HOT ROLLING

In CAESA we produce hot rolled special profiles with a maximum width of 110 mm for all type of sectors and industries. These profiles are always produced according to the drawings and the specific needs of each customer.  

We exist since 1946 in the steel transformation sector, and we have a long national and international business experience. We know exactly the current demands of the different industry sectors and we offer tailor made solutions.  

In order to produce the profiles in an accurate and efficient way, we have an expert design and technical team, a laboratory, our own tool development and innovating machinery as well as specialized production lines. 

Hot rolled profiles in steel

Our delivery dates are adjusted and adapted. In order to be able to prepare a feasibility study, we need to know the following items: 

  • Drawing of the profile to be produced. 
  • Steel grade required. 
  • Annual consumption. 

Our team also offers specialized advice for each customer, as also recommendations when producing the steel profiles.  

Hot rolling process

The hot rolled profiles are obtained from a steel raw material, square shaped, called billet. 

After cutting this raw material to a specific length, it undergoes a warmup process in the oven at high temperatures, then it is descaled with water pressure and later deformed with different passes through several casting tools in our hot rolling lines until we reach the desired final shape. This profile is cooled down and then straightened and cut to the wished length of the customer and finally deburred. 

Tailor made profiles can be obtained in different lengths, dimensions and shapes.  

Once we have the product required by the customer, we also offer other processes like the saw cutting into pieces or the shot blasting to improve the surface appearance of the hot rolled product. 

Hot rolled profiles advantages

The use of special profiles offers benefits and advantages to the customer. 

Main competitive points of the use of special profiles versus standard materials:  

  • Reduces the customer processes, lowering its costs:  
  • Materials designed according to the customer requirements (Steel grade, shapes, lengths…)  
  • It improves the customer’s productivity, reducing the machining processes, the tool wearing and consequently their costs. 
  • Lower raw material costs as with special profiles, less Steel is used than with simple standard material (rounds, squares, flat bars, among others). 
  • Personalized design, unique profiles for each customer.  

High resistance

High quality Steel.

Economics

As less quantity of material is needed in order to obtain a concrete shape.

Different shapes

When heating up the carbon steel, it can be handled in a different way and get concrete shapes.

Used machinery for the hot rolling process

At CAESA we bet on innovation and the development using precise equipment and applying continuous improvement systems.    

With this target we count with the following machinery park:  

  • 2 shears and 2 saws for cold cutting billets up to 150mm.  
  • 1 pusher furnace for billet heating with 10 mt/h capacity.  
  • 1 galloping furnace for billet heating with 10 mt/h capacity. 
  • 1 billet roughing train for dimensions up to 150mm.  
  • 3 hot rolling lines with 280mm between centres.  
  • 2 cutting and straightening lines.  
  • 1 straightening machine.  
  • 2 deburring lines. 
  • 4 disk saws for cutting pieces and bundles.  

Shared machinery with the cold drawing process

Some facilities and processes are also used in both technologies, hot rolling and cold drawing.  

  • 10 bridge cranes with a capacity between 5 and 10 mt.  
  • 2 design and tool machining equipment (CAD/CAM).  
  • 3 CNC Turning machines for tool construction.
