The working condition and some basic conditions of annealing furnace roller

Date of release:2019-04-24 Author: Click:

The working condition of roller is the most complicated.The residual stress and thermal stress will be generated in the preparation process before the roll is manufactured and used.It is further affected by various periodic stresses, including bending, torsion, shear, contact stress and thermal stress.The distribution of these forces along the roller body is uneven and changing, which is caused not only by design factors, but also by the wear of the roller in use, the constant change of temperature and roll shape.



In addition, roll conditions often appear abnormal.Improper cooling of rollers after use will also be damaged by thermal stress.So roll in addition to wear, also often appear cracks, fracture, peeling, indentation and other local damage and surface damage.A good roll, its strength, wear resistance and other performance indicators should be a better match.

Residual stress and thermal stress will occur in the preparation process of annealing furnace roll before production and application.When applied, it is further affected by various periodic stresses, including tortuous, change, shear, contact stress and thermal stress.The distribution of these stresses along the roll body is uneven and constantly changing, due not only to the planning elements, but also to the wear of the roll in use, the constant change of temperature and roll shape.In addition, rolling conditions often appear abnormal.Improper cooling of rollers after use will also be harmed by thermal stress.So roll in addition to wear, but also often appear cracks, fracture, peeling, indentation and other partial damage and appearance damage.A good roll, its strength, wear resistance and other performance indicators should be a better match.In this way, not only under normal rolling conditions of durability, and can show some abnormal rolling conditions when the damage is less.Therefore, the metallurgical quality of rollers should be strictly controlled or supplemented by external measures to enhance the bearing capacity of rollers.

There are many kinds of rolling mills for producing long material products. Therefore, the selection and layout of rolling mills, the selection of roll material and the determination of roll size are also very wide.At the same time, different rolling mill roll choice is not the same, according to the production requirements of the choice of roll.
