Metallurgy ladle about the advantages and disadvantages

Metallurgy ladle have some advantages and  disadvantages

Pouring ladle  of the advantages

Waste alloying elements can be recycled, refractory alloying elements can be melted by arc at high temperature, and the temperature in the furnace can be precisely controlled.  To sum up, eAF uses scrap steel as the main raw material, so alloy elements in scrap steel can be reused in EAF steelmaking.  The electric arc furnace uses the heat generated by the arc between graphite electrode and iron material to smelting iron material, the arc temperature is above 3000, so that the electric arc furnace smelting refractory alloy elements;  At the same time, by accurately adjusting the current to control the temperature in the furnace, the electric arc furnace can accurately control the temperature of molten steel for a long time;  The electric arc furnace process is flexible and can meet the requirements of smelting small batch/many varieties of special steel.  

Flat bottom ladle of the disadvantages

Scrap steel has great influence on the quality of molten steel, long smelting cycle and large power consumption.  To sum up, electric arc furnace uses scrap steel as the main raw material. More impurities may be introduced into molten steel during smelting, resulting in low quality molten steel.  According to our published on June 25, 2017, the carbon industry one of the special report: new electric furnace steel with carbon (I) on the drive graphite electrode demand, technological progress, the concentration of ascension to long-term development, the depth of the report, the current widespread use of the fourth generation of electric furnace tapping is 55 ~ 60 minutes on average, tap-to-tap time is longer than the converter steelmaking;  The power consumption is 500 KWH/ton, causing great pressure on the local power grid.
