High Pressure Water Descaling Machine for Forging Lines

A high pressure water descaling machine is used to remove oxide scale from hot billets before forging. It is commonly installed in forging lines where billet surface quality is important and where manual scale removal is not practical for continuous production.

During heating, steel billets form oxide scale on the surface. If the scale remains on the billet during forging, it can be pressed into the part surface. This can create pits, roughness and visible marks. A descaling machine helps remove this scale before the billet enters the forging process.

How Water Descaling Supports Forging

The machine uses controlled pressure and a focused cleaning section to remove surface scale from the hot billet. Depending on the model and line layout, the machine may be used for round bars, cut blanks or hot forged preforms.

The goal is to clean the billet surface quickly and consistently before it reaches the die.

Why It Is Used Before Forging

In hot die forging and closed die forging, surface cleanliness can affect the final product. Oxide scale trapped between the billet and die may create surface marks and increase the need for machining or finishing.

A forging descaling machine helps improve billet preparation and can support better product quality.

Suitable Line Layout

A typical production sequence may include billet cutting, heating, descaling, forging, trimming and cooling. The billet descaling machine is normally placed after heating and before forging.

This position is important because the billet should be cleaned immediately before forming.

Model Selection

When choosing a high pressure water descaling machine, consider billet diameter, billet length, scale condition, material type, heating method and production capacity.

For larger billets or heavier oxide scale, a larger or double-pump configuration may be more suitable.
