In the fast-paced world of steel production, where precision and time are critical, ultra-fast nozzle changers are transforming continuous casting. At Steltech Makina, with over 60 years of expertise in steelmaking machinery, we deliver advanced tundish mechanisms, cranes, and transfer cars designed to maximize efficiency and safety. One of the most groundbreaking innovations is the hydraulic-driven nozzle changer, enabling seamless and rapid replacements without halting operations.
The Evolution of Nozzle Changers
Continuous casting turns molten steel into slabs or billets without interruption. Traditionally, nozzle replacement meant stopping production, leading to downtime and material loss.
With the advent of CNC-calibrated hydraulic nozzle changers, replacements now happen in 0.25 seconds or faster. Using hydraulic cylinders, accumulators, and precision valves, these systems ensure uninterrupted steel flow while eliminating the risks of clogging or misalignment.
How Steltech’s Systems Improve Steelmaking
At Steltech, we enhance this legacy with robust hydraulic solutions:
-
Speed & Efficiency: Forward strokes in 0.2–0.25 seconds minimize production losses.
-
Safety: Emergency stops, relief valves (210 bar), and monitored oil temperatures (30–50°C) protect workers and systems.
-
Precision: CNC calibration ensures micron-level accuracy, with 10-micron filtration to avoid inclusions in steel.
-
Sustainability: Less downtime and scrap reduce waste and energy consumption.
Our tundish mechanisms handle flows of up to 28 liters per minute per strand, enabling 20% higher throughput while extending casting sequences.
Commitment to Innovation
As a pioneer in Turkey’s machinery sector, Steltech Makina designs tundish mechanisms that integrate seamlessly with existing lines. With customizable hydraulics, weekly oil checks, and six-month accumulator preloads, maintenance is simple and efficient.
We complement nozzle changers with advanced systems like Carbon Multi-Point Injection for EAFs, supporting greener, smarter, and more efficient steelmaking.
Looking Ahead
The steel industry is moving toward automation and Industry 4.0, where hydraulic systems are key to zero-downtime operations. Steltech continues to invest in R&D, ensuring our clients stay ahead with solutions that combine safety, efficiency, and sustainability.
