Continuous feeding: the scrap steel is loaded into the conveyor or rail car with electromagnetic chucks, hydraulic grabs, and baskets, and is automatically and continuously added to the arc furnace from the upper part of the furnace shell on the side of the electrode no.1 and no.2 of the arc furnace. Afters that, the scrap will be continuously and automatically transported to the electric furnace.

Why can the certain brand of continuous feeding arc furnace achieve a daily production of 40-45 furnaces? This principle must be understood! A certain brand of continuous feeding EAF can realize continuous feeding, continuous preheating, continuous melting, continuous smelting and so on. And reduce the emission of smoke and dust.It is equipped with electromagnetic chucks, hydraulic grabs, and baskets from the scrap steel yard to the conveyor, and it is automatically and continuously added into the arc furnace from the upper part of the furnace shell on the side of the No.1and No.3 electrodes of the electric arc furnace(with track). And always maintain a certain amount of molten steel in the furnace.

The electric arc can directly heat the molten steel, and the molten steel can be directly melted through the molten steel, so that the operation is stable, the impact on the front-level power grid is small, the transformer capacity is reduced, and energy is saved. It is also called a 10-meter constant temperature system, and then enters the furnace when the temperature reaches 500-600. This system has nearly doubled the output. In the past, a furnace was produced in 50-60 minutes, but now it takes only 30 minutes.

The continuous feeding system fundamentally changes the tradition of unscrewing the furnace cover to add scrap steel to the furnace. There is no need to unscrew the furnace cover multiple times to avoid heat loss. The flue gas heat can partially preheat the scrap steel in the transport tank, which can save electricity and chemmistry. It can also improve the working environment and reduce the sencondary smoke and dust generated in the process of multiple feeding of the basket. The primary flue gas passes through the water cooling pipe and the sedimentation chamber and enters the bag to remove dust.

From a steel plant of electric furnace steelmaking site news, On 18^th, May, the electric furnace steel mill again reported a good news, breaking the historical records of daily production, daily production smelting and pouring double 38 furnaces, the average smelting cycle is 38.1 min, and the ourput is 3,705.174 tons. This is an electric furnace another milestone breakthrough after the continuous feeding technical reform of the plant, once again confirming the success of the continuous feeding tehnical reform of the electric furnace, marking the increasingly perfect and mature production mode of the “one pack of hot metal + continuous feeding + power supply” of the electric furnace steel plant. Entered the industry leading level of single-day furnace production and smelting cycle of the same type of electric furnace.

The electric arc furnace scrap steel continuous feeding device has the characteristics of continuous feeding, continuous preheating, continuous melting and continuous smelting. It has the advantages of short smelting cycle, low smelting energy consumption, low smelting noise and low investment cost. In the current steelmaking field, it is a world-leading technological equipment that reduces production costs, improves product quality, and improves market compeitiveness.
