Development of EAF Steelmaking
The development of EAF steelmaking can be divided into three stages。From the beginning of small EAF specialized in smelting alloy steel, to the later change to large EAF for smelting alloy steel and plain carbon steel, until the recent ultra-high power large (AC, DC) EAF only used as scrap melting equipment.

What Is an Electric Arc Furnace?
An electric arc furnace, also known as an electric arc furnace (EAF), is a device that uses an electric arc to heat materials that are usually metals to the melting point. A typical electric arc furnace melts a material by passing an electric current through a set of electrodes, or "charge".

What Types of Rolls Are Used in Rolling Mills?
There are many different specifications and materials for rolling mill rolls, such as forged rolls and centrifugal casting rolls. Casting rolls are divided into high, medium and low nickel. Because the classification and use of rolls are complicated, we mainly analyze the quality indicators of different rolls used in rolling mills.

Classification of Continuous Steel Leakage Accidents and Analysis of Some Causes
The so-called steel leakage refers to the phenomenon that the solidification of the billet shell is not good or the billet shell is broken or leaked due to the action of other external forces, causing the internal molten steel to flow out during the continuous casting or the casting process. Steel leakage is one of the vicious accidents in continuous casting production. Serious steel leakage accid...

Can Rolling Mill Lubricant Reduce Rolling Force and Power Consumption?
The working rollers and bearing roller bearings of rolling mills are generally lubricated with dry oil, and oil film bearings and oil mist, oil gas are used to lubricate at high speeds. The gearboxes of rolling mills, motor bearings, and reducers in electric pressure devices use thin oil circulation lubrication.
