What is a hot rolled thread?
It's a thread that's been formed by rolling the piece while hot between two dies.
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.
Difference between hot working process cold working process?
Hot mechanical working operation on the missing piece we do. Mechanical operation of the work we do on a normal cold temperatures.
What is hot working of metals?
Hot working of metals is defined as a process of forming metals by deformation at temperature above the recrystallization temperature.
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 process called when metals are rolled into thin sheets like aluminum foil?
The process of rolling metals into sheets is called (no surprise) rolling. The metal is passed through a rolling mill and is reduced in size in steps. The metal might be hot rolled or cold rolled, and the choice of process depends on the metal and on what the finished product needs to be like. In the case of aluminum foil, a block of aluminum is first hot rolled, and the metal is passed through the rolling mill a number of times until it is thin enough to be rolled and moved to a cold rolling mill. In the cold rolling mill, it goes through a number of roller sets until the desired thickness is achieved.
What is mean by hot working and cold working?
When ur hot and ur working then it is hot working, if ur cold and ur working then it is cold working
What is mean of 'hi' in rolling mills?
In rolling mills, "hi" typically refers to the "hot intermediate" stage of the rolling process. This stage involves the initial heating of metal before it is shaped into desired forms through rolling. The term emphasizes that the material is still in a heated state to facilitate easier deformation and improve the final product's properties.
What is reason of web waviness in steel beams in hot rolling?
Web waviness in steel beams during hot rolling is primarily caused by uneven cooling and thermal gradients within the material. As the steel cools, differential contraction can lead to distortions, particularly in the web area, where the geometry is more susceptible to such stresses. Additionally, variations in rolling pressure and inconsistent material properties can exacerbate these deformations, resulting in waviness. Proper control of the rolling process and cooling rates can help minimize this phenomenon.
Who is better the Red Hot Chili peppers or the Rolling Stones?
definitely RED HOT CHILI PEPPERS!!!!
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
