Free Settling Velocity Difference Layer Theory
The Free-Settling Differential Layer Theory
The Free-Settling Differential Layer Theory (FSDLT) is a theory that seeks to explain the production of bedforms on the seafloor. It suggests that sediment is displaced from the base of a bedform due to the sediment drifting away as it is transported al......
Bloom and billet (YB/T004-1991)
Overview
Rolling of steel products is of paramount importance in the production of modern steel. The billets or ingots of steel are heated to an elevated temperature and passed through a series of metal-walled rolls in order to shape them into the desired size. This process is known as rolling. I......
