Production Process
Production Process
Thanks to state-of-the-art machinery, Siderscal is able to process slabs of various lengths and thicknesses with maximum precision through a hot-working process, thus offering its customers customized products tailored to their production needs.
The Siderscal production process consists of several stages to ensure quality and performance:
Slab reheating furnace: Initial heating for material processing.
Descaling: Removal of surface impurities for greater purity.
Rolling: Defining the required thickness.
Flattening/Stress relieving: Improving the material’s flatness and stability.
Normalization: Final structural homogeneity and mechanical strength.
This process meets the most stringent requirements of the steel industry and complies with current regulations.
Production Steps
Furnace and Descaling
The process starts with a 30-ton steel slab, cut according to production orders to obtain semi-finished products. These are preheated to a temperature of 1200°C, preparing the material for subsequent operations. After leaving the furnace, the semi-finished products are automatically transferred to the rolling mill. Before this step, the slabs are treated with high-pressure water jets to remove any remaining impurities, ensuring a clean surface for rolling.
Rolling Process
Rolling is a fundamental mechanical process for the production of HP re-rolled flat products, reducing the material thickness to meet the required specifications. During this stage, the material passes between two opposing cylinders that, while rotating, compress the semi-finished product to achieve the desired thickness. The process may involve multiple passes, with progressively closer rollers, to reduce the friction generated. This precaution is essential to avoid energy dispersion and ensure an optimal result.
Shearing and Leveling
Once the desired nominal thickness is reached, the sheet undergoes the shearing or trimming phase, which involves a transverse cut to obtain the lengths specified in the production order. Regarding edge trimming, only certain plants have lateral blades to cut the material longitudinally; generally, re-rollers perform this operation later on a cutting table. In the absence of edge trimming, the sheet has a rough edge. Leveling follows the same process used for coils, eliminating the residual internal stresses of the sheet after rolling and ensuring a uniform surface.
