Problems solved by technology

However, conventional couplings for roll lines are often worn due to overload caused by the difference in rotational speed between adjacent roll bodies and lead to breakage of the roll line and possibly serious impact on the slab

Embodiment Construction

[0064] The present invention will now be described more fully with reference to the accompanying drawings, in which presently preferred embodiments of the invention are shown. However, this invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and will fully convey the teachings of those skilled in the art scope of the invention.

[0065] The invention relates to a coupling device for an idler roll line in a continuous casting machine. The coupling device comprises at least a first part adapted to be arranged in connection with a first roller body of the idler line; and a second part adapted to be arranged in connection with a second roller body of the idler line. The first part and the second part are respectively rotatably movable about the central axis. The coupling device is switchable between a locked state allowing synchronou...

Abstract

The present invention relates to a coupling arrangement for an idler roll line in a continuous caster. The coupling arrangement comprises at least a first component adapted to be arranged in connection with a first roll body of the idler roll line and a second component adapted to be arranged in connection with a second roll body of the idler roll line. The first component and the second component, respectively, are rotatably moveable about a central axis. The coupling arrangement is switchable between a locking state, allowing for synchronized rotational motion of the first component and the second component about the central axis, and a releasing state, allowing for relative rotational motion between the first component and the second component about the central axis. The present invention also relates to an idler roll line comprising the coupling arrangement. The coupling arrangement allows for improved service life and reduced down-time.

Description

technical field [0001] The invention relates to the field of continuous casting of steel. The invention relates to a coupling device for an idler roll line in a continuous casting machine. The invention also relates to an idler line for a continuous casting machine comprising a coupling device. Background technique [0002] Continuous casting is a steelmaking method in which molten steel solidifies into semi-finished slabs for subsequent finishing in rolling mills. The molten steel solidifies and forms a semi-finished slab in a guide zone comprising upper and lower roll lines, which may be idler (non-driven) or driven roll lines. A roll line may comprise one or more rolling elements. Typically, the roll line includes a central water system for continuous cooling. [0003] Continuous casting is a matter of temperature (e.g. strand surface temperature typically in the range of 900 to 1100°C), high temperature variations, corrosion (e.g. due to external spray cooling and la...
