High Speed Steel (HSS) Rolls
Steel rolling technology has progressed in recent years, improving product quality, enhancing productivity, and reducing production costs. 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. The HSS rolls are now manufactured by the CPC process, centrifugal casting (CF) process, or hot isolating pressing (HIP) process to meet specific requirements.
Technical Specification
Hardness: The alloy content is higher than that of conventional roll material, with two or more types of carbides being dispersed. The HSS rolls are harder than roll materials of equivalent carbon content as shown in fig. and are expected to provide higher resistance to wear and surface roughening.
Chemical Properties
With the addition of certain chemicals like of Vanadium, chromium, tungsten, molybdenum, niobium etc. HSS rolls outer shell gets good thermal stability, high hardness under high temperature and excellent wear and tear resistance against hot material.
Quality Control
Our quality control department is equipped with the latest testing equipment to analyze various physical and chemical properties to ensure the highest quality.
Advantages
Lower Roll Cost per Tone: It is estimated that the useful life of HSS rolls is almost 5-6 times more than that of conventional rolls. Meaning that over all cost of rolls consumed per tone of finished steel produced is much less.
Increase in Production: Because of the longer product life of the HSS Rolls, the time required for repetitive changing of roll pass is considerably reduced. This regular change of roll pass consumes a lot of time and results in production loss. In addition to production loss, this also accounts for huge energy loss.
Zero wastage of raw material: Since the grooves/ passes of the HSS rolls have a greater resistance to wear and tear, the shapes of the grooves are stably maintained. Because of the high swelling factor of the HSS rolls with time the barrel swells in turn reducing the size of the worn out grooves.
