Product Introduction

现代热风炉技术应用日趋成熟,平均风温高达1250~1300℃。所以对炉内耐火材料要求就更加苛刻,尤其是其高温区域如蓄热室上部、燃烧室等更容易受到损坏,直接影响到热风炉的使用效果及寿命。为此,有关客户及专家已提出了热风炉的使用寿命为两代高炉寿命的目标。所以,对热风炉高温区域用耐材提出了更严峻的挑战。选择一种高温热稳定性好,抗高温压缩蠕变能力强,荷重软化温度高,性价比合理的耐材应用于高风温热风炉已成耐材行业的一项重要任务,而性能优良的硅砖正具有上述特点。

我公司生产的低蠕变、高荷软、低残余石英含量的热风炉用优质硅砖采用自有矿山(洛阳市铁门镇)盛产的结晶硅石为原料,为已成功应用于国内外各大钢铁企业的各种类型的热风炉。
