2017-10-27 · and productive Direct Reduction Technology Designed for Today, into the top of a cylindrical, refractory-lined vessel, where it descends by gravity flow and is contacted by upward flowing reducing gas. The reducing gas, which is primarily hydrogen dictate the type of feed materials used within the DRI plant.
2018-8-4 · The Labuan HBI plant has a rated capacity of 900,000 tons HBI per annum. During the time before China’s dumping of export steel, the plant used to operate at 92% of its capacity at 825,000 tons per annum (refer table in annual reports and TheStar news in 2004 provided below):
HBI is made by compressing DRI discharged from the MIDREX® Shaft Furnace at 5 DRI Products & Appliions DRI reduction in electrode and refractory >>Online; Foundry Products + Equipment Karrich. This silicabased refractory is designed for lining coreless induction furnaces.
2018-12-4 · The new plant, the largest and most modern plant of its type in the world, covers an area of two square kilometers. The plant’s own deep-sea port can currently handle five million tonnes of material each year (3 million tonnes of iron ore pellets and 2 million tonnes of HBI).
internal stakeholders. To continue to operate the plant without a “Strategic Refractory Management Plan” will prove to be very costly and unsustainable. 8 Acknowledgements The authors gratefully acknowledge the assistance of the staff at the Port Hedland HBI plant.

Output from the PERED direct reduction plants can be in the form of (i) cold direct reduced iron (CDRI), hot briquetted iron (HBI), coination of CDRI/HBI, HBI/hot direct reduced iron (HDRI), and CDRI/HDRI. PERED technology is an improved energy efficient technology
2017-11-18 · Hot Briquetted Iron (HBI) is a denser and compacted form of DRI designed for the ease of shipping, handling and storage. DRI can be used in steel units where the DRI reduction unit is situated at the site of the steelmaking plant.
It facilitates tapping at lower temperature, which in turn increases production and refractory life of melting equipment and reduces power consumption, thereby reducing the cost of steel making. ERF provides greater flexibility to steel maker in overall plant operation.

2010-9-29 · processes or new types of refractories. History reveals that refractory developments have occurred whereas basic refractories can be best used in contact with a basic chemical environment. Actually, believed to offer the best possibility for a clear understanding of the origin and nature of steel plant refractories.
2018-12-7 · A refractory material or refractory is a heat-resistant material, i.e. a mineral that is resistant to decomposition by heat, pressure, or chemical attack. It most commonly refers to a mineral that retains strength and form at high temperatures .
The establishment of a Strategic Refractory Management Plan, resulted in a significant increase in refractory life at the Port Hedland HBI plant, and a corresponding decrease in refractory management costs. A mathematical modelling study was carried out as part of this plan. The finite element
