摘要： A method of casting has a mold assembled on a base plate. The finished mold is rotated by approximately 180° around a horizontal rotational axis. A casting container with an upwardly positioned aperture end, removed from the mold, is filled with melt for one casting operation. The casting container is sealingly coupled by the aperture end to the ingate end of the mold. The mold, together with its contacting casting container, is rotated by approximately 180° around a horizontal axis. Accordingly, the melt reaches the mold, and the casting container is removed from the coupled position away from the mold.

摘要： The invention relates to a process and devices for casting components in metal alloys on the tilt casting principle in which a quantity of melt metered for casting is spread over a large gate cross section without turbulence from a melt container of the mould (30) into the mould (31) by rotating the casting device. To prevent the formation of oxide and weak structural points, the melt is taken from a metering furnace under a protective gas in a melt container connected to the mould and taken thence into the mould also under a protective gas. The melt hardens there under increased gas pressure on the feeder region of the casting, whereby its properties such as fine-grained, dense structure, high stability under load and accurately dimensioned surfaces are considerably improved.

摘要： In a melting furnace the melting zone is sealed off from the air and a pipe is connected to the bottom of the melt, which pipe reaches outside the furnace with its upper end to the height of the molten material inside the furnace. The casting mold is arranged on the top of the pipe. An atmosphere of protective gas is established above the surface of the molten material in the furnace; the pressure of the protective gas being controlled by a special equipment. Casting is accomplished by introducing the material to be molten through a gas lock and through the protective gas atmosphere into the melt, causing the pressure inside the furnace to increase and forcing the molten material through the rising pipe into the mold. After the mold is filled the pressure of the gas is increased in order to feed the shrinkage and to achieve a fine grained and dense casting.

摘要： This disclosure covers a process and mechanisms for controlling the temperature and heat balance of molds. More particularly, this invention relates to molds with built-in devices for heating and cooling various regions within molds. These devices are so constructed that each device is capable of heating and cooling independent of the other devices. The intensity of heating and cooling of these devices can be varied by regulating the flow of the heating/cooling medium in impulses for variable intervals of time. Prior to filling of the mold, the mold is heated to the desired working temperature by injecting a heated medium into the various heating/cooling devices. During or immediately after filling the mold, the flow of the heated medium to the device furthest from the casting riser (feeder) is discontinued and is replaced by a flow of cooling medium. When the material within the mold in the immediate vicinity of this device is solidified, the flow of cooling medium to this device is decreased or stopped. The remaining heating/cooling devices are then sequentially activated in the same manner as the first with activation occurring in a direction toward the casting riser. Thus, solidification is controlled in a directional manner so that it progresses from the region in the mold furthest from the casting riser toward the riser.
