Straightening Roll for Seamless Tube Mill Cold Rolled

Product Description

Product Description

When the diameter of round steel increases, the amount of reverse bending required for straightening will inevitably decrease, so the bevel angle of the convex rollers also needs to be reduced, while the bevel angle of the concave rollers can be increased. The result of such angle adjustment will cause the round material to seriously deflect in the roll gap, causing serious unilateral wear of the roll gap guide plate. It can be seen that there is a considerable price to pay in order to expand the straightening range. When we try to reduce this effort, we can only reduce the convex roller bevel angle without increasing the concave roller bevel angle, and the deflection force will be reduced by half. If the concave roller also reduces the bevel angle synchronously with the convex roller, and the roller end does not produce obvious indentation on the surface of the round material, the straightening work can be carried out stably. However, diameter expansion of round materials is easy to occur after straightening. 2. When straightening thin round materials, it can be intuitively seen that the convex roller should increase the bevel angle, and the concave roller should reduce the bevel angle. The deviation phenomenon seriously exists in the opposite direction. At this time, neither straightening roller can change the bevel angle, let alone increase or decrease the bevel angle simultaneously. Generally, a certain diameter (d) is used as the standard when designing the roll shape. When straightening round materials with diameters d to 2d, the bevel angle of the convex roller can be reduced or the bevel angle of the concave roller can be kept unchanged or the concave roller can be appropriately reduced.
