Method for the introduction of inorganic solid bodies into hot liquid melts

Abstract

A method is disclosed for the introduction of inorganic solid bodies into hot, liquid melts, whereby inorganic solid bodies are added to a plastic containing a hydrocarbon and the mixture obtained is added to the hot, liquid melt.

1 - 15 . (canceled)  
   
   
       16 . A process comprising adding inorganic solids to a hydrocarbon-containing plastic and introducing the resulting mixture into a liquid melt.  
   
   
       17 . A process according to  claim 16 , wherein 90% of the inorganic solid particles have sizes of 0.01 μm to 5 mm.  
   
   
       18 . A process according to  claim 17 , wherein 90% of the inorganic solid particles have sizes of 0.1 μm to 2 mm.  
   
   
       19 . A process according to  claim 16 , wherein the proportion of inorganic solids in the plastic is 0.5 to 90 wt. %.  
   
   
       20 . A process according to  claim 19 , wherein the proportion of inorganic solids in the plastic is 2 to 70 wt. %.  
   
   
       21 . A process according to  claim 16 , wherein the inorganic solids are at least one solid selected from the group consisting of a titanium-containing substance, iron oxide, aluminum oxide, magnesium oxide, calcium oxide, a silicate, and a slag-forming additive.  
   
   
       22 . A process according to  claim 21 , wherein the flux contains synthetic titanium dioxide.  
   
   
       23 . A process according to  claim 16 , wherein the plastic comprises nitrogen.  
   
   
       24 . A process according to  claim 16 , wherein the plastic used is old plastic.  
   
   
       25 . A process according to  claim 16 , wherein the plastic is mixed in solid form with the inorganic solids.  
   
   
       26 . A process according to  claim 16 , wherein the plastic is mixed in molten form with the inorganic solids.  
   
   
       27 . A process according to  claim 26 , further comprising cooling the mixture until the mixture solidifies to form a solidified plastic/flux mixture.  
   
   
       28 . A process according to  claim 27 , wherein the solidified plastic/flux mixture is ground or shredded.  
   
   
       29 . A process according to  claim 16 , wherein the plastic/flux mixture is introduced into the hot liquid melts by injection.  
   
   
       30 . A process according to  claim 16 , wherein the plastic/flux mixture is introduced into the hot liquid melts in the form of lumps.
