Castable for blast furnace main iron runner working layer iron slag part
The invention discloses a castable for an iron slag part of a working layer of a main iron runner of a blast furnace, and mainly solves the technical problems that a refractory material of the iron slag part of the working layer of the main iron runner of the blast furnace is easy to erode and short in service life. According to the technical scheme, the castable for the iron slag part of the working layer of the main iron runner of the blast furnace comprises the following raw material components in percentage by weight: 40%-46% of ZrO, 10%-25% of SiO2, 10%-25% of Al2O3, 15%-20% of SiC, 1%-2% of C and 0.5%-1.0% of phosphite ester, and the sum of the weight percentages of all the components is 100%. The volume density of the castable is 3.0-3.2 g/cm < 3 >. The molten iron throughput of a blast furnace main iron runner iron slag part working layer prepared from the castable is greater than or equal to 200,000 tons.
本发明公开了一种高炉主铁沟工作层铁渣部位用浇注料，主要解决现有高炉主铁沟工作层铁渣部位耐材易侵蚀、使用寿命低的技术问题。技术方案为，一种高炉主铁沟工作层铁渣部位用浇注料，其原料组分的重量百分比为：一种铁沟渣线浇注料，其化学成分的重量百分比为：ZrO：40％～46％，SiO2：10％～25％，Al2O3：10％～25％，SiC：15％～20％，C：1％～2％，亚磷酸酯0.5％～1.0％，各成分的重量百分比之和为100％。本发明浇注料体积密度为3.0～3.2g/cm3。用本发明浇注料制备的高炉主铁沟铁渣部位工作层，铁水通过量≥20万吨。
