一种含新型透气砖的精炼铸铁系统
摘要：
本发明公开了一种含新型透气砖的精炼铸铁系统，包括：炉壳、炉衬、炉壁层、底座、透气砂层、透气砖、透气砖支撑块、进气管、密封棉、云母片、螺母垫片，所述炉壳包裹着炉衬，所述炉衬外表面设置有炉壁层，所述炉壳的底部设置有底座，所述底座上方设置有透气砂层和透气砖，所述透气砂层与炉壁层相连，所述透气砖位于透气砂层和底座之间，所述透气砖下方设置有透气砖支撑块，所述透气砖支撑块位于透气砖和底座之间，所述进气管与底座和透气砖支撑块连接，所述密封棉包裹着进气管，所述云母片设置于螺母垫片和底座之间。本发明改进的透气砖具有优异的抗热震性和抗渣侵蚀性特点，同时较之于传统透气砖其力学性能及透气性也显著提高。
摘要（英）：

The invention discloses a refined cast iron system containing a novel ventilating brick. The system comprises a furnace shell, a furnace lining, a furnace wall layer, a pedestal, a permeable sand layer, the permeable brick, a permeable brick supporting block, a gas inlet tube, a sealing cotton, a mica sheet and a nut gasket, the furnace lining is wrapped with the furnace shell, the furnace wall layer is arranged on the outer surface of the furnace lining, the pedestal is arranged at the bottom of the furnace shell, the permeable sand layer and the permeable brick are arranged above the pedestal, the permeable sand layer is connected with the furnace wall layer, the permeable brick is located between the permeable sand layer and the pedestal, the permeable brick supporting block is arrangedbelow the permeable brick, the permeable brick supporting block is located between the permeable brick and the pedestal, the gas inlet tube is connected with the pedestal and the permeable brick supporting block, the gas inlet tube is wrapped with the sealing cotton, and the mica sheet is arranged between the nut gasket and the pedestal. The improved permeable brick has excellent thermal shock resistance and excellent slag corrosion resistance, and has significantly better mechanical properties and gas permeability than conventional permeable bricks.
