Description

Technical Field

[0001] This utility model relates to the field of continuous casting machine roller conveyor technology, and in particular to a roller conveyor device for straightening large billets. Background Technology

[0002] The roller conveyor of the large billet straightening machine in the special steel workshop is water-cooled. The roller conveyor adopts an integral structure with internal water-cooling channels that are cooled by circulating water. Hot steel billets are conveyed through the roller conveyor. When heated, the water-cooling channels inside the roller conveyor are prone to scaling and blockage, which reduces the cooling effect of the roller conveyor. Furthermore, due to thermal expansion and contraction, the weld seams of the roller conveyor section will crack as the hot steel billets are conveyed through the roller conveyor, resulting in water leakage. Moreover, once the internal water channels of the roller conveyor are blocked by scale, it cannot be repaired and must be scrapped and replaced, which reduces the service life of the roller conveyor.

[0003] Therefore, this utility model provides a roller conveyor device for straightening large billets. Utility Model Content
