Arvtech™ is the trademark that identifies a special line of hot rolled thin gauge steels, with an exceptionally flat cross section and close tolerances that are unique in the world.
Gauges are available down to 1.00 mm and with close tolerances of up to +/- 0.04 mm depending on the resistance level.

FROM ARVEDI TECHNOLOGY, HOT ROLLED COIL AS AN ALTERNATIVE TO COLD ROLLED

With Arvedi ESP™ technology, in 180 m and about 5 minutes, the liquid steel is directly transformed into quality coils through an in-line and continuous cast-rolling process.
The process utilizes the thermal properties of liquid steel and its plasticity at high processing temperatures, enabling the production of hot-rolled coils in thin gauges and various steel grades.
Arvtech™’s metallurgical and dimensional characteristics allow it to be used—for specific applications—as an alternative to cold-rolled products.

PRODUCT AND PROCESS CHARACTERISTICS

Process times
The integration of the casting and rolling phases allows the process from raw material to hot rolled coil to be completed in approximately one hour, with approximately 5 minutes for the continuous casting and rolling phases.

Workability
The fine grain structure and low levels of sulfides contribute to the workability characteristics of the material. The liquid heart reduction process favors the control of macro segregations.

Product uniformity
The continuous process keeps the strip tensioned during the rolling and cooling phases, contributing to flatness control. The geometric and mechanical characteristics are controlled along the length of the belt and on the transverse profile.

Customization of thickness
The narrow tolerances, combined with the possibility of rolling a personalized nominal thickness, allow the generation, for the same weight, of a longer coil than the conventional cycle one, allowing the user to minimize machine changes, increasing production yield.

Constant quality with every supply
Arvtech™ is obtained through a highly automated and calibrated process at every stage, guaranteeing consistency and repetitiveness of the material properties.
