An electromagnetic semi-continuous device comprises a crystallizer frame, an internal sleeve, a primary cooling water cavity, a secondary cooling water cavity and a tertiary cooling water cavity. An electromagnetic semi-continuous casting method comprises the steps of (1) adjusting angles of the adjustable spherical nozzles; (2) inserting a dummy bar head in a bottom of the internal sleeve; (3) feeding cooling water to the primary cooling water cavity and the secondary cooling water cavity, then spraying the cooling water to form primary cooling water and secondary cooling water, and exerting a magnetic field on the internal sleeve; (4) pouring the melts into the internal sleeve, starting the dummy bar head, and beginning to perform continuous casting; and (5) spraying tertiary cooling water through the tertiary cooling water cavity, so that casting billets reduce temperature until the continuous casting is completed.

The present disclosure relates to a system, apparatus, and method for a cooling water spray pattern for a direct chill casting mold, and more particularly, to a spiral water spray pattern for a direct chill billet casting mold. An example direct chill casting mold includes a mold body defining a mold cavity there through; and a plurality of spray jets arranged proximate an exit of the mold cavity, wherein the plurality of spray jets are angled with respect to the mold cavity such that streams of fluid exiting the plurality of spray jets impinge upon a casting exiting the mold cavity at an angle offset from a centerline of the casting.

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 continuous casting method or a semi-continuous casting method that includes 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.

The invention relates to a method and to a spraying apparatus (10) for the thermal surface treatment of a metal product (1). The metal product (1) is conveyed in a transport direction (T) through a treatment section (12) of a spraying apparatus (10) equipped with cooling nozzles (16) while cooling fluid is discharged through the cooling nozzles (16) of the spraying apparatus (10) onto the surfaces of the metal product (1), wherein the metal product (1) has—viewed in the transport direction (T) of the metal product (1)—a front section (4) and a trailing rear section (5). The cooling of the surfaces of the metal product (1) within the spraying apparatus (10) occurs in such a manner that the rear section (5) of the metal product (1) is cooled more significantly than its front section (4). It is thereby achieved that an essentially uniform ferrite content forms in the material of the metal product (1) at a predetermined depth of the same over a longitudinal area extending between the front section (4) and the rear section (5).

An electromagnetic stirring device and a method for a secondary cooling zone during slab continuous casting. The device has a main body, an opening adjustment assembly, and a secondary cooling assembly. The main body has a protection housing (3), a phase sequence control assembly, an iron core (4) and an electromagnetic coil (5) for carrying out variable-direction electromagnetic stirring on a molten steel by a three-phase current phase sequence transformation. The opening adjustment assembly has an air cylinder (7), a fixed base (8), a movable joint shaft (12) and a silicon steel sheet group insert (13) for adjusting online opening degree of the closed annular iron core by a movable joint structure. The secondary cooling assembly has a cooling water inlet (9) and a cooling water nozzle (10) for cooling the electromagnetic coil and spraying cooling water to a surface of a cast slab (1).

A crystallizer copper plate and a continuous casting crystallizer. The crystallizer copper plate is provided with a metal continuous casting die surface and a rear-side cooling fixed surface. The fixed surface is provided with fixing screw holes in a vertical column connected to a fixed water tank or an adapter backplate and mesas forming the surrounding of the screw holes. Reinforced bars are connected between multiple mesas of each column. Cooling channels lower than the fixed surface are provided between any two adjacent two columns of fixing screw holes. Flow-diverting cooling bars are provided at the middle of meniscus regions of the cooling channels. Either the top end or the bottom end of the flow-diverting cooling bar is a cone used for altering the direction of movement of a cooling medium.

A device for producing hot-rolled metal strips has a casting machine that produces and transports slabs in a transport line of the casting machine. A rolling mill forms the slabs into corresponding metal strips during transport along a transport line of the rolling mill. A combination transport and temperature-influencing device is arranged between the casting machine and the rolling mill transports the slabs at least along the transport line of the rolling mill, feeds the slabs to the rolling mill and sets the temperature of the slabs to a rolling temperature. A surface device is arranged between the casting machine and the combination transport and temperature-influencing device and processes and/or treats and/or inspects at least one of the surfaces of the slabs. A temperature-influencing device is arranged between the casting machine and the combination transport and temperature-influencing device and modifies the temperature of the slabs.
