Abstract
The utility model provides a pinch roll capable of restraining uneven thickness of a self-fusion alloy meltallizing coating film. The main body (7) of the pinch roll (100) is cylindrical, the wall thickness of the main body is 80-150 mm, and the thickness of the self-fusion alloy meltallizing coating film on the surface of the main body is at least 1.0 mm. Due to the fact that the wall thickness of the main body is more than 80 mm, the strength of the main body can be ensured, and a reinforcing plate on the main body is of no need. Due to the fact that the reinforcing plate is not mounted on the main body, uneven deformation of the main body and uneven thickness of the self-fusion alloy meltallizing coating film in fusion processing can be restrained. Accordingly, when the thickness (average thickness) of the self-fusion alloy meltallizing coating film is as usual and within the range of 1.5-3.0 mm, even the thinnest portion is more than 1.0 mm in thickness, so that adequate abrasion resistance of the main body is ensured. The wall thickness of the main body is smaller than 150 mm, so that manufacturing cost is restrained.

Utility model content
But, for top pinch roll 1 in the past, the position of reinforcement plate and the position that reinforcement plate is not installed being installed, the main part deformation quantity that the heat during because of melt process causes can be different, therefore, are formed at plated film in uneven thickness on main part surface.Therefore, in top pinch roll 1 in the past, there are the following problems, when the thickness that the self-dissolving alloy meltallizing plated film at the position of reinforcement plate is installed is 1.5～3.0mm, the thickness at position of reinforcement plate is not installed for below 0.5mm.
The purpose of this utility model is to provide a kind of pinch roll in uneven thickness that can suppress self-dissolving alloy meltallizing plated film.
Pinch roll of the present utility model is the pinch roll of steel plate being delivered to coiling pusher side, it is characterized in that, the main part contacting with steel plate is that tubular and wall thickness are 80mm～150mm; The surface of described main part has self-dissolving alloy meltallizing plated film, more than the thickness of described self-dissolving alloy meltallizing plated film is at least 1.0mm.
The utility model is more than 80mm owing to making the wall thickness of main part, the thermal deformation therefore can suppress melt process time and the distortion by the main part bringing from the impact of steel plate, and at main part, reinforcement plate is not installed.And in the utility model, owing to reinforcement plate not being installed at main part, therefore, can suppress melt process time, the deformation quantity of main part is inhomogeneous, and then can suppress the in uneven thickness of self-dissolving alloy meltallizing plated film.Thus, in the utility model, self-dissolving alloy meltallizing plated film is formed as and conventionally identical thickness (average thickness), while being the scope of 1.5～3.0mm, even at the thinnest position of thickness, it is more than 1.0mm also making thickness,, can make more than thickness is at least 1.0mm.Therefore,, in the utility model, can guarantee the sufficient wearability of main part.In addition, in the utility model, be below 150mm owing to making the wall thickness of main part, therefore can suppress manufacturing cost.
Preferred pinch roll of the present utility model comprises: axle; 1st, the 2nd wheel hub, it radially extends in outside from described axle; And as the barrel-type casing of described main part, its axial both ends are connected with described the 1st, the 2nd wheel hub; The described axially part between the above the 1st, the 2nd wheel hub of the inner peripheral surface of described housing is positioned at the same face.
Preferred pinch roll of the present utility model is the top pinch roll that is positioned at top in opposed pinch roll.

Detailed description of the invention
Referring to accompanying drawing, embodiment of the present utility model is described.
Figure l is the schematic cross-section of top pinch roll 100.
As mentioned above, top pinch roll 100 is used as steel plate to deliver to the roller of coiling pusher side in hot rolling workshop winding apparatus, is positioned at opposed bottom pinch roll 2(Fig. 4) top.Top pinch roll 100 comprises axle 6, housing 7 and the 1st, the 2nd wheel hub 81,82.
1st, the 2nd wheel hub 81,82 is endless member, at position embedded axle 6 away from each other.1st, the 2nd wheel hub 81,82 radially extends in outside from axle 6.
Housing 7 is the main part contacting with steel plate in top pinch roll 100.Housing 7 is cylindrical shape, chimeric with the 1st, the 2nd wheel hub 81,82, and its axial both ends and the 1st, the 2nd wheel hub 81,82 connect.Part between axial upper the 1st, the 2nd wheel hub 81,82 of the inner peripheral surface of housing 7 is positioned at the same face., present embodiment, from the past different, is not installed reinforcement plate at the inner peripheral surface of housing 7.
The wall thickness of the housing 7 of present embodiment is 80～150mm, is greater than wall thickness 70mm in the past.In the present embodiment, be 80mm by the wall thickness that makes housing 7, be greater than thickness in the past, can suppress melt process time there is thermal deformation in housing 7, and can suppress to impact by the steel plate moving through the housing 7 bringing and be out of shape, and at housing 7, reinforcement plate is not installed.In the present embodiment, be below 150mm by making the wall thickness of housing 7, can suppress manufacturing cost.
Fig. 2 is the cross section enlarged drawing of the skin section of housing 7.
On the mother metal of housing 7, there is substrate hardening built-up welding layer 71 and be laminated to the self-dissolving alloy meltallizing plated film 72 of substrate hardening built-up welding layer 71.
Substrate hardening built-up welding layer 71 is by using known welding material, carries out built-up welding and forms.Substrate hardening built-up welding layer 71 can make housing 7 have recessed distortion, the patience of bending strain etc. on anti-housing 7 surfaces.
As mentioned above, form self-dissolving alloy meltallizing plated film 72 by the plated film being formed by self-dissolving alloy being carried out to melt process.The thickness (average thickness) of self-dissolving alloy meltallizing plated film 72 is preferably the scope of 1.5～3.0mm.In the present embodiment, due to from the past different, at housing 7, reinforcement plate is not installed, therefore, can suppress melt process time, the deformation quantity of housing 7 is inhomogeneous, and then can suppress to cause self-dissolving alloy meltallizing plated film 72 in uneven thickness because of melt process.
Therefore, in the present embodiment, by the thickness that self-dissolving alloy meltallizing plated film 72 is formed as more than 1.5mm, even at the thinnest position of thickness, also it is more than 1.0mm can making the thickness of self-dissolving alloy meltallizing plated film 72, and the coating film thickness that can guarantee the main part entirety of top pinch roll 100 is more than 1.0mm.Due to, in the present embodiment, can make the main part of top pinch roll 100 there is sufficient wearability.In addition, in the present embodiment, because the thickness that makes self-dissolving alloy meltallizing plated film 72 is below 3.0mm, therefore can suppress manufacturing cost.
In said embodiment, the 1st, the 2nd wheel hub 81,82 and not one of axle 6, still, and also can be as shown in Figure 3, make the 1st, the 2nd wheel hub 81A, 82A and axle 6A are integrated.
As application examples of the present utility model, top pinch roll 100 has been described in the above-described embodiment, still, the utility model also goes for bottom pinch roll 2(Fig. 4).In addition, in the above-described embodiment, the axle 6A at two ends is connected, and still, the utility model is not limited thereto.For example, the axle 6A at two ends can be also absolute construction separated from one another.Now, form blank part at the radially inner side of housing 7, because top pinch roll 100A is easily to radially bending, therefore, can improve flexibility.
