Abstract:
PCT No. PCT/EP90/00335 Sec. 371 Date Oct. 25, 1990 Sec. 102(e) Date Oct. 25, 1990 PCT Filed Feb. 28, 1990 PCT Pub. No. WO90/10086 PCT Pub. Date Sep. 7, 1990.This invention is directed to a smelting plant with shaft-like charging material preheater. In a smelting plant with an electric arc furnace (1) and a charging material preheater (2) of shaft configuration arranged laterally on the furnace, the outer walls of the charging material preheater in the lower region thereof are formed by the vessel wall (5) of the furnace while in the region thereabove they are formed by the walls of a shaft which is fixed in a holding structure (27). By a horizontal relative movement between the furnace vessel (3) and the holding structure (27) together with the vessel cover (6), without being impeded by the shaft (10) charging material can be charged from a scrap basket directly into the furnace vessel or through the displaced shaft into different regions of the furnace vessel (3). Charging material can be retained in the shaft by means of a blocking member (51) therein, and heated up during the refining phase.
