Provided herein is a system, apparatus, and method for providing casting gas to a direct chill casting mold, and more particularly, to supplying casting gas to a direct chill casting mold at a well-regulated pressure and volume using fluid injectors. Systems for supplying casting gas to a continuous casting mold can include: a continuous casting mold cavity; a casting gas supply line; an injector receiving casting gas from the casting gas supply line; and a post injector casting gas supply line, where the casting gas supply line provides casting gas at a pressure above 300 psi (pounds per square inch) to an input of the injector, where a controller controls the injector to supply casting gas via the post injector casting gas supply line to the continuous casting mold cavity.

Provided are aluminum 3xxx series alloy products having improved thermal and electrical stability, and methods for forming such products. Methods include DC casting a molten aluminum alloy, withdrawing the aluminum alloy from the mold to form an ingot, homogenizing the ingot at a homogenization temperature from 500 °C to 650 °C for a period of time from 1 to 5 hours. Methods include reducing the temperature to a soaking temperature from 350 °C to 550 °C and soaking the ingot for a period of time from 1 to 15 hours. Methods include hot rolling the homogenized ingot to produce a hot rolled aluminum alloy, and cold rolling the hot rolled aluminum alloy to produce to an aluminum alloy product.

Provided herein is a system, apparatus, and method for continuous casting of metal, and more particularly, to a mechanism for controlling the shape of a direct chill casting mold to dynamically control a profile of an ingot cast from the mold during the casting process. Embodiments may provide an apparatus for casting material including: first and second opposing side walls; first and second end walls extending between the first and second side walls, where the first and second opposing side walls and the first and second opposing end walls form a generally rectangular shaped mold cavity. At least one of the first and second opposing side walls may include two or more contact regions, where each of the two or more contact regions may be configured to be displaced relative to a straight line along the side wall.

A bottom block for use in direct chill (DC) casting that includes a flared base providing additional surface area for contact with coolant used in the DC casting process. The bottom block includes a first end that substantially fits within a DC mold while a second end has a larger cross-sectional area than the first end. A transition between the first end and the second end provides a surface for coolant to contact despite film boiling and air gaps between the ingot and the coolant.

A direct chill (DC) casting system may be used to cast a metal ingot from a molten metal such as aluminum or aluminum alloys. The DC casting system includes a steam condensation system that condenses steam generated during a DC casting process as recycled water. The recycled water may be used for subsequent cooling of the metal ingot during the DC casting process.

The invention discloses a low-carbon stainless steel evanescent mode direct casting process which solves the problem of low-carbon stainless steel direct casting. The process comprises the following steps: manufacturing a foamed plastic mold by using an aluminum mold according to design, and designing a pouring gate into a hollow conical shape; sTMMA is adopted for foaming to prepare a model piece, the model piece is dried, after assembly, the model piece is dip-coated with a special coating which is independently researched and developed and resistant to high temperature, high in air permeability and non-sticky to sand, and drying is conducted again; selecting ceramsite, and putting the model into a sand box for vibration molding; stainless steel is smelted, impurities are removed, pouring is conducted under negative pressure, the model is gasified, gas is discharged, and the cavity is filled with molten metal; shakeout and piece taking are conducted after pressure maintaining and cooling are conducted, and then surface shot blasting cleaning and hardness treatment are conducted; and finally detecting to ensure that the carbon content of the casting is lower than 0.07% and the casting leaves the factory after reaching the GB / T26658 quality evaluation standard. The process is low in cost and environment-friendly, and fills the blank in related fields.
