| titleOfInvention | Magnetite brick production |
| abstract | The present invention relates to a method for producing a composition of heat storage magnetite brick used in a heat storage electric hot air heater, a heat storage electric boiler, and more specifically, a brick with a iron oxide content (Fe 2 O 3 ) of 90% or more by using hematite, magnetite and iron shell. It relates to a regenerative magnetite brick production method used in regenerative electric hot air blower as a molding method.n n n To this end, the present invention, the step of heat-treating the iron bar as a by-product during steel production in the steel mill at 300 ℃ ~ 450 ℃ 12 hours or more; Heat-treating hematite powder and magnetite powder raw material at 250 ° C. to 300 ° C. for 10 hours; Mixing the prepared raw material with clay and sodium silicon; Shaping the mixed raw materials; Drying the molded product in a drying zone of 50 ° C. to 80 ° C .; It is characterized by consisting of firing the dried product in an electric furnace of 250 ℃ ~ 400 ℃.n n n This has all the characteristics of recycling the raw materials and the iron oxide content and the refractory, and has an excellent effect that can be produced at low temperatures. |
