We offer roll resharpening of the cast iron style mill roll. Most of these rolls are also called "chilled iron" or "white chilled iron" rolls. If you are performing the roll changes with your own maintenance crew, same day appointments can be made so your rolls will be resharpened in 1 day or less.

Synergy 500 – High Chrome Steel Roughing Mill Work Roll; Synergy 700 – Modified HSS Roughing Mill Work Roll; UNITED Rolls continues to further develop their enhanced carbide iron work rolls. The UR2EC enhanced iron work roll is designed to improve mill efficiency through extended campaigns due to excellent wear resistance properties.
The authors examined the laser surface alloying with different powders on different rolls, such as CBWCr powders on high NiCr infinite chilled castiron rolls [81], CBWCr and NiCrCr 3 C 2 powders on NCIR [38], NiCrCr 3 C 2 powders on semisteel rolls [39], and NiCrCr 3 C 2 powders on cast steel rolls [40].A comparison about the alloyed layer quality (cracks and pores) and the wear ...

At elevated temperatures Shorttime elevated temperature tensile properties See Fig. 1 Corrosion Resistant Type CA15 (UNS J91150) Description Type CA15 is an ironchromium alloy containing the minimum amount of chromium necessary to make the metal virtually rustproof, and is similar to the original "stainless steel" used for cutlery.
• An alloy (mixture) of iron and carbon (<%) • Plain Carbon Steel contains Manganese (>%) • Alloy steels contain additional alloying elements, typically C, Mn, Si, Cr, Ni, Mo, Al and sometimes Ti, V, Nb, W, Co. • Typically Steels have 95% or more Iron with relatively small alloy additions.
Spun Cast High Chrome Iron Rolls: These rolls are suitable for use at early finishing stands of Hot Strip Mills. It gives very high resistance to abrasion and wear coupled with high .
Steel Standards. ASTM's steel standards are instrumental in classifying, evaluating, and specifying the material, chemical, mechanical, and metallurgical properties of the different types of steels, which are primarily used in the production of mechanical components, industrial parts, and construction elements, as well as other accessories ...
The highCr cast iron rolls are mase by centrifugal casting process,the working layer contains 12~22% Chromium,through rational chemical composition alloions and different heat treatments,the matrix can be controlled as sorbite,troosite,bainite or martensite and certain kinds of carbides,such as Cr7,C3 eutectic carbites,Cr23C6 second carbites,Mo2C carbites to different purpose ...
The roughing section may comprise four or five fourhigh nonreversing stands or a single fourhigh reversing mill, dependent on the mill design. The finishing train may have up to seven fourhigh rolling stands in tandem, (see Figure 4). After rolling, the strip is cooled to a controlled temperature on a run out table using banks of water sprays.

· With over 3,500 grades of steel available, engineers depend upon accurate material testing to determine the materials needed for each specific project. Chemical composition of steel materials tells a lot about the material's tendencies, but testing ultimately proves the strength, hardness and quality of the final material.
