Making Procedure and Application of Hot Rolled Steel

Most engineers often face the pertinent question of picking the correct metal to work with. Hot rolled steel, one of the types, constitutes steel being rolled at temperatures as high as 1700 degrees Fahrenheit. This kind of steel is malleable and can swiftly transform into the shape one requires. It is also ductile and tough.

When purchasing hot-rolled sheet metal, one should go for reliable and trusted manufacturers like JSW HotRolled steel. The products have a thickness of up to 25.4mm while a width of up to 2050mm. 

Properties:-

● Easy to produce in large quantities.

● The market price is lower compared to other steels.

● Due to the normalizing procedure, it can be easily modified into required shapes.

Making Procedure:-

The procedure in which the steel is rolled at high temperatures is known as hot rolling. The temperature is kept more than the steel’s recrystallization temperature. This allows one to mold them into larger shapes without much difficulty. However, when this gets cooled, the sheets do not shrink consistently.

● At first, billets or steel slabs are cast from hot liquid metal.

● These slabs have to be then fed into the reheating furnace. These slabs are conditioned in the furnace. 

● It is heated at a temperature of about 1700 degrees Fahrenheit. 

● The following process is known as roughing. The slabs whose surface share has been eliminated in the earlier procedure are treated here. Due to the high temperature of the steel, these can be flattened into large sheets with rollers. These are rolled into rolled materials by a roller with the required width, thickness, and shape. 

● In the next step, finishing rolling, the main task is to modify the shape and create an even surface of the rolled material. Thus, billets get cut into the necessary sections and dimensions before cooling.  

● After passing through the finishing mill, these strips or rolled materials are produced at the round-out table. They are coiled here. As the strips get rolled, they are sprayed with water. This ensures that the strips have cooled down to the necessary temperature for coiling.

Applications:-

The hot rolled steel, which is made from the hot formed steel, has various uses and applications in modern industries. This kind of steel is the best choice when tolerance is not a priority. It is also an economically sound option. Due to its properties of being pliable and tough, it is used in fields where the precise shape of the material is not required. Some of the applications are:-

● Railroad tracks: A railroad track must be tough and strong, especially when large passenger and goods trains travel above it daily. Thus, they are made from hot rolled steel, which gives them the characteristic of being tough.

● Structural Section: These are used in the creation of steel structures. Structural sections do not need a particular shape, making hot rolled steel the correct option.

● Tanks

● Guardrails

● Pipes and Tubes

● Construction

● Truck Frames

● Light Poles

● Gas Cylinders

● Shelving

Hot rolled steel manufacturing procedure is comparatively less complicated, and its use in the market is numerous. This makes it one of the most sought-after metals, and one should trust only reliable manufacturers like JSW HotRolled steel while buying.
