intermediate annealing
Simulated Annealing
Simulated annealing is a probabilistic search optimization process based on the physical process of annealing. Initially developed as a means of optimizing possible solutions to combinatorial optimization problems, Simulated Annealing has seen broad usage in numerous applicati......
Rolling principle of threaded parts
Rolling of Threaded Parts
Rolling is a metal forming process by which a thicker workpiece is reduced in thickness, usually by passing it through a pair of heavier rolls. With the development of sophisticated machinery, rolling has become one of the most commonly used processes for both mass produ......
Mechanism of contact fatigue spalling
Fatigue of metals is one of the most important failure mechanisms in engineering. Tensile tests have been used to study the fatigue behavior of metals. The reduction in load-recycling load ratio, or the fractional toughness, can be used as a measure of fatigue strength. The fractional toughness is......
Types of controlled rolling
Hot Rolling
Hot rolling is a process used in the manufacture of steel and other metal products. In hot rolling, the material is heated to a temperature above the recrystallization temperature, which is then worked or rolled into the desired shape and then cooled. Hot rolling is a process that is ......
Stabilization
Stabilizing the Global Economy
The global economy has experienced considerable instability in recent years due to numerous economic, cultural and political factors and shocks. These shocks, including the downturns in growth in the US, the Eurozone, UK and Japan, the escalating economic crisis in ......
Ingotless rolling
In today’s world, cold forming is a crucial process that is used in many industries. Cold forming allows manufacturers to produce components without the need for heat. All components can be formed to specific shapes and sizes without any heat being used. Cold forming is a process that is incredib......
Design Process Parameters of Step Shaft Die for Cross Wedge Rolling
Introduction
This report explores the design and craft parameters for wedge-rolling ladders, axes and dies. The scope of the report is limited to broader concepts relating to the mechanics behind the wedge-rolling process performed with ladders, axes and dies. It does not address the finer detail......
The principle of cross-rolled parts
Introduction
Cold rolling is a metal working process that is used to reduce the thickness of a metal sheet through passing the metal through rollers at a temperature below the metals recrystallization temperature. Cold rolling is frequently used to create sheet and other metal objects with a wide......
