Coolant Scrap

Continuous inflow of dense and homogeneous scrap

Refractory scrap plays a crucial role in the steelmaking process—both in primary metallurgy (BOF) and in secondary metallurgy. The latter requires refractory scrap with a defined chemical composition, high bulk density (≥ 2 t/m³), and a large surface area—ideally in spherical form.

Cooling scrap is typically produced from production scrap with a known chemical composition. With the EcoShred® Vertec, SICON offers a vertical shredder specifically designed for this application, which produces cooling scrap of ideal quality for steel mills.

The feed material is gradually spheroidized across four grinding levels. The geometry of the stator and rotor components is individually adapted to the respective feed material. Optimal design can be achieved with the help of simulations and test facilities. SICON naturally also handles the appropriate material feed and the downstream process—including dust removal. Here, too, individual adaptation to customer-specific requirements and the desired end product takes place.

For steel mills, the homogeneity and flowability of cooling scrap are of central importance. The EcoShred® Vertec with downstream dust-free special screening ensures that these requirements are met—and does so with a high degree of automation that eliminates the need for an operator.

Feeding to the vertical shredder

SICON develops your scrap metal processing project from the initial concept through to the completion of the entire plant. Of course, we are also happy to apply our expertise to retrofits and optimizations.

Coolant scrap at its best - dense and homogeneous material

EcoShred® Vertec systems typically use rotors with grinding rings for the production of cold-rolled scrap. The systems are customized to meet the operator’s specific requirements. By tailoring the overall system design to the customer’s needs and the desired output material, optimal end-product quality is ensured.
