To overcome the drawbacks of the state-of-the-art technologies for texturing skin-pass rolls, a new approach was taken: High-speed laser melt injection (HSLMI) is a new method for generating MMC tool surfaces with high …

HOPE mini texturing box set. These texturing tools are made to be the best!!!! The wheels are hardened HSS and are specially designed with an parabolic curve BUT with flats left on the top of the wheels that enable the wheels to create different textures and patterns.

The material of Hss rolls should have the following characteristics: 1. High hardness: High-speed steel rolls need to have high hardness to ensure accurate control of …

Compared with ductile iron rolls and high-nickel-chromium rolls, the single-groove (time) steel passing is higher, which saves roll changing time, improves rolling mill operation rate, reduces roll consumption, reduces production costs, and …

High-speed tool steel (HSS) rolls were devoloped to meet the demand. Usage of HSS rolls to hot strip mill roughing stands, structural mill universal rolling stands, and bar and wire rod mill intermediate stands.

The steel mill uses laser cladding technology to repair its special-shaped rolls. The dimensional accuracy and surface quality of the repaired special-shaped rolls meet production …

The HSS roll material contains high alloy elements such as vanadium, tungsten, chromium, molybdenum, niobium, etc. The roll has good thermal stability, wear resistance, high expansion coefficient, good thermal conductivity, high roll neck strength, high steel throughput in a single groove (time), reducing consumption and improving the overall benefit of the plant.

EDT technique is a kind of texture method to melt the material on the barrel by spark-discharge between the electrode and the barrel in the …

4.2 Texturing A mechanical method like shotblasting cannot be used for texturing the HSS rolls, since it yields only low roughness value (Ra) with HSS grades. Electro Discharge Texturing …

This trend has increased the demand for rolling mill rolls of higher performance, longer life, and higher reliability. High-speed tool steel (HSS) rolls were devoloped to meet the demand. Usage of HSS rolls to hot strip mill roughing stands, structural mill universal rolling stands, and bar and wire rod mill intermediate stands.

hss rolls The microstructure consists of tempered bainitic / martensitic matrix with primary and secondary carbides. Primary carbides MC, M7C3, M6C and M2C are originated during the eutectic solidification. Secondary carbides are precipitated during the High Temperature quench and tempering. The rolls are cast with the right structure to ...

Two alloys grades for work rolls used in the roughing stand of Hot Strip Mill (HSM) are compared. The first grade known as High Chromium Steel (HCS) is presently the most widely used alloy for such an application, while the second one known as semi-High Speed Steel (semi-HSS) is the new grade developed to improve the overall performance of the work roll in the roughing …

Calculations indicated the possibility of replacing the working rolls made of high chromium cast iron Hi-Cr with those made of HSS in the F5 and F6 cages, which will contribute to an increase in ...

Laser and electron beam-based texturing technologies produce repeating patterns and micro-features in the roll surface that prevent the sheet being acceptable for use in exposed automotive applications. Roll processing times are dramatically slower than EDT. Furthermore, consumption of inert gas during the texturing process is wasteful and costly.

The twin-roll continuous casting method is one of the most frequently used casting methods in aluminum sheet production. In this method, the liquid metal, which has passed through certain filtration processes, solidifies as soon as it passes between two counter-rotating steel rollers [].In the following process, depending on the final plate thickness, cold rolling …

This helps to increase roll hardness, enhance wear resistance and reduce wear surface roughness. Selection of Traditional Hot Rolling Mill Roll Material and Heat Treatment Process. Hot rolling rolls often work in a high-temperature environment of 700°C to 800°C. They are in contact with hot steel billets and need to withstand strong rolling ...

The test results show that HSS rolls have the highest hardness and strength, the lowest carbide volume fraction, and the longest thermal fatigue life.

shop. If a major defect is present in a forged roll, e.g. due to a mill incident, catastrophic roll failure may occur in a violent, explosive manner. Improvement of the value-in-use of a work roll implies a superior wear resistance, a superior damage resistance, and elimina-tion of the safety risks associated with explosive roll failures.
