Grinding device

Abstract

A device for grinding a continuously cast product, in particular a slab (11), a billet or a block. The Device has at least one rotationally operated abrasive disk (10), which is attached to a grinding head (15). At least one high-pressure air nozzle (14) is arranged on the grinding head (15). The high-pressure air nozzle blows the continuously cast product free of particles adhering to or lying on the continuously cast product prior to grinding.

1 . A device for grinding a continuously cast product, the device comprising:
 a grinding head;   at least one grinding wheel configured to be rotatingly operated the at least one grinding wheel being fastened to the grinding head; and   at least one high-pressure air nozzle, which clears particles adhering to or lying on the surface of the continuously cast product before a grinding operation, the at least one high-pressure air nozzle being arranged on the grinding head.   
     
     
         2 . A device in accordance with  claim 1 , further comprising another high-pressure air nozzle to provide at least two high-pressure air nozzles with the high-pressure air nozzles arranged on the grinding head on both sides of the grinding wheel or in the grinding wheel, so that at least one of the high-pressure air nozzles, which blows away particles before the grinding operation, can be operated in case of a change in grinding direction. 
     
     
         3 . A device in accordance with  claim 1 , wherein the nozzle is arranged in relation to the grinding wheel such that the nozzle both blows away particles before the grinding operation and is used for the immediate blowing away of developing grinding dust. 
     
     
         4 . A device in accordance with  claim 1 , wherein the high-pressure air nozzle generates an air pressure of at least 2×10 5  Pa. 
     
     
         5 . A device in accordance with  claim 1 , wherein the high-pressure air nozzle is configured as a flat blast nozzle and/or is configured for discharging air with an air outlet velocity of at least 100 m/sec. 
     
     
         6 . A device in accordance with  claim 2 , wherein the nozzle is arranged in relation to the grinding wheel such that the nozzle both blows away particles before the grinding operation and blows away grinding dust developing during the grinding operation. 
     
     
         7 . A device in accordance with  claim 2 , wherein the high-pressure air nozzle generates an air pressure of at least 2×10 5  Pa. 
     
     
         8 . A device in accordance with  claim 3 , wherein the high-pressure air nozzle generates an air pressure of at least 2×10 5  Pa. 
     
     
         9 . A device in accordance with  claim 1 , wherein the high-pressure air nozzle generates an air pressure of from 5×10 5  Pa to 12×10 6  Pa. 
     
     
         10 . A device in accordance with  claim 2 , wherein the high-pressure air nozzle generates an air pressure of from 5×10 5  Pa to 12×10 6  Pa. 
     
     
         11 . A device in accordance with  claim 3 , wherein the high-pressure air nozzle generates an air pressure of from 5×10 5  Pa to 12×10 6  Pa. 
     
     
         12 . A device in accordance with  claim 2 , wherein the high-pressure air nozzle is configured as a flat blast nozzle and/or is configured for discharging air with an air outlet velocity of at least 100 m/sec. 
     
     
         13 . A device in accordance with  claim 3 , wherein the high-pressure air nozzle is configured as a flat blast nozzle and/or is configured for discharging air with an air outlet velocity of at least 100 m/sec. 
     
     
         14 . A device in accordance with  claim 4 , wherein the high-pressure air nozzle is configured as a flat blast nozzle and/or is configured for discharging air with an air outlet velocity of at least 100 m/sec. 
     
     
         15 . A device in accordance with  claim 1 , wherein the high-pressure air nozzle is configured as a flat blast nozzle and/or is configured for discharging air with an air outlet velocity of at least 200 m/sec. 
     
     
         16 . A device in accordance with  claim 2 , wherein the high-pressure air nozzle is configured as a flat blast nozzle and/or is configured for discharging air with an air outlet velocity of at least 200 m/sec. 
     
     
         17 . A device in accordance with  claim 3 , wherein the high-pressure air nozzle is configured as a flat blast nozzle and/or is configured for discharging air with an air outlet velocity of at least 200 m/sec. 
     
     
         18 . A device in accordance with  claim 4 , wherein the high-pressure air nozzle is configured as a flat blast nozzle and/or is configured for discharging air with an air outlet velocity of at least 200 m/sec.
