The roll grinding process in the steel industry is performed to recondition work rolls or backup rolls according to specified requirements. This process requires a coolant that functions as both a coolant and a lubricant between the roll and the grinding wheel.

Back up roll and work roll 

Issues

In the roll grinding process, there are several common issues encountered in the field related to the use of coolant, such as:

• Excessive coolant consumption
• Short lifespan of the grinding wheel
• Surface roughness not achieved
• Rust on the roll after the grinding process
• Operator irritation
• Large amounts of waste

A steel industry company once faced these issues and gave Eonchemicals the opportunity to provide a solution.

Solution

After gathering sufficient data, Eonchemicals offered the EonTrim C115 coolant product to address the aforementioned issues. A trial was conducted to monitor the performance of EonTrim C115 compared to the previously used coolant (existing).

Trial Results

Adapun data yang dihasilkan selama periode trial adalah sebagai berikut: 

Parameter	Existing	EonTrim C115
Konsumsi coolant (Kg/roll)	1.64	1.32
Konsumsi batu gerinda (mm/roll)	0.51	0.23
Kehalusan (roughness)	Problem	Perform
Karat	< 1 day	> 1 day
Iritasi pada operator	Yes	No
Lifetime coolant	3 months	> 1 year

The above data show that the use of EonTrim C115 coolant successfully:

• Reduced coolant consumption by 20%
• Reduced grinding wheel consumption by 55%
• Reduced waste due to significantly longer lifetime
• Saved labor, as it does not need to be drained frequently

Given the highly satisfactory trial results, the EonTrim C115 coolant product was deemed to meet expectations and suitable for use. This product has been used by the company for over 10 years to assist in the roll grinding process.
