摘要： PROBLEM TO BE SOLVED: To prevent the development of gas defect in a casting and chilling part on the surface of the casting by preventing gas from being entraped into molten metal even in the case of charging the molten metal into a mold at high speed. SOLUTION: In this casting method for a cast iron, by which the molten cast iron stored in a crucible 4 is charged into a cavity 13 in the mold by utilizing pressure difference between the inner part of the crucible 4 for storing the molten cast iron and the inner part of the mold 10, when the molten cast iron is charged into the cavity 13, the gas venting in this cavity 13 is executed and also, the mold 10 is rotated with a sprue 13y as the center. In this way, the molten metal is charged up to the end part of the cavity 13 with the action of the centrifugal force. On the other hand, releasing agent gas, etc., generated in the cavity 13 is collected into the rotating center part from the end part of the cavity 13 by being pushed with the molten metal and is discharged to the outside.

摘要： PURPOSE:To attain a quick control response by outputting a control signal corresponding to a target value of heating power. CONSTITUTION:A main control device 42 receives a heating power pattern from a power input device 41, and calculates and outputs a main control signal according to the pattern in accordance with this power characteristic. A sub- control device 43 is provided with a power characteristic, receives the deviation between the target value of the power pattern and an actual heating power, and calculates and outputs a sub-control signal according to the deviation in accordance with the power characteristic. An adder 44 receives the main and sub-control signals, and controls an AC power source 50. The power source 50 is an induction heating power source for a melting furnace 10, and carries a control current to the heating coil of the furnace 10. When a target heating power value is changed, thus, the device 42 immediately outputs the control signal according to the target value, which is then applied to the power source 50 through the adder 44. Since the heating power can quickly follow the target value, therefore, the occurrence of an overshoot or hunting can be prevented.

摘要： PROBLEM TO BE SOLVED: To provide an engine structure capable of providing a high strength and a manufacturing method thereof. SOLUTION: A cylinder head 2 equipped with a cooling water passage 12 is formed by performing a casting in the state where a hollow core 14 is arranged in a mold, and the hole formed by removing the hollow core is used as the cooling water passage 12. In the casting, the temperature reduction of the molten metal in the mold is accelerated by passing water to the hollow core. Accordingly, the reduction in material density of the cylinder head 2 according to the delay of solidification of the molten metal can be suppressed.

摘要： PURPOSE: To provide a forming method of a lost wax mold to manufacture the long casting free from porosity by forming the lost wax mold which is long in shape and uneven in wall thickness. CONSTITUTION: A wax mold formed in the cavity shape to be formed is dipped in the slurry for forming the mold containing the refractory powder, and the slurry coated film is formed on the surface of the taken out wax mold. The thickness of the lower part of the coated film to be formed by the dipping in the slurry is larger than that of the upper part due to the sagging of the slurry by the gravity between the upper and lower parts when left standstill. After the difference in the thickness of the coated film is obtained, the refractory powder is scattered to change the attached amount of the refractory powder. By repeating these works, the mold having the directional solidification in the longitudinal direction is obtained. When the wax pattern is removed and the molten metal is poured, the cooling speed of the casting can be controlled to form the excellent casting free from porosity.
