Ball Mill Ball and Ball Mill Liners In order to properly select the temperature and time of the destabilization point, it is necessary to grasp the isothermal transformation curve of secondary carbide precipitation. There is no essential difference in the isothermal transformation curves of the three components of the ball mill ball mill and the ball mill liner alloy. The incubation period for the precipitation of secondary carbides is generally around 20 minutes, and the short incubation period occurs between 880°C and 900°C. . Ball Mill Ball and Ball Mill Liners In order to obtain sufficient secondary carbides, the required holding time at 900°C will decrease as the ratio of chromium to carbon decreases. It is worth noting that when the desorption treatment is carried out at a higher temperature, since the solubility of carbon in the austenitic ball mill accessories increases, a longer holding time is required in order to obtain the same amount of secondary carbides.
Precipitation of Secondary Carbide During Ballast Mill Ball and Ball Mill Lining
Precipitation of Secondary Carbide During Ballast Ball Ball and Ball Mill Lining Process Precipitation and dissolution of secondary carbides in the matrix during the ballast ball ball and ball mill liner lining are also directly demonstrated by the amount of change. The effect of holding time on the amount of secondary carbides in the matrix when the balls of the ball mill and ball mill liner show three kinds of Cr15 ball mill balls and ball mill liners with different carbon contents are treated at different temperatures : . The amount of secondary carbides continued to increase during the heat preservation period of 850°C, 900°C for 1000 minutes, and 1000°C for 700 minutes when the carbon-containing 1.87% ball mill and ball mill liner samples were used. The amount of secondary carbides in the samples of 2.47%C and 3.38%C increased after 300 minutes of incubation, while there was a decrease in secondary carbide halo in the three groups of ball mill and ball mill lining specimens after incubation for more than 300 minutes. This indicates that the chromium-carbon alloy is lower than that of the alloy, and even at a lower processing temperature, the long inter-deep heat insulation may cause some secondary carbides to re-dissolve in the austenite.
