Low-creep clay refractory brick for carbon furnace and preparation method thereof
The invention provides a low-creep clay refractory brick for a carbon furnace and a preparation method thereof. The low-creep clay refractory brick for the carbon furnace is prepared from the following raw materials in percentage by weight: 28-32% of andalusite aggregate, 13-17% of andalusite powder, 8-12% of emery powder, 18-22% of third-grade aggregate, 6-10% of kyanite powder, 6-10% of third-grade high-aluminum powder and 7-11% of a binding agent. The preparation method comprises the following steps: (1) crushing the raw materials; (2) preparing a green brick; and (3) putting the prepared green brick into a kiln, and conducting sintering at 1460 DEG C to obtain a finished product. The low-creep clay refractory brick for the carbon has the characteristics of high refractoriness under load, high high-temperature breaking strength, low porosity, good creep resistance and the like, and the performance of the low-creep clay refractory brick can completely meet the use requirement of a carbon furnace.
本发明提供一种碳素炉用低蠕变粘土耐火砖及其制备方法。所述碳素炉用低蠕变粘土耐火砖由以下重量百分比的原料制成：红柱石骨料28～32％、红柱石粉13～17％、刚玉粉8～12％、三级骨料18～22％、蓝晶石粉6～10％、三级高铝粉6～10％、结合剂7～11％。制备方法包括以下步骤：(1)原料粉碎；(2)制砖坯；(3)将制得的砖坯入窑，1460℃烧结，即得成品。本发明的碳素用低蠕变粘土耐火砖，具有荷重软化温度高、高温抗折强度高、气孔率低、抗蠕变性能好的等特点，其性能完全能满足碳素炉的使用。
