The Iron Making Plant Project in the Union of Myanmar is the first implementation on industrial scale of the unique Russian technology – the ROMELT process – which makes it possible to process the poor iron–bearing ore without any preliminary beneficiation and to obtain a marketable product – the pig iron. As raw materials for the pig iron production the local poor iron ore of the Pang Pet deposit with the iron content of ore not exceeding 29 % and the power–generating coal of the Kye Thee coalfield are to be used.
In addition to the prime product – the pig iron – the ROMELT process allows to produce also slag for commercial use (building of roads, erection of structures) and electric power in the quantities sufficient to meet the own requirements of the Plant and to transmit the power energy into the external electric power system of the Union of Myanmar.
In preparation of the design documents of the Iron Making Plant using the Russian Romelt  process in the Union of Myanmar  with an output of 200,000 tons of pig iron annually the following organizations have participated:
  • “Lengipromez” Open JSC, the     General Designer, has executed the comprehensive designing of the main     units of the Plant, including designing of the service bins, the Romelt     Shop, Pig Casting Machine, General Works Laboratory, Repair Shop, storage     facilities, plant water supply facilities, Air Compressor Station, Gas Distribution     Station of the external energy carriers systems.
  • “Energoprojekt – Warszawa S.     A.” – comprehensive designing of the Coal Preparation Unit of the Iron     Making Plant.
  • “Mekhanobr Engineering Co.” – comprehensive     designing of the Ore Sizing and Beneficiation Plant.
  • RUP “BelNIPIEnergoprom” –     comprehensive designing of the Waste–Heat Recovery Electric Power Station     (WHRPS).
  • “Tyazhpromelektroprojekt Ltd” –     designing of the Plant electric power supply system.
The ceremony devoted to the first stage of commissioning of the Iron Making Plant to-be-constructed according to the innovative Russian technology “Romelt” took place on October 21, 2015 in the Union of Myanmar. Construction is being carried out within the contract signed by the Myanmar Economic Corporation and the Joint Stock Company Foreign Economic Association “Tyazhpromexport” included into the “Rostec” State Corporation.
The unique technology “Romelt” represents a single–stage process of the iron smelting from various iron–bearing materials by means of their liquid–phase reduction using the power–generating coal, without use of coke and preliminary preparation of the iron–bearing burden material. Actually, this is a noblastfurnace practice of iron production from iron ore. For the first time this technology was tested at the Integrated Iron and Steel Works in Lipetsk and in Kazakhstan.
