METHOD FOR PRODUCING Cu-Ni-Sn ALLOY
The present invention provides a method for producing a Cu—Ni—Sn alloy, which achieves both productivity and product quality by reducing internal cracks and dispersing Sn uniformly while shortening the time for cooling an ingot. The method for producing a Cu—Ni—Sn alloy is a method for producing a Cu—Ni—Sn alloy by a continuous casting method or a semi-continuous casting method, the method including: pouring a molten Cu—Ni—Sn alloy from one end of a mold, both ends of which are open, and continuously drawing out the alloy as an ingot from the other end of the mold while solidifying a part of the alloy, the part being near the mold; performing primary cooling by spraying a liquid mist on the drawn-out ingot; and performing secondary cooling by immersing the ingot having been subjected to the primary cooling in a liquid, thereby making a cast product of the Cu—Ni—Sn alloy.
Method for producing Cu—Ni—Sn alloy and cooler to be used for same
There is provided a method for producing a Cu—Ni—Sn alloy by a continuous casting method or a semi-continuous casting method, the method including pouring a molten Cu—Ni—Sn alloy from one end of a mold, both ends of which are open, and continuously drawing out the alloy as an ingot from the other end of the mold while solidifying a part of the alloy, the part being near the mold; and spraying mist-like liquid on the drawn-out ingot to cool the ingot, thereby making a cast product of the Cu—Ni—Sn alloy.
Dynamically positioned diffuser for metal distribution during a casting operation
Provided herein are an apparatus and method for continuous casting of metal, and more particularly, to an apparatus and method to reduce macrosegregation through a mechanism for controlling the position of a spout tip or diffuser during the casting process to maintain the spout tip or diffuser near the solidification front, location of transition between liquid metal and solid metal in the cast part. An apparatus may include: a mold frame supporting a mold defining a mold cavity; a liquid diffuser; and an actuator configured to move at least one of the mold frame and the liquid diffuser relative to one another, wherein the actuator is configured to move at least one of the mold frame and the liquid diffuser relative to one another in response to a signal from at least one sensor.

SYSTEM, APPARATUS, AND METHOD FOR DIRECT CHILL CASTING VENTING
Provided herein is a system, apparatus, and method for venting a direct chill casting mold by venting excess casting gas and retaining oxide from atop a casting during the direct chill casting process. Methods of venting casting gas from a direct chill casting mold include: supplying the direct chill casting mold with molten metal through a transition plate; supplying a casting gas through a casting surface of the direct chill casting mold; venting the casting gas from a gas pocket in the transition plate, wherein venting the casting gas from the gas pocket in the transition plate is performed in response to a pressure of the casting gas in the gas pocket reaching a predetermined pressure.
