A production apparatus for short-process metal composite plate manufacturing, comprising a metal supply device including an uncoiler (1), pinch roll (2), shot blasting machine (3), welding device (4), welding pinch roll (5), induction heating apparatus (6), metal delivery machine (7), two crystallization cooling rolls (8), secondary cooling leveling roll (9), rolling mill pinch roll (10), rolling mill (11), on-line cooling apparatus (12), straightener (13), and at least one of a dividing shear (14) and a recoiling machine (15). Also disclosed is a production method for short-process metal composite plate manufacturing. The apparatus and method combine continuous casting, rolling, and heat-treating means for single material production with continuous and large-scale production of composite plate strips, and production efficiency of composite plates is sharply improved. Single-sided or double-sided composite plate production having different thickness specifications can be performed, the optional range of a base layer or cladding material is wide.

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.

A method of manufacturing a mold includes the processes of: arranging a channel member in a recessed groove formed on a surface of a mold body; irradiating an opening part of the recessed groove with a first laser, thereby performing a first build-up welding on a part in the vicinity of the opening part of the recessed groove; and irradiating a region on a surface of the mold body including a region where the first build-up welding has been performed with a second laser, thereby performing a second build-up welding on a region on the surface of the mold body including the region where the first build-up welding has been performed.

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.

What is provided is a secondary cooling device for continuous casting that is configured to cool a slab, which is sent in a casting direction, by spraying cooling water to the slab surface. The secondary cooling device for continuous casting includes a plurality of rolls disposed side by side in the vertical direction along a casting direction and a spray nozzle configured to spray the cooling water to the slab surface from between the plurality of rolls. The spray nozzle is provided such that the cooling water spray axis of the spray nozzle is inclined with respect to the major axis direction of a spray range of the cooling water on the slab surface, the major axis of the spray range is rotated upward around an axis line that is a perpendicular line to the slab surface from the spray nozzle, and the center of the spray range is positioned above a middle position between a contact position between the roll that is present above the spray nozzle and the slab surface and a contact position between the roll that is present below the spray nozzle and the slab surface.

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.

A crack-free continuous casting mold configured so that occurrence of cracks at a casting billet can be reduced even in a case where a casting speed exceeds 500 mm/min. The continuous casting mold continuously casts a casting billet while cooling molten metal by a cooling device provided at a cooling casting mold. The cooling device includes multiple cooling nozzles configured to release coolant water to the casting billet pulled out of the cooling casting mold to cool the casting billet. Multiple ejection ports of the multiple cooling nozzles are arranged along an outer circumferential direction of a surface of the casting billet. Each ejection port has a short side and a long side, and is configured such that the long side is arranged along an axial direction of the casting billet.
