Problems solved by technology
[0002] At present, the hearth rollers of the strip hot-dip galvanizing heating furnace are mostly cooled by water, and the roller body is cooled by feeding cooling water, but this also brings problems. First, the cooling water takes away a lot of heat during cooling, wasting fuel, and second. It consumes a lot of water and wastes water resources
However, the furnace hearth roller with this structure also has the following defects: the axial axial groove on the inner wall of the axial through hole in the roller body is difficult to manufacture, and the manufacturability is poor

Embodiment Construction
[0022] The present invention will be further described below according to the accompanying drawings and in conjunction with the embodiments.
[0023] The energy-saving water-cooled hearth roll shown in the accompanying drawings includes a roll body 1 and a roll shaft 2 connected to both ends of the roll body 1; the roll shaft 2 is inserted into the end of the roll body 1 to form a fit and fixed connection; the roll body 1 is provided with a shaft to the through hole; the roller shaft 2 at both ends is respectively provided with a water inlet and a water outlet connected with the axial through hole in the roller body 1; 3 is a sleeve-shaped member with an axial blind hole (in other embodiments, the elongated shaft 3 can be a solid shaft); the outer wall of the elongated shaft 3 is uniformly distributed with 18 axial ribs 3.2 in the circumferential direction, forming 18 axial ribs 3.2 Groove 3.1 (in other embodiments, there may be more or less than 18 axial ribs 3.2, or uneven d...

The invention discloses an energy-saving water-cooled furnace bottom roller. The energy-saving water-cooled furnace bottom roller comprises a roller body and roller shafts connected to the two ends of the roller body. The roller shafts are inserted into the ends of the roller body to be fixedly connected with the roller body in a matched mode. An axial through hole is formed in the roller body, a water inlet and a water outlet which are communicating with the axial through hole in the roller body are formed in the roller shafts at the two ends of the roller body correspondingly, and a thin and long shaft is inlaid in the axial through hole of the roller body. A plurality of axial rib strips are arranged on the outer wall of the thin and long shaft in the circumferential direction in a spaced mode, and a plurality of axial grooves are formed in the outer wall of the thin and long shaft in the circumferential direction in a spaced mode. According to further improvement, the axial rib strips are evenly distributed on the outer wall of the thin and long shaft and connected to the outer wall of the thin and long shaft in a welded mode; two positioning pin shafts which penetrate through the matched positions of the roller body and the roller shafts are arranged on the matched positions of the roller body and the roller shafts correspondingly, and the thin and long shaft is a shaft-sleeve-shaped component with an axial blind hole. The energy-saving water-cooled furnace bottom roller is high in structural strength and good in manufacturability, cooling water flows in an axial groove between the inner wall of the roller body and the thin and long shaft, heat brought away is little, fuel is saved, and water resources are remarkably saved.
Description
technical field [0001] The invention relates to the field of a strip hot-dip galvanizing heating furnace, and more specifically relates to a bottom roll of a strip hot-dip galvanizing heating furnace. Background technique [0002] At present, the hearth rollers of the strip hot-dip galvanizing heating furnace are mostly cooled by water, and the roller body is cooled by feeding cooling water, but this also brings problems. First, the cooling water takes away a lot of heat during cooling, wasting fuel, and second. It consumes a lot of water and wastes water resources. Chinese patent 201320158192.X discloses a "energy-saving spiral water-cooled hearth roller": a slender shaft is embedded in the axial through hole in the roller body, and an axial axial groove is provided on the inner wall of the axial through hole in the roller body, so that , when the hearth roll is in use, the cooling water flows in the axial groove between the inner wall of the roll and the slender shaft, an...
