In a manufacturing industry especially in steel and metal production rolling mills are critical in the formation process. However, similar to any other equipment, rolling mills tend to wear out due to time factor with focus on the rolls that are used to roll the actual product. One method of maintaining efficiency of rolling mills with a view of making sure that they continue to deliver quality products is called roll regrooving. This process can bring your rolling mills extra years of performance and improve work in the process.

 

What is Roll Regrooving?

Roll regrooving is a maintenance process that seeks to recreate the grooves on the roll surface found in many rolling mills. With time they get worn out by the regular pressure, heat and friction that comes with the rolling process. When the grooves are worn out, it results in mishandling of material, development of products with defects and high rates of equipment wear. Regrooving means the rolls are reshaped or deeper than they originally were to meet the needed performance and durability.

 

Why Roll Regrooving Is Essential?

In a rolling mill, the rolls are the main parts that bear the pressure that is needed to deform the materials and bring them to the right thickness and structure. These rolls also have grooved surface are necessary in helping to pick up the material and also in the movement of the material through the mill. As the rolls work then these grooves get worn out thus meaning that their grip is compromised and the efficiency of transfer of materials is also compromised. When this happens, you may notice several issues, including:

·       Uneven Material Flow: Such grooves get worn down resulting into inadequate distribution of pressure on the material and thus inadequately processed.

·       Increased Energy Consumption: Less effective grooves mean that in order to achieve such outcome the mill applies more force and therefore the energy and costs are higher.

·       Premature Wear on Other Parts: Worn rolls increase stress on other parts of the rolling mill so the system wears out at a much faster pace.

Roll regrooving is the answer to all these sayings Roll regrooving is simply the process of redistributing the layers of rubber on to the centreline of the tyre in order to get the tyres back to an as new state as possible. All the grooves flattened with time and using the process the rolls get back their full functionality and the mill does not have to put a lot of pressure on other parts because the rolls are in good working condition.

 

Benefits of Roll Regrooving

Extended Equipment Life: The biggest advantage or gain that can be derived from roll regrooving is actually an increase in the longevity of your rolls, and therefore the rolling mill. Through regrooving, you do not have to go for the rolls’ replacement which is very expensive for your business in the long run.

 

Improved Efficiency: Originally, grooves were formed on the surface of the rolls so they can grip or process the material and when these grooves become worn out or eroded, they have to be restored to be usable again. This results in an improved quality of the rolling mill’s products as well as a quantitative improvement to make the performance more reliable and efficient.

 

Cost-Effective Maintenance: In my research regrooving has already proved to be much cheaper in comparison to other more demanding solutions like new worn-out rolls. It provides you with an effective way to achieve high performance and save your mill from expensive premature roll replacements.

 

Reduced Downtime: Regrooving is relatively faster than having the whole roll replaced because it involves only dressing a new working surface on the roll. Therefore, roll regrooving reduces on time as production proceeds uninterrupted by long hours of halting.

 

Lower Maintenance Costs: Since you get to regroove your rolls often, it means that you are likely to do a minimal number of other maintenance checks that arise from a lot of wear down. This leads to a general reduction of the maintenance costs for the rolling mill companies.

 

When should Roll Regrooving be done?

The frequency of roll regrooving depends with the type of material processed, usage intensity and type of mill. Conventionally, often the rolls’ surface needs to be checked more frequently and, if the grooves get worn out, they should be re-cut again. This type of wear can be controlled by conducting regular monitoring and regrooving to avoid the problem aggravating or reaching the extent of seriously affecting the machine’s performance.

 

Conclusion

Roll regrooving is one of the crucial practices of maintaining your rolling mills so that its usage can be improved. Regrooving is therefore the enhancement of material handling, efficiency, reduction of energy utilization and overall cutting cost through the restoration of grooves on the rolls. In fact if you wish to keep your rolling mills profitable and efficient in the long run then roll regrooving is an expense that you cannot afford to be making sparingly.
