BRIEF ABOUT THE FURNACE AND TECHNOLOGY

Mazanasu furnace series is currently available in 0.5 to 3 tn capacities, for pilot projects; 15, 30, 100 and 200 tn furnaces are under planning. According to estimates we will be able to deliver a 200 tn furnace in 2029, its design will already start in 2026. Furnaces are tailor made for the application required. Different metals like iron, nickel, copper as well as ores and metal containing waste materials can be processed to required metal products. For example iron based industry can consider to use new type of raw materials; bauxite residue, ilmenite, iron ore, blast furnace sludge and dust, slag, mill scale – all these can be used to make: iron, steel or super cast iron SCI© It is notable that for example.

It is also possible to make different structure material: Bainite can be made without environmental harmful chemical treatments in simple processing – notable is that structure in 100% bainite, without the impurities when made classical methods. 100% Matrix and Perlite structures are also possible. Carbon, Phosphorus and Sulphur content can be reduced to 0.001% level directly in Mazanasu furnace.

"Green Steel. With our technology and our furnace, you can melt iron ore concentrate directly, which means that CO2 emissions are 95% lower than in current blast furnaces (is practically emission-free) and electricity consumption only 1/4 of current blast furnaces. Compared to hydrogen technology, the need for electricity is minimal."

Technology offered is totally new, this is world’s first direct reduction furnace. Iron recovery from raw materials is not based on carbon usage to bind with oxygen, but the metals are released from oxides directly. (small amounts of carbon is used to accelerate the process, accelerating the process and we like to call it intensifier). This competes with steel production with hydrogen technology (the only other technology not using carbon as principal process to remove oxygen from iron oxides as main process.) Hydrogen technology route requires 10 x more energy, and the green steel – is very much depending on how the electricity is produced. It must be also noted that hydrogen plant must be build, as well as the extra power supply capacity. Mazanasu technology is using less electricity than normal furnaces. (In case of mill scale – if it contains oil – oil can replace part of the carbon required.)

"When our furnace is smelting, a magnetic field is created in the furnace, when adding moist materials in there, it creates a hydrogen plasma, which accelerates the process."

To demonstrate the effect for the emissions, when processing 1 ton of steel and iron scrap in classical EAF, typically 62 kg CO2 is put out in furnace process, Mazanasu SPAF releases 1.38 kg. Classical EAF “loses” 15 kg iron in form of Fe2O3 with smoke, Masanasu SPAF “loses” 16 grams only. Mazanasu technology is the most cost effective way to make “green steel”.

Also attached an article of slag working as carbon trap – interesting possibility to use slag in two stages first as carbon trap – then process it further usage (where carbon is not released).

This technology opens also an option to use alternative raw material sources, like red mud and ilmenite – this can be a good option if proposed restrictions or tariffs for US and EU scrap exports come to affect.
