These usually have a scale breaker as the first stand where the mill deforms the slab sufficiently just to loosen the scale, which is then removed by the highpressure water jets. Roughing scale breakers are usually vertical edgers, capable of reducing the width of the slab by up to 5–10 cm and causing stresses at the steel surfacescale layer interface which then separate the scales.
Steel pickling and oiling is a metal surface treatment finishing process used to remove surface impurities such as rust and carbon scale from hot rolled carbon steel. The steel is submersed in a bath of pickle liquor, a solution of Hydrogen Chloride acid, to remove the impurities from the surface of the steel.

· Milling is an important process of manufacturing technology and basically it refers to the removal of metal from the work piece using a tool which has several cutting points and is rotating about its axis. Thus each cutting point removes a little bit of the metal but since there are multiple such points and the tool is rotating at a fast speed, the overall removal is quite brisk.
Discover how laser rust removal is an effective process for cleaning up metal parts. Metals such as aluminum, steel, copper, magnesium, lead or stainless steel can be cleaned with Laserax laser cleaner. Rust, varnish, oil, paint and other contaminants will not resist to our industrial laser cleaning systems.
Sand blasting or even media blasting puts you into a whole different ballgame. I would certainly farm this process out. Stuart., 04:40 PM. adama. Looking at it anouther way blasting vibratory approaches will easly remove the scale but will do little to improve the aperance of the piece smooth iregularities in the sphere. Persoanly i like a small angle grinder and a good flap ...
scale removal operation. Sprays above and below the transfer bar blast it with 1,500 psi jets of water to break up the scale that has reformed since the descaling operation at the entry of the last roughing mill, as well as any scale that has persisted through earlier descaling operations. After descaling by the lowpressure headers,
•Requires removal of all mill scale, rust and paint from the surface •Staining from rust, paint and mill scale is permitted to remain, but must be evenly dispersed •Staining cannot exceed 5% of each 9 in2 of prepared surface •Viewed without magnifiion
Companies producing sheet metal usually utilize milling because it is cost effective, and the mill scale is an unwanted byproduct of the process. Mechanical Processes for Descaling of Steel – IspatGuru. Sep 08, 2017· Removal of scale is virtually impossible by hand. It is extremely tedious and time consuming using power tool cleaning methods.

As a material removal process, machining is inherently not the most economical choice for a primary manufacturing process. Material, which has been paid for, is cut away and discarded to achieve the final part. Also, despite the low setup and tooling costs, long machining times may be required and therefore be cost prohibitive for large quantities. As a result, machining is most often used for ...
