Device to separate water and solids of spray water in a continuous caster, and method to monitor and control corrosion background
A system and methods are disclosed for treating cooling fluid in a continuous metal casting process having a spray chamber. In some embodiments, the system includes a first compartment with an intermittently operable outlet (e.g., valve) with an open state and a closed state, for removing particulate matter, and a second compartment that receives particle-free fluid from the first compartment. The first compartment may be tapered, conical, funnel, pyramidal shape or otherwise narrowed shape to facilitate settling of the particles. One or more sensors measure at least one property of the particle-free fluid to determine the opened or closed state of the outlet and to adjust chemical additives for the cooling fluid. In some embodiments, the system and methods reduce corrosion in spray chambers.

COOLANT NOZZLE FOR COOLING A METAL STRAND IN A CONTINUOUS CASTING INSTALLATION
A coolant nozzle (1) for cooling a metal strand in a continuous casting installation has a mouthpiece (5), which is arranged at a nozzle outlet end (4) and through which liquid coolant (6) can emerge from the coolant nozzle (1). To allow a rapid buildup of pressure at the coolant nozzle (1), it provides a feed (8), which is formed as a tube-in-tube system (9) arranged upstream of the mouthpiece (5) in the direction of through-flow (7) and has a feed outlet end (10), through the first tube (11) in which control air (13) can be brought up to the feed outlet end (10) and through the second tube (12) of which the liquid coolant (6) can be fed to the mouthpiece (5) by way of the feed outlet end (10), and also provides a control valve (14), which is integrated in the feed (8), is arranged at the feed outlet end (10), can be actuated pneumatically by using the control air (13) and is intended for controlling the feed of the liquid coolant (6) into the mouthpiece (5).
Amorphous alloy ribbon and method of producing the same
The invention provides a method of producing an amorphous alloy ribbon, the method including a step of producing an amorphous alloy ribbon by discharging a molten alloy through a rectangular opening of a molten metal nozzle having a molten metal flow channel along which the molten alloy flows, the opening being an end of the molten metal flow channel, onto a surface of a rotating chill roll, in which, among wall surfaces of the molten metal flow channel, a maximum height Rz(t) of a surface t, which is a wall surface parallel to a flow direction of the molten alloy and to a short side direction of the opening, is 10.5 m or less.

COOLING PAD ASSEMBLY FOR A BELT CASTING SYSTEM
A cooling pad for a belt casting system includes a first nozzle arrangement and a second nozzle arrangement. In some embodiments, the first nozzle arrangement includes an elongated nozzle assembly that includes a base defining a receiving area, a first insert positionable within the receiving area, and a second insert positionable within the receiving area. The first insert and the base together define a first elongated dispensing slot. The second insert is adjustable relative to the first insert, and the second insert and the base together define a second elongated dispensing slot. In various embodiments, the second nozzle arrangement includes a plurality of multi-position nozzles, each movable between a base position and an offset position such that the heat transfer rate may be locally controlled across the cooling cavity.

CONTINUOUS CASTING APPARATUS FOR METAL AND CONTINUOUS CASTING METHOD
A continuous casting apparatus for metal is provided. A refrigerant is ejected from ejection ports arranged on an outer side of an outer periphery of an ingot to cool the ingot that continuously passes through a mold and solidifies. When an axis connecting the ejection port and an axis of the ingot is denoted as a projection reference axis as viewed in a direction of the axis of the ingot, the ejection port is configured such that an ejection direction of the refrigerant ejected from the ejection port is inclined in one direction with reference to the projection reference axis so that the ejection direction of the refrigerant do not intersect with the axis of the ingot.
