Aluminum Roller Track

The aluminum alloy manual roller has the advantages of high unit energy, light weight, small inertia, and suitable look of mild and rust. it's far broadly used in embossing printing, coating, winding, blown film, lamination, coating, slitting, paper making, and textile. awaiting the production line.


The construction of the aluminum alloy guide rolls may be more or less divided into:
(1) hole aluminum curler: the inner bearing kind shape, the bearing is set up at the bearing holes in the two faces.
(2) coupling aluminum roller: the roller frame is hooked up to the metal shaft or the chrome steel shaft quit at both ends, and is an integrated structure.
(3) water-passing aluminum roll: cooling or heating liquid enters and exits thru both facets and circulates inside the roll body.
(four) unique rolls: diverse unique creation rolls processed as proven.

How to improve the service life of the guide roller. Through the comprehensive evaluation of the plasma alloy guide rolls, it can be known that the application of the plasma cladding technology on the guide rolls of the rolling mill can significantly improve the service life of the rolling mill guide rolls, thereby reducing the cost of guide roller handling and loading, and reducing the labor intensity and guidance of frequent replacement. The waste of steel rolling work time caused by the disassembly and handling of the roller can increase the amount of steel rolling, save a large amount of high-quality steel, and also reduce the safety accident caused by the damage of the guide roller.

When the aluminum guide roll is glazed, the surface area of the rubber is greatly reduced, and the transfer performance to the ink and the fountain solution is deteriorated, resulting in difficulty in printing.

The following set of data can illustrate the severity of glazing:

Ordinary rubber roller: After the printing machine reaches 1 million revolutions, the rubber surface begins to glaze.

High-quality rubber roller: After the printing machine runs 5 million revolutions, the rubber surface area is less than 30%.

High-quality glazed rubber roller: After 30 million revolutions of printing machine, the rubber surface area can maintain more than 70% of the original.

The aluminum guide roller is glazed to make the surface of the aluminum guide roller hard, the elasticity is reduced, and the printing pressure is increased, which makes it difficult to adjust the pressure of the ink roller and the water roller.

It directly leads to insufficient density of printed ink, slow drying, unstable ink balance, increased paper waste and difficulty in cleaning aluminum guide rolls.
