Example Embodiment

[0020] Example 1

[0021] Such as figure 2 As shown, a non-standard roller ring includes an annular roller ring body 1 and two roller grooves 3 arranged on the outer circumference of the roller ring body 1. The center of the roller ring body 1 is a hole for connecting with a shaft . The two roll grooves 3 have the same shape and are semi-circular. The width of the roll groove 3 is 39.3 mm. The rolling center distance of the rolling mill corresponding to the roll ring is 27.5 mm. When the roll ring is rolled, the groove 3 is The dimension of the billet 2 in the axial direction of the roll ring body 1 is 35.2 mm.

[0022] The calculation formula for the thickness of the non-standard roll ring is:

[0023] The thickness of the roll ring body 1 is H, the rolling center distance is Z, the pass width is W, and f is the correction coefficient, which satisfies

[0024] H=3Z+1 / 2W-f.

[0025] In the formula, the units of H, Z and W are millimeters, and f is selected according to the following...

Example Embodiment

[0032] Example 2

[0033] This embodiment aims at improving the problems of the original roll ring at the work station. The pre-finishing station of a high-speed wire mill originally used an eight-inch standard roll ring when rolling flat materials. The roll ring body 1 of this ring has an inner diameter of 126 mm, an outer diameter of 228.3 mm, and a thickness of 72 mm. If only one is opened The semi-elliptical roller groove 3 will cause a lot of waste, but the thickness of the roller ring body 1 is a standard size, and the width of the semi-elliptical roller groove 3 is larger than that of the semi-circular roller groove 3, so the roller ring body The thickness of 1 is not enough to open two semi-elliptical grooves 3. In order to reduce waste and make full use of the thickness of the roller ring body 1, the roller ring body 1 is opened like Figure 4 A semi-elliptical roller groove 3 and a semi-circular roller groove 3 are shown.

[0034] In actual production, the use rate of ...

Abstract

The invention discloses a non-standard roll collar. The non-standard roll collar comprises an annular roll collar body and two roll grooves formed in the outer circle of the roll collar body, and a hole used for being connected with a shaft is formed in the center of the roll collar body. The calculation formula of the thickness of the non-standard roll collar is that the rolling center distance is Z, the pass width is W, f is a correction coefficient, and H = 3Z + 1/2W-f. When one roller groove of the non-standard roll collar is abraded, the abraded roller groove can be detached, the non-standard roll collar can continuously produced by the other roller groove, so that the service life of the non-standard roll collar can be doubled, the purchase and grooving cost of the raw material is only increased by 45% compared with that of a roll collar with a single roller groove, the cost performance is very high, and the capital occupation of spare parts is reduced; and when the two roller grooves of the roll collar are abraded, the non-standard roll collar is detached, then the outer diameter of the roll collar body is ground to be small, and then the two roller grooves are ground to thesize before abrasion, therefore, the repair cost of the non-standard roll collar can be further reduced compared with that of a roll collar with a single roll groove.

Description

technical field [0001] The invention relates to the technical field of high-speed wire production equipment, in particular to a non-standard roller ring. Background technique [0002] Roll ring is one of the main consumables in high-speed wire production. After rough rolling, intermediate rolling, pre-finish rolling and finish rolling, the high-temperature billet passes through multiple pairs of roll rings in turn, and there are standard-sized roll grooves on the circumference of the roll rings. After rolling, the cross-sectional shape of the billet gradually changes from a rectangle to an ellipse, and finally to a circle. Due to the harsh working environment of the roller ring, the material performance requirements are extremely high. At present, the roll rings used in the pre-finishing and finishing rolling processes are made of tungsten carbide powder and binder through powder metallurgy technology under high temperature and high pressure conditions, and have the charac...
