Cold rolling in heavy industry refers to the processing of semi-finished material without any heat treatment. Cold rolled roll sheet metal raw material is an example of this process.
Cold-rolled Steel Roll
It is the cutting and other treatment of steel roller sheets of certain sizes without exposure to any heat treatment. Cold rolling process gives more quality to steel raw material due to its structure.
Cold-rolling Technology
Raw materials are primarily processed in hot coils. Then the acidification process is applied. The acidification process is carried out for the purification of all dust or dirt on the surface of the raw material.
Then the edges of sheet products are cut and lubricated. After this process, the reversible is thinned in the machine in a forward and backward direction. In addition, cooling is carried out in these machines. Thus, smoother edges and surfaces are obtained according to the processes in hot rolling coils.
Rolling is carried out in places called cold rolling mills. Material is placed in the conveyor belts of the raw material here. The material is rotated in the appropriate ways. The raw material that passes through the shaper rollers becomes a roll.
All rolling is carried out through computers. All data are available in the computer in order for the steel raw material to take shape in line with the rolling process. In addition, steel raw materials are processed according to rolling ranges.
Thanks to rolling rollers with a very high torque value, flat steel raw material is finalized.
Cold rolling is completed in several different machines and the material is shipped to the storage places in rolls.
Rolls weighing 5 tons each are shipped from the warehouses to the areas of use on order.
What Are The Features?
Roll sheet is rolled in three groups:
- In hot coils with rolls; slitting, edge and height cutting operations are applied.
- Acidification and annealing process is applied to the raw material in hot coils. In addition, the process called tempering can be applied. This method is one of the types of cold rolling.
- The surface of cold coils is covered with substances called tin or chromium.
They are produced in accordance with domestic and international standards. They have a thickness ranging from 0.25 millimeters to 3 millimeters. They are treated according to the wishes of the customer. The customer may want to perform some transactions themselves.
They are produced with a stacking weight of at least 2 tons and a maximum of 26 tons.
Quality checks are carried out by experts and some machines. They are produced in batches. They are quite light and durable.
Where To Use?
It is a highly in-demand material in heavy industry. In addition:
- It is used as a raw material in the production of some parts of automotive in the automotive industry.
- In the production of panel radiators,
- Steel pipe and profile pipe construction,
- In the furniture industry,
- In the making of white goods,
- As raw material in construction and building materials,
- As raw material in the manufacture of metal molds,
- In some parts of construction structures
They are widely used.
Advantages of Using Roll Sheet Metal
The roll sheet metal is durable and very useful in its structure.
Cooling or oxidation is not applied in the production of cold rolled roll sheet metal. Thus, a better surface is obtained. In addition, the tolerance range is higher.
Lubrication of cold rolled roll sheet product can be done easily. Due to the manufacturing feature, the strength increase is higher. The size tolerance is higher than other raw materials.
Thanks to the cold rolling method, the thickness of the sheet metal can be produced in very thin sizes. The important thing in the cold rolling process is the cooling and lubrication process. After carefully performing these operations, the raw material is shaped with the help of rollers.
Then the cold rolling process is completed.
