Abstract

The invention relates to a centrifugal casting roller coating and a preparation method thereof. The centrifugal casting roller coating is characterized by comprising the following compositions in percentage by mass: 12 to 15 percent of zircon powder, 8 to 10 percent of quartz powder, 8 to 10 percent of bauxite, 0.3 to 0.6 percent of silica sol, 0.1 to 0.4 percent of sodium carboxymethyl cellulose, 0.15 to 0.35 percent of alkyl benzene sodium sulfonate, 0.15 to 0.35 percent of sodium sulfate, 0 to 0.02 percent of n-butyl alcohol, 0 to 0.02 percent of n-octyl alcohol, 0.10 to 0.18 percent of fatty alcohol polyethenoxy ether, and the balance being water, wherein the mass percentage of the zircon powder + the quartz powder + the bauxite is more than or equal to 30 percent and less than or equal to 35 percent, the mass percentage of the alkyl benzene sodium sulfonate + the sodium sulfate is more than or equal to 0.35 percent and less than or equal to 0.55 percent, and the mass percentage of the n-butyl alcohol + the n-octyl alcohol is more than or equal to 0.02 percent and less than or equal to 0.03 percent. The coating is used for centrifugal casting roller production after stirring, grinding and sieving, and has good use effect.

Description

technical field [0001] The invention relates to various coatings for casting rolls and a preparation method thereof, in particular to a coating for centrifugal casting rolls and a preparation method thereof, belonging to the technical field of roll manufacturing. Background technique [0002] Rolls are the main consumable spare parts in steel rolling production. In order to improve the quality of rolls and reduce the production cost of rolls, domestic and foreign roll companies generally use centrifugal casting instead of traditional static casting to produce high-performance wear-resistant rolls. In roll centrifugal casting, due to the centrifugal force, the metal casting mold is prone to wear and thermal fatigue under the centrifugal force of the molten metal, resulting in shortened service life of the casting mold. In order to prolong the service life of the metal mold, adjust the cooling rate of the roll and improve the surface quality of the roll, the metal mold used in...
