High-aluminum silicon carbide refractory brick and preparation process thereof
The invention discloses a high-aluminum silicon carbide refractory brick and a preparation process thereof, and relates to the technical field of refractory bricks. Specifically, the high-aluminum silicon carbide refractory brick comprises an inner core and heat dissipation layers wrapping the two sides of the inner core. The ingredients of the inner core are high-alumina vanadium soil, silicon carbide, a filler, a coating material and a binding agent, the content ratio of the high-alumina vanadium soil to the silicon carbide to the filler to the coating material to the binding agent is 10: 1:1: 0.5: 7; and the ingredients of the heat dissipation layer are rock wool, copper aluminum alloy, a foaming agent and a matrix, and the content ratio of the rock wool to the copper aluminum alloy tothe foaming agent to the matrix is 1:1:1:5. According to the high-aluminum silicon carbide refractory brick and the preparation process thereof, through the structure of the inner core and a heat dissipation layer used for protection, the strength, hardness, compression resistance, fire resistance, high temperature resistance and other standards of the refractory brick are achieved, the refractory brick has waterproof, water absorption, high heat dissipation and other properties, so that the product quality of the refractory brick is greatly guaranteed, and the refractory brick is delayed ininternal cracking and not prone to breakage when being resistant to high temperature or after being resistant to high temperature for a long time.
本发明公开了一种高铝碳化硅耐火砖及其制备工艺，涉及耐火砖技术领域，具体为内芯和包覆在两侧的散热层，所述内芯的配料为高铝钒土料、碳化硅、填料、覆料和结合剂，按含量比计，高铝钒土料：碳化硅：填料：覆料：结合剂＝10：1：1：0.5：7，所述散热层的配料为岩棉、铜铝合金、发泡剂和基质，按含量比计，岩棉：铜铝合金：发泡剂：基质＝1：1：1：5。该高铝碳化硅耐火砖及其制备工艺，采用内芯加用作保护的散热层结构，既达到了耐火砖的强度、硬度、抗压性能、耐火、耐高温等标准，又使得耐火砖兼具防水、吸水、高散热等性能，极大地保证了耐火砖的产品质量，使得耐火砖在耐受高温时或在长期耐高温后，内部开裂延缓，不易碎开。
