Direct reductioniron export industry

Ore is introduced into blast furnaces along with coke (as a reducing agent). The molten material will then be injected into oxygen furnaces to make steel and remove impurities. Coal is also required for the production of coke, which must be supplied and produced by coke. For more information on direct reductioniron Iron Export Industry, visit our website.

The brief introduction to direct reductioniron

In the direct method, which is a newer technology, electric arc furnaces are used to make steel. This method uses natural methane (CH4) to reduce iron ore instead of coke. Of course, it should be noted that this issue is relevant and beneficial only in countries like ours, which themselves benefit from the rich resources of natural gas. Otherwise, the purchase of gas in other countries will be unprofitable for the implementation of this technology.

Our rich country, having discovered these resources and created global networks to transfer them to related industries, was able to implement a direct method for the steel industry. The two most common and practical methods in the direct resuscitation process are Midrex and HYL, the first of which is common in Iran. In this method, carbon monoxide and high temperature natural gas are introduced into a tank containing pellets. The hydrogen in methane reacts with the desired oxygen in the iron oxide, and by releasing water vapor, the iron is purified to a higher degree.

This product is called sponge iron, which is used together with scrap metal for loading into various smelting furnaces and steelmaking. Melting furnace Basically, two types of furnaces are widely used for this purpose: electric arc furnaces and induction furnaces. The furnace is first charged with scrap metal, and then the sponge iron obtained in the previous steps is added to the molten scrap. The ratio of sponge iron used to scrap in both furnaces will be 3: 1. At the end of the smelting process, the resulting molten steel is loaded into electrolyzers.

Continuous casting At this stage, the molten steel, after chemical decomposition, is sent from the inside of the baths to the steel ingot molds. A stream of water lowers the temperature of the molds, cooling their walls. This decrease in temperature leads to the formation of a thin shell around the ingot in the solid phase. Then spraying water on the steel inside the molds will drastically reduce their temperature and harden. For more information on direct reductioniron suppliers visit our website.
