一、高炉炉料结构的意义及国内外现状 合理的炉料结构是高炉获得良好技术经济指标的前提之一。七十年代以来,通过高炉解剖,日本炼铁界发现高炉软熔带并认识到软熔带的形状、位置特征与炉料结构以及原料冶金性能间的密切联系之后,炉料结构的问题在国外引起了高度重视。近年来,我国炼铁界也广泛关注到这一问题。 研究、选择炉料结构既须从高炉冶炼需要出发,却又不能脱离本国、本地区或企业的资源条件。基于这一原则,目前国外的高
First, the significance of blast furnace charge structure and the status quo at home and abroad reasonable charge structure is one of the prerequisites for obtaining good technical and economic indicators of the blast furnace. Since the 1970s, the problem of charge structure has been caused abroad by blast furnace anatomy, the founding of blast furnace refractories in Japan and the close correlation between the shape and location of the reflow ribbon and the charge structure and the metallurgical properties of the raw materials highly valued. In recent years, the ironmaking community in our country has also paid extensive attention to this issue. Research, choose the structure of the burden of both blast furnace smelting needs, but can not be divorced from the country, the region or business resource conditions. Based on this principle, the current foreign high
