Rolls

Material characteristics

High-performance high-speed steel roll ring material: The high-performance high-speed steel roll ring is a steel-based roll ring that implements the national cast steel roll standard GB / T1503-2008. Its main alloy components are vanadium, nickel, tungsten, molybdenum, niobium, cobalt and other elements. , The carbon content is less than 1.6%, the phosphorus content must be controlled below 0.03%, the chromium content must be controlled below 5%, and the sulfur content must be controlled below 0.03%, so that the material's wear resistance and impact toughness are fully guaranteed At the same time, to ensure that the roller ring will not appear micro cracks, block loss, ring burst phenomenon in use. In particular, the tungsten content is strictly controlled, and segregation will not occur during centrifugal casting, so the hardness drop after each re-grinding is small, and the amount of steel passing will not decrease significantly.

All roll rings of our company are inspected 3 times one by one to ensure the inherent quality of the roll rings. All roll rings are tempered 3 times to obtain the best metallographic structure to ensure the best product performance.

Tungsten carbide rolls are rolls made by powder metallurgy using tungsten carbide and cobalt as materials. There are two types: integral and combined. It was born after the advent of powder metallurgy technology in 1909, with the development of the metal processing industry. It has been widely used in various fields of plastic metal processing, from non-ferrous metals to steel, from hot-rolled wire and pipe to cold-rolled foil. , Rebar, etc.
ingredient
The composition of tungsten carbide rolls is different due to the different working conditions of the rolls. Even in the same finishing rolling unit, the roll composition of different stands is also different. High-speed wire rolling mill rolls are mainly tungsten carbide rolls with cobalt as the binder. Due to poor water quality, a few continuous casting and rolling mills also use tungsten carbide rolls with Co-Ni-Cr as the binder, and the cost is also low.
organization
The metallurgical structure of tungsten carbide rolls is composed of matrix phase WC and bonding phase Co.
performance
The hardness of tungsten carbide rolls increases with increasing WC content, while the toughness increases with increasing content of binder phase.
Our company produces hard alloy flat wire rolls, crimping wheels, profiled rolls with high precision, high hardness, and wear resistance. The product size standards can be pressed. The product accuracy can reach 0.001mm. Pressing of aluminum, zinc, stainless steel and other wires, the products made are in a leading position in the industry
