Abstract:
    The explosive hole burning process for composite roller includes the following steps: 1. regulating the ball valve for the oxygen pressure within the initial maximum oxygen pressure of 102 Pa; 2. regulating the pressure to 54 Pa and preheating the inner layer of the composite roller completely when the distance of the bottom of the hole to the double layer interface is within 50mm; 3. preheating the interface for 10-15 min before further burning hole; 4. restoring the oxygen pressure to 102 Pa after the said distance exceeds 50mm until reaching the set depth of 600-800mm; and 5. repeating the steps 1-4 to burn the other holes. The said process is safe, reliable and without bursting crack.
