Eletrotherm’s In-Line induction heating system for hot rolling/ reheating of bars, billets, slabs, plates, and blooms. Our heater provides temperature control and uniform heating from the surface to the core and head to tail of the product. Our heater is highly efficient and compact; available in frequencies between 250 Hz to 1000 Hz. and power between 500 kW to 10000 kW. Hot rolling is used to form thinner pieces of metal by using heat.
This process is mainly used to change the shape and thickness of metal. The starting material is usually large pieces of metal, like semi-finished casting products, such as slabs, blooms, and billet.
If this product came from a continuous casting operation the products are fed directly into the rolling mills at the proper temperature. Steel slabs or billets are first heated to an extreme temperature, which is slightly above the metal’s recrystallization temperature, and then they are sent through rollers that can be programmed to apply a controlled amount of pressure to form the metal into the desired size or thickness.
Hot rolling is used mainly to produce sheet metal or simple cross-sections such as rail tracks. Other typical uses of hot rolling are to produce TMT bar, angle, channel, I-beam, and wire rod.
