A condition in which a fish has lost a certain percentage of scales.
A process in which oxide (scale), formed on steel when it is at high temperature in an oxidising environment, is removed from the steel surface. Primary scale is usually removed in the first stage of a hot working operation using high pressure water jets whereas secondary scale is usually removed by hot acid pickling or by shot blasting.
Operation to remove the superficial oxide layer of the billet while hot, with a high pressure jet of air or water.
Subjecting oxide annealed austenitic and high allot steel to an oxidizing or reducing salt bath to produce more readily a scale-free surface when pickled in a subsequent step.
Removing the thick layer of oxides formed on some metals at elevated temperatures.
The removal of mill scale or rust from steel by mechanical means, sometimes assisted by flame cleaning.
A process that removes the oxide scale from the surface of the stainless steel that developes from hot operations.
It is necessary to remove the scale from hot rolled bars or coil before bright drawing. This is normally carried out by shot blasting or pickling in acid. Other methods of descaling steel products include sand blasting, flame descaling and tumbling.
The process of removing scale from the surface of steel. Scale forms most readily when the steel is hot by union of the oxygen in the air with the iron in the hot steel.
The process of removing the scale from hot rolled bars before cold finishing. It is normally carried out by shot blasting or pickling in acid.
A process that involves removing the oxide layer, which forms on metal after hot forming processes.
