| titleOfInvention | Method For Inhibiting Formation Of Cr+6 In the Waste Refrectory Materials Containing Chromium |
| abstract | The present invention relates to hexavalent chromium, which is an environmentally harmful substance during the disposal of chromium-containing refractory materials used as interior materials in various cement kilns, glass melting furnaces, steel calcination furnaces, and RH degassing plants. The present invention relates to a method of suppressing the occurrence of chromium-containing refractory materials, and to regenerate chromium-containing refractory materials at a predetermined temperature or more, and then rapidly cool them to suppress the generation of hexavalent chromium in the refractory materials. To minimize this, its purpose isn n n The present invention relates to a refractory material containing CaCO 3 and Cr 2 O 3 , which is used in at least a part of a facility in which a process for maintaining CaCrO 4 is maintained above a temperature at which it is produced and is discarded when the service life is reached, wherein the temperature of the refractory material Obtaining a stable phase region of CaCrO 4 and CaCr 2 O 4 according to the present invention; And before disposing of the refractory material, reheating to a temperature higher than the temperature of CaCrO 4 in the stable phase so that Cr is present as CaCr 2 O 4 , and then maintaining a stable temperature range without CaCr 2 O 4 transformation and Cr 2 O 3 . The method for inhibiting the hexavalent chromium generation of the chromium-containing waste refractories comprising the step of rapid cooling to maintain until the main point. |
