一种有芯感应电炉用炉衬材料及其制备方法
摘要：
本发明涉及炉衬技术领域，且公开了一种有芯感应电炉用炉衬材料，包括以下重量份的原料：高纯度石英砂100份，镁砂粉5～7份，氧化锆0.08份，硼酸0.8～1.2份，所述高纯度石英砂按重量百分比包括以下粒度的高纯度石英砂：粒度为5～10目的高纯度石英砂15～25％、粒度为15～30目的高纯度石英砂15～25％、粒度为35～40目的高纯度石英砂15～25％。该有芯感应电炉用炉衬材料及其制备方法，通过使用高纯度石英砂，并合理配比不同的粒度，中频炉炉衬气孔率小，致密性高，烧结性好和耐激冷激热性好，本发明炉衬材料耐火度高于1720℃，软化温度高于1700℃，具有良好的热态稳定性、化学稳定性和机械性能，绝缘性好，施工能好和烧结性能好。
摘要（英）：

The invention relates to the technical field of furnace linings and discloses a furnace lining material for a core induction furnace. The furnace lining material comprises the following raw materialsin parts by weight: 100 parts of high-purity quartz sand, 5-7 parts of magnesia powder, 0.08 part of zirconium oxide, and 0.8-1.2 parts of boric acid. The high-purity quartz sand comprises the following high-purity quartz sand in percentage by weight: 15 to 25% of high-purity quartz sand with a particle size of 5 to 10 meshes, 15 to 25% of high-purity quartz sand with a particle size of 15 to 30 meshes and 15 to 25% of high-purity quartz sand with a particle size of 35 to 40 meshes. According to the invention, through usage of the reasonably proportioned high-purity quartz sand with differentparticles sizes, an intermediate frequency furnace lining has the advantages of small porosity, high compactness, good sinterability, good chilling resistance and good heat shock resistance; and the furnace lining material has refractoriness of higher than 1720 DEG C, a softening temperature of higher than 1700 DEG C, and good thermal stability, chemical stability, mechanical properties, insulativity, construction performance and sintering performance.
