一种转炉用镁质护炉料
摘要：
本发明公开了一种转炉用镁质护炉料，其中，所述镁质护炉料含有氧化镁、碳以及碳化硅和硅的组合物，且所述碳化硅和硅的组合物、所述氧化镁以及所述碳的含量的重量比为1∶10～15∶2～4，以及以该镁质护炉料的总重量为基准，所述碳化硅和硅的组合物的含量为1～4.5重量％。采用本发明的转炉用镁质护炉料的强度高，可以直接进高位料仓，如每炉添加溅渣前渣量的3～5重量％即可满足溅渣护炉要求，实现了炉衬镁砂的再生利用。
摘要（英）：

The invention discloses a magnesian furnace protection burden for a converter. The magnesian furnace protection burden contains magnesium oxide, carbon and a composition of silicon carbide and silicon. Weight ratio of the composition of silicon carbide and silicon to magnesium oxide to carbon is 1:10-15:2-4. With the total weight of the magnesian furnace protection burden as the standard, the content of the composition of silicon carbide and silicon is 1-4.5 wt%. Strength of the magnesian furnace protection burden for the converter is high. The magnesian furnace protection burden can directly enter an overhead bunker. For example, slag splashing requirements can be met if the magnesian furnace protection burden which accounts for 3-5 wt% of the slag amount before slag splashing is added into each converter. Thus, recycling of furnace lining magnesia is realized.
