue cup or runner channel casting defects such as metal penetration are often caused by the high pressure in the high-velocity pressing part of this casting ***,we proposed a pressure control method with a mathematical model of molten metal pressure,and with it we achieved experimental confirmation of the successful production of brake drums at different pressing *** show that the proposed pressing control method can realize sound,penetration-free casting ***,the theoretical analysis and design of this pressing process had not previously been studied sufficiently,and therefore this paper presents the theoretical design algorithm for the process as well as its experimental confirmation.

＜正＞This paper presents sloshing suppression control during a ladle *** this paper,a mathematical model comprised of the continuous equation and the pressure equation is used,and the sloshing phenomena are analyzed by using Boundary Element Method（BEM）.Therefore,liquid levels at several evaluation points are derived and estimated sloshing,including higher-order ***,the sloshing is suppressed by using Model Predictive Control method（MPC）.The effectiveness of proposed control system is shown thorough experiments and simulations with CFD.
