Applications of Electric Actuators in the Modern Steel Industry
1. Extreme Operating Conditions, Immense Challenges:
High Temperature and Humidity: In processes such as coking, sintering, and ironmaking, equipment is constantly exposed to intense thermal radiation and steam corrosion.
Pervasive Dust: Areas such as raw material yards and blast furnace tapholes feature high concentrations of airborne dust, necessitating equipment with exceptionally high ingress protection ratings.
Vibration and Shock: During stages such as raw material conveying and steel rolling, equipment must withstand continuous mechanical vibration.
2. Precise Control, Stringent Requirements:
Precise Flow and Pressure Regulation: In gas recovery, cooling water systems, and combustion control, precise and continuous regulation of media flow is essential to achieve optimal process conditions and maximize energy efficiency.
Reliable Positioning, Safety First: In critical applications-such as emergency shut-off and safety venting-actuators must respond rapidly and position themselves with absolute accuracy; even a millisecond-level failure could trigger a major safety incident.
3. Continuous Production, Stability Paramount:
Steelmaking is a continuous-process industry; any unplanned downtime results in massive economic losses. Consequently, actuators must demonstrate extraordinary reliability and longevity to minimize failure rates to the absolute minimum.
