HSS roll ring is a new product that we specially developed for KOCKS mill bar production line.
Good Wear Resistance
Strong Impact Resistance
Better Surface Finish
Increase the rate of finished products
High operation rate
lower production cost
Reduce subsequent processing costs
It has excellent wear-resistant and shock-proof performance under thermal load with hardness HSD81-87. It will not burst in the rolling progress. It can be processed by CNC lathe machine with high processing efficiency and low cost.
The quantity of steel rolling can be up to 70-80% of cemented carbide roll ring and its price is less than a half of cemented carbide roll ring. So it’s the good choice as the replace plan for the nodular cast iron ring and the TC rings.
It can be used for producing pipe, rod and bar.
The single grinding amount of the roll is less than 1mm. This type of roll is used in finishing applications for increased campaign times and better surface finish.
The spread of 3-roll pass is only one fifth of that of 2-roll pass.
Moreover, the 3-roll pass has good sizing ability even at higher deformation.
The groove wear of three roll pass is smaller, and the cost of roll and guide is reduced by about 30%.
The surface quality of the finished bar is better by three-roll rolling.
- High durability and wear resistance: HSS roll rings are known for their high level of hardness, which results in greater durability and wear resistance. They can withstand the demanding conditions of the KOCKS bar mills and maintain their performance over time.
- Improved productivity: With HSS roll rings, the KOCKS bar mills can achieve higher speeds and feed rates, leading to improved productivity. The reduced downtime for roll changes also contributes to increased productivity.
- Enhanced product quality: HSS roll rings offer superior surface finish, dimensional accuracy, and consistency, leading to high-quality end products. The roll rings’ improved wear resistance also helps maintain the required tolerances over an extended period, ensuring consistent product quality.
