Hot Rolling Technology
Hot Strip Mill Technology System Integration
With so many projects references in HSM field, CISDI has accumulated abundant experience and technical advantages in EPC, EP, independent system integration and overall technical responsibility etc. with mastering a large number of proprietary technologies, ensuring that the product quality is up to the internationally advanced level.
Flying Crank Shear
The largest flying crank shear in China which was designed by CISDI is able to cut high-strength pipeline steel API5Lx100 of 60mm(thickness)x 2,150mm(width), facilitating the hot tandem rolling of high strength steel.
Hydraulic Servo System for Hot Strip Mills
CISDI has developed its fully proprietary hydraulic servo control system for large hot tandem mills through 1,750mm hot strip mills of Xinjiang Bayi Steel and Tiantie; the successful implementation of this technology in high-level large HSMs has filled the gap in this field in China.
Efficiency Laminar Cooling Device
The patented efficiency laminar cooling device of CISDI is composed of intensified cooling zone, micro zone and trimming zone. With max. cooling intensity of 170m³/(m²xh), it can provide cooling in various patterns to adapt to micro-alloy high-strength steel, high-strength steel with ultra-fine grain, DP, TRIP and MS rolling.
Skin Pass and Coil Dividing Line
CISDI has successfully developed the leading skin pass mill technology and a collection of skin pass line including 1,450mm, 1,500mm,1,580mm, 1,750mm, 1,780mm,1,880mm, 2050mm and 2,250mm. The skin passed strip can have tensile strength up to 1,200MPa. CISDI has supplied over ten such skin pass lines so far.
The most powerful fully-hydraulic downcoiler in China which was designed by CISDI can provide coiling for high-strength pipeline steel API 5L X100 of 20mm (thickness) x 2,150mm (width).
Air Mist Cooling in Heat Treatment
CISDI developed the innovative air mist cooling plant for plate heat treatment.
