Problems solved by technology

[0002] Since the rollers operate at high temperatures and due to their length, they are usually divided into sections with one or more pieces similar to piece 4 (see figure 2 ) non-locating bearing support, but because these non-locating bearings in the middle are directly exposed to high-temperature casting slabs and withstand high-temperature radiation, it is required to have a water-cooling system to maintain its normal operation. Such a structure not only causes equipment manufacturing and maintenance costs High, and because the roll surface of the roll is discontinuous, the surface quality of the slab is affected to a certain extent

Embodiment Construction

[0011] The invention will be further illustrated below with reference to a non-limiting embodiment disclosed in the accompanying drawings.

[0012] The names of the parts in the accompanying drawings are: continuous casting roll 1, support roller 2, positioning bearing 3, non-locating bearing support 4, frame 5, sliding bearing 6, bearing seat 7. Crystallizer A, nozzle B, liquid core C, continuous casting slab D.

[0013] figure 1 is a schematic diagram of a typical part of a continuous casting machine roll set, each pair of rolls of the roll set guides and supports a continuous casting slab D having a more or less liquid core at the top and upper part (ie Liquid core C), but the liquid core will solidify with cooling during continuous feeding in the direction indicated by the arrow.

[0014] figure 2 and image 3 The part shown includes a continuous casting roll 1 with a single roll surface and water cooling holes inside, a support composed of a positioning bearing 3, a ...

Abstract

The invention relates to a carrier roller support device for the rolling part of a continuous caster, consisting of a positioning bearing (3) and a non-positioning bearing support (4), which is characterized in that at least a support carrier roller (2) is used for supporting a continuous cast rolling part (1); the support carrier roller (2) is limited inside a cylindrical self-lubricating slide bearing (6) with the size larger than four fifth of a circle to realize the circumferential rotation; the slide bearing (6) is arranged inside and fixed with a bearing seat (7) through a bolt or a pin bolt; meanwhile, the bearing seat (7) is connected with a sector frame (5) of the caster.

Description

technical field [0001] The invention relates to a support roller design for continuous casting machine rolls. Background technique [0002] Since the rollers operate at high temperatures and due to their length, they are usually divided into sections with one or more pieces similar to piece 4 (see figure 2 ) non-locating bearing support, but because these non-locating bearings in the middle are directly exposed to high-temperature casting slabs and withstand high-temperature radiation, it is required to have a water-cooling system to maintain its normal operation. Such a structure not only causes equipment manufacturing and maintenance costs High, and because the roller surface is a discontinuous roller surface, the surface quality of the slab is affected to a certain extent. Invention content: [0003] The object of the present invention is to provide an idler support device for continuous casting machine roll parts which avoids the above problems, and it has the advanta...
