Electric Furnace Steel

Electric furnace steel is steel produced in a steelmaking furnace powered by electricity. There are many types of electric furnaces, including electric arc furnaces, induction electric furnaces, electro-slag furnaces, electron beam furnaces, and consumable electric arc furnaces. But the so-called electric furnace steel is the steel produced by a basic electric arc furnace.

There are various types of electric furnace steel, mostly high-quality carbon structural steel, tool steel, and alloy steel. The electric furnace steel has excellent quality and uniform properties. When the carbon content is the same, the strength and plasticity are better than open hearth steel.


Electric furnace steelmaking has the advantages of less pollution, high thermal efficiency, and high smelting quality. But it also has the disadvantages of large power consumption and high production cost.

Electric furnace steel production is one of the main production processes of modern steel. Compared with converter steelmaking, it has the advantages of low investment, short construction period, quick results and short production process, flexible production scheduling, a high proportion of high-quality special steel smelting, especially alloy steel, high alloy steel, and other high value-added, high strength, The smelting of high-performance special steel varieties such as high toughness now basically relies on electric furnaces.

The modern electric furnace process is: electric furnace smelting, secondary refining, continuous casting, (hot delivery and hot charging), and rolling. Electricity and steel scrap are two necessary conditions for EAF steel production. 55% of the cost of electric furnace steel in special steel enterprises comes from scrap steel. The power consumption cost of special steel enterprises accounts for 15% of the total cost.


Steel is classified according to smelting equipment, which can be divided into converter steel, open hearth furnace steel, and electric furnace steel.

According to different electric heating methods and steelmaking furnace types, electric furnace steel can be divided into electric arc furnace steel, non-vacuum induction furnace steel, vacuum induction furnace steel, electro slag furnace steel, vacuum electric arc furnace steel (also known as vacuum consumable furnace steel), Electron beam furnace steel, etc.

Electric arc furnace steel

Electric arc furnace steel refers to the electric energy input into the furnace through the graphite electrode in the electric arc furnace, and the arc generated between the electrode end and the charge (scrap steel, etc.) is used as the heat source to melt and refine the charge and alloy material. The main varieties of electric arc furnace steel are high-quality carbon steel, low alloy steel, and alloy steel. The electric arc furnace steelmaking method is the main steelmaking method for producing high-quality steel and special-quality steel.


Non-vacuum electric induction furnace steel

Non-vacuum electric induction furnace steel refers to the steel made by melting and refining scrap steel, alloy materials, and other furnace materials by using induction electrothermal effect in a non-vacuum induction furnace. The main variety is special quality alloy steel.


Vacuum electric induction furnace steel

Vacuum electric induction furnace steel refers to the steel that is melted and refined by using induction electrothermal effect to melt and refine furnace materials such as scrap steel and alloy materials in a vacuum induction furnace. Vacuum induction furnace steel has low gas content, low content of sulfur and phosphorus impurity elements, and few inclusions. The main varieties are special quality alloy steels for special purposes.


Electroslag furnace steel

Electroslag furnace steel refers to the refining process in which the steel initially smelted in an open hearth furnace, converter, electric arc furnace, or induction furnace is cast or forged into electrodes in the electro-slag furnace, and then remelted twice through the slag resistance in the electro slag furnace. Forged steel. Electroslag furnace steel has low sulfur content, fewer impurity elements, and fewer inclusions. The main species of electro-slag furnace steel is special quality alloy steel.

Troubleshooting of Medium Frequency Furnace

Troubleshooting of Medium Frequency Furnace This article introduces the faults and solutions of medium frequency furnace. 1. Fault phenomenon: large DC current, low DC voltage, and if the voltage, dull equipment sound, over-current protection. Analysis and treatment: the thyristor with one arm of the inverter bridge may be short-circuited or open-circuited, resulting in the operation of the three-arm inverter bridge. Use an oscilloscope to observe the voltage drop waveform of the thyristor on the four bridge arms of the inverter bridge. If the voltage drop waveform of the thyristor on one bridge arm is a line, the thyristor has been through; if it is a sine wave, the thyristor has not been through. Replace the through thyristor; find out the reason why the thyristor is not turned on. 2. Fault phenomenon: when the heavy load cold furnace is started, all electrical parameters and sounds are normal, but the power cannot be raised, and overcurrent protection. Analysis and

Advantages and Disadvantages of Electric Arc Furnace and Induction Furnace Steelmaking

Electric Arc Furnace VS Induction Furnace Steelmaking Comparison of advantages and disadvantages of electric arc furnace and induction  furnace steelmaking 1. The induction furnace heats up quickly and has high thermal efficiency. The heat is generated inside the charge (steel liquid), so the heating is fast. In the arc furnace, the heat of the arc after the material is cleared must be transferred to the molten steel through the slag, which is indirect heating. Thermal efficiency is poor. The furnace is in the shape of a basin, and a large part of the heat of the arc is lost through the furnace cover and the furnace wall. 2. The oxidative burning loss of elements in induction furnace steelmaking is less. Because there is no ultra-high temperature action of the arc in the induction furnace steelmaking, the burning rate of the elements in the steel is low. 3. In the induction furnace steelmaking, the composition and temperature of the molten steel are relatively uniform.
