KOCKS Cemented Carbide Roll Rings

Product Introduct：

KOCKS Cemented Carbide Roll Rings for KOCKS three-roll mill to replace the original ball-milling of cast iron roll ringmainly the production of bearing steel, spring steel, alloy steel and other special steel, steel surface and tolerance controls are clearly better than cast iron roll ring and wear-resistant is good, life is a cast iron roll ring 10 times.

Three dimensional carbide rolls tor cold rolling ot ribbed steel bars

The steel reinforcement rolled by three dimensional carbide rolls has fine appearance surface high precision in dimension and clear ribbed mark. Those improved the comprehensive properties of ribbed steel reinforcements. The primary rolling tonnage are 600-2000 tons. which is 20-30 times more than that of common tool steel rolls. Because cemented carbide rolls can be reground and used again, the production cost is reduced greatly. That markedly improved productive efficiency and profit.

Development Background and Application

Development Target: This is a new material specially developed for roller rings.

Applicable Equipment and Scenarios: It is designed for the KOCKS three-roll reduction and sizing rolling mill, mainly used for the production of special steel bars.

Hardness and Physical Properties

Hardness Indicators: The material hardness is HRC 60–63; the uniformity of roller surface hardness is ≤ 1.5 HRC (the hardness difference is very small).

Wear Resistance and Toughness: It combines high wear resistance and high impact toughness under thermal load.

Anti-Bursting Advantage: Compared to hard alloy, it is less likely to cause ring bursting. This advantage is especially obvious when rolling large-sized bars of φ20 or above.

Single Grinding Amount: The single grinding amount (reduction in diameter) is ≤ 0.8 mm.

Processing Performance

It has good processing performance and can be machined on a CNC lathe with high efficiency.

This helps reduce the frequency of roller replacements.

Usage Effects and Economic Benefits

Steel Passing Volume: The total steel passing volume of each group of roller rings reaches more than 80% of that of hard alloy roller rings, and is more than 25% higher than that of domestic similar products.

Cost-Performance Ratio: It has a very high cost-performance advantage.

Application Recommendation: It is very suitable for the rolling of large-sized special steel bars with a diameter of φ20 or above.
