Quenching and tempering of welded carbon steel tubulars

Jul 29, 2001· Rolling Method. Steel that is rolled on a continuous mill usually has less scale than steel rolled on a reversing mill. Heavy mill scale acts as a blanket of insulation, which retards the heat transfer during quenching. If gauge control is not very effective, the tubular may exhibit wall thickness variation (see Figure 3). This will translate ...

Quenching - Wikipedia

In materials science, quenching is the rapid cooling of a workpiece in water, oil or air to obtain certain material properties.A type of heat treating, quenching prevents undesired low-temperature processes, such as phase transformations, from occurring. It does this by reducing the window of time during which these undesired reactions are both thermodynamically favorable, and kinetically ...

TECHNOLOGY OF HEAT TREATMENT OF MILL ROLLS
