The metallurgical industry operates under harsh conditions, facing challenges such as high temperatures, excessive dust, and heavy loads. Pneumatic components, with their ability to withstand harsh environments, have become core components for process control and safety assurance. In the blast furnace ironmaking process, pneumatic actuators precisely control the distribution valve and the inclination Angle of the chute, adjust the uniformity of the charge distribution, ensure sufficient reaction inside the blast furnace, and enhance the ironmaking efficiency. In converter steelmaking, pneumatic components control the lifting of oxygen guns and the opening and closing of hoods, adapting to the smelting rhythm in high-temperature radiation environments. At the same time, they drive the valves of the ventilation and dust removal system to switch rapidly, efficiently purifying flue gas and reducing dust pollution. During continuous casting production, the pneumatic cylinder drives the mold vibration device, ensuring the quality of the cast billet through stable reciprocating motion and avoiding defects such as cracks and slag inclusions. In the steel rolling production line, pneumatic components control the clamping of the rolls and the start and stop of the conveying roller track. In combination with the hydraulic system, it ensures smooth operation under heavy load conditions and guarantees the dimensional accuracy of the steel. In addition, the safety interlock function of pneumatic components can quickly cut off the power when the equipment malfunctions, ensuring the continuous and uninterrupted operation of the metallurgical process. Meanwhile, its wear resistance and corrosion resistance can meet the long-term high-intensity operation requirements of the metallurgical industry and reduce maintenance costs.
