  Forged steel work roll performs as a tool to transform materials under normal room temperature,  therefore , it is  the most wear and tear spare parts during the rolling process . With 2%Cr, 3%Cr, 5%Cr material series , we have greatly improved our products both in terms of quality and diversification . Currently , our product is widely used in a variety of applications , such as anti hydrogen-attack roll, ultra-deep hardened roll, anti-roll mark roll, anti-roll accident roll and the high wear resistance roll and so on.

Cold rolling mill intermediate Roll  applies to high precision 6-Hi (as well as a few 8-Hi) mill, named from working location between work roll and back-up roll, mainly used to control the shape of strip. Material specification of 2%Cr, 3%Cr, 5%Cr, Semi-High Speed Steel are available.  

Forged steel back-up roll is mainly used in 4-Hi mill and 6-Hi mill. The diameter of roll barrel is 350~1400mm. The material of back-up roll includes 60CrMo, 9Cr2Mo, 86CrMoV7, 70Cr3Mo etc. The main types of mills: back-up roll of 650mm Mill, 900mm Mill, 1050mm Mill, 1250mm Mill, 1450mm Mill. BIEC BACKUP ROLLS ARE USED IN 4 HI and 6 HI REVERSING AND TANDEM MILLS FOR ALL PRODUCT ROLLING SUCH AS STEEL , STAINLESS , ALUMINUM, BRASS , COPPER UPTO SINGLE PC WEIGHING 32000 KGS  

Sendzimir mill is favored by high technology customers because of high rolling precision , such as very thin strip and difficult deformation silicon steel, stainless steel.  The material of Sendzimir work roll is tool steel, die steel and high-speed steel. These are materials of high hardness . The rolls are manufactured under quenching and tempering processes of high temperature . During the tempering process, secondary hardening is used to reach hardness of 60-63HRC, 61-64 HRC, 63-66HRC etc, for different work rolls .  High hardness tool steel and die steel are used as raw materials for Sendzimir intermediate roll. The rolls are also manufactured under quenching and tempering process of high temperature. During tempering process, secondary hardening is used to reach hardness of 55-60HRC for different intermediate rolls.

  Available in diameters of 6" to 36" and up, we also design and manufacture custom wheels for your specific design application in any configuration. And our sales engineers are always ready to make recommendations when these wheels need to be integrated into complete wheel assemblies on time and when you need it. Our large inventory of carbon and alloy steel materials, coupled with our in-house rough and finish machining capabilities (up to 40" in diameter), makes rush delivery and breakdown situations our specialty. British India Engineering Corporation is dedicated to keeping your business moving and getting you back on-line because lost time is lost money. If you don’t have a written specification or drawing, Irwin has the ability to reverse engineer your part and produce it to original specifications to get you back on-line quickly and cost effectively. Reconditioned Crane & Heavy Wheel Assemblies In addition to our new crane and custom heavy-duty industrial wheels and wheel assemblies, British India Engineering Corporation is also able to repair and recondition your existing wheel & axle sets.  Whether your assemblies require new axles, bearings, bearing housings or a complete overhaul, British India Engineering Corporation can get you back into production ASAP, often at a cost far less than buying new wheel assemblies, and they will be shipped back to you fully assembled, painted, lubricated and ready to install.
