Name: Converter tilting reducer Material: Q345 (low alloy high-strength structural steel) Basic situation: Since the reducer has been used for as long as 10 years, the outer ring of the shaft and the inner ring of the gear have been severely worn, the keyway is missing, and it has endured huge torque for a long time, causing some Requirements for repairing seriously damaged contact surfaces: 1. There are no cracks, holes, pores and other defects in the metallography, 2. The bonding performance between the base material and the cladding layer is good, 3. The hardness of the cladding layer is similar to the base material. 4. The hardness of the gear additive is HRC56-62 above 3mm.

Basic situation of the connecting shaft of the terminal reducer in the steel plant

Name: Converter tilt reducer

Material: Q345 (low alloy high strength structural steel)

Basic situation: Since the reducer has been used for 10 years, the outer ring of the shaft and the inner ring of the gear have been severely worn, the keyway is missing, and it has been subjected to huge torque for a long time, causing serious damage to some contact surfaces.

Repair requirements:

1. There are no cracks, holes, pores, or other defects in metallography;

2. The base material and cladding layer have good bonding properties;

3. The hardness of the cladding layer is similar to that of the base material;

4. The hardness of the gear additive is HRC56-62 above 3mm.
