Method for strip casting steel and system for strip casting

Abstract

The invention relates to a method for casting steel having a chromium content of more than 15 wt.-%, which is characterized in that the steel is cast in a horizontal strip casting system ( 1 ) comprising a melting furnace ( 2 ), foundry ladle ( 3 ) and conveyor belt ( 5 ) for receiving and for cooling a liquid steel strip flowing from the foundry ladle ( 3 ).

1 - 8 . (canceled) 
     
     
         9 . A method of casting a steel with a chromium content of more than 15 percent by weight, comprising the steps of casting the steel in a horizontal strip casting device. 
     
     
         10 . The method according to  claim 9 , wherein the chromium content is more than 33 percent by weight. 
     
     
         11 . The method according to  claim 9 , including casting the steel with a carbon content of more than 1 percent by weight. 
     
     
         12 . The method according to  claim 9 , including casting the steel with a silicon content of more than 2 percent by weight. 
     
     
         13 . The method according to  claim 9 , including casting the steel as strip or plates, the method further including cutting, milling, boring or annealing the cast strip or plates. 
     
     
         14 . A horizontal strip casting device for casting steel with a chromium content of more than 15 percent by weight, the device comprising: a melting furnace; a casting ladle; and a transport band for receiving and cooling liquid steel flowing out of the casting ladle. 
     
     
         15 . The strip casting device according to  claim 14 , wherein the transport band has indentations for forming cast plates within the steel strip or transversely extending projections for forming intended breaking points within the steel strip. 
     
     
         16 . The strip casting device according to  claim 15 , further comprising chip-removing devices that predetermine a width and a length of the cast plates. 
     
     
         17 . The strip casting device according to  claim 14 , further comprising a severing or cutting device for cutting steel strip, the severing or cutting device being arranged following the transport band in a conveying direction of the steel strip.
