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.

An up-thawing continuous casting method includes drawing up molten metal (M1) held in a holding furnace (101), through a shape determining member (102) that determines a sectional shape of a cast casting (M3). The sectional shape determined by the shape determining member (102) includes a round-cornered portion, and a value (Rf) of a curvature radius of the round-cornered portion that is determined by the shape determining member (102) is smaller than a design value (Rt) of a curvature radius of a round-cornered portion of the casting (M3).

A twin roll casting system where the casting rolls have a nip between the casting rolls, each roller having a circumference and a rotational period. The casting roll controller adjusts the nip between the casting rolls in response to control signals. The sensor measures at least one parameter of the cast strip. The ILC controller receives strip measurement signals from the sensor and provides control signals to the casting roll controller. The ILC controller includes an ILC control algorithm to generate the control signals based on the strip measurement signals and a time delay estimate based on circumference, rotational period, and a length of cast strip between the nip and the sensor to compensate for an elapsed time from the cast strip exiting the nip to being measured by the cast strip sensor.

A strand casting installation in which a conicity of a die is set during a casting procedure by measuring temperature values along a centric measuring path running in a casting direction along an adjustably disposed die wall; measuring temperature values along a peripheral measuring path running in a casting direction along the adjustably disposed die wall, wherein the peripheral measuring path runs between the centric measuring path and a lateral periphery of the die wall, and a spacing of the peripheral measuring path from the lateral periphery of the die wall is smaller than a spacing of the centric measuring path from the other lateral periphery of the die wall; determining a centric temperature distribution curve along the centric measuring path from the temperature values measured along the centric measuring path; determining a peripheral temperature distribution curve along the peripheral measuring path from the temperature values measured along the peripheral measuring path; determining a first area under the centric temperature distribution curve, and a second area under the peripheral temperature distribution curve; determining a difference between the second area and the first area; and setting the conicity of the die taking into account the difference.

A method of controlling a continuous casting system for producing slabs from a material, the continuous casting system having a number of molds for forming corresponding strands, the method including receiving a plurality of casting orders, determining for each of the casting orders a set of slabs to be cast, sorting the slabs to be cast of the sets of the casting orders to obtain a sorted base sequence, uniformly partitioning the sorted base sequence into a number of subsequences, adjusting slab widths of the slabs to be cast of the subsequence, wherein, due to the adjustment, the width changes between two slabs to be cast immediately one after the other in the subsequence do not exceed a step value, wherein adjusted subsequences are obtained from the adjusted slab widths, transmitting control data to the continuous casting system for producing the slabs to be cast determined in the adjusted subsequences.

Apparatus and methods for casting a metal strip with a cross sectional form which varies along the length of the strip. One embodiment of the apparatus includes opposing cooling systems, a positionable molten metal feed system between the opposing cooling systems, and a form adjustment system. The form adjustment system may include at least one dam to determine, at least in part, the cross sectional form of a molten metal feed to the opposing cooling systems. In this way, it is possible to determine the cross sectional form of the solidified metal strip. The dam is moveable during operation of the apparatus to vary the cross sectional form of the molten metal feed to the opposing cooling systems.
