Embodiment 1
[0025] a. Assemble the mold and put in 15 grams of Al 2 o 3 -Na 2 O-B 2 o 3 -SiO 2 Basic vitrified bond, compacted with a press plate.
[0026] b. Take the center line of a single corundum abrasive grain with a radius of 1 mm as the center line to mark a horizontal line, and draw two upper and lower marks at a distance of 2 / 3 mm from the horizontal line.
[0027] c. Insert the lower end of the above-marked corundum ball abrasive grains into the middle of the vitrified bond block in step a, and press the upper end mark of the abrasive grains into the bond block completely.
[0028] d. Carry out belt mold curing for the mold assembled above, that is, raise the temperature from room temperature to 250°C at a heating rate of 5°C / min and keep it warm for 1 hour, then raise the temperature to 250°C at a heating rate of 4.5°C / min and keep it warm for 2 Hours, the temperature was raised to 720°C at a heating rate of 5.5°C / min and kept for 2.5 hours, and then cooled to room tempe...
