The following is the main precision index of corrugated roller:

New corrugated roll corrugated type: corrugated height, corrugated number of 300mm, corrugated top and bottom arc radius, paper consumption rate and micro corrugated Angle and other parameters are economical and reasonable.

Quenching layer: layer depth of 5 ~ 7mm, hardness is greater than HRC5, uniform hardness, no soft belt grooved roll.

Surface coating: microhardness HV900 ~ 1050, the number of microcracks per LCM up to more than 400.

High speed corrugated roller: twice fine grinding:

Run-out tolerance of roof circle 0.025 roof height deviation +0.The lateral deviation of the flute from the axis is 0.025.

The deflection of the Angle is plus or minus 1 degree.

The middle height deviation of the middle high roller is 4-10% of the middle high value. The indexes of the middle and low speed corrugated roller conform to gb1207-89.
