What is the Composition of Sintered Iron? 4 Key Components Explained

Sintered iron is a material that is made by combining several key components. These components undergo specific processes to form a solid mass.

4 Key Components Explained

What is the Composition of Sintered Iron? 4 Key Components Explained

1. Iron-Containing Raw Materials

Iron-containing raw materials are the primary ingredients in sintered iron. These materials include ore powders, iron concentrate, blast furnace dust, rolled steel, and steel residue. The particle size of these materials is usually less than 5mm. The quality of these raw materials is very important because it directly affects the iron content and purity of the final product.

2. Fluxing Agent

The fluxing agent is another crucial component. It often contains high levels of valid CaO. This agent helps in the sintering process by removing impurities and improving the quality of the sintering ore. An example of a fluxing agent is white limestone, which introduces MgO into the sintering ore, enhancing both the process and the final product quality. The fluxing agent should have stable ingredients and a particle size of less than 3mm.

3. Fuel

Fuel is essential for the sintering process. The primary fuels used are coke powder and anthracite. These fuels are chosen for their high fixed carbon content, low ash and volatile content, and low sulfur content. The stability of the fuel's composition and a particle size of less than 3mm are crucial for consistent sintering.

4. Sintering Process

During the sintering process, these materials are mixed with water and undergo physical and chemical transformations. This includes transient and permanent liquid phase sintering, where the materials fuse together. This filling of any open pores or cracks with liquid substances or binders results in a solid, dense mass.

The sintering of iron ore powder aims to utilize resources comprehensively, remove harmful impurities, recycle beneficial elements, and improve the metallurgical performance of the ore. This process is crucial for efficient iron production, environmental protection, and resource conservation.
