Furnace bottom construction method of induction furnace

A. The thickness of the excellent layer is 100mm, and then it is flattened. Use the vibrating fork to fork from the outer circumference to the inner fork 3-4 times, which takes 5-10 minutes. Pay attention to the principles of order, cross, and uniformity. Then use a circular flat hammer to vibrate from the center to the outer circumference in a spiral form 2 times, which takes 3-6 minutes. The flat hammer requires the second hammer to press 1/3 of the excellent hammer and does not miss the hammer. After tamping, use a fork to scrape the surface loose by 5-10mm to facilitate the interlocking of layers and prevent delamination.

b From the second floor to the bottom of the furnace, repeat the above operation.
