Mechanical Processes for Descaling of Steel


Author: Crystal Wilson

Descaling is a metal cleaning process that removes unwanted surface deposits (scales) on metals to provide a smooth surface finish and is a part of the pre-finishing processes. Scales can be removed by mechanical descaling or chemical descaling. In the past, chemical descaling was considered to be more effective than mechanical descaling. However, new shot blasting technology has closed the gap in effectiveness between the two types of descaling processes. Many forging companies now prefer shot blasting because it does not use the harsh solutions often used in chemical descaling.

Recently, the leading North American producer of structural steel reached out to Sauer Compressors USA in need of a high-pressure compressor for their descaling process. For this operation, the company needed a compressor with a storage pressure of 4,000 psi and a flow rate of 50+ scfm, and they needed it quickly. Due to the immediate need, the call was forwarded to our rental department. The team immediately sprung into action and provided a Hurricane Series, WP4351, out the door the same day.

Sauer Compressors are used in a variety of applications around the world. Whether you’re looking to buy or rent, Sauer can help with applications up to 7,000 psi. Call us today!
