自焙炭块除具有传统的焙烧炭块所具有的耐高温、高温强度大、不易粘渣铁、耐侵蚀等特性外,能够利用烘炉和高炉生产过程的热量逐步培烧成坚实、致密近于无缝的整体炉衬。第六、七代自焙炭块主要技术指标己优于国产传统的焙烧炭块,多数性能指标已达到或接近国际上80年代大型高炉用炭块的质量水平。自焙炭块及自焙炭块炉衬技术是中、小高炉经济可行、安全可靠的长寿炉衬技术。在此基础上研究、开发的半石墨化自焙炭块—陶瓷砌体复合炉衬技术在鞍钢7号(2580m~3)、4号(1002m~3)和太钢3号(1200m~3)高炉中应用已初见成效。
In addition to the traditional roasting carbon block has high temperature resistance, high temperature strength, easy to stick slag iron, corrosion resistance and other characteristics, can use the oven and blast furnace heat of the process of gradually bake into a solid, dense Seamless overall lining. Sixth, seven generations of self-baking carbon block has better than the main technical indicators of the traditional roasted carbon block, the majority of performance indicators have reached or approached the international large-scale blast furnace with carbon blocks in the 1980s the quality level. Self-baking charcoal block and baking carbon block lining technology is medium and small blast furnace economically viable, safe and reliable longevity lining technology. On this basis, the technology of semi-graphitized self-baking carbon block-ceramic masonry composite lining researched and developed in Anshan Iron and Steel Company (Anshan Iron and Steel Group Co., Ltd.) at Anshan Iron and Steel Company No. 7 (2580m ~ 3), No. 4 (1002m ~ 3) Application has shown initial success.
