HSS Manufacturing Methods The transformation of steel strip into hollow structural sections (HSS) is the result of a series of operations including formi ng, welding and sizing. Currently three methods are being used in North America for the manufacture of HSS. These methods are described below.

Bottom to Top: CR700/1000-DP, CR950/1200-MS, CR1150/1400-MS. S-5. Citation A-33 provides guidelines for roll forming High-Strength Steels: Select the appropriate number of roll stands for the material being formed. Remember the higher the steel strength, the greater the number of stands required on the roll former.

There are two production lines of rolls in the company : One is the production line of centrifugal cast work rolls for hot strip mills and wide & heavy plate mills. The other is the production line of forged rolls. It can also supply the forging steel ingots, forged blanks, casting and forging pieces for domestic and overseas customers.

1) Front stands work rolls Two types of HSS rolls are available; CPC (Continuous Pouring Process for Cladding) rolls and CF (Centrifugally Cast) rolls. CPC rolls are by far the best HSS material as they include the largest amount of alloying elements by the special cladding process which results in the least wear and the least oxidation.

Theses HSS rolls of the first type contain large amount of primary VC carbides embedded in a tempered martensitic matrix. These VC carbides have a high hardness (3000 HV) so they induce good wear resistance. Unfortunately, the surrounding matrix hardness is between 500 and 1000HV, and its wear resistance is weak

Japan Advanced Roll utilizes the advanced ESR system on rolls made from high-tensile steel and hard tinplate, supplying semi-HSS rolls with a uniform (non-composite) structure that combines high levels of both wear performance and ease-of-grinding.

HSS Mill Rolls HSS rolls have high hardness and good wear resistance at high temperature. These rolls are manufactured by Centrifugal Casting(CC) method and the roll core is filled with spheroidal graphite cast iron.The adequate chemical composition control and proper heat treatment ensures the hardness of roll working layer to reach as high as 80-85HSC.

Advantages of 's HSS Rolls (1) Higher work efficiency When wear resistance can be markedly improved, users can also benefit from a dramatically improved roll consumption rate. It can also significantly extend intervals between roll replacements. (2) Higher product yield

HSS Rolls are successfully replacing other conventional rolls which were till date being used in bar mills, structural mills and strip mills. Since the HSS Rolls have a longer product life the mills using these rolls vouch for lower roll costs per tonne, less mill down time in turn an increase in overall production.

Steel Industry. In our high-tech foundry we produce work rolls for the steel industry with finished weights up to 85 tons. Starting from a diameter of approx. 300 mm, we cast high-grade cast iron and cast steel rolls for all applications in Plate Mill, Hot Strip and Section Rolling Mills. All rolls manufactured by us imply the following properties:

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 ...

HSS Rolls, produced by horizontal centrifugal casting process, are all compound rolls with high speed steel as the work layer and nodular iron as the core. The material of HSS contains plenty of alloyed elements such as Mo, V, W, Cr etc. The high hardened eutectic carbides & second carbides, such as MC, M2C, M6C evenly distributed in tempered ...

Wear resistance of HSS rolls have been found 3 to 4 times superior than that of Hi-Cr rolls . Application of HSS or semi-HSS work rolls in roughing mills is also found beneficial over chromium steel rolls . However, there are some limitations in using HSS rolls. Such rolls increase friction at roll bite and they are more susceptible to failure ...

The fine microstructure and high hardenability of this material mean that there is no fall-off in hardness to discard so ensuring consistently excellent performance throughout the life of the roll.
