摘要： A scrap steel preheating type electric arc furnace and a method for improving a heating cold region of a side wall charging electric arc furnace are provided. The scrap steel preheating type electric arc furnace includes an electric arc furnace body and an inclined scrap steel preheating chamber. An included angle between the scrap steel preheating chamber and a horizontal plane is 30° to 65°. The scrap steel preheating chamber is connected with the electric arc furnace body. A dust removal pipe chamber is at an upper end. A material blocking tooth rake is on the scrap steel preheating chamber. A driving mechanism is below the material blocking tooth rake. Flue gas enters the scrap steel preheating chamber, penetrates through the material blocking tooth rake and the scrap steel and is sucked out by the dust removal pipe chamber. The scrap steel is preheated; then, the material blocking tooth rake is opened; and the preheated scrap steel slides to a center of the electric arc furnace body along a slot bottom of the inclined scrap steel preheating chamber. A falling angle of the scrap steel is changed through a method of matching the scrap steel preheating chamber with a large inclined angle and the material blocking tooth rake, thereby overcoming a problem of lateral stacking of the side wall charging electric arc furnace, reducing impact force of the scrap steel to the device and greatly enhancing reliability of the device.

摘要： A steelmaking plant method and apparatus which includes a pressurized direct reduction reactor for continuous production of hot direct reduced iron (ORI); feeding such DRI to a batch melting furnace or to a standby cooler. The furnace is selectively charged through a diverter valve by a pneumatic transport system with the hot DRI being entrained in a motive carrier gas fed via a first conduit into a receiving bin. A pressurized charge of the DRI accumulated in such disengaging buffer bin is periodically fed via a second conduit down into low dosing/depressurization bin which in turn depressurizes the DRI and feeds a batch of DRI down into the furnace. Upon sensing the capacity of the buffer portion of the receiving bin being filled, the DRI! is then pneumatically diverted from the reactor to the cooler, such as during shut down of the furnace for maintenance or otherwise.

摘要： At the production of the secondary steel based on scrap, wherein the scrap (10) is fed in a scrap preheater (2) through a charging device (1), is preheated there and, finally, is brought into a smelting unit (3) and is melted there with primary energy only, the process gases (19), which leave the smelting unit (3), are not used any more for directly preheating the scrap (10) but are rather used indirectly by heating a gaseous preheatable medium, e.g., air (18) or inert gas, whereby energetic, fluidic, and spatial decoupling of preheating and melting and of post-combustion and preheating is achieved.
