Graphene reinforced aluminum-carbon sliding plate material and preparation method thereof
The preparation method comprises the following steps: by taking 25-37wt% of tabular corundum particles with the particle size of 2-3mm and 28-34wt% of tabular corundum particles with the particle size of more than or equal to 1mm and less than 2mm as aggregates, and 27-38wt% of tabular corundum fine powder with the particle size of less than 0.088 mm, 2-5wt% of elemental Si powder and 1-3wt% of modified graphene nanosheets as matrixes, putting the aggregates into a stirring machine, uniformly stirring, and uniformly mixing to obtain a mixture; adding liquid phenolic resin accounting for 4-7wt% of the sum of the aggregate and the matrix, mixing, adding the matrix, and uniformly stirring; and carrying out mechanical pressing molding, carrying out heat treatment at the temperature of 200-250 DEG C, carrying out heat preservation at the temperature of 1220-1400 DEG C under the carbon burying condition for 5-8 hours, and naturally cooling to obtain the graphene reinforced aluminum-carbon sliding plate material. The prepared sliding plate material has the advantages of being good in oxidation resistance, excellent in slag resistance, high in strength and good in thermal shock resistance and can be used for a continuous casting system.
