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
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
What are the advantages of hot rolling?
Hot rolled steel is steel that is rolled out when it is hot. We often see clips of sheets, slabs or bars of red-hot steel being rolled to give them a required shape. As steel becomes hotter, it can behave in a more plastic way and can be more easily sized and shaped by the rollers. We see flat sheets or long bars and rods of steel come out of the rollers. Railroad track is hot rolled to make it into the shape we know. We know that steel that is hot rolled will be more flexible than cold rolled steel because the hot-rolled steel has larger crystal structure. Cold rolling creates smaller crystals in the matrix, and that makes cold-rolled steel stronger and harder, but less flexible. If the cold rolling process is not carefully monitored, the steel can become brittle and can be hard to work with.
What is hot working of steel?
The hot working of steel can easily be defined as " the mechanical working on steel after heating above the recrystallization temperature" e.g. forging, hot pressing, drawing etc.
