摘要:
The invention relates to a metallurgical vessel (1), in particular an arc furnace, having a holding container (2) for metal melt and having a lid (3), by means of which the holding container (2) can be at least partially covered, wherein the metallurgical vessel also has at least one lance (4, 5) for the supply of a medium into the metallurgical vessel (1), and wherein the at least one lance (4, 5) is pivotably arranged on or in the metallurgical vessel (1). In order to be able to introduce a medium into the interior of the furnace in an improved manner, the invention provides that at least one lance (4, 5) is arranged in the region of the lid (3) of the metallurgical vessel (1) on a revolute joint (6) which has a rotational axis aligned in a horizontal direction (H).

The invention relates to a device for detecting the temperature and for analyzing molten masses in metallurgical vessels. Said device comprises a channel pipe (KN) for receiving a sample of a molten mass, which is provided on the lateral wall of the metallurgical vessel (KV), runs with its lower end into the wall thereof and terminates with its upper open end above the metallurgical vessel (KV). Said channel pipe is provided upstream of the inlet with an air inlet with an associated intake and discharge valve (VT) and above said air inlet with a rotary valve (DS) that opens the cross-section of the channel pipe (KR), allowing to introduce measuring probes, lasers or temperature sensors, and closes it.

摘要:
The invention relates to a method and device for producing liquid steel (1), wherein the inventive method consists in melting metal materials (2) in an independent melting vessel (3) by means of fossil energy sources (4), in processing a molten material (5) in an overheating vessel (6), in tapping said molten material and transporting it to another treating vessel (7) and in analysing the steel quality. The inventive method makes it possible to economically consume energy and involves the following stages: preheating/melting, overheating, transport and a secondary metallurgical/overheating processing.
