Direct Reduced Iron Briquetting Machine


To understand the direct reduction iron briquetting machine, it is necessary to understand what the direct reduction iron is and the role of the briquetting.

The proportion of non-metallic materials and non-ferrous metals used in steel has increased, resulting in a continuous decline in the quality of scrap. As the raw material of electric furnace steel, scrap steel has great fluctuations in chemical composition due to its different sources, and it is difficult to master and control, which brings great difficulties to electric steelmaking. If a certain proportion of direct reduced iron (30-50%) is used as a diluent, it can not only increase the uniformity of the steel, but also improve and improve the physical properties of the steel, so as to achieve the purpose of producing high-quality steel. Therefore, direct reduced iron is not only a substitute for high-quality scrap, but also an indispensable high-grade raw material for producing high-quality steel. In recent years, due to the development of small-scale, lightweight, functional, and composite steel products, non-metallic materials in steel The increase in the proportion of use with non-ferrous metals has led to a continuous decline in the quality of scrap.

In the industry, there are many iron and phosphorus reduction methods, iron concentrate powder reduction method, etc., that is, rolling iron oxide phosphorus or concentrate powder is pressed into a block by a reduced iron briquetting machine, and then charged into a roasting tube to be calcined in a kiln to produce Out of high quality reduced iron. The directly reduced iron is broken (breaking the directly reduced iron ingot into a block) and broken (the block direct reduced iron is broken into particles of 0 to 15 mm), and then magnetically removed to remove SiO2, CaS and free carbon. And other impurities. The user can again use the reduced iron briquetting machine to suppress the direct reduced iron particles, so that the directly reduced iron particles are molded and reach a certain pile specific gravity g/cm3 requirement. The direct reduction of iron broken particles directly affects the physical properties of the compact (compressibility, formability, heap specific gravity g/cm³) and plays a vital role in the production of special steel.

Features of reduced iron briquetting machine

1、This machine adopts hydraulic transmission, highly professional integral valve block, and large flow diameter, which reduces the pressure loss of the system and eliminates the drawbacks of leakage.

2、The use of cartridge valve, electro-hydraulic proportional valve and unique oil circuit design make the hydraulic system perfect. Even if it works under long-term heavy load, the system will not appear to be inadequate.

3、The system is designed with a pre-discharge device, which completely eliminates hydraulic shock.

4、Advanced rapid device to ensure the production needs of users.

5、The electrical part adopts imported PLC automatic control system, which has strong anti-interference ability and low failure rate.

6、The body adopts an integral steel structure with high strength and good stability, and no anchor bolts are required.

To understand the direct reduction iron briquetting machine, it is necessary to understand what the direct reduction iron is and the role of the briquetting.
