The invention discloses a magnesium ramming mass for an electric furnace, belonging to the technical field of metal smelting. The magnesium ramming material is prepared from the following raw materials in percentage by mass: 12 to 17% of fused magnesia or high-purity magnesia, 25 to 35% of high-iron high-calcium sand with a particle size of less than or equal to 1 mm, 25 to 35% of high-iron high-calcium sand with a particle size of more than 1 mm and less than or equal to 3 mm and 22 to 27% of high-iron high-calcium sand with a particle size of more than 3 mm and less than or equal to 5 mm. According to the invention, only the high-iron high-calcium sand with different granularities and the high-purity magnesia or fused magnesia are matched for use, so the magnesium ramming mass has the characteristics of simple composition and convenience in use. Meanwhile, under the condition that other ingredients are omitted and only the two types of raw materials are adopted, the service life of an electric furnace is greatly prolonged, and an unexpected technical effect is achieved.
本发明公开了一种用于电炉的镁质捣打料，属于金属冶炼技术领域。该镁质捣打料由以下质量分数的原料组成：12%~17%的电熔镁砂或高纯镁砂、25%‑35%粒度<1mm的高铁高钙砂、25%‑35%的1mm<粒度≤3mm的高铁高钙砂、22%~27%的3 mm<粒度≤5mm的高铁高钙砂。本发明仅采用不同粒度的高铁高钙砂和高纯镁砂或电熔镁砂两种原料配合使用，具有组成简单，使用方便的特点。同时，本发明的捣打料在省略了其他配料的情况下，仅采用以上两种类型的原料，但却大大延长了电炉的炉龄，获得了预料不到的技术效果。
