Technical specifications of corrugated roll
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.
