功能性无水炮泥采用原料均化和微粉预混技术,用特制复合原料作为外加剂,有良好的抗蚀性,填充性和烧结性等优良的性能,对铁口裂纹有强制修复功能,它能在铁口迅速产生一定的抗机械和化学损毁的能力,高温强度与残余炮泥结合性好,而出铁时又容易开口并保证铁水和熔渣快通过时冲蚀小,是铁水和熔渣的流动平稳,顺畅,从而抑制了炉内熔渣和铁水的环流,减轻了出铁口周围炉底侧的衬砖损蚀,很好的保护了高炉铁口区域的炉衬及炉缸,有益于延长高炉炉体寿命。
This product uses raw material homogenization and fine powder pre-mixing technology, and uses special composite raw materials as admixtures. It has good properties such as good corrosion resistance, filling properties and sinterability. It has a mandatory repair function for iron cracks. The mouth quickly produces a certain ability to resist mechanical and chemical damage. The high temperature strength is good in combination with the residual gun mud. It is easy to open when the iron is tapped and ensures that the molten iron and slag pass through quickly. It is the flow of molten iron and slag. Smooth and smooth, thereby suppressing the circulation of molten slag and molten iron in the furnace, reducing the corrosion of the lining bricks around the bottom of the furnace, and protecting the lining and hearth of the blast furnace iron mouth area, which is beneficial to extend the blast furnace Furnace life.
