tungsten carbide corrugated roller
The economic performance of tungsten carbide corrugated roller:
Corrugated roll 3-5 times using life; Reduce the use of corrugated paperboard and corrugated roller per square metre cost;
Avoided by concave in the corrugated roller wear caused by the frequent loss of the relevant member（Such as glue roller, rubber roller and pressure roller, etc）Stable quality of corrugated board
Due to the excellent performance of wear resistance, Corrugated with each cycle of stare blankly high wear in 0.06-0.08 mm, The optimized stare blankly little deformation，Glue quantity will not increase by stare blankly head wear, To avoid the various common cardboard quality defects，Ensure the ideal of corrugated board consistent quality， reduce the material cost of the corrugated cardboard，
And coated carbide can be optimized to obtain type of paper consumption rate lower;
Tiny stare blankly comparable high wear corrugated roll reduce more than 1% of the consumption of paper costs
To avoid the various common cardboard quality defects, reduce waste more than 30-50% of the loss
The technical index of the tungsten carbide corrugated roll,
1、Corrugated roller dedicated special 50 crmo alloy steel forgings;
2、Basic corrugated roller intermediate frequency quenching hardness > HRC58 depth limit deviation of 0.025 mm or less
