Abstract
The invention discloses a corrosion resistant and high wear resistant sink roll, which includes a cylindrical roll body and roll shafts connected to both ends of the roll body. The roll body includes an alloy sleeve, a metal ceramic sleeve and a hole sealing agent layer that are radially distributed from the inside out. The alloy sleeve is internally provided with a lead core. The further improvement lies in that the roll body surface is provided with a spiral groove, the bottom of which is in an arc shape. The sink roll provided by the invention has good corrosion resistance; change of gravity offsets part of tension, so that the support counterforce is diminished, the working area is expanded, damage to a sliding surface of the sink roll is significantly reduced, the wear resistance of the sink roll is significantly improved, and the production cost is reduced; and aluminum-zinc-iron alloy elements on the sink roll surface can be conveyed out through a spiral groove on the roll body surface, thus solving the nodulation problem on the roll surface and improving the product quality.
Description
Technical field
The present invention relates to the sinking roller on a kind of hot galvanizing line.
Background technology
Sinking roller is one of visual plant on hot galvanizing line, and sinking roller is subject to the corrosive nature of zinc liquid in process of production, under strip tension effect, is subject to larger frictional force effect, so be easy to occur sinking roller axle journal slipper wear damage simultaneously.The destruction of sinking roller is mainly the damage to sliding surface and the corrosive nature of zinc liquid due to support counter-force and kinetic friction torque.The sinking roller of prior art comprises columniform roll body, is connected to the roll shaft at roll body two ends, roll body comprises the matrix, alloy sheath, sintering metal cover, the hole sealing agent layer that radially distribute successively from inside to outside, the sinking roller of this structure is because weight is lighter, its gravity can not be offset partial tension, thereby the support counter-force producing is larger, larger to the damage of sinking roller sliding surface, the wearing no resistance of sinking roller, need often to change, increased production cost.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, a kind of anticorrosive, high abrasion sinking roller that significantly improves wear resistance is provided.
The present invention is achieved through the following technical solutions technical object.
Anticorrosive, high abrasion sinking roller, comprise columniform roll body, be connected to the roll shaft at roll body two ends; Described roll body comprises the alloy sheath, sintering metal cover, the hole sealing agent layer that radially distribute successively from inside to outside; Its improvements are: in described alloy sheath, be provided with lead for retractable pencil.
The present invention further improves and is: described roll body surface is provided with spiral slot.
Further improvement of the present invention is: described spiral fluted bottom is circular arc.
The present invention compared with prior art, has following positively effect:
1, in roll body, be provided with lead for retractable pencil, increase the weight of the weight of sinking roller, offset partial tension by the change of gravity, thereby dwindle support counter-force, expanded work area, significantly reduced the damage to sinking roller sliding surface, significantly improve the wear resistance of sinking roller, reduce production cost.
2, roll body skin is provided with sintering metal cover, hole sealing agent layer, can make sinking roller have good erosion resistance.
3, roll body surface is provided with spiral slot, the aluminium zinc-iron alloy element of sinking roller roll surface can be transferred out, and has solved roller surfaces and has formed dross problem, improves the quality of products.
4, spiral fluted bottom is circular arc, can obtain better conveying effect.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is the A-A diagrammatic cross-section in Fig. 1.
Fig. 3 is the local enlarged diagram of the I part in Fig. 1.
Embodiment
The invention will be further described with reference to the accompanying drawings and in conjunction with the embodiments below.
Anticorrosive, high abrasion sinking roller shown in the drawings, comprises columniform roll body 1, is connected to the roll shaft 2 at roll body 1 two ends; Roll body 1 comprises the alloy sheath 1.2, sintering metal cover 1.3, the hole sealing agent layer 1.4 that radially distribute successively from inside to outside; In alloy sheath 1.2, be provided with lead for retractable pencil 1.1.
In the present embodiment, roll body 1 surface is provided with spiral slot 3, forms dross problem to solve roller surfaces, improves the quality of products.
For obtaining better conveying effect, the bottom of spiral slot 3 is circular arc.
