3. Overview of the MIDREX Process Fig. 4 and Fig. 5 show, respectively, the flowsheet for the standard MIDREX Process (MIDREX NGTM) based on natural gas and an exterior photograph of the plant (Tosyali Algérie Steel Mill in Oran,charged at the ambient temperature from the top of Algeria). The MIDREX NG consists of two main
Midrex provides each plant a detailed safety manual, and our employees go through rigorous safety training. We investigate all incidents, large or small, to identify causes and pinpoint potential hazards so corrective actions can be taken to ensure that every MIDREX Plant is as safe a working environment as possible.
Part 2 will present a strategy for increasing the percentage of lump ore in the feed mix of a MIDREX Plant, which involves MIDREX Remote Professional Services (RPS). A step-by-step case study will document the method used to adapt to …
With an eye toward the future, Midrex Technologies and Primetals Technologies can produce high-quality HBI with the most environmentally friendly technology for ore-based iron-making. The natural gas-based MIDREX® Direct Reduction Process releases 50% fewer carbon emissions than blast furnace ironmaking. Combine this technology with green ...
The FMO MIDREX Plant in Venezuela uses a steam reformer, and H 2 /CO has varied from 3.3 to 3.8. There are also six MIDREX Modules that utilize gas made from coal, and these have H 2 to CO ratios from 0.37 to 2.0. Thus, the MIDREX Process has successfully produced DRI at H 2 /CO ratios from 0.37 to 3.8.
Previous point number 1; i.e., the theoretical statement that MIDREX Process is designed with safe gas velocity margins for 2mm particles, is confirmed by a particle size analysis carried out on sample collection at the process classifier …

share) were produced by MIDREX Plants in this period. Natural gas is generally the main source of reducing gas in shaft furnace-based processes, and DRI produced using natural gas has significantly lower CO 2 emissions than DRI produced using coal (directly or indirectly). In 2023,
The 1.6 million metric tons/year plant, based on MIDREX® NG Process technology, will be one of the world's most modern and efficient ironmaking production facility when it begins operation in summer 2020. It will provide a domestic source of high quality ore-based metallics for electric arc furnace steelmakers in the Great Lakes region.
THE HEART OF THE MIDREX® PROCESS IS THE MIDREX® SHAFT FURNACE. AS A KEY COMPONENT OF THE MIDREX® DIRECT REDUCTION PROCESS, THE MIDREX SHAFT FURNACE IS THE MOST FLEXIBLE AND VERSATILE REDUCTION VESSEL FOR DRI PRODUCERS. The MIDREX® Shaft Furnace can use natural gas or a syngas from coal or …
Bustle Temperature. In a MIDREX Plant, it is preferable that the control of the bustle temperature is operated in automatic mode. The operating criteria of the bed temperature in combination with the process gas flow/ton ratio is used to maintain the bed temperature at an optimum and stable value (+/- 10°C) to ensure product quality and process stability.
In 2018, Midrex approached Nu-Iron with a proposal for a suite of services that included the ability for Midrex's engineering personnel to observe the operation of Nu-Iron's plant remotely from their RPS control room in Charlotte, NC. …
KSL's relationship with Midrex began almost 10 years prior to KSL becoming the owner of the MIDREX ® Direct Reduction Process and Midrex Corporation, as the company was then known. In 1974, Kobe Steel Ltd. (KSL) and a Japanese trading house entered into a joint venture with the Government of the State of Qatar to create Qatar Steel Company (QATAR STEEL) as the …
Some companies building direct reduction plants, such as Cleveland-Cliffs Inc, which has announced plans for a 1.6 million t/y HBI plant using MIDREX® Technology, have their own iron ore resources. Others are considering blending BF and DR-grade pellets or even having a new pellet designed.
