High Thermal Efficiency Heating Calender Roll For Non Woven Line

High Thermal Efficiency Heating Calender Roll For Non-woven Line

Non-woven Heating Calender Roll material:

All high-quality alloy steel (38CrMOa i, 42CrMo, 60CrMo, 9Cr2Mo) is used as the base material, and is formed by mechanical processing and heat treatment. Surface hardness HRC58~62.

Non-woven Heating Calender Roll Heating method:

Hollow inner liner spiral heating:

Drill deep holes in the forging, install spiral liner or spray liner in the middle space, so that the heat transfer oil flows (or sprays) in a directional manner in the spiral liner to achieve the purpose of heating. Temperature difference ≤1.5°C.

Peripheral drilling heating:

Drill deep holes evenly around the roller body to make the heat transfer oil circulate and flow in the peripheral holes for heating, with a smaller temperature difference (<1°C) and higher thermal efficiency.

Non-woven Heating Calender Roll Pattern:

It can be engraved into any regular and irregular patterns such as square dots, round dots, elliptical dots, diamond shapes, cross shapes, stripes, etc. according to user needs.

● After quenching and engraving, the hardness layer is > 5mm, while the hardness layer of the original hot rolling roller using nitriding process is only 0.4~0.5mm;

● The size and depth of the rolling point remain basically unchanged after long-term use.

● Greater advantages: correct pattern, optional pattern, depth and angle;

Synchronized with the quality of European hot rolling rollers.
