Application of new technology in EAF steelmaking

Release date:2017-08-11 The author:www.xapyyj.com Click on:

In iron and steel production, the cost is the decisive factor, and the cost must be reduced to promote the development of electric furnace steel. Optimize the production process, strengthen the management and operation of the fine, from the optimization of burden structure, reduce the consumption of steel material, adding alloy concentrate and reducing agent, waste recycling to achieve direct alloying using steel slag and other aspects, in pursuit of the process cost and guarantee the lowest system cost.

In the optimization of burden structure, according to the change of steel demand and market price, ratio of iron scrap iron, fine collocation, each furnace of steel, and various types of steel scrap ratio and achieve the optimal charge structure. Iron and steel consumption is one of the largest proportion of electric furnace costs, reducing steel consumption is the key to reducing costs. By strengthening management and fine operation, it plays an important role in reducing the cost of electric steel.

The deficiency of direct reduction iron as scrap substitute to supplement scrap steel. With the development of industry technology, improve the user requirements of steel and electric steel varieties, the proportion increased, resulting in scrap supply is tight, especially in the production of high quality steel and clean steel required raw materials; and the control of scrap non-ferrous metal inclusions elements and harmful elements is the foundation of improving the quality of steel. Direct reduction iron does not contain these impurities and harmful elements are less in the electric furnace production can play with dilution of harmful elements and improve the effect of steel; arc furnace smelting with direct reducing iron, can form a melting period, the formation of carbon foam slag boiling, promote charge melting, reduce the lining of nitrogen, hydrogen content, protection of steel in the refining stage and shorten smelting time; direct reduction of iron composition is uniform and stable, a moderate, continuous feeding.

Adding alloy concentrate, direct reducing and alloying is beneficial to reduce the cost of alloy material, but by a variety of factors concentrate grade, recovery rate, harmful elements, slag and other constraints, the use of alloy concentrate in furnace is still not mature. As technology advances, the technology will have a profound impact on cost reduction.

The reasonable recovery and utilization of waste steel slag can make good use of metal and heat energy. At the same time, the Steel Corp of Anyang iron material in a variety of ways in the recovery of steel slag is still in production, will return to refining slag furnace, make full use of refining slag of high basicity slag and heat energy, and will further plan furnace slag for dephosphorization converter decarbonization.

Reducing production costs is a systematic work, including management and technical aspects. But with the management refinement and technological progress, it is believed that the cost of electric steel is still decreasing.

Repeated comparison of the new international leading direct reduction furnace short flow steelmaking equipment at home and abroad all kinds of direct reduction technology, the specific characteristics of the equipment are: ore powder and coal mixed in proportion into pellets. After drying after laying with continuous feeding and continuous preheating, continuous melting, continuous melting equipment, using coal powder (or gas) is heated to 1250 to 1350 DEG C, achieve rapid reduction of production of metallized pellets, discharged after direct hot charging of a high quality hot metal smelting furnace continuous addition. The efficiency of this method is high and the unit investment is low. This has become a leap in the metallurgical technology of iron and steel.
