Product Introduction of Special Hydraulic System for Metallurgical Machinery
**Product Name**: METAL-HYDRO™ Series of Hydraulic Power Solutions for the Metallurgical Industry
**Application Fields**: Continuous casting machines, rolling mills, forging presses, blast furnace top equipment, scrap steel processing, etc., in high-temperature and high-pressure metallurgical conditions
---
### **Core Competitive Advantage**
**Extreme Operating Condition Adaptability**
- **High Temperature Resistance Design**: Hydraulic oil temperature can be maintained stably at 80℃ (with a 120℃ instantaneous tolerance), equipped with a forced cooling system
- **Enhanced Anti-Pollution Capability**: Four-stage filtration system (β≥1000), ensuring NAS 1638 Class 8 cleanliness level
- **Anti-Oxidation and Corrosion Resistance**: Stainless steel valve group + ceramic-coated pipelines, resistant to steel splashing and acidic cooling water
**Reliable operation under heavy load**
- **High-pressure module**: Rated pressure 42 MPa (peak 60 MPa), meeting the requirements of ten thousand tons press machines
- **Impact-resistant structure**： Energy storage buffer + shock-absorbing support， capable of withstanding the intense vibrations during steel biting by the rolling mill
- **20，000 hours** lifespan of key components (certified by the metallurgical industry's MTBF standard)
**Intelligent Monitoring Upgrade**
- **Thermal Radiation Compensation Technology**: Automatically correct pressure drift in high-temperature environments
- **Wear Warning System**: Real-time monitoring of pump unit bearing vibration and metal particle content in the oil
- **5G Remote Maintenance**: Connect to the steel mill's MES system to generate equipment health reports
