摘要： An iron production furnace equipment (1) has a melting reactor (2) into which iron oxide-containing raw material (4) and slag formers (5) are added. A melter arrangement (22) melts the iron oxide-containing raw material and transforms the melted raw material into liquid slag (6) A smelting reduction reactor (3) is connected to the melting reactor by a slag transfer arrangement (10). The smelting reduction reactor comprises a heater arrangement (30) for heating the slag. Means (32) for supplying a reductant (7) for reducing the iron oxide in the slag into a liquid iron melt (8) and for producing a combustible gas mixture (11) comprising at least one of CO and H
2 . A gas connection (12) is connected between the smelting reduction reactor and the melter arrangement. The melter arrangement in turn comprises a combuster (28) combusting the gas mixture. The combustion heat is used for purpose of melting.

摘要： The present invention relates to a method for melting steel in an electric arc furnace (EAF). A hot heal (15) is provided in the EAF. Metal scrap (16) is loaded into the EAF. The metal scrap(16)is melted in the EAF. According to the invention the mass of the hot heel (15) in relation to the mass of the metal scrap that is initially beyond the surface of the hot heel is a certain minimum. This minimum is 0,75 times the relation between the heat required to melt the metal scrap beyond the surface of the hot heel (15) and the het that can be taken from the hot heel without it being solidified when a theoretical heat balance calculation is applied as defined in a formula.

摘要： The apparatus includes a furnace having a furnace chamber (14), a port (16) in fluid communication with the furnace chamber having an inclined lower wall (18), and a bi-directional induction unit (24) mounted to the inclined lower wall for inducing flow in molten material in the port. A retractable channel plate assembly (26) is selectively positionable in the port to define an extraction flow channel (28) for the molten material between the channel plate assembly and the inclined lower wall. A drive arrangement (64) moves the channel plate assembly into and out of the port and the control of a control system (74) which includes a sensor system (78) for measuring the level of the molten material in the port and a feedback system for providing information regarding the position of the channel plate assembly. A method of operating the apparatus is also disclosed.
