Cold rolling and hot rolling work with two methods. Both involve squeezing, extending and thin chunks of metal between two or more rollers of steel. The difference between these two methods is the use of temperature and the final results of the rolling, including the strength, the flexibility to complete the steel!
One of the differences between hot and cold temperature rolling is the name. Hot rolling is at a higher temperature and cold rolling in the lower layer. Cold rolling is done at room temperature. The "hot" hot rolling is not simply a bit warm, but hot enough to affect the structure of the metal. This is about 1500 degrees Fahrenheit. This heat makes the metal rough, or “scale.†It also recrystallizes, which means that the molecules are rearranged because of the heat that, when the steel cools, this rearrangement makes the metal different before heating.
Compared to cold rolled bars, hot rolled bars are soft. The cold rolling process is metal, which makes it very difficult. Recrystallization during hot rolling makes the steel slightly softer. It is still steel, however, it is difficult to compare with other materials.
Flexibility is more flexible than cold rolled steel hot rods. This is because they are a bit soft. Cold rolled steel from the metal can withstand more work. Hot rolled steel may be more flexible, but it cannot put as much stress. The metal process can cause hot rolled steel to crack if it lasts too long. This allows hot rolled steel to provide less necessary attention for the project, cold rolling more detailed works.
The colors have different appearances of hot and cold rolled steel. Cold rolled metal is a gray color, the color of the metal itself in Chongqing Steel Mold Factory. Hot rolled steel slows down because of heat. Heat recrystallizes the steel and introduces more oxygen, resulting in a chemical reaction called oxidation. This blue oxidation.
Texture heat can also affect the texture of the steel. The oxidation of blue and the extended heat make the hot rolled steel rough and cold rolled. Because cold rolled steel does not go through these processes, it feels smooth and shiny.
Maintenance of rolled steels for rebars in Chongqing needs to be maintained, such as galvanizing and chemical painting than hot rolling. This is because treatment adheres to the metal itself. The hot rolled steel oxide layer prevents chemicals from reaching the metal. In order to chemically color, stimulate or treat steel, this oxidation must be removed.
