Direct reduction ironmaking is a process that produces sponge iron through solid-state reduction below the melting point of iron ore. The product is named for its porous structure, with low carbon and silicon content, and composition similar to steel, often substituting for scrap in electric arc furnace steelmaking. This process uses hydrogen or carbon-based reducing agents to directly reduce iron ore, yielding sponge iron and metallized pellets. The direct reduction furnace-electric arc furnace steelmaking route simplifies operations and reduces energy consumption

Rotary dryer is a drying device, widely used in mining equipment. It can be divided into two categories, direct and indirect heat transfer drum dryers.

Cooling machine is the main supporting equipment in rotary kiln production system which has simple structure, stable performance and reliable operation. The waste gas after heat exchange will be imported into rotary kiln so as to improve the thermal efficiency of the whole system.

 

1) Rotary kiln is the Thermal Equipment, heating materials, in cement industry for calcining clinker.   
2) It is also used in various industries, such as cement, nonferrous metallurgy, ferrous metallurgy, chemistry, building, refractory material, environmental protection, etc.
