A bearing seat assembly for a roller assembly includes a bearing seat; a bearing, arranged inside the bearing seat; a first seal, including at least two sealing lips. The first seal is installed on the bearing seat and is arranged on a first axial outer side of the bearing. At least one sealing lip of the at least two sealing lips of the first seal is arranged around the inner or outer circumference of the first seal. The bearing seat assembly according to the present disclosure realizes enhanced sealing, avoids re-lubrication, improves thermal performance, and prolongs service life.

Bearing seat assembly

A method for manufacturing a roll mantle or roll body for a roll line of a continuous casting apparatus that has a shaft includes casting a metal to form the roll mantle or roll body such that the roll mantle or roll body includes at least one internal channel. The roll mantle or roll body has a first end region, a second end region and a central region between the first end region and the second end region, the central region extending along at least 50% of a length of the roll mantle or roll body, and the internal channel may be formed in the central region. The internal channel may also include a pattern or projection.

Method of forming a roll body or roll mantle

A roll line unit for a continuous casting apparatus includes a roll mantle having two ends and a non-rotatable shaft including a coolant line. The roll mantle is rotatably mounted on the non-rotatable shaft by means of a first bearing located in a first end region of the roll mantle and a second bearing located in a second end region of the roll mantle. The roll mantle includes at least one coolant channel having at least one fluid inlet that is arranged to be in fluid communication with the coolant line. The roll line unit includes two outer seals located on an axially outward side of each of the first and second bearings, whereby the outer seals and the first and second bearings are located axially inwards of the ends of the roll mantle.

Roll line unit and continuous casting apparatus

A roll mantle or roll body configured to be mounted on a shaft of a roll line of a continuous casting apparatus, the roll mantle or roll body being formed by casting and having at least one internal channel. The roll mantle or roll body has a first end region, a second end region and a central region in between the first end region, and the second end region extends along at least 50% of the length of the roll mantle or roll body. The at least one internal channel may be located in the central region and may include a feature such as a pattern or projection.

Roll mantle, roll body and method of forming same

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.

Roll line unit

A seal cassette for a roll line in a continuous casting machine. The seal cassette configured to seal off a space from an outside environment and includes a first circumferential element and a second circumferential element arranged coaxially and rotatably movable relative each other. At least one third circumferential element is provided and is arranged coaxially relative the first and the second circumferential element and further arranged to be rotatably movable relative the second circumferential element. The first circumferential element is formed as a sleeve extending in an axial direction (A). The second circumferential element provides at least one circumferential seal portion arranged to seal between the second element and the first element. The at least one third circumferential element provides at least one circumferential seal portion to seal between the third element and the second element and further provides a circumferential seal portion that seals against the first element.
