What is cold rolling of steam turbine?
When Turbine shaft temp is below 100 deg.centigrade,Then rolling of turbine carried out it is called cold rolling.
Why does cold rolling decreases hardness?
Cold rolling involves application of load due to this the grains are elongated...so the material is work hardened and causes to rise internal stresses in the material...due to these stress cold rolling decreases hardness....so after cold rolling a heat treatment process is preferred...
Does hot rolling create greater drafts or does cold rolling?
Yes hot rolling create greater draft than cold rolling . This is because during hot rolling the material is hot due to which it is soft thereby making it easy for more draft
What is the standard thickess of cold rolling?
0.004"
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
What is the process involved in making brass?
Brass is the combination of the metals copper and zinc. Its manufacturing process involves melting, hot rolling, annealing and cold rolling, and finish rolling.
Into what classifications is rolling mill machinery divided?
The U.S. government divides rolling mill machinery into four classifications: hot rolling mill machinery (except tube rolling), cold rolling mill machinery, other roll milling machinery (including tube mill machinery)
Would wider tires increase or decrease friction?
Wider tires increase friction due to larger contact area with the road. This can provide better traction and handling, especially in wet or slippery conditions. However, wider tires can also increase rolling resistance, which may affect fuel efficiency.
What is cold roll?
Cold rolling is simply crushing the steel into thin plates (done using large rollers) when the steel is at a low temperature. Cold rolled, grain oriented (CRGO) silicon steel is often used in transformer cores. When Steel is heated (annealing), the silicon - iron crystals become aligned. Cold rolling crushes the crystals into random positions. This helps minimize stray losses in transformers, making them more efficient. A non-electrical application of cold rolling is in the making of samurai swords.
Which steel is expensive hot rolled or cold rolled?
It takes much more energy to roll a sheet of metal in cold rolling than it does for hot rolling. Heating up a sheet of metal makes the material more malleable, so when it is rolled between two rollers, it can form into a flat sheet much easier. A cold sheet of metal that is not heated up will be put through the rollers and have a higher amount of energy needed to push it through. Though there is less heating required, this is balanced out by the fact that it must be pushed through with more energy.The cold rolling process is an expensive one, especially compared to the process of hot rolling sheet metal. For example, since cold rolling requires that workers frequently clean parts like the rollers, cold rolling has extra costs for any supplies needed to clean the parts, downtime while the parts are being cleaned and labor costs for the worker who does the cleaning. Also, the additional energy needed in the cold rolling process adds cost to the final product. call me if u need more: 0784971498
What is is 2062 is it hot rolled or cold rolled?
2062 is a type of structural steel alloy primarily used in construction and manufacturing. It is typically available in hot rolled form, which involves rolling the steel at high temperatures to shape it. Hot rolling enhances its toughness and ductility, making it suitable for various applications. Cold rolling, on the other hand, is not commonly associated with 2062.
