HR40 Tungsten Carbide Pre Finishing Ring Roller Cemented Carbide Hot Rolling Block
Our company independently developed carbide grades HR30 HR40 HR45 for hot rolling rollers: with high temperature resistance, high pressure resistance, high hardness, high wear resistance, efficient production and high economic benefits. The specific performance is as follows:
Tungsten Carbide Hot Rolling Ring HR30
Carbide rollers, also known as tungsten carbide rollers, have superior performance, stable quality, high product processing precision, good wear resistance and high impact resistance. Carbide rollers are made of tungsten carbide, cobalt, nickel and other materials using powder metallurgy. Carbide rollers are available in two types: integral and combined.
15% Binder Turkey Market Tungsten Carbide Ring Roll PR4.5
Tungsten carbide rollers are available in both integral and combined versions. They have excellent performance, stable quality, high processing precision, good wear resistance, and high impact resistance. The tungsten cemented carbide rollers have high hardness, and its hardness changes very little with temperature changes.
Tungsten Carbide Forming Roll 150*90*15mm FO3 For TMT Bar Rolling Mill
In a cold rolling mill, the metal is fed through a series of rolls, which gradually reduce its thickness. The rolls exert pressure on the material, causing it to deform plastically and elongate. To ensure uniform thickness reduction, the material may pass through multiple stands, each with progressively smaller roll gaps. The rolls in a cold rolling mill are typically made of hardened steel or tungsten carbide to withstand the high pressures and friction involved in the process.
TC roller are highly efficient and durable due to the exceptional hardness and wear resistance of tungsten carbide. Tungsten carbide is a composite material made of tungsten carbide particles (hard phase) embedded in a metal matrix (binder phase), typically cobalt or nickel. This combination results in a material with excellent hardness, strength, and resistance to wear and deformation.
The tungsten carbide cold rollers are designed to withstand the high compressive forces and abrasion encountered during cold rolling operations. They are typically used for rolling various types of materials such as steel, aluminum, copper, and alloys. The precise profile and surface texture of the rollers determine the final shape and surface finish of the rolled product.
Tungsten carbide (WC) is twice as strong as steel and has a hardness similar to corundum. Tungsten carbide rollers combine exceptional hardness with wear resistance and are available in custom sizes.
Carbide rollers ,also known as tungsten carbide rolls, tungsten carbide rolling rings, are widely used in steel forming, especially in cold rolling mills.
Carbide rings are worked as groups of 3 pieces, we also call it 3D carbide rolls.
Rolls can be separated according to their working positions: RO,RT,FO,PR or CA type.
Cemented carbide roller used on the stretch reducing mill for bars, thread steel bars and common wire with the durability 10 to 20 times higher compared to common steel roller. The surface quality and the steel bar size accuracy are greatly improved. The cemented carbide roller reduces effectively the production cost and improves the quality.
The main performance indicators of the roll are the strength of the core and the toughness and wear resistance of the working layer. The performance requirements for the finishing rolls of bar mills are mainly wear resistance and toughness, taking into account hot crack resistance and strength. Traditional bar mill rolls are usually made of integral centrifugally cast ductile iron rolls with a roll surface hardness of 74~78HSD. In order to further improve the wear resistance of the finishing rolls and increase the rolling capacity of the single groove, drawing on the experience of using cemented carbide roll rings in high-line finishing mills, in recent years, more and more manufacturers have adopted carbide roll rings instead of ductile iron rolls in bar rolling mills. more.
For key equipment such as rolls, the technical requirements are very high. It requires the selection of appropriate materials, hardness, contours, etc., and detailed and scientific design and manufacturing based on actual production conditions to ensure that the equipment can operate stably and efficiently and ensure product quality. and business benefits.
