Device For Producing A Hot-Rolled Thermal Strip, Especially Made Of Strip-Type Continuous Casting Material

Abstract

The invention relates to a device for the production of hot-rolled steel strip comprising at least one continuous casting machine, at least one pair of scissors, at least one calibration oven, a de-scaler, optionally, a roughing train, a finishing train (multi-stand rolling mill or Steckel mill(s)), a roller path comprising a cooling area and at least one pickup reel for the thermal strip. A compact structure is achieved by virtue of the fact that the casting line and the rolling line are arranged parallel or approximately parallel to each other such that the direction of casting and direction of rolling are oriented essentially in an opposite direction to each other.

1 . Arrangement for producing hot-rolled steel strip, which comprises at least one continuous casting machine, at least one shear, at least one soaking furnace, a descaler, possibly a roughing train, a finishing train (multi-stand rolling mill or Steckel mill(s)), a roller table with a cooling zone, and at least one coiling reel for the hot strip, characterized by the fact that the casting line and the pass line are arranged parallel or approximately parallel to each other in such a way that the casting direction and the rolling direction are oriented essentially opposite each other.  
     
     
         2 . Arrangement in accordance with  claim 1 , characterized by the fact that the casting line and the pass line are connected with each other by a reheating furnace.  
     
     
         3 . Arrangement in accordance with  claim 1  or  claim 2 , characterized by the fact that the distance between the casting line and the pass line is designed in such a way that a sufficient residence and buffering time for the thin slabs in the reheating furnace is guaranteed.  
     
     
         4 . Arrangement in accordance with  claim 1 ,  claim 2 , or  claim 3 , characterized by the fact that the reheating furnace is designed to hold at least three slabs and a maximum of twelve slabs.  
     
     
         5 . Arrangement in accordance with one or more of  claims 1  to  4 , characterized by the fact that the reheating furnace is a stepped rocker-bar hearth furnace.  
     
     
         6 . Arrangement in accordance with one or more of the preceding claims, characterized by the fact that the reheating furnace is a roller hearth furnace, a hot box, a walking-beam furnace or a combination of these suitable furnace types or of other furnaces of these types.  
     
     
         7 . Arrangement in accordance with one or more of the preceding claims, characterized by the fact that the casting line consists of one or more casting machines or several cast strands.  
     
     
         8 . Arrangement in accordance with one or more of the preceding claims, characterized by the fact that the casting and rolling plane are preferably arranged at the same height.  
     
     
         9 . Arrangement in accordance with one or more of the preceding claims, characterized by the fact that the casting plane and rolling plane are vertically displaced relative to each other.  
     
     
         10 . Arrangement in accordance with one or more of the preceding claims, characterized by the fact that at least one continuous furnace is arranged between the casting machine and the reheating furnace.  
     
     
         11 . Arrangement in accordance with one or more of the preceding claims, characterized by the fact that at least one continuous furnace is arranged between the rolling mill and the reheating furnace.  
     
     
         12 . Arrangement in accordance with one or more of the preceding claims, characterized by the fact that the casting machine with the downstream continuous furnace and the rolling mill with the upstream continuous furnace can be connected by a parallel or swivel ferry.  
     
     
         13 . Arrangement for producing hot-rolled steel strip, with at least one continuous casting machine, at least one shear, at least one soaking furnace, possibly a roughing train, a finishing train, a roller table with a cooling zone, and a coiling reel, especially in accordance with any of  claims 6  to  12 , characterized by the fact that the casting line and the pass line are arranged at an angle relative to each other of >0° up to about 150°.  
     
     
         14 . Arrangement in accordance with  claim 13 , characterized by the fact that the casting line and the pass line are connected with each other by a swivel ferry.
