meaning of Hi in cold rolling mil
When Turbine shaft temp is below 100 deg.centigrade,Then rolling of turbine carried out it is called cold rolling.
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...
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

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

Brass is the combination of the metals copper and zinc. Its manufacturing process involves melting, hot rolling, annealing and cold rolling, and finish rolling.
When turbine shaft temp is below 100 deg.centi, then rolling of turbine carried out it is called coldrolling wider.

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)
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.
