What is a rolling mill?
In metalworking, rolling is a metal forming process in which metal stock is passed through a pair of rolls. Rolling is classified according to the temperature of the metal rolled. If the temperature of the metal is above its recrystallization temperature, then the process is termed as hot rolling. If the temperature of the metal is below its recrystallization temperature, the process is termed as cold rolling. In terms of usage, hot rolling processes more tonnage than any other manufacturing process and cold rolling processes the most tonnage out of all cold working processes
How strength of a material can increased?
Other elements can be added in certain quantities to make alloys of that metal. Properties such as ductility and hardness can be tailored by adjusting cooling times, heat treating or cold working. Forging can sometimes help to rid the metal of unwanted purities and to improve the grain structure.
What is the difference between hot and cold working table?
The names say it all...Cold working is done cold, i.e. part at room temperature. It essentially pushed into something to deform it. This yields the part, technically increasing its yield for further use, but it will decrease the stress required to go from its new yield to its max tensile. Be advised, for very thick parts, like bars above 2", only the outer portions will cold work, the core will keep the same properties as un-worked metal.Hot working heats the part up above its recrystallization temperature so along with deformation, the part recrystallizes, thereby not cold working it. Hot working does not give a yield strength increase like cold working does.
What is the mass of metal cast into a mold and ready for recasting?
A mass of metal cast into a mould is called either an ingot mould or a cold mould. the one that is ready for recasting is usually the ingot mould. A cold mould is one that has been cast on design that maintains its mould.
How would temperature affect bridges?
the metal or concrete might expand if it gets too hot and compress when it gets too cold.
What is cold forming?
Cold forming refers to the strengthening of metal through plastic deformation. It is also known as strain hardening or cold working.
What is denser hot metal or cold metal?
Cold metal.

Can biaxsig be used for treatment of cold sores?
Biaxin is an antibacterial agent, and cold sores are viral, so it is not effective for treating cold sores.
