Metallurgical complex

Abstract

The invention relates to metallurgy and, more specifically, to iron-and-steel producing plants. The metallurgical complex is provided with three production platforms arranged one above the other. The middle platform is capable of rotating about a central axis and is provided with three identical lined containers situated in three positions at an angle of 120° to each other. The top platform is provided with means for melting metal and means for processing the melt capable of rising and lowering and installed on two adjacent lined containers to form steelmaking arc furnace positions and a melt processing unit position, respectively. The casting station is mounted on the bottom platform in the immediate vicinity of the lined container disposed in the third position. The invention provides high-level automation in the production of molten steel and cast blanks

1 . A metallurgical complex comprising:
 a melting furnace,   an out-of-furnace metal processing unit and   a casting station installed on technological platforms capable of receiving and transferring molten metal with subsequent casting,   wherein the metallurgical complex is provided with three technological platforms installed one over another, the middle platform being capable of rotating about the central axis, and is also provided with three identical lined containers situated in three positions at an angle of 120° to each other, the top platform being provided with a metal melting device and melt processing device capable of rising and lowering and installed on two adjacent lined containers to form steelmaking arc furnace positions and melt processing unit positions, respectively, the casting station being mounted on the lower platform in the immediate vicinity of the third position with a third lined container disposed therein.   
     
     
         2 . The metallurgical complex as claimed in  claim 1 , wherein the lined containers are made with a possibility of their inclination. 
     
     
         3 . The metallurgical complex as claimed in  claim 1 , wherein the metallurgical complex is provided with a device for preheating the fusion mixture capable of being installed on a lined container disposed in the third position. 
     
     
         4 . The metallurgical complex as claimed in  claim 3 , wherein the device for preheating the fusion mixture is a gas burner. 
     
     
         5 . The metallurgical complex as claimed in  claim 4 , wherein the gas burner is fixed on a cover to be installed on a lined container disposed in the third position. 
     
     
         6 . The metallurgical complex as claimed in  claim 1  wherein the middle platform is installed on a roller support station connected to a rotary drive. 
     
     
         7 . The metallurgical complex as claimed in  claim 1 , wherein the metallurgical complex is provided with a matching device to control the rotation of the middle platform and movement of the metal melting device and melt processing device. 
     
     
         8 . The metallurgical complex as claimed in  claim 1  wherein the middle platform is made in the form of a ring. 
     
     
         9 . The metallurgical complex as claimed in  claim 1 , wherein the metal melting device and melt processing device are made in the form of an electrode system and a lined dome.
