目前,国内外炼铅厂家的铅鼓风炉炉缸砌体,一般是用镁砖或镁砖内衬同粘土砖的组合砌体砌成。但我厂铅鼓风炉炉缸却不用镁砖,而是用普通粘土耐火砖及高铝砖内衬的组合砌体砌成。长期的生产实践证实,铅鼓风炉炉缸采用高铝砖內衬,效果良好,较之镁砖砌体,在筑炉费用、使用寿命等方面均显示其优越性。 At present, lead blast furnace hearth masonry at home and abroad lead smelting factories are generally made of a combination of brick bricks or magnesia bricks lined with clay bricks. However, our factory lead blast furnace hearth but not magnesia brick, but ordinary clay refractory bricks and high alumina bricks lined with a combination of masonry. Long-term production practice has confirmed that the lead blast furnace hearth with high alumina brick lining, the effect is good, compared with the magnesia brickwork, in the furnace cost, the service life and so shows its superiority.
