Direct reduced iron composition for sale

direct reduced iron composition (DRI), also known as sponge iron, is formed by the direct oxidation-reduction of iron ore (in the form of lumps, pellets or aggregates) to iron by a reducing gas or carbon element produced from natural gas or coal. Many minerals are suitable for direct regeneration.

Direct reduced iron composition properties

Direct reduction refers to solid state processes that reduce iron oxides to metallic iron at temperatures below the melting point of iron. Reduced iron gets its name from these processes, such as heating iron ore in a furnace at temperatures above 800 to 1,200 degrees Celsius (1470 to 2190 degrees Fahrenheit) in the presence of a synthetic gas reducing agent, a combination of hydrogen and carbon monoxide. .

The production of direct reduced iron and the subsequent operation of this method was the first method to obtain iron in the Middle East and Europe, where it was used at least until the sixteenth century. There is evidence that the flower method was also used in China, but China had built explosive furnaces to obtain cast iron up to 500 BC.

The advantage of the pure iron furnace method is that the iron can be obtained at a temperature of less than the furnace, only at about 1100 یا C or approximately. The problem with blast furnaces is that only small quantities can undergo construction at the same time. what is reduced iron chemical formula? what is sponge iron testing process?

Direct reduced iron composition properties

Direct reduction processes are divided into almost two categories: gas-based and coal-based. In both cases, the purpose of this process is to expel the oxygen present in various forms of iron ore (rock, concentrate, pellet, mill scale, furnace dust, etc.) so that it can convert the ore into metallic iron without melting it. Slow down. (Below 1200 degrees Celsius (2190 degrees Fahrenheit)).

The direct reduction process is relatively efficient. Steel made using direct reduction requires a significant amount of fuel, because a traditional blast furnace is not required. Direct reduction is usually done using electric arc furnaces made of steel to use the high heat generated by the direct reduction product.

Purchasing direct reduced iron composition

In modern industry, direct reduced iron processes have been developed to specifically address the problems of conventional blast furnaces. Direct regenerative iron is successfully produced in various parts of the world, making it possible to produce specialized iron and steel products in a decentralized manner (separately with the older model of the so-called “steel complex” furnace). Primary investment (CAPEX) and operating costs (OPEX) are lower direct reduction plants than integrated steel plants, and are more cost-effective for developing countries where high-grade coal coke production is limited, although steel waste in general. Available for recycling.
