A delivery chute for delivering sinter material onto a sinter cooler and a method for delivering sinter material from a sinter belt onto a sinter cooler are provided. The sinter material introduced into the delivery chute may be divided by distributor plates into at least two sinter material subflows flowing in different directions, which may be guided into the edge regions of a sinter material total flow obtained by combining them.

Scrap-melting electric arc furnace

In a method for manufacturing a base anode (10) having a multiplicity of adjacently arranged metal elements (11) for a metallurgical vessel (1), the intermediate spaces (14) between the metal elements (11) are filled with refractory material (16), the refractory material (16) being compressed. To achieve a high degree of compression in a short period of time, the compression of the refractory material (16) takes place by means of vibration.

Method for manufacturing a base anode for a metallurgical vessel

There is disclosed a plant for treating and melting metals, metal compounds and/or metal alloys or for producing calcium carbide. It includes a burden-receiving shaft and a melting furnace arranged below the shaft and including a heating means. A passage opening is provided between the shaft and the melting furnace, which passage opening serves to introduce the burden present within the shaft into the melting furnace.

Plant for treating and melting metals, metal compounds and/or metal

A plant for metallurgical treatments, in particular for melting or melt-reducing metals, metal compounds and/or metal alloys, or for producing calcium carbide, comprises a shaft receiving a burden, a melt collecting space disposed laterally of, and below, the shaft, as well as at least one burner arranged laterally of the shaft. In order to enable the accurate process control of the metal melt and the controlled smelting of the burden, the burner is arranged in a combustion space connecting the lower shaft end with the melt collecting space and designed as a plasma burner. The combustion space is located at a level above the melt collecting space and including a combustion space bottom, which is plane, or preferably rises, relative to the shaft and enters into the melt collecting space by an overflow edge that separates the metal melt from the burden.

Plant to be used for metallurgical treatments of metal compounds and/or

In order to melt particulate material in an electric furnace with the help of at least one electric arc burning between a burner electrode arranged in the lid of the furnace and a bottom electrode arranged in the bottom of the furnace, the material is introduced into a space surrounding the electric arc. It is melted by the radiation heat of the electric arc and is collected in a melt bath covering the bottom part of the furnace. In order to attain a high energy exploitation and to prevent the material to be melted from being extracted, a fixed bed of the material to be melted is formed in the space surrounding the electric arc, which takes its root on the bottom part of the furnace and peripherally surrounds the electric arc. The material is melted on the side of the fixed bed facing the electric arc. The fixed bed is moved approximately radially towards the center of the furnace to an extent corresponding to the melted material volume. The material to be melted is charged between the fixed bed and a shell externally surrounding the fixed bed.
