Vacuum pressure transformation vessel and method of use

A method of forming a ceramic-metal composite part is described herein. The method includes maintaining molten metal in an interior of a housing in a liquefied state, the interior including a first chamber, a second chamber, and a port defined therebetween. The method further includes sealing the port such that the molten metal in the first chamber is maintained at a first liquid level, suspending a part at a height within the first chamber above the first liquid level, forming a pressure differential between the first chamber and the second chamber, unsealing the port such that molten metal from the second chamber flows into the first chamber, and resealing the port when the molten metal in the first chamber reaches a second liquid level such that the ceramic part is submerged in the molten metal.

Transfer system with dual-flow rotor

The invention relates to systems for transferring molten metal from one structure to another. Aspects of the invention include a transfer chamber constructed inside of or next to a vessel used to retain molten metal. The transfer chamber is in fluid communication with the vessel so molten metal from the vessel can enter the transfer chamber. A powered device, which may be inside of the transfer chamber, moves molten metal upward and out of the transfer chamber and preferably into a structure outside of the vessel, such as another vessel or a launder.

Transfer vessel with dividing wall

A method for transferring molten metal from one structure to another includes a cavity constructed inside of or next to a vessel used to retain molten metal. The cavity is divided into a first section and a second section by a wall, wherein the second section includes an uptake section configured to allow molten metal to move upwards, and includes a molten metal pump. The cavity is in fluid communication with the vessel so molten metal from the vessel can enter the cavity through an opening. The pump is operated to move molten metal up upwards in the intake section and through an outlet.

20210187603 · 2021-06-24 ·

A casting device of a large non-ferrous metal thin-walled structural component. A liquid outlet of the casting device is communicated with a casting sand box. The casting device comprises an L-shaped liquid storage cylinder, a pressure supplying cylinder, and a crystallization treater. Protective gas with the first gas pressure can be inflated into the top of the L-shaped liquid storage cylinder. The pressure supplying cylinder and the L-shaped liquid storage cylinder are integrally connected to form a U-shaped tube connector. Protective gas with the second gas pressure can be inflated into the top of the pressure supplying cylinder. A liquid inlet of the crystallization treater is communicated with the pressure supplying cylinder while a liquid outlet is communicated with the pouring system and the mold cavity. The crystallization treater is provided with a grain refining mechanism.
