The excellent economy performance of Super anti-friction carbonized tungsten coating corrugated roll 1. The hardness is only second to diamond excellent anti-friction performance. l The life is 3-5 times than chrome plated corrugated roll. l Decrease the change time and cost by 65-80%(include the stop and change expenses ) l Increase the times to repair l Reduce the expense in corrugating cardboard per square l Avoid current depreciation of related parts caused by concave abrasion(such as glue roll, doctor roll and pressure roll and so on) 2. The stable quality of corrugating cardboard Because of the excellent anti-friction, the corrugation height abrasion is between 0.06-0.08mm once a time in use. Meanwhile, the corrugation pattern wont distort after optimization, and the amount of glue wont increase with the abrasion of corrugation top. So it avoids kinds of limitation of common cardboard, and insures uniform quality of corrugating cardboard. 3. Reduce the material consumption cost of corrugating cardboard l After optimization, the super anti-friction carbonized tungsten coating corrugated roll can get the corrugation pattern of less paper consumption rate. l The less abrasion of corrugation height can decrease more than 1% paper consumption rate than chrome plated corrugated roll. l The less abrasion of corrugation top can make the paste consumption amount less and more stable, and reduce the paste consumption cost by 20-50% l Avoid the quality limitation of kinds of common cardboard, and decrease the wastage loss by 30-50%. The technical specifications of Super anti-friction carbonized tungsten coating corrugated roll 1. Special 48CrMo alloy steel fine forgings for corrugated roll 2. The hardness of base unit in medium-frequency quenching>HRC55 3. The thickness of anti-friction carbonized tungsten coating is between 0.06 and 0.08 4.
