Method for enhancing thermal shock resistance of low-carbon magnesium-carbon material
The invention discloses a method for enhancing thermal shock resistance of a low-carbon magnesium-carbon material. The method is characterized in that silicon carbide ceramic waste is used for replacing magnesia fine powder when the low-carbon magnesium-carbon material is prepared, and the thermal shock resistance of the low-carbon magnesium-carbon material is enhanced through valuable componentsin the waste. The specific preparation process is similar to that of a traditional magnesium-carbon material, and no extra complex process or new cost is needed. Silicon carbide also belongs to a high-melting-point compound, so that the high-temperature performance of the magnesium-carbon material is not influenced while the thermal shock resistance is improved. Meanwhile, because the cost is lowand the method is simple, the method is very suitable for industrial production, and has a certain economic value.
一种增强低碳镁碳材料抗热震性的方法，其特征在于，在制备低碳镁碳材料时用碳化硅陶瓷废料替代镁砂细粉，通过废料中的有价组分增强其抗热震性。具体制备过程与传统镁碳材料类似，无需额外的复杂流程或新成本。由于碳化硅也属高熔点化合物，在改善抗热震性的同时，并不会影响镁碳材料的高温性能。同时，因为成本低廉和方法简单非常适合放大到工业生产中，有一定的经济价值。
