PU Rollers for Steel Industry
First of all, PU rollers find extensive use in almost all finishing production lines of strip coils in the steel industry. Polyurethane products possess high resilience, excellent abrasion resistance, a low coefficient of friction, and good chemical resistance. These properties give them a longer service life compared to many other materials. As a result, they reduce the frequency of roller replacement and can meet the high load demands of continuous production line operation.
Secondly, in the steel industry, several main finishing lines utilize PU rolls. These include cold rolling lines, galvanizing lines, color coating lines, and leveling and shearing lines.
Specifically, in cold rolling, leveling and other finishing processes, polyurethane rollers ensure the flatness of the steel plate. During the rolling process, they control the precision of the steel plate’s rolling thickness. Moreover, in galvanizing and color coating production lines, they make the steel plate’s coating uniform and smooth, reduce scratches, and enhance the steel plate’s aesthetics. Additionally, they play roles in auxiliary transportation and accurate positioning.
Finally, PU rollers come in different types. High hardness tension rollers, steering rollers, guiding rollers, and pinch rollers are known for their high strength and wear resistance. Moderate hardness squeezing rollers and measuring rollers feature acid and alkali resistance, hydrolysis resistance, wear resistance, and high processing accuracy. Low hardness coated rollers, with a hardness range of 45 – 60 shore A, offer good machinability and resistance to organic solvents.
Urethane Products Application
Urethane products have various important applications. For instance, polyurethane coil saddles pads (steel coil pad) play a crucial role in the storage and transportation of steel coils. Placing these pads beneath the coils offers support and safeguards the coils from damage during storage and handling processes.
In addition, high hardness polyurethane tension rollers, steering rollers, and guiding rollers are quite notable. Thanks to their high strength and wear - resistant properties, they can meet the high load demands of the continuous operation of metallurgical sheet production lines.
Polyurethane Rollers in the Steel Industry
PU drying rollers exhibit remarkable resistance to acids, alkalis, and hydrolysis. This property effectively prevents cleaning liquids from the acid and alkali cleaning area from entering the subsequent process. Maintaining the integrity of the production process, it ensures no contaminants from the cleaning stage carry over, safeguarding the quality of steel products.
Polyurethane coated rollers have a hardness range of 45 - 60 Shore A. This hardness of urethane rollers maintains good elasticity and abrasion resistance, extends the life of the rolls, reduces the frequency of roll replacement, and lowers costs. These PU coated rollers are widely used in steel production, including anti-corrosion coating and marking of cold and hot rolled steel sheets, as well as in the production of galvanized and color-coated steel sheets, thereby improving the quality and durability of these products.
Advantage of using PU Rollersin the Steel Industry
PU rollers in the steel industry offer elasticity as a key advantage. During steel production equipment operation, vibrations and impacts are common. Their elasticity enables effective absorption of these forces, reducing potential damage to other equipment parts. This extends the equipment's lifespan and cuts maintenance costs. For instance, in large - scale rolling mills with high - speed operations, they protect delicate components from early wear.
As high - value - added steel products gain more importance, the use of PU rollers in steel manufacturing is expanding. They're not just for traditional uses. Polyurethane is now in related transmission accessories like unwinders and winders. These accessories protect steel coils during handling and ensure stable transmission, facilitating smooth production.
