High-chromium sand ramming material for alkali furnace
A high-chromium sand ramming material for an alkali furnace is applied to a furnace lining of a melting tank of the alkali furnace of a paper mill, high-chromium particles or high-purity chromium particles and high-purity chromium powder are subjected to electric melting, then part of chromium ore sand and chromium ore powder are matched, and particle gradation optimization is conducted. By designing the microstructure of the material, the ramming material obtained by forcibly mixing the raw materials has high bulk density, the compactness of the finished product after ramming construction is improved, the construction performance of the ramming material is improved, and the furnace lining is high in strength, excellent in alkali liquor erosion resistance and long in service life.
一种碱炉用高铬砂捣打料，应用于造纸厂碱炉的熔化池炉衬，采用电熔高铬颗粒或高纯铬颗粒与高纯铬粉，再配以部分铬矿砂与铬矿粉，并进行颗粒级配优化，通过对材料微观结构进行设计，经过原料强制混合得到的该捣打料，堆积密度高，提高了捣打施工后成品的致密性，而且捣打料的施工性能得到了改善，炉衬不仅强度高，抗碱液侵蚀效果优良，使用周期长。
