Advantages and Features

Efficient descaling

The wet scale breaking work roll uses high-pressure water or coolant as the medium, combined with the special design of the roll surface, which can quickly and thoroughly remove the oxide scale on the metal surface, significantly improving production efficiency.

environmental protection and energy conservation

Compared to traditional dry scale breaking processes, wet scale breaking work rolls use water or coolant as the medium, reducing dust pollution and energy consumption, which is in line with the development trend of green manufacturing.

Protecting the metal substrate

The wet scale breaking process can effectively reduce damage to the metal substrate, avoid excessive wear or scratches, ensure the quality of the metal surface, and extend the service life of the product.

Adaptable

Wet scale breaking work rolls are suitable for various metal materials, such as stainless steel, carbon steel, aluminum alloy, etc., and can handle metal sheets or coils of different thicknesses and shapes.

High degree of automation

Modern wet scale breaking work rolls are usually equipped with automated control systems, which can achieve precise control of scale breaking pressure, water volume, and speed, reduce manual intervention, and improve production stability.

Instructions for Use

Equipment installation

The wet scale breaking work roller should be installed on a flat and stable foundation to ensure the stability of the equipment during operation. During installation, attention should be paid to connecting the high-pressure water pump and coolant supply system to ensure sufficient medium supply.

Parameter Settings

Reasonably set the scale breaking pressure, water volume, and roller speed based on the type, thickness, and degree of oxidation of the metal material. It is recommended to conduct a trial run before starting the device and adjust it to the optimal parameters.

routine maintenance

Regularly check the wear of the roller surface and replace severely worn roller surfaces in a timely manner. At the same time, clean the high-pressure water pump and coolant pipeline to prevent blockage or leakage.

safe operation

Operators need to wear protective equipment to avoid injury caused by high-pressure water or coolant splashing. When the equipment is running, it is forbidden to put hands or other objects into the work area.

Fault handling

If any abnormal operation of the equipment is found (such as poor scale breaking effect, excessive noise, etc.), it should be stopped immediately for inspection, and the fault should be eliminated before continuing to use.

Common problems and solutions

Poor scale breaking effect

Reason: Insufficient high-pressure water pressure or severe wear on the roller surface.

Solution: Check the high-pressure water pump and pipelines to ensure that the pressure is normal; Replace the worn roller surface.

Excessive equipment noise

Reason: Unstable installation of the roller surface or damaged bearings.

Solution: Adjust the installation position of the roller surface again; Replace damaged bearings.

Coolant leakage

Reason: The pipeline connection is not tight or the sealing components are aging.

Solution: Re tighten the pipeline connection; Replace aging seals.

Scratches on metal surfaces

Reason: The roller surface is rough or there are hard impurities on the metal material surface.

Solution: Polish or replace the roller surface; Clean the surface of metal materials before scaling.

The device is running unstably

Reason: Control system malfunction or unstable power supply.

Solution: Check the control system and power supply, and troubleshoot.
