ROLL LINE UNIT
20210187600 · 2021-06-24 ·

A roll line unit for a continuous casting apparatus includes a roll mantle or roll body surface rotatable relative to a support housing by means of bearing(s). The support housing has a seal(s) located axially outward relative to the at least one bearing and/or seal(s) located axially inward relative to the at least one bearing, and a lubrication system having lubricant reservoir(s) containing lubricant. The support housing has one or more cavities containing lubricant located adjacent to the seal disposed axially outward of the bearing(s) and/or the seal located axially inward of the bearing(s). The lubricant reservoir(s) is/are in fluid communication with the at least one cavity. An actuator within the lubricant reservoir(s) is arranged to move when the volume of lubricant increases in the cavity and/or the reservoir, and/or to push lubricant from the lubricant reservoir into the cavity when the amount of lubricant in the cavity decreases.

Method and device for producing foundry ingots from metal

The invention relates to a method for producing foundry ingots (1) from metal, in particular from steel, having a cross-sectional area of more than 0.1 m.sup.2, wherein liquid metal (2) is discharged into an ingot mold (15) open at the bottom either directly form a casting ladle (11) or via a tundish (12), and wherein, by a drawing piston (28), which is vertically movable in the direction of a longitudinal axis (5) of the foundry ingot (1) and on which the foundry ingot (1) is at least indirectly arranged, the at least partially solidified foundry ingot (1) is drawn from the ingot mold (15) in the direction of the longitudinal axis (5).

CONTINUOUS CASTING APPARATUS AND CORRESPONDING METHOD

Continuous casting apparatus comprising a plurality of compression units (11), each of which is defined by a lower roll (12) and an upper roll (13) configured to exert a compression action on a cast metal product (P). Each lower roll (12) defines with the respective upper roll (13) a passage gap (14) for the metal product (P). The passage gaps (14) of the compression units (11) are disposed aligned along a casting axis (Z) with an at least partly curved development. A straightening roll (15) is disposed on the extrados side of said casting axis (Z) and between at least two of the lower rolls (12).

CONTINUOUS CASTING METHOD OF STEEL

A continuous casting method of steel includes the step of bulging wide side surfaces of a slab having there inside an unsolidified layer with a total intentional bulging amount of 3 to 10 mm by increasing stepwise toward a downstream side in a casting direction a roller gap of a plurality of pairs of slab support rollers disposed in a continuous casting machine.

Vertical semi-continuous casting equipment and vertical semi-continuous casting method

Provided is vertical semi-continuous casting equipment including a guide device disposed under the mold to support the slab drawn from the plate, the guide device being configured to guide the descending of the slab. The guide device includes first and second guide parts including a plurality of guide rolls respectively disposed on both sides of a moving path of the plate under the mold to support the slab moving by the plate and guide the movement of the slab and a braking unit connected to each of the guide rolls to apply braking force to the guide roll that rotates by the movement of the slab. In accordance with an exemplary embodiment, the slab having the length longer than that of the slab in accordance with the related art may stably descend, the shaking of the slab may be prevented, and the casting speed may be stabilized.
