Nickel-based alloy powder material for repairing crystallizer foot roller and repairing method

[0023] When the base material of the crystallizer foot roll is 2Cr13 and the size is , the repair method is:

[0024] ① Rough turning: measure the size allowance of the foot roll, turn the foot roll to be repaired, and turn to

[0025] ②Pre-flaw detection: Carry out coloring flaw detection and ultrasonic flaw detection on the turned foot roller to ensure that the turned roller has no cracks, pores, inclusions and other defects.

[0026] ③Laser cladding: The foot roller is repaired by laser cladding. The cladding layer consists of two layers. The base layer is iron-based alloy powder, and the functional layer is clad on the base layer. The material of the functional layer is nickel-based alloy. Powder; cladding of 1mm on one side of the primer layer and 1.5mm of cladding on one side of the functional layer.

[0027] ④Finish turning: turning the cladding layer to

[0028] ⑤ Grinding: Finely grind the surface of the foot roll to

[0029] ⑥ Post-flaw detection: Carry ou...

[0034] When the base material of the crystallizer foot roll is 42CrMo, the size is , the repair method is:

[0035] ① Rough turning: First measure the size allowance of the foot roll, then turn the foot roll to be repaired, and turn to

[0036] ②Pre-flaw detection: Carry out coloring flaw detection and ultrasonic flaw detection on the turned foot roller to ensure that the turned roller has no cracks, pores, inclusions and other defects.

[0037] ③Laser cladding: The foot roller is repaired by laser cladding. The cladding layer consists of two layers. The bottom layer is iron-based alloy powder, and the functional layer is clad on the bottom layer. The material of the functional layer is nickel-based. Alloy powder; cladding of 1.1mm on one side for the base layer and 1.6mm for one side of the cladding of the functional layer.
