Mission

Romania's leading seamless pipe producer.
Two facilities. One production chain.

Tenaris Silcotub is the leading Romanian producer of small diameter seamless steel pipes, serving the mechanical, automotive, oil & gas, chemical and petrochemical, and power industries.

The company operates two manufacturing facilities across Romania: Zalău — seamless pipes manufacturing with an annual production capacity of 180,000 tons, and Călărași — steel making with an annual capacity of 470,000 tons.

The Zalău plant produces seamless tubes and pipes with outside diameters ranging from 8 to 146 mm in carbon and low alloy steel.

The Călărași steel shop includes an electric arc furnace, a ladle furnace, and continuous casting equipment. With a production average of 90 tons/hour, the facility's key equipment includes:

      Călărași production data: Electric arc furnace — 100 MVA transformer power; ladle furnace — 50 MW transformer, 100 tons nominal capacity (90 tons liquid steel per heat); continuous casting machine — round bars Ø 148–260 mm, rectangular blooms 350×260 mm.
    

Solution

Four LPR cameras.
Full weighing automation & SAP integration.

Dozens of trucks enter and exit the Călărași facility every day. The client needed an accurate database of incoming vehicles, cargo, and weight — integrated directly with their internal ERP (SAP).

The goal was to automatically capture license plates of trucks on the weighing system and feed that data into SAP, eliminating the possibility of fraud and ensuring exact inventory tracking.

Two heavy-duty industrial weighing stations were installed — one at entrance, one at exit. Each truck entering the plant is weighed to determine the quantity of metallic waste to be melted and transformed into pipes.

Each weighing station is equipped with 2 Mobotix M24-LPF LPR cameras: one captures the trailer's license plate, the other captures the tractor head's plate (which can differ from the trailer's). Metrici LPR also supplied low-pass filters for improved IR detection. All 4 cameras connect to a Metrici Towersys 110 server.
