The Development Of Electric Arc Furnace
The electric arc furnace is the most widely used steel furnace around the world, it can be used to smelt high-quality steel and other special steels.
Though the arc furnace came out in the 1900s, the major development waited its time till the end of WWII. During the latest decades, the development has escalated and brought revolutionary changes to the steel industry.
While the total output capacity remains growing slowly, the percentage of crude steel made from scraps has risen fiercely to 40% in 2001. One of the major solutions, an arc furnace can be built and operated at a lower cost than the traditional blast furnace.
Since the concept of the UHP arc furnace (ultrahigh power arc furnace) emerged in the mid-60s, people have tried to build bigger furnaces with higher power and capacity.
The application of advanced technologies like dynamic compensation systems and water-cooling systems boosts the development vigorously.
